I don’t drink caffeine to wake up, I wake up to drink caffeine 😂
😂😂😂 same!!!
😂
Same here 😂
My kind of man !!!
Same here😂😂
after 30 days off caffine my sleep improved. blood pressure dropped. teeth grinding stopped. electrolyte balance fixed. alertness increased in the morning; not only did i feel more alert, my productivity increased probably 2x. hard drop in the evenings disappeared. also my ability to prioritize goals and make "good" decisions improved. as a result of all that i finally started losing weight very easily after 12 years of struggling.
Dang sounds like a lot. Grateful I don’t suffer for any of those ailments because I love my organic single origin coffees. Glad simply dropping coffee fixed all those things for you
@@rasbe420some of many people don’t process coffee the same and turn into angry psychos on or off it.. but it’s insidious because you don’t associates the cups you drank yesterday with exhaustion when you wake up and anger during the day. The first few cups don’t make you feel that way, so by the time you realize you may have a problem, you are already addicted and can’t quit. It plays with your thinking process, so you forget how bad in made you feel and reach for it for the euphoric and stimulating effect again.
And he get some superpower wwwwwwhat .....? 😅
So caffeine was driving up cortisol making it hard to lose weight.
I totally agree but can't quit
Quitting caffeine, was the best decision I have ever made. Prior to quitting, I suffered social anxiety, fatigue, lack of motivation, and so many things. I made the decision to stop, and let me tell you it wasn't as easy as I had read and thought. Yes the headaches vanished in the first 2 weeks, I was still lethargic, depressed, and did not have motivations for anything. After about 3 months or so I started to feel normal again, and at around 6 months I feel like a child again, full of energy, focus, motivation, cheerfulness, its an amazing feeling. I made the conclusion that on the contrary of some research claims that it only take 2 weeks of withdrawals, some take much more time specially me who drank 3 cups of coffee a day. Now years since I stoped I still feel so great, its a bless.
I quit coffee recently. I’ve drank it since I was a little kid and for years I thought I had severe anxiety. Then once I factored out the caffeine, almost all my anxiety symptoms vanished. I’ll still enjoy a cup of coffee from time to time but it’s definitely not a routine.
LITERALLY ME!!!
@@dianastalkshow a lot of people relate to us
MY ANXIETY LIFTED AFTER I STOPPED COFFEE.
I wish it was that simple for me but I just remembered how I rarely ever drank caffeine as a kid but still had anxiety nonetheless. Maybe it contributes to the problem but definitely isn't the cause in my case. Generalized anxiety is a bitch.
Yeah, I was a coffee drinker when I was a kid too. However I never experienced anxiety from it and as I got older the quantity and concentration of it got higher and higher to the point that I looked like I was tweaking out as my fine motor skills became garbage. I can't drink coffee now and, man, do I wish I could go back to drinking a liter of max filtered coffee. It was the bomb.
To whom it may concern: If you are trying to quit drinking coffee but suffer with terrible headaches. SWITCH TO BLACK TEA or half caffeine coffee. Don't try to just quit but lower the amount of caffeine by half for about two week. Then you can stop with no headache! Took me years to figure this out.
One should discriminate it's type,Biology,quality,safety and other factors w/h are controversial or?
Cacao is better solution
I've done this too. Switched to black tea for a week then green tea for a few days. Didn't need caffeine anymore. No headaches. Worked great
Coffee is not just made up of caffeine. This is a big mistake if you want to quit drinking coffee. It has 100s of compounds that are not in the black tea. This is why even if you drink black tea instead of coffee people still get headaches as you’re not only “addicted” to caffeine but also other compounds in coffee. And coffee is not a bad thing if you’re not drinking more than a a few cups a day. Coffee has A LOT of antioxidants people don’t know this. Black Tea also does have some antioxidants but it doesn’t contain as much as coffee. Cocoa also has a lot of antioxidants as well as caffeine but again, not the same as drinking coffee. If you want to quit coffee you can gradually reduce drinking coffee. But drinking tea or other drinks is not going to make you feel better as you experience withdrawal as people get dependent on the coffee which is made up of 100s of compounds not in tea or any other drink, and not just caffeine.
@@KittenBowl1 slowly reducing the amount of coffee absolutely did not work for me. I tried many many times. The headaches were unbearable. Switching over to black tea worked for me when nothing else did. That was my experience and I stand by it 100%
My dad, who passed away a year ago, would've loved this channel and this specific video. Awesome work, fellas.
I'm so sorry for your loss. I'm hopeful you'll be reunited with your dad soon. Now let us pray 🙏.
