I’m in bed early now. When I was a lot younger I could go to bed at any time and feel good in the morning. Not now though lol
too much dopamine. reduce that and find your sleep get better.
I feel like shit every morning. Maybe I'm dying
I'm forced to work midnights at my job. 11pm-8am 5 days a week. I need to get outta there.
I did it for just over a year thinking "This is the best/easiest money I have ever made". Just know that this schedule will fuck you up in the long term. I will never do it again ever & strongly advise anyone against it.

“Why we sleep”-great book
Nope. It's the worst book on sleep ever written.
@@doncryptonium5160 how come?
Because he dosen’t want to accept facts and research
@@doncryptonium5160 explain
Lex is clearly trying to rationalize the fact that he has shitty sleep hygiene. Built up tolerance for caffeine and energy drinks can't be good in the long term, either.
What he’s saying is, if you get a benefit from something that causes u to miss sleep, does that matter? To some degree yes it has to. But maybe not to the extent he thinks
I can relate to being self employed and when creativity hits your mind, you need to act on it. Its for the greater good overall in thee long run
neither is a life half lived and half-spent sleeping, sleep is overrated. everyone is different though I guess
@@jasonpatio8338 j
sleep hygiene, wow what a douchey phrase
Thanks Never knew that. I will start sleeping from today
The reason you can fall asleep so easy Lex is because YOU"RE SLEEP DEPRIVED
if you can sleep whenever you want, even after drinking stimulants, is because you are living "tired". Your body is always yearning some sleep. You are living under your potential.
When I was a teen caffeine gave me a nice jolt and it didn't interfere with sleep. As I got older caffeine started to interfere with sleep. Maybe it's a case where your tolerance goes down with exposure and Lex hasn't hit that level yet.
@@WeighedWilsonCaffeine always interfere with your sleep, it's likely that you don't realize it when you're young. When I was in my teenage years a slight sip of coffee would make me stay wide awake in the night. Lex was probably not realizing this too.
@@WilliamParkerer Not always. Drink about 14hours before sleep with a fast, all good. Half life is exceptionally controlled by factors beyond any study you’ll quickly look up on google. In a fasted state, black coffee, staying somewhat hydrated, a meal 3-5 hours later. You will likely not be affected to any meaningful extebt.
This guy is 51. I trust his opinion.
That's why khabib put Gaethje to sleep - A kind human 🙏
thats really weak
Interesting , lately I've started to remember my dreams but only the nightmarish ones .
The irony of the fact I’m up early hours watching videos on how important sleep is……
Watching this at 3 in the morning.
In typical conditions, @41yo, I'm out for 6 hrs. Almost right at 6 every time no matter what. I must have a strong internal clock. 20 yrs ago I could easily sleep for 10 hrs, and I was way less active than I am now, interestingly enough.
Lex, I agree, ruminating on the ideal number of hours sleep one should achieve is incredibly stress inducing for me also.
Sleep is the best 💟
Less sleep means I am using up my lived hours while my body is younger. If I sleep twice as much and live that much again as long in my twilight years, what have I gained but sunsets and back pills?
I think it’s more about the energy and sharpness that you can achieve if you sleep in a healthy manner. Specially if you are doing sports or physical activities, the recovery it’s so much better. 👍🏼
Not many memories of playing with grandkids come before middle age.
Man I’m eating a Spicy Chicken Sandwich from Popeyes right now 😂😂😂
Spicy chicken sandwiches from Popeyes is the key to longevity.
@@rookie90210 nonsense
doubtful, unless u meant I just ATE because no one pauses mid eating a popeyes chicken sandwich to mention they are eating it... NO ONE!
@@bobspurloc 😜🤣👍
I'm totally Lex on this clip
When I switched to Healthy Keto+IF/OMAD, I started to sleep max 5h, usually 4h and I felt totally fine, actually well-rested.
Before I slept as long as 14h, with an usual length of 10h a night and never felt rested. Not even on 8h.
First 4 years of Healthy Keto+IF/OMAD I took no naps. Now, I take a 10-20min nap 2-4 times a week.
