Why Sleep Matters 

Friendly Reminder: it's 3AM

Lecture begins at 7:53

*Them explaining* Me at 3:am watching this:"I agree"

2 years on doing night duty knocked me. Took me two years to get back my normal sleep patterns. Now sleep 9 wonderful hours a night. Bliss

I noticed every time my sleep is disturbed, my hypertension goes crazy, in spite of my meds, and my temper gets a lot worse. When I get enough sleep, my mood is a lot better and blood pressure is normal.

Watching this at 4am, after being asleep since 4pm the day before, but still feel i can use another 12 hours of snooze time lol

For some people the really deep stages of sleep come early in the morning. Hence the really good deep sleep up until noon. I like that he said getting too much sleep is a myth.

I was scared to sleep most of my life due to problems around me...and then much more problems due to other things caused insomnia..how terrible damage now am nearly healed and so glad and want to help others

I am a physician & sleep 8& 30 min / day , No discounts , this is my body needs everyday , am 33 year & i look & feel 20

Anyone else watching this when they should be sleeping? 🙄

When I was a kid, I didn't like sleeping at all and just liked to stay up all day playing. But all of that has changed since I was about 14 15 years old. Since then, I have realized that sleep is very important, if I don't get enough sleep, I will not be able to stay awake to do anything, and I will always be tired. Now I love sleeping but because of work, I rarely get a good night's sleep

The tips are great. Also, try having a routine the last 30 minutes before going to sleep such as putting the phone down, turning off the computer and getting some water. Your routine can vary, but doing this every day will let your mind and body know it's time to fall asleep. It also helps to listen to some soothing music *HINT* *HINT* *WINK* WINK*.

I fell asleep to this lecture about how important sleep is at 1:00am last night. What irony and coincidence

One of my dreams when I was in Uganda was to study at great universities like Harvard. Thanks for sharing such crucial info here. I can't agree more that sleep is very important to me. My body reacts if I don't get enough sleep.

Wondering late at night, coming across this talk.. honest to god.. the irony of how it lets me sleep in 15 minutes.. This is my go-to video before I want to sleep.

This is such a calming lecture

That’s why Daylight Saving Time must end as people’s sleep patterns are interrupted twice a year because of a law passed by the politicians.

Can't believe I'm watching this at 3:18AM , been binge-watching inspirational/educational videos all day...and night

I just had this conversation with my therapist today. As the second speaker said, I am fat, stupid, sick and unhappy. Literally. I was thinking about suicide last night, like many other nights. And my therapist quoted Jeff the Killer when he ended our session, he said, "Go to sleep." It's 2:40 am... and I am feeling sicker and lonelier than ever. So I just organized my time and I will do my best to go to sleep at 11 to wake up at 6. I just hope it's not too late.

I always recommend 8 hours a day. Thanks for the video!

Loved the lady saying to start school later. YESSSS!!! I absolutely KNOW i would have done better in school if I'd had adequate sleep, but I had to work to help my family survive. I worked the swing shift all the way thru high school, getting home about midnight or 1:00 a.m. If I could have just slept in in the morning, it would have helped SO much. I might even have managed to graduate 🎓 😅

Next time anyone feels sleepy behind the wheel, if you can't pull over to sleep in your car, try singing along with something on the radio. Has kept me awake every time.

I sleeeep way too much. Now a study was done saying that I’m statistically destined to live a shorter life now. 🤦‍♀️ I guess balance is everything.

Me at 5AM doing class notes: “mhmm, very interesting”

Excellent speakers and fascinating info about the power of napping! I nap after lunch every day for about 30-45 mins and derive huge benefit from it. I often do my best academic work after a siesta...! Also, a problem in the morning seems to seem a lot less after a nap in the early afternoon.

Watching this while trying to fall asleep at 5am. I’ve learned nothing, apparently, and I have to cook the mac and cheese for thanksgiving 😩😩 #HappyHolidays

Daylight savings MUST END

i’m watching this at 3am. nice

Excellent. Thank you. "It - the body - is like a horse which carries the personality and spirit, and as such should be well cared for so it can do its work! You should certainly safeguard your nerves, and force yourself to take time, and not only for prayer and meditation, but for real rest and relaxation...." ~ Lights of Guidance, Baha'i Faith

Sleep makes you a safer driver. A study in the United States revealed that drivers aged 16 to 24 were “nearly twice as likely to be drowsy at the time of their crash” when compared with drivers aged 40 to 59.