A year later and I hope you are doing well mate
This channel is a huge gift. Awesome how he's breaking it down and helping the viewer make connections with things they may know already.. super work
In 2012 I first learned that caffeine can be used to treat pain. I was hospitalized and had to undergo a spinal tap. Following the procedure, I developed a massive headache which came on whenever I sat up in bed or if I tried the stand. Interestingly, there was no pain whenever I was laying down. For over a week they administered almost every narcotic pain meds they could possibly find, but to no avail. Then one day a doctor said to the other doctors on the team, "Did anyone try caffeine?" They got the caffeine and hooked it to the IV, and BAM, within 15 to 20 minutes the headache went away and never bothered me for the remaining 30 days I spent in the hospital.
The Army treated all complaints with two things. One was aspirin, phenacetin and caffeine. Cures many complaints. The do gooders decided that caffeine was bad, bad, bad for you and had it removed from most drug combos. The other thing the Army issued by the vat, ahem, I mean the pint was something called G.I. Gin. Codeine was the opportive agent.
What you described was caused by a spinal CSF leak. This can be somewhat common in women who get epidurals. They normally do a blood patch to try to fix the leak but if you're on anticoagulants, it won't work. It usually resolves itself within 10 days if nothing else corrects it before then.
Yes, there are several studies confirming coffeine consumption helps with headaches. In more severe cases it can be paired with Aspirin for a stronger effect!
That's why Excederin puts caffeine in their pain killers. That's also why Midol - for menstruation - has caffeine in it.
@@IMWeira Codein is adictive drugs.
I started doing a 3 month caffeine break/tolerance reset on January 1st (I was drinking about 200-300 mg of it a day) and the third day of not having caffeine I had constant headaches for almost two weeks!! But now I’m feeling good without it, and noticing the affect different food has on my energy levels. Crazy to see how addictive caffeine is 🙌🏽
I also do this on a regular basis. I think it’s good to reset your tolerances about once a year. And after that break the coffee tastes wonderful again and a small cup is enough to boost your morning (instead of 2 huge mugs:)
Good luck with the withdrawal migraines😬
I gave up coffee when we were trying to get my partner pregnant, as we were told there are some links. I had no withdrawal cravings for caffeine, but the withdrawal headaches were nasty by golly I suffered for nearly 2 weeks. I never went back to drinking as much caffeine afterwards, mostly just occasional decaf and green tea now.
@@jorgesuza8486 withdrawal migraines?
@@avilacanario yup i am taking apprx 400mg a day and i wanted to stop for a month so i did and got the absolute worst headaches of my life
What a coincidence, I just finished drinking my coffee rn. 😂😭
😂
They’re watching you 👁👁😂
I’m drinking mine rn

I love how this doctor explains everything so plainly so the common person can understand it!!
As someone who has struggled with long term depression, caffeine has been a blessing. A couple cups of coffee lift me out of laziness and help bring focus to my scattered brain.
Thanks for this. I quit caffeine for a year. No good. Suffered constant migraine/ tension headache. Started back caffein with exercise and EDM feeling sooo good.
If you are depressed because you believe in death, get the book Hands of Light. A physicist, Barbara Brennan, wrote it in 1987. We can't die because we are constantly being created.
@@hummingbirdbumblebee4618 yeah, yeah. Every night I drift away, wondering if I'll be born again in the morning. It's this life that gets depressing. I look forward to moving on.
@@ShakthiPrasadGS exercise makes a notable difference for me. AM workouts give my energy the added boost it needs.
@@DADela-ht6ux According to physics, quarks are constantly bursting forth spinning billions of times a second as 3 points of light forming protons and neutrons. This is how we are constantly being born. If not for quarks spinning into atoms, the 7 billion, billion, billion atoms we consist of, then we would not have the next heart beat or breath. I am not religious. There was never enough information to be found. Our literal souls are creating these quarks of light into the atoms of light we are. At what is called death, we pop out of these bodies of dense energy to see we have always existed in other dimensions that show us the electrical beings we are. Some people like me want to relieve the burdens others feel when they can only see so far. Apparently, this is my job on earth.
I just completed 1 year of no caffeine. While it did take a couple weeks to kick the withdrawls, I felt good overall. I instead supplemented with vitamins for the entire year. B12 was a key aspect of this regiment to help convert food into energy, and I highly recommend fitting that into a daily regiment. If you are looking to kick caffeine, look towards B12 as a start.
How you take those b12 daily, what food and suppliment you consume?
Hey, I'm just wondering why supplement with B12? As in the meat and eggs there is plenty of B12. Correct me if I'm wrong, of course 🥚
I've been drinking energy drinks with 300mg of caffeine everyday for YEARS, and I'm already tired all of the time. I'm scared of how bad my withdraws will be especially cuz I have kids
@@333kireinahime just take 1 week of vacation and focus on just resting, sleeping, surely after 1 week the symptoms will have faded to some extent
@@metallica961025 not plenty.