But: each and every time I ate more of healthy carbs, when I went over 50g healthy carbs, I slept longer that night and maybe the next.
No carbs, or under 20g(for me)=5h well rested sleep.
You sleep less because your cortisol levels have risen, unless you have a genetic predisposition towards sleeping less you can't cheat sleep, carbohydrates making you sleepy is suggestive of poor insulin sensitivity.
no studies link sleep and prevention of cancer?
Watching this while lifting weights at 1am
Can someone catch up on sleep? I've read where the body automatically does it, but how much does the body build up? How much until you reach equilibrium?
read "why we sleep" or watch this podcast: czcams.com/video/pwaWilO_Pig/video.html
catching up on sleep is not possible
To some degree yes you can. Try it
@@nofurtherwest3474 Matthew Walker (We can't catch up on sleep. Sleep is not like the bank. You can't accumulate a debt and then hope to pay it off at a later point in time. I should also note the reason that it's so catastrophic and that our health deteriorates so quickly, first, it's because human beings are the only species that deliberately deprive themselves of sleep for no apparent reason.
Matthew Paul Walker is an English scientist and professor of neuroscience and psychology at the University of California, Berkeley.[2] He is a public intellectual focused on the subject of sleep.[3]
@@victorsanner541 it’s not exactly like the bank. But you can catch up. If you pull and all night we one night then sleep in the next then you’ll make up for some of it.
And it’s not that detrimental if done sparingly. Lots of people pull all nighters in college and go on just fine later in life. Its nominal
@@nofurtherwest3474 literally everything you just said is wrong, educate yourself, read some books written by smarter men. Don't make statements based on personal anecdotes. Really, read the book, it is fascinating
I got Narcolepsy bro I can get as much sleep as I want, my hypocretin are gone, which means it's rare that I'm rarely ever "awake". People think narcolepsy means you just randomly sleep. It's more like... The majority of your time is spent ready to fall into REM, whether your awake or asleep.
I would check for Narcolepsy if you're falling asleep and going directly int REM sleep, that is a marker .
Also, anything weird happen when you laugh?
The diagnostic test for narcolepsy is simply:
- can fall asleep in under 5 mins, in a sleep study, many times in 1 day
Type 1 Narcolepsy means you have Cataplexy (when you laugh/strong emotion, you lose muscle tone)
Type 2 Narcolepsy is without Cataplexy.
The common signs for all narcolepsy is:
- constant sleepiness
- sleep paralysis
- hallucinations (before/after wake)
-sleep attacks (unable to stay awake)
- sleep disruption
But I would just ask yourself: is your rem sleep overactive? Do you go into REM in your 20 mins naps.
That's a solid way to think about it. Somehow I get the feeling you have it, just from seeing you talk about your sleep but maybe I'm projecting haha
But I tried fixing my diet too bro, my habits, all the self help bull, sometimes your brain is just different and you gotta work with it not against ha
@@fishbrainLTD thank you for the breakdown. This makes me think about my own sleeping issues.
is your bed or pillow really hard? Im asking cause I just figured out mine are and are the reason I havent felt rested in years.
So is this guy saying that it’s bad to sleep 8 hours in the day as opposed to 8 hours at night? I always thought it was the amount and depth of sleep not the time you sleep
Agree with almost everything Lex says here.
Diablo 3 is dope though I stayed up a lot of nights to play it bro! You know how hard it is to unlock season rewards? I didn't ask for this, just my destiny I guess
4-6 hours is all I can get. My body naturally will wake and then I start thinking of things to get done, so I’m up let go!!!
He said I would guess 😂
when I was single I would often go to bed like 2-3am. Now that I'm married with kids I'm in bed by ten
My cats breath smells like cat food
Sounds like she puts out even after marriage. Lucky guy.
Ten?! You night owl. Since having kids I’m dead by 9pm
Would you guys say you sleep better now going to sleep early or or worse?
@@tomjwjss better
without Accident,cancer and Corona
Pardon me before seeing the video want to say what emerged in MIND just now and during sleep everything must be and should be active but our EGOS becomes either ZERO or helpless and advantageous of that are known to all of us. Thanks for such titles beyond artificial INTELLIGENCE.
