- Dr. Samer Hattar and Dr. Andrew Huberman discuss why Daylight Saving Time is bad for health, both due to the shifting on to and off of Daylight Saving, but also due to the later shifting of the day brought by Daylight Saving Time.
Dr. Samer Hattar is the Chief of the Section on Light and Circadian Rhythms at the National Institute of Mental Health. Dr. Hattar is a world-renowned expert on how viewing light at particular times adjusts our mood, ability to learn, stress and hormone levels, appetite, and mental health. Dr. Andrew Huberman is a neuroscientist and tenured professor in the Department of Neurobiology at Stanford University School of Medicine.

“The reason they do it is because they don’t understand the biology.” That hits the nail on the head with this and many other irrational public policies.
This is why our worker coop abolished this. When day light saving times starts, we change our times in the other direction to compensate against it.
Your employer changes the nominal work hours to effectively keep the same solar time schedule? That's brilliant. Way to effectively nullify DST!
This is awesome, power to the people,thanks for sharing!
Honestly what's what I often wish to do...
Make standard time the STANDARD 💯
My body is sooo effected by it, im so tired early and all evening, in bed by my usual 10 but cant sleep till one or two in the morning, i usually fall asleep in minutes. It happens every year and takes me weeks to get adjusted.
just simply adjust the clock manually and ignore the DST
if there are schedules just subtract 1 hour
that's what I simply
I wanted them to get rid of DST, not make it permanent!
Precisely. And this explains the reason you feel that way.
Some states are actually hopefully opting out of DST this year (2024). Oregon and Idaho already have bills that have advanced all the way past the state senate with the final vote on Tues. 2/20. The absence of DST in the spring and summer months would be a non-issue. Who cares if sunrise would become 4:15 - 4:30am? No one is forcing you to get up that early. With DST, the clock time is "later" but work starts at the same time. So, if you wake up at 7am, you are really waking up at 6am on DST.
6am standard is the same time as 7am DST.
Permanent standard time > changing the clocks twice a year > Permanent DST.
I couldn't agree more with Dr. Hatter. We should only be on Standard Time, always!! That would be the day when when we abolish Daylight Savings Time. I'll campaign for it. I think the problem is is the way we change back to standard time. They blame the shorter days on Standard Time when they are naturally getting shorter anyways.
What I'd tell people who say "oh, you're just a morning person who doesn't want me to have evening light" is that they're getting up an hour earlier anyway with daylight savings time, so they're not getting extra daylight, they're just being tricked into waking up an hour earlier and thinking they get extra evening light. Night owls should love year round standard time, it doesn't force you to get up earlier and if you really want that extra hour, just wake up an hour earlier. I'm a morning person who gets up at times like 3:30 AM to 5 AM and is asleep by 10 PM most nights, my boyfriend is a night owl who goes to bed well after midnight, we both agree, abolish DST and enact year round standard time.
It seems to me that the issue is less what the clock says and more how demanding employers and schools are about when people are expected to show up and be functional. The second factor is whether you are a lark or night owl. One size start times just doesn’t fit human beings. Personally I hate, in the Northeast, how it gets dark at 3:45 pm and look forward to it staying lighter until 4:45 pm. However, I set my own schedule and don’t set 8 am meetings. The person who said it above has it exactly right: with rigid work starting times and school schedules, this dramatically cuts into people’s sleep. And less sleep means more problems of all sorts, accidents, disease, poor performance. With one set time all year round however, combined with flexible start times culturally, things could get better. But that’s unlikely to happen. Little children who tend to wake earlier start school later than teens who need more morning sleep. It would be great to put “sleep” and “flexible start times” on the agenda along with a DST.
My sleep was perfect until the last time change and has been jacked up ever since. Really grinds my gears
It's terrible, it makes me sick.😩
Yeah this disruption is horrible for society and we should have never engaged it!!
Right it was just for the world war and daylight tings old shii!
I'd be interested to know the stats on productivity in Arizona. This data could be used for change.
Hope this gets a lot more attention
As a hyper active narcoleptic (honestly)....It takes 2 to 3 weeks for me to adjust to the time change. Brutal.
Andrew, do you know what steps can be taken to PREVENT the further passage of the new bill into permanent Daylight Savings Time? I am totally against DST and would like it abolished. Any suggestions or recommendations for us individually or as a collective voice?