There are many meat eater who have low rates of b12, so supplementation for most is a good idea. B12 is one of the view supplements who has shown again and again that it is save to take unlike for example alot of multivitamins
I quit caffeine two years ago. I quit coffee first, then tea. The first thing I noticed was how my sleep improved within a few months, followed by an increased level of energy. About five years ago I also quit soft drinks, this also brought many health benefits. I don’t intend to drink coffee again; however, I do have the occasional green tea if I visit a friend or go for a meal (green tea has some caffeine). Mint tea is always an option too. I recently read about caffeine induced anxiety, something I’ve seen manifest in many people. I’m not saying everyone should quit caffeine, though it would be beneficial, I’m saying people should moderate their caffeine intake. One caffeine drink per week or per day is sufficient, anything over one per day could lead to health problems.
Excellent job. I'd love to stop using caffeine but I'd have to stop using caffeine to do it 🤣🤣. But seriously though, thanks for sharing your experience, it actually makes it more appealing to know that you actually noticed the results. At times my caffeine intake has bordered obscene as I work nights and it's been a part of my routine for many years. I'm in my mid fifties now and I'm relatively fit, at my ideal body weight, and I don't indulge in any drugs or alcohol by choice. I know I could give it up, because I quit smoking around 15 years ago and I battled that for several years before I finally quit for good. I never thought I would ever consider giving up caffeine but I have high blood pressure and have noticed that my hands get Shakey when I drink too much. It doesn't make me feel anxious necessarily, but it is embarrassing to see my hands shake and others notice. I have actually gone days before without using caffeine when not at work and honestly other than my hands no longer shaking I can't tell any difference. I guess I have used it so long that it doesn't have much effect on me as a stimulant anyway. It's probably just a bad habit I should drop. Thanks again for your insight, most helpful.
👍👍👍
@@nurzrachit7133 You're welcome. My caffeine intake was excessive too, I'd drink coffee even at night, up until around midnight. It took me a few years to ween myself off, it's not easy, especially if your social circle spends a lot of time in coffee shops! I would choose a hot chocolate some days, other times it would be a mochaccino. I've worked in teaching so I can relate to those 'shaky' hands, seen it in many teachers, their stress doesn't help either. I knew one lady that would have 20 cups of coffee per day! I think it's good to ween off caffeine no matter what age you're at, the benefits are always going to be seen sooner or later. I hope you get to switch to hot chocolate or decaf too! Cheers!
Congrats for that! I know that it's very hard to give up caffein. The first 2-3 weeks could be very uncomfortable. Unfortunately I have gone back to coffee. I changed to decaf version, and a small amount of regular before workout. But the fact is when I forgot the pre workout coffee I feel the workout is worse. At the beginning I performed better in the gym, but later just feeling weak without coffee and normal with it. It's crazy your body how can addict to it.
Thank you. I started drinking tea because it felt calming. Oddly enough I noticed I had more anxiety. It’s the caffeine!
I drink black coffee throughout the day. And I don't drink soda very often. First week of every month I cut out coffee completely and my body does its usual withdrawals. Pretty fun :D
Interesting method! Made me chuckle, might have to try it
I only get migraines when I skip a coffee with caffeine.
I do it every 2 weeks as my body completely ignore the caffeine pretty quickly, really a bummer. That's why I stopped drinking it nowadays, as every times I experienced withdrawal it took me 2 unproductive days before it goes away...
I have absolutely no clinical, academic, or other medical ambitions. I was fascinated with anatomy in high school and I learned a great deal from our physiology class, and the research I did on my own. My family has too many doctors, nurses, etc., so I opted for a career in computer science. I am still intrigued by anatomy - and each video I watch with you explaining things makes me want to take a course at your school just for the experience and the in-depth knowledge. You have an amazing brain, Jonathan - how could anyone NOT retain all that knowledge with the way you explain it?. Keep up the good work!
I’m retired I guess. I wake when I like. My husband and I have a coffee ritual. Grinding the beans and putting them in the
Coffee press. We watch the news together and decide what the farm needs us to do for the day.
Would love to see a video on how artificial sweeteners affect our body. There's so much contradicting information about it that it's hard to really understand what to believe. Especially on a controversial aspartame. :)
Yeah
Agreed. There needs to be more discussion about this.
That would be a very short video cause they pretty much don't. Unless you take a bag of it and binge eat it.
They fuck you up. That's all you need to know.
@@eveythingthatsadam Can't find any evidence on that.
There are credible theories to suggest that coffee played a huge roll in the age of enlightenment. Humans moved from using depressants and sedatives to stimulants. Fantastic reads. Thank you for the videos!
Ditto! I can recommend Food of the gods by Terrance McKenna. He also talks about the politics/wars/slavery/trade/lobbying driving the history of people and substances, which I found really interesting
Food Theory’s coffee video
I drank a lot of coffee over the years but it used to make my anxiety a lot worse. I gave up caffeine almost 7 months ago and I feel much better. I occasionally drink decaffeinated and it still makes me a bit jittery.