☑️✅
I stayed awake for 48 hours bro
lol lady in Japan, sleeps 4-5 hours, runs about 15 miles per day, she is over 110 she started this at 65 because her husband called her fat, no other mention of the husband in the short video
Das why I be sleep.
Sorry, I am sleep.
I would say 5 hours minimum and 8 hours max of sleep is good.
well that was worthless
no one should be restricting their maximum. sleep till you wake up by yourself
I sleep 23 hours every day and look like a teen in my thirties
That's not enough sleep.
@@NoBody-tk3yd do you use NZT?
@@Trevco I'll start.
Meanwhile David is thinking this dude is finna die 20 years before me.
Thank the gods, I don’t want to be around for much longer anyway.
How old are you lex my brother is my 1st question
33/34 I think.....
Watching this at 2:31AM here in India FML
Our organism knows best what is good for it .
We just have to listen what it says to us .
I'm going to enjoy life with the Family happiness gives you longevity. Working 40 hours a week for the state doesn't make me happy for sure just paying there taxes so they can sit and dictate our outcomes.
sleep gang in this bitch
Does he looks to you like 51? Im 35 and I look older I tell you
Well, I'm screwed. Thank you America for creating this soul sucking existential dread inside me. I can now die young and waste literally every second I have going to school full time and working full time and having a family full time. Also literally not being able to go home and piss for two seconds in between school and work.. I genuinely appreciate this opportunity i was forced into. Thank you. Welp gotta go not sleep cause I have a whole fucking house to clean.. Lex, looking sharp as always!
How tf can I know if my 7-8 hour sleep is ‘quality’ sleep or not?
Most smart watches have a pretty decent tracking function built into them.
@Lèx Clips° jeeze give it a rest
Get on of those sleep rings he talked about... but I dont think he said what that ring is called
@@trevr1969 It is called an Oura ring and is about $300. It’s not perfect but gives you an idea from day to day. (I got one a month ago and am happy with it) Apple Watch is also Ok but not quite as good as the ring. Still, though the oura ring isn’t nearly as good as getting a sleep study. But as a daily tracker I still think the oura ring is worth it because you can compare your sleep trends over time, which is accurate enough for me.
@@MissTEO1 nice... thank you
Kids make alot is what I've learned
LEX I WOULD APPRECIATE IT IF YOU HAD MICK WEST ON YOUR SHOW< THE NEWEST UFO VIDEOS HAVE BEEN DEBUNKED to a point where we can rule out alien tech
Tell that to Sam Harris who has been approached by intelligence agencies to help disperse new phase of uFo data to be released, more compelling data. Mick west is painting himself into a corner.
Apparently for David, botox is also essential for looking like longevity.
Savage. First time in a while I felt bad after laughing!
How do u know he had Botox?
He has great skin!,
@@nofurtherwest3474 So, look at his eyebrows and forehead when he speaks compared to Lex. Lex creates lines on his forwards as his eyebrows move.
David on the other hand, his eye brows don't move at all. Essentially this is what botox does in order to maintain a firm and smooth appearance on your forehead.
@@NoBody-tk3yd So you don't actually know, it's just an assumption
Longevity is not really the best metric for maximizing life utility. If you spend the majority of your years eating lettuce and sleeping , you haven’t really lived at all.
You need to multiply each event by how much excitement , adrenaline , and factor in your particular ability in the moment.
A man hitting a golf ball 250 yards is not the same experience as one hitting it 300. Banging a hot woman trumps banging an ugly one. Eating sushi trumps eating lettuce.
Longevity is a meaningless metric. It’s about overall utility gained based on your particular makeup
And abilities that reflect maximum life lived.
Imagine dying at 40 after eating bacon and chesse burger thrice a day
Read the invisible rainbow.
Lucky we are not rats then, right? Ive traveled to many land masses in this world, and from my own experience, the most robust, vital humans who are considered to be 'old', sleep very little.
Lex it’s wrong, just organize your day good enough so you can sleep… he just keep ignoring this podcast and a couple of other episodes about sleep 😅
The problem with this host is he takes a veeeery long time to get to a simple point that it gets pretty boring. Im always looking forward to having his guest to finally speak.