5mg during the day for relaxation and it completely removes my anxiety. Then 10 to 20mg before bed with a ashwagandha. Now that is the best sleep I’ve ever had. Wow

2021: Economies of Scales: “Siestas” ruled Europe lunch-hour, Banks/shops all closed until re-open or not to 5-7pm. Vacations for one whole month/July-to-August. Business(9-2pm)reopen@4-7. In USA, 12Hrs. Between shifts. People could afford to leave job & walk home @midday to eat with their family and take a NAP...(Siesta); No cars; bus. Kids return to late sessions of classes, too.

Before my sleep study, woke up 60+ times per hour (AHI 61.0), with a cpap, I may wake up 3 times per hour, huge difference in sleep, energy, not to mention weightloss efforts.

BRILLIANT! Thank you so much, Harvard Professors. 🙂 We appreciate your passion for your work!

Okay, I’m playing this entire lecture. I mean to be more sound about sleep and this really helps me achieve that goal. Thanks Harvard.

I literally have two exams today and I got 6:30 sleep listening to this despite taking melatonin.

Even when I sleep well for a week straight and go just one night without it, I'm totally exhausted and depressed the entire next day.

Very ENJOYABLE and EXCELLENT Program. It is obvious to me this panel is very sound and scholarly. I will apply their information and share with ALL my contacts, this important information and my contribution for others to benefit. 👏👏👏👏👏👏👏👍😍

49:10 world needs such honest professors

In order to sleep, it has to be fun to sleep. So, if we are being creative in making things fun by using the theory of suggestion, a talk with the divine, massage various parts of the bodies while breathing deeply, drinking water to lower the temperature, etc.., then sleeping would be easy. In short, the body has to be cool, and we have to breathe deeply to bring more oxygen the cells, then we would just sleep. If it still does not work, then try to massage every parts of the body while breathing deeply, so the muscles could be relaxed. We have to tell ourselves that we would deal with things the next day, and if it is beyond our control, then let God do the worry while we sleep.)

Very nice and broad explanation about sleep. Yes a person who gets sound sleep can perform his best in the morning and during the day and I have experienced that if you don't get enough sleep at night, in the morning you feel you can't do some of the things that you usually do like driving.one day to make up for the lost sleep I slept for one hour in the morning and took tonics and after some time I felt I could drive with confidence.

I really love topics about sleep it has always fascinated me yet I always sleep late at 12:30 or 1

Who else searching video to help sleep and ended up sleeping to this talk 😂

Being a lifelong napper I have perked up to listen to any intelligent info about that. I'm encouraged to hear that naps are helpful with cognitive&memory issues. Don't remember the specialty but no doubt naps do not supply opportunity for some critical functions that cannot be caught up on with more sleep any time soon. Interesting topic. Enjoyed muchly.

32 years of Insomnia Sufferer here. I am a Insomniac. Not by choice here. I absolutely hate it. I always pray for sleep I have never not slept because of thinking on things . Or worrying about things. No. Absolutely Honest to God. I don't do that. I just don't. Sleep. Or rarely get sleep. Sleep is literally everything. It's vital. Our lives depend on it.

That first gentleman was very knowledgeable about this. So was the second gentleman. Okay all of them. Thank you Harvard.

Excellent lecture. Thank you.

On a certain level, we have sleep in our brain, the neurochemicals that show up in flow: so dopamine, norepinephrine, anandamide, endorphins, and serotonin. If you were to try to cocktail the street drug version of that, right, you're trying to blend like heroin and speed and coke and acid and weed- and point is, you can't do it. It turns out the brain can cocktail all of 'em at once, which is why people will prefer flow to almost any experience on Earth. It's our favorite experience. It's the most addictive experience on Earth. Why? 'Cause it cocktails five or six of the largest pleasure drugs the brain can produce. We're all capable of so much more than we know. That is a commonality across the board. And one of the big reasons is we're all hardwired for flow, and flow is a massive amplification of what's possible for ourselves.

A wonderful lecture! Quality sleep is so vital for good health.

The great resignation is an opportunity to balance workplace environments. It’s never pointed to and wasn’t covered in this lecture, but workplaces can be toxic and contribute to sleep issues. Lean philosophy imo has been a major contributor to workplace stress. Covid has given people time to think. And they may get it right by negotiation for better employer employee relations.

Thank you from iraq Harvard is a great un. I dreaming in studying in it 😢

perfect to listen to while i fall asleep thanks!

Okay let me just say that the last answer at the end by the doctor in the middle was brilliant.

Despite the frustrating beginning, I got a lot out of this, especially in the latter half. Thank you.

Best medicine for insomnia. Put on ANY Kevin Costner movie. Sit comfortably or lie in bed. They are so slow and lengthy and boring you will be snoozing in no time at all. My favourite is “ Message in a Bottle” It takes you to REM sleep in a flash. You won’t even be aware of all the long Tyrsome facial close ups of Kevin. Or even the lengthy periods without dialogue. @Waterworld runs a close second.