I said the same thing to a neurologist once that my Anxiety was still bad and I got the jitters even after a cup of decaffeinated coffee only to be told it still has Caffeine in it 🤦🏻♂️😂 Just not as much as normal coffee.
Yes - people with anxiety disorders should not drink caffeine. I’ve felt so much better since quitting.
Decaf coffee still have caffeine in them
@@pembalapugg
ya, i releases stress hormones in the body. the same thing that happens to your body when you're in fear or anxious.
My older brother grew up with ADHD and the doctor had him actually eat coffee beans when he was a kid, which actually worked. I'm told the effects of caffeine were different for him because he had ADHD. Would love to know why that is.
I have heard the same-give coffee to kids with ADHD.
My cousin said the same thing who has ADHD
As someone who has ADHD, coffee is essentially a replacement for medication for me. it makes me more focused and calm without all the "negative" side effects.
It's a stimulant, and in the normal person, stimulants cause jitters, but for ADD people, it helps the frontal lobe focus.
@@tobinalmackx8626 that’s exactly what my brother says as well. I remember the reason the coffee was suggested was because when he was on the normal medication, he developed an aggressive twitch and a tick. The coffee practically worked a miracle for him. Went from the kid that couldn’t read aloud in class, to someone that didn’t stutter a single word.
The fact im able to learn and understand how caffine effects my brain (and body) on a molecular level after watching a casual YT video is actually quite amazing. Great work explaing this!
Videos like this, if taught in a school setting in conjunction with a lab, would be such an effective learning tool
You are a natural teacher! I was an elementary teacher for 17 years and I have the most respect for teachers who are able to simplify matters into understandable and creative formats using as many of the senses as possible to increase our learning capacities and store data in long term memories. Thank you so much for these wonderful videos!
Once again, a most interesting video. I’m a retired clinical nurse. I was an educator in occupational health. So I’m partial to your style and find your videos enjoyable. Congratulations. You use this medium to great affect. Excellent. I’m sure there’s plenty more of us that feel the same way about your presentations and the positive effect they’re on health education. Cheers. Colin
Thank you 😊 for your medical service to humanity. 💪
Hey, could you do video about what sugar does to your body? And if there's any difference between refined sugar and "healthy" sugar? Would be also cool if you could include long term effects of each substance you discuss. Would love to see, for example, how cannabinoids (or sugar for that matter) can affect us after years of indulgence.

@@gina_mocafitnessactivewear1192 this guy is not a good source. Not saying sugar is good, but he’s just trying to pick for his narrative on ketogenic diet.

@@Rileyed I don’t see science fictional books as a good source, nor waiting for an invisible man in the sky to come and help us.
There is no safe level to eat of sucrose (table sugar) or brown sugar, or honey, or high fructose corn syrup. It's entirely too concentrated amount of fructose that absolutely hammers the liver, since fructose cannot be used like glucose. Table sugar is 50% glucose, 50% fructose. Fructose from fruit you have to chew up with your teeth is perfectly safe, because it takes time to absorb into the liver; so it does it slowly at a safe rate. Honey is just as bad as table sugar. It is about 40% liquid fructose. It's just too much work for your already overworked liver to process. Your liver already performs over 500 crucial tasks, so take it easy on your liver.
with my exams coming up and my coffee intake skyrocketing, this was certainly a very enlightening video
Good luck on your exams!
Try Glucose tablets or a bottle of coke during your exams .... hmmmm .... yummy!!
Doctor, Doctor, why do I learn so much more from your than all my teachers combined? Thank you so much.
I came here looking for a reason to stop drinking caffeine but the opposite happened. Thank you!! 😊
I began drinking coffee since I struggle a lot with mental health, there is a hint I may have ADHD, so I decided to start drinking. It does wonders to my mental state. It lowers my social anxiety to an acceptable level where I can actually function. Turns off suicidal thoughts, makes me focused and willing to actually work on the things I come up with

Caffeine makes my anxiety worse. I’ve always had a sensitivity to it. I stopped for a while and now I drink decaf here and there. I just love the taste.
Try ceremonial Matcha green tea
It's a tragedy that decaf beans are not even half as good tasting. I tried. Nothing compares, so I'm limiting to once or twice a week with the real thing.
Have you found a good brand of decaf that tastes good?
@@MX-S agreed. And there’s not many varieties but after drinking it a while, I’ve gotten used to the taste. I miss my Sumatra dark roast so much 😭
@@kimberlychristy-saviano7673 I’ve tried a few different brands. They’re good enough and you get used to the taste, eventually. One of the brands I get is an organic store brand from Publix, which is a grow store in Florida. It’s decent enough. I definitely had to get used to the taste.
Watching this video about how caffeine affects the brain while sipping my daily iced coffee (: by the way thank you so much for this great content that you share with us for free! Very valuable information that I’ve always been curious about. The human body is amazing ❤️
I used to drink 2-3 energy drinks a day. The crash after they wear off was sometimes too much. I quit caffeine for 3 days and had a heavy feeling in my head followed by headaches and severe anxiety attacks.