Then I'm going to live forever...can sleep all day
In other news, food, water and oxygen are also essential for a long life
Sleep is essential for those that can afford or have enough resources to make it a priority. For those who can't its a luxury.
You sleep less you die quicker so I'd say you should be making that a priority.
Sleep is a luxury to those that haven't made decisions that would disallow them the time to rest.
So on one hand guy ongle left praises why sleep is important and it’s positive effects on anti aging and better health and life quality and then the host talks about his passion and that is more important than sleeping (quoting : you should have more love in your life for things you wanna do) obviously confusing and the host is clearly not listening to his guest ..
Thanks for wasting my time !!!
No definitely not subscribing
lmao you play diablo 3?? man i still play diablo 2 from time to time haha... i might start playing Diablo 4 when it comes out.. just dont know what character im gonna use
They see their lifes like they are machines or something. For what? Some lines of code more? Searching for "happiness" (funny american philosophy)? I tend to spend my days more like my dog. Short fun, long sleep. Thats it.
what a waste of your human potential. you think that’s a good way to live?
@@cryosteam3944 I dont know. It is a very difficult question. I dont think we are better off because of person X. We are only telling ourself a story. Thats all.
6 min of Lex giving his uninformed opinion while David Sinclair is waiting to talk.
Yo7 cannot hide from the fact that atleast 7 hours of DEEP sleep is minimum requirement for an over whelming majority every single night. No amount of "power napping" or sleeping on the weekend will make up for this. Stop fiddling with yourself americanos.
First 😂😂
Bravo. I really do mean that.
Woops guess ill sleep when im dead....
That poor rat
if u "RESTRICT" sleep in a rat. that is not the same as a rat learning to limit its own sleep. they are 2 different things. one is extremely stressful to the subject the other is not. STRESS is the thing causing the harm not lack of sleep.
Can you explain this more what is the difference?
@@tomjwjss if you choose to go to sleep 5 minutes later every few nights depending on how you feel extending the 2 days to weeks or months. to an eventual comfortable stop point is that stressful? no. what if I kept u awake nightly increasing 5min every night no matter what... that is stress. the amount of sleep a person "needs" is what they have learned throughout their life. it has nothing to do with what another person needs. so a blanket statements of johnny needs 8 hours so susan needs 8 too. and if susan doesnt get the same amount of sleep that johnny does. it 100% does not mean johnny is healthier. it only means one person sleeps longer than the other. sleep deprivation is how you get a rat to not sleep which is high stress. and therefore the statement is invalid.
@@bobspurloc thanks for the explanation so what would you say. The right awnser is for sleep then?
Following an answer from an science expert with "yes, but [insert some anecdotal experience and some ramblings about passion and love] works best for me".
This used the be channel I would go to run away from random baseless opinions. Sigh.
Would you prefer Lex have conversations with our soon-to-be AI overlord and get matter-of-fact, logical, emotionless responses? Ask a human, get a human answer (opinion always included).
Maybe let the person that actually studies the subject have the final word?
If he already has his mind made up, why even bother asking?
It's quite disrespectful to the guest IMO.
Why bring in such respected scientists just to preach his opinion to them?
@@EdsonMedina I feel like Lex always does a good job at trying to play the devils advocate in order to bring out more angles of information on a given subject. As if he likes asking basic questions because he knows much of his audience may have what could be deemed as a "silly question" but can't actually ask it themselves. He preaches about providing an open-minded arena for discourse and tries not to have a strictly logic-driven sense of wonder. He seems to be smart enough to know that you can't base EVERYTHING on logical reasoning in this life.
Lex does have a tendency to ignore science when it doesn’t suit his ethic!
Lex all of your guests are worth listening....but never invite Sadhguru to your podcast...some podcasts have invited him....but never invite him to your podcast...it will depreciate the value of it....I believe you haven't even heard of him...and that will be better...good luck man..
That lex guy is soooo boring just listening to him makes me want to fall asleep 😂 he sounds so dull
Lex needs iodine tablets as he is so low energy that I fear for this hipster , selfie taking boy.