Call your US House Representative. Get your family, friends, coworkers...every person you know to call and let their voice be heard! Down with Daylight Saving Time!
Seems like a really nonsensical argument. Keeping it consistent makes sense, but there should be no difference between staying on daylight saving time and staying off daylight saving time. In both cases you’re not switching. In both cases you’re allowing for the symmetry. The argument just makes no sense.
If standard time is better for our health, why do I always feel so depressed when we switch back to standard time in the Fall? When it’s dark at 5 pm, I want to curl up in a ball and cry 😢
I hate standard time. Day light saving time has shown us the benefits of an extra hour of day light in the evening is so much better.
Maybe you have autumn depression, it has nothing to do with standard time. Standard time is just adjusting your clock to the sun. If the sun is in the middle of the sky it should be 12 o clock, not 13 o clock.
Finally someone explains this properly. I'm not doing daylight savings anymore.
I agree with you but I’m not opting into joblessness.
Saludos !Dr Andrew gracias por compartir muy buena información!
Fascinating
Yeah saw that bill passed this morning. Why are they not even caring about the science AT ALL? Ignorance and complacency in this ignorance baffles me. And if the US pass this, Canada will have to follow and our winters will become unbearable. 🤦♀️🙄😵💫
This is supporting what the bill wants.
@@triciafrank8582 it's the opposite. The bill is to keep DST year round. These guys are advocates for standard time year round. As am I
Fast forward to 4:55
why unbearable
@@Poetry4Peace we barely see the sun in the winter already but that would mean us not seeing light in the morning at all (if the sun comes up at 8:30-9 and goes down around 4-4:30 we are at the office) - same goes for kids in school. Seasonal depression is real and that would not help at all.
@@Cinerouquine yeah soo true.. and what was the bill
It's so much more healthier to have SOLAR NOON as close to 12:00 as possible.
Why isn't this gentleman going to each and every US Senator and Congressman and explaining it to them? My seven year old understands how bad DST is. Why can't these so-called adults?!
In the northern hemisphere, solar noon is also earliest in November and latest in February, accentuating DST’s delirious effects, causing it to vary by almost an hour and a half!
In the last 15 years or so since the time change was moved up to March, it feels 10x harder to get used to DST, than it was when it was in April.
I hope eventually the US moves to permanent standard time. Moving the sunrise times in June from 4:30am ST to 5:30am DST does not make the extremely early sunrise times any later. 5:30am on DST feels like 4:30am on standard time because they are exactly the same time of day, just the hour is inflated by 1. Same thing with sunsets. 8:30pm on DST is the same as 7:30pm ST. I'd rather sleep in until the regular time in June, instead of waking up one hour early.
People make such a big deal out of it. But if you are able to sleep in one hour on weekends on DST, you can do standard all year.
For us who live further norht it's really beneficial i'd say. Otherwise the sun goes down at around 10 pm at that really fucks with your sleep (sometimes I go to sleep and it's bright as day outside). And the sun goes up like 4 am so whats the point of that even.
If I recall correctly most countries implemented it during some world war to increase productivity (longer working days). But for us who live in the north it's really nice to have the sun rise a little earlier in the winter and set a little earler in the summer.
Nobody likes when it's pitch black until 9 am.
Fun fact: Japan stopped observing Daylight Saving Time in September 1951 after the war efforts. Nobody complains about sunrise and sunset being too early at 4:24am and 7:01pm, respectively.
In the United States, sunsets in nearly all locations would be later than 7:01pm by 30 minutes to an hour.
If Japan hasn't changed the clocks forward in over 70 years, the US can do the same.
DST is a mirage, fooling the brain into thinking it is later than it actually is.
Instead of springing forward to Daylight Saving in March, it would be better to just keep standard time all year, with summer hours starting earlier and ending earlier as an option, to mimic DST for those who want the "extra Daylight" later in the day, without changing the clocks. The morning people can just wake up earlier, while the rest of us can just sleep in one hour later beyond sunrise.
Daylight savings never bothered me. Going forward or backwards.
I hate the switching back and forth. But I love daylight saving time verses standard. I feel like im going insane throughout winter.