I went back to caffeine after that but a smaller dose. Now I drink 1 energy drink a day and a soft drink for lunch. Everything seems fine -but don't try to quit cold turkey
I confess l have the same experience with it at times..
Energy drink is almost just sugar...i mean, you shoudnt worry that much about the caffeine in this case. Your simptoms are more due to the sugar itself.
When I got sick with covid I drank only water for 2 weeks and refused anything like soda and tea. And I believe I broke the caffeine addiction I had. I now only drink tea and 1 energy drink every blue moon or so
Great video! I now take a 200mg caffeine pill 3x/day, 6 hours apart, up from 2x/day, 8 hours apart when I first started. It's started to affect my sleep, and I cut back occasionally but that caffeine withdrawal headache after a few days is wicked 😣
Just discovered this channel a few days ago and loving it so far! The videos are informative and satisfy my science loving brain haha. Presenter is great and has a way of simplifying and is very engaging. Thanks for the videos!!
I quit Coffee and all caffeine 18 days ago.
I’ve had at least 3 espresso a day for the last 20 years. I’m still feeling withdrawal symptoms. It takes at least 30 days to kick the habit. I’m gonna say even a few months for someone who has a morning “ritual” built around coffee, like I did.
But I do notice I am already a nicer person.
My inner lake is the calmest it’s ever been.
🕉💟☮️
You will live longer and have more money. Great decision
Good for you!! Good luck!!
It takes more than 30 days.Quit caffeine 8 months ago but still get cravings.But very good for you.❣
I'd guess you get headaches on the first few days, especially on the first. However sugar avoidance and having more stable foods like beans is by far the more significant factor to a healthy diet.
I started to have aniexty and panic attacks stemming from family issues but when I quit coffee I was able to deal with my emotions better.
I absolutely love that I found this channel and feel like a little kid geeking over everything I'm learning. I've always been an English nerd but here I am actually learning about the human body and falling in love with science.

I had a liver disease and my doctor recommended me to drink 3 cups of coffee per day. Black coffee with no sugar, no cream. It seems that coffee somehow helps the liver cells and studies showed that could help in reducing the risk of cirrhosis.

Ikr, the human body is truly amazing, makes me want to go to med school.
A very detailed, but also easy to understand way to explain how caffeine works on a pharmacological level and this comes from a pharmacist. Keep up the great work :)

No it was not. No one cares that you peddle drugs either
@@Kevin-fy2fg let me guess: you’re 8 years old.
What about him not pointing out how it messes with vitamin D / calcium / iron to name a few ?
@@nonzenz ‘Effects of caffeine on bone and the calcium economy’ (2002): ‘The negative effect of caffeine on calcium absorption is small enough to be fully offset by as little as 1-2 tablespoons of milk’.
Are you sure it’s relevant enough?
Great video as usual! What I admire about your presentation approach is after watching this no one who drinks coffee feels attacked by the way that you presented the information nor is it given in such a way that a non-coffee drinker could boast after watching it; It’s scientifically delivered in such a way that the observer/listener can draw their own conclusions.
My personal opinion is that I believe that dependency upon caffeine can really be an issue. I’ve been drinking 2 to 3 cups daily for the past six or seven years and I know that I need to eliminate or extremely reduce the intake of caffeine based on how I been feeling about it both physically and emotionally. I am addicted to it in the sense that I have trouble picturing what a day without “needing” it would feel like. That’s a real issue. I also have a theory that it may be causing excessive tension in my muscles, which possibly may be hindering my potential mobility/flexibility (I’m a grappler so every bit counts). I’m currently reducing the amount every day and hope to quit within the next couple of weeks just to break free from the dependency.
Thank you again for another amazing video! As an anatomy and physiology geek myself, your content are top notch 👌

Thank you for this wonderful video.
I'm still unsure of how the adenosine gets into our bloodstream (and makes us relaxed/tired)
I'll watch again.... and thanks again.
You guys are great.
anatomy is mind-blowing, natural technology. growth of complex systems guided by microscopic instructions. amazing.
yess thank you!!!! please keep posting more of these, knowledge of how drugs work and affect the body is incredibly important in the world we live in. you can help so many people by showing them the damage they can do to themselves. the war on drugs didn't teach anyone why drugs are bad, just that they are.
Coffee actually helps asthma. Has helped mine and some of my family members, as well.
Another great video! Would be helpful to supplement this video with another one dealing with caffeine‘s affect on sleep. According to Michael Pollan, the author, many if not most researchers who study sleep seem to have reduced or cut caffeine use. Apparently it has a half-life of some 12 hours in the body.
12 hours is a half life of amphetamine my friend. 😅 Caffeine half life is about 4 to 6 hours max
adderall has a half life of 12hrs and caffein 6hr~

Caffeine is so underrated as an addict substance. I used to drink coffee every 2-3 days, then it became everyday, then it became 2 times a day. I feel empty if I don't drink, it's not about getting energised or waking up. It's just the need to drink
Id say 60% of that is the flavor 😋.
I have a few friends doing a 40 day fast from caffeine rn and this video really helped me understand a bit of why they might be acting different and gave me a couple ideas of how to possibly help make it a bit easier for them so thank you for this :)
The thing is that a lot of people neglect their sleep (let’s say they don’t have sleeping problems) because they know they can just drink coffee and be fine :( that’s not the ideal thing to do 🌝
I dont drink coffee often, but i found while coffee does deliver an instant "wake up" response to me, good tea (generally not bagged, but full leaf ones) keeps me focused and aware for a far longer period and it doesn't have that sudden drop off in energy that coffee gives.
I had two kids with high ADD symptoms that we used caffeine to help with the synaptic interaction. It worked beautifully. It is probably why I use coffee… plus, it is one of my favorite flavors. There is nothing more satisfying and relaxing than a good cup of coffee.
One important point of this video is that cells can respond to a treatment, in this case by increasing the number of adenosine receptors with chronic caffeine consumption. The fact that cells can alter their structure to counteract a treatment is important in understanding the basis of pharmacology. Even cancer cells are able to do this sometimes to evade cancer treatments. It is good to see this topic was discussed in relation to caffeine.
what does it mean if the cells are increasing the number of adenosine receptors? Do you need more caffeine then to get some effects?
@@rz5b1qszkdf44 exactly
@@rz5b1qszkdf44 kinda means that the body gets used to the amount of caffeine you drink and you won`t feel the effect as well as before
Could this explain why the 1 day a week I don't consume caffeine I am extremely lethargic? I normally consume 400-500mg of caffeine a day except Sundays to reset.
@@sidious501 yea definitely. I think you drink a lot of caffeine tbh. I usually drink one cup of espresso a day. I don t think it has more than 50 to 60 mg of caffeine.
Cheers to another amazing video with clear and simplified explanation! :) Thank you for this video and the way you tell what a term means so it is easily understood by the viewers like what you said about diuretic. 👍🏻
Idk but drinking coffee makes me feel so much motivated it just boosts up my confidence my focus towards my goals and if any day i don't drink it i feel less motivated i don't study much and i feel really tired..
I've an entrance xam tmrw i don't think so that leaving it rn is right but definitely I'll try to get out of the loop after my xam
moderation is the biggest issue with caffeine consumption, more than the caffeine itself. btw, thxs for these videos. this language is foreign to me. but u make it easy to understand
This explains a lot 😂 during pregnancy we tend to all of a sudden cut down the caffeine immensely and I'm just now realizing this might contribute to the already existing pregnancy symptoms of fatigue, headache, etc. Especially when you're feeling sick and all of a sudden almost never drink caffeine when you used to have several cups a day..
I would love for you to do one on how the immune system recovers after an illness. I know getting sick, and recovering creates antibodies. But, I have always wondered if the immune system is tired immediately after fighting off something and that might increase your chance of picking up the very next virus that you come across. As a family, it always seemed like we would all be healthy for months and then one of us would catch something, pass it around the family, and then immediately after we'd all catch something new.
I wanna see that too!!
Your immune system is tired when going thru the sickness, and is rested once you don’t feel sick anymore, from my understanding.
This video rocked my world! Finally a real lesson!! Ty!!!!!
Amazingly explained 👏
Thank you so much. 😊
Man u have raised my interests in medical , now it helps me in clearing neet as i got motivation from inside
Love your videos! I’m taking biology and anatomy class so these really make the classes make sense! I’m also a coffee addict, lover , so I love to learn about this.
A very important point that - though it is somewhat obvious - in that context it might have been stressed that coffee is far more complex than caffeine. There are more than 850 substances in coffee about 100 of which are neither researched nor clearly identified yet. Then there are different strains, regions of origin, processing methods, the roast ... and finally the preparation: water temperature, grind size, steeping time, agitation. Being pretty sensible to many substances and foods i want to state that i feel noticeably different after drinking same brewed coffee from different beans. Most important If a coffee tastes bitter and/or is harsh on the stomach chances are temperature and/or steep time was too high. Mostly slow artisanal roasts are much more beneficial. I once had nice tasting wild beans that caused me ocular migraine and also a Yirgacheffe that was highly motivational. Cheers! :)
Wow! 😮
I’ve only ever seen diagrams of neurons with a few dendrites. I had no idea & it makes so much sense that they can have thousands!