Its easier to get up after a full nights sleep even in the dark but its harder to keep going at the end of the day when you're tired and its dark.
with that being said, it also doesn't need to stay light out until like 11 pm, which it very much does in northern latitudes. I'm Canadian and DST has ALWAYS messed me up big time.
@K.C-2049 This is why it just doesn't work to do it everywhere. Here the latest it's light out is 9:30 and not for very long.
At my longitude solar noon is at 1245pm during standard time and 145pm during DLS. It messes with Circadian Rhythms no wonder everyone sick. If I didn’t know better you would think this is being done on purpose.
Standard time is normal time most closely aligned with the sun. Daylight Saving Time is manipulated time. It is abnormal. It is so unhealthy mentally, emotionally, physically. By deliberately changing time, we affect future events. We cause increased car accidents, heart attacks, strokes, suicides, depression. Events like the recent bridge incident in Baltimore literally would not have happened if we never changed the clocks for Daylight Saving Time. DST literally caused this tragic event. Who knows what events would occur if we left the clocks alone, but at least we wouldn’t have had a hand in meddling with them. We change fate by changing time. But man is blind and ignorant. He simply can’t do what is right, but continually does evil.
Think about shift workers!
I’m confused. Are they saying the we should keep it like we have in the summer time or keep it like we have in the winter time?
Thinking winter time. But for where I live they want to stay on day light savings this year. Passed through the senate.
Whoops from my research the US wants to remain on Day light only Arizona and Hawaii are committed to Standard time
Monday mornings are bad too - don't buy a car made that day -
Looks like Daytime Saving Time = Nighttime Spilling Time.
So it appears that we are more likely to make Daylight Savings Time permanent.
That's an improvement, but how bad is it compared to _no_ DST?
Proof that government CARES NOT for the people!
Unfortunately, here in Colorado they intend to stop on day light savings for financial reasons, tourism. Does anyone know if it passed and is the entire US stopping flipping the clocks but remaining on Day light savings forever this year? Do we have to move to Arizona? 😂😂
I'd be interested to know the stats on productivity in Arizona. This data could be used for change.
I will happily lose an hour of sleep for more daylight in the evening. When you have young kids life feels so bleak when it’s dark at 5 pm. I just moved the California recently, and I had no idea how much shorter the days were on the west coast. In Texas we could take our kids to the park and play outside for another hour after dinner. I know California politicians are pushing for for year-round standard time, but I think my soul will die and wither away. Year-round DST sounds perfect - 6pm sunsets for winter/7 pm sunsets for summer. Can’t we all just sleep in a little longer? Would that be so terrible?
Then why don’t we stay on standard time and you just wake up an hour earlier and plan your day accordingly?
People have complained for 100 years, but no one is listening in the democratic countries it seems.
Now think about people working in the night shift. Damn...
Einstein's definition of insanity is trying the same thing more than once expecting a different outcome. All year round DST had been done more than once with major tragedies. Dark mornings are horrible and waiting till 9am to get your day started waiting for daylight is absurdity. I need my morning light and my health.
slackers love DST
I just hate it when it’s dark, black night at 5 pm. I wanna be outside playing with my kids - not cooped up inside with them begging for screen time for the last few hours of the day. I’m a morning person, and would happily do year-round DST. I love waking up when it’s still dark outside. Definitely depends on where you live tho. I think sunset is too early on the west coast winters. I’m so much happier during DST in California. I’m guessing it’s probably better for the economy for businesses to have an extra hour of daylight during business hours.
Daylight saving time may be bad for your health, but I think if you made it, or standard time, (which is what most people would prefer) permanent, it would be just as bad, if not worse.
Where I live, this is what things are like now.

I don't know about the evenings, but 4:58 is too early for sunrise, imo.
I say stick to changing our clocks, even if it's a hassle. It's the only way to get the right amount of daylight in the mornings all year round. The only part of the world that shouldn't have to worry about that is everywhere closest to the equator.
DST permanently would be ideal
They do it because they do understand the effect on the body. They're weeding out the weak.
Sam Hattar has no facts in arguing DST is bad for our health. Its the time change that is harmful not staying on a specific time frame like ST or DST. There is no scientific evidence one is better than the other. Daylight saving time has shown us that an extra hour of day light in the evening is very beneficial to activity's rather than the extra hour of day light while most of us are sleeping or getting ready for work. That hour of day light in the morning is basically wasted.
What a load of rubbish.