I am not a big fan of coffee taste (only with sugar together with some cookies,.. and that's not ideal). However coffee has helped me a lot of times when a migraine hit me. Maybe it has something to do with very low blood pressure but it definitely helps me. Once when my bp reached 79/56 and I felt really unwell, coffee literally rescued me. So for me it's a medicament :) Don't drink it regularly only when I feel unwell due to low bp, have a migraine, etc. Btw thank you for the amazing videos!! I've always dreamt of studying medicine but because I can't handle dead bodies, "cutting" any bodies, injecting needles, etc. I gave up. On here it's safe :) I learn without fainting :) Keep it up!!
Enjoy your explanations of how the body works and how certain substances like coffee affect the body! I have been a coffee drinker for many years I am 73 at this point in my life and use it as a mild diuretic! I have backed off on it slightly I used to drink a lot of coffee when I was working but now only have approximately three to four cups a day I feel this is enough to give you the energy I need to do what I need to do and I do like the taste of it. Also like the different kind of creamers to put in it, probably not the best thing to use but I look at it this way I'm 73 years old what have I got to lose! Ha ha! Ha! Thank you for making sense of it!!!

I quit using caffeine many years ago. Its effects have been positive on my health. I vow never to touch it.
Great video! It would be super interesting to see another on the caffeine's effects on the rest of the body.
i just finished writting my graduation paper on adverse effects of caffeine in teenagers. this video couldnt have come in a better time since my findings are similar to the points of your video!
that's so cool !
Glad we could help. Good luck on your paper!

Did you speak on the effects caffeine has on anxiety at all? I’m considering taking a month off caffeine to see if it improves my tendencies towards overthinking/anxiety.
This dude's communication skills are so top notch that I'm still listening while he's promoting the ag1.
Ha same!
No one ever told me this, so thank you for this video.
Excellent presentation, facts taking precedence over ego. Appreciation, from Iowa.
My father was a huge coffee drinker starting the day off with a few cups and on thru the day. He was the kindest man you'd ever hope to meet using his many skills to help anyone just for the asking. He died at the age of 90. I guess it was all that coffee that did him in.
True story.
Mayo clinic has discovered many benefits to coffee.
My father passed away at 97. Very kind & patient person & drank coffee every morning for over 70 years. He was still riding his bike in his 90's, as well as driving.
Can we just apperciate him for his best efforts of making good content for us👌

Thnaks a lot. Now I know how to reduce the symptoms of caffeine intolerance.
I use to be a heavy coffee drinker for about 15 years, but I had to cut way down on coffee. I only drink 1 cup a day now. Because, when I was drinking coffee heavily I ended up being rushed to the hospital different times for severe dehydration where one time I was so bad my hands and feet were numb and each time I could not function, I could not stand, I could not sit, and I was pale white. I looked like I was dying. I had to have fluids put into me through an IV. This video does not talk about this, but I just want to let you know what can happen to you. Coffee dehydrates you very much. so, now I plan out when and where I will have that daily cup of coffee. Sometimes I plan to have that coffee in the morning, or I wait till later in the day and order an blended annihilator coffee at Dutch Brothers.
Wow dude! Glad you figured it out brother! My thinking on being dehydrated is just to make sure you drink more water throughout the day. Did that not lessen the negative effects of having so much caffeine?
That just sounds like you weren’t drinking enough water and nothing to do with caffeine lol
Caramel kicker at Dutch bros is really good !
Yes caffeine irritates the bladder and makes you pee, therefore it can dehydrate you or act as a diaretic. Maybe not so much when your younger but especially as you get older.
@@killionaire486 right? I drink a lot of damn coffee but also a lot of water. No issues with dehydration whatsoever.
I was heavily using caffeine many years ago (as a result of stopping alcohol) and found I had a serious problem with aggression from the stress it caused. So I started taking dl phenylalanine. You don't taper off on coffee when you take it, you substitute the phenylalanine for coffee and you seriously don't want to drink any coffee while you're taking it. It eliminated the withdrawl symtoms and made me feel 100 times better than I did when drinking coffee. Not very long after I stopped taking it because I woke up feeling rested from natural sleep.
Phenylalanine is in diet coke and coke no sugar, and caffeine is in these too. Caffeine is also in milk chocolate and dark chocolate. Do not drink any coke, diet coke, coke no sugar and do not eat any milk chocolate and dark chocolate while taking Phenylalanine.
@@littlemisskimmycat78 You'd have to eat 7 oz of dark chocolate or 3 cups of milk chocolate chips to get the same caffeine as in a cup of coffee (96mg).

@@andsotheadventurebegins2030 I had a friend that did the 4 corners ride (motorcycle ride that goes east to west from a northern route and back from a southern route, and goes north to south and vice versa on both coasts. Just a big box. I shoulda said just look it up.) Anyway, a long way to say she had gotten off coffee before the ride using phenylalanine but at some stop, not thinking, ordered coffee. She said she ground her teeth for a few hundred miles from being so amped up.
The DL PHL messed with my nervous system when I tried using it to get off of caffeine.
I don't even want to remember the days when I had my withdrawal symptoms of caffeine. I felt heavily depressed and got such huge headaches that I wasn't able to do anything. Can't even imagine how hard must be to clean yourself off drugs.
I never got into caffeine with coffee and even my sweet tea intake is low. I always noticed when I was young, and this gradually became more obvious, that caffeine made kids and adults who drank it super hyper and they acted weirdly more emotional than usual. I'm in my 30s now and I still rarely drink caffeine heavy drinks and I still keep pace with those who would, if they could, pump it into their veins via IV.
I think of caffeine as liquid anxiety.
@@PeterTroutman No doubt!
I started drinking caffeine when working long hours as it was a simple pleasure, then every day after my family abandoned me. The days are long and boring, tedious and tiresome. Caffeine kept me going.
I drink reigns and bangs which at 300 milligrams of caffeine per can is practically just that lol.
I don't know how I found this video, but I want to share my experience as a heavy coffee drinker. I drink between 4 -6 cups of black coffee per day. I can drink like this several month then i can to stop drink coffee with no problemas. The first time when i tried to stop my coffee intake i had two days headaches. As many others i thought that was the typical caffeine addictive person simptom. Now lots of years later i know the problem it's not the coffee(supposing you drink good 100% arabica coffee). The real problem was the sugar because I always had my coffee with sugar. Now i don't use sugar anymore not even artificial sweeteners, just plain good black coffee and i can to stop drink the coffee any time with zero problems.
That's my boi..i also drink just 1 glass around 200ml made with 1spoon and jaggery instead of sugar...sugar is also real culprit for addiction
I had to give up caffeine due to health issues. At first it was really difficult; bad headaches, fuzzy brain. A few months later and I have adjusted.
I totally love this channel. I am an engineer and only did very basic biology, but I supplement in this channel
I have MS. Have found caffeine gum to be helpful with my neuromuscular fatigue and with mental alertness. Also found personal limits in volume and hourly frequency daily. Or some of the side-effects may present themselves. Irritability, shakey-ness, jittery, nausea, and vision issues... but prefer to other medications like modoniftll or others.
Thank you for sharing. I am looking forward to your 2nd video on how caffeine helps with duration, stamina, balance, recovery, and others.
Thank you.
I've been sober for 7-8 years now, but the coffee smell in the morning is all I need👍

it smells awful now
Could you do a video on healing? Like what defines it? Does it has different types? Does the body realize it needs to heal? And if so how? How would the body know it no longer needs to heal? Why can curtain things heal when certain things can't?
Awesome discussion made without inserts of umh, so, and you know through your presentation video, straight and forward. Thanks and good video.
Found this right as I made a cup of coffee.
I had a conversation about headaches and caffeine about an hour ago. My phone was sitting nearby, listening, so if course a video popped up. "Spy phones" 🧐🧐🧐
Thanks again, Jonathan. So deeply sharing, vastly educational … Please keep bringing it. You guys are the best.♥
This was interesting and informative. I have SVT, which is a condition where heart rate increases dramatically, e.g., 150-200bpm, not caused by exercise or exertion. I’ve gone to the ER when my heart rate wouldn’t return to normal and what did they give me? A bolus of adenosine. Actually, two because the first didn’t work. Now I know why they gave me adenosine. I’ve been drinking coffee for more than 65 years so I would say I’m not naïve regarding caffeine. I just recently became aware that black coffee (unsweetened) raises my blood sugar by 25-30 points. Don’t know the reason for that unless it’s because coffee increases adrenaline which increases blood sugar. Anyway I thoroughly enjoy these videos as I always learn something.
The adenosine you received is the med to "restart" your heart if you will. It's in the crash cart for code blues. It pretty much make you flat line, then turning the heart back on much like a computer that's frozen and you need to reboot it. But you brought an interesting point tho. I want to know the difference between the naturally occurring adenosine in the brain vs the medication. If the medication affect the brain the same way as well...probably not tho, considering it has a short half-life? And the brain adenosine doesn't come to the heart right? Otherwise, you'll die. lol
Someone please correct me if I'm wrong.
Interesting
@@lzhang92 chemically I’m certain they are the same. Adenosine affects the electrical system of the heart, and the bolus one receives to reset the heart by blocking the AV node, is way more than what you get normally get from the brain. Not being a cardiologist I can’t know for sure.
Thank you for sharing, love all your vids.
You all forget including the speaker, that we do things for pure delight and social interaction. Coffee time for us in Greece stimulates all our senses. We drink coffee in the morning, coffee with friends to chat, coffee to relax, coffee before we go out etc. Everyone is different. And Science is science.
This channel really is awesome. It's way more educational than school was, and certainly more informative than the medical fraternity here in the UK. It's a video textbook😁 Thank you!👌🏽