Listening to this and can't help but wonder if that's part of the mechanism of why it's so easy too forget how terrible the first few months of being a new parent are?

The adrenaline surge of constantly being awakened every 3 hours 15 minutes to urgently refuel helicopters, I'm never going to sleep right again. The best times of my life!

Me listening to this on my way home from work at 3 am 👁👄👁

medical school : Sleep is very important The moment you graduate : You need to do night shifts and work 24 h without sleep

Whoever watching this, I wish you good health.

Suggestion that a key part of the need for sleep is the body's need to make serotonin, which it does in a symbiotic relationship with gut bacteria in the large intestine. We sleep to first produce serotonin, then to draw it into the body through the extraction of water in the large intestine. Though it can be synthesized, there seems to be a major difference in the health benefits from the micro made serotonin, and the artificially made serotonin. Here's some notes on both how important serotonin is and how widespread it is in all living things. Besides mammals, serotonin is found in all bilateral animals including worms and insects,[19] as well as in fungi and in plants.[20] Serotonin's presence in insect venoms and plant spines serves to cause pain, which is a side-effect of serotonin injection.[21][22] Serotonin is produced by pathogenic amoebae, and its effect in the human gut is diarrhea.[23] Its widespread presence in many seeds and fruits may serve to stimulate the digestive tract into expelling the seeds.[24] Gut bacteria manufacture about 95 percent of the body's supply of serotonin, which influences both mood and GI activity.

I saw this title in my sidebar as I just finished coming off the cuff of pulling an all nighter for no good reason whatsoever

Watching the whole video at 3 AM, this will help.

Having enough sleep is having a longer years of stay on this earth.

I'm watching this at 3:00 a.m. and I have narcolepsy. Oops

One night I was in a McDonald's fairly late to get some schoolwork done and a whole bunch of families were hanging out after church. The kids were tired, but the parents wouldn't leave. My kids had been in bed for an hour by this point. I felt really sorry for those kids bc I had no idea when they'd get to sleep after eating McDonald's late at night.

Wow! The flu shot response blew me away

The acgme and every residency in the countrt should watch this. Revamp the medical education system so that we residents can get more sleep!!

I've suffered from chronic insomnia for 25 years. I now suffer from hypertension and obesity (despite a very small appetite. I never feel hungry).

Everyone knows why sleep “matters”. Insomniacs hate being reminded .

Thank you doctor Stickgold. I saw you on CNN and threw away my alarm clock. Nobody ever woke me up since! I bet I owe you some extra smarts I got! :)

It's been 10 mins in video and I am going to sleep to watch it tommorrow morning 💐

No joke, this certainly was the last seminar for now 😂😂😂😂😂😂

Watching from Bangkok, Thailand.

Tremendous opportunity to learn more about sleeping..

Watching now.. As 1st Year Nursing student from Pakistan 🇵🇰❤️😍

why are they not viral ?? cat chasing cucumber gets 10000000000000000 views

Hello! I am from Uzbekistan. Thank you very much✨😍⭐

Very helpful information. Thank you for posting this video.

Thank you RU-vid for recommending this at 2:30am when I'm about to start working

Schools should start at 9:00 am for our children and teens. Or 8:40 -8:45

Don't think tonight I'll be able to complete watching this video without falling asleep...

Thanks for your excellent lectures.

I am using this lecture as a lullaby to sleep

What a great class!❤️

Starts at 8 minutes mark.

Thanks for telling me this information it really helps my body claim down and no.it is not moving a muscle thank you very much

Thanks, Yes I agree that adequate sleep is Crucial for the brain and body, to repair itself! Also for good performance, each day! Insufficient sleep, Causes the brain to malfunction. It impairs function!

I am 65 and have been living in Spain for just over a year now. I am curious as to why the speakers have not touched on the subject of siestas. Have they conducted any research on the pros and cons of effectively having twice as many days in a year. Albeit half days. Most animals nap at random times during the day so surely this must be hugely beneficial to humans as well.

This guy must need some water he was talking for basically 2 hours without drinking water 😭 imagine he was doing a talk about how you should stay hydrated lmao 😂

This was brilliant. Loved it. Thank you so much

My Gosh, the modern world of electronics with one click away! A lot of us, including myself, should be sleeping stead of watching, well, after all life is hardly be serious at 2:45AM. :))

Wow this video worked so well, puts me to sleep everytime I watch it. 😅

fact that I’m watching it in middle of night when I actually should be sleeping 😳

Insomnia is a real eye opener....

i fell asleep while watching this 6 hours before i had to drive to school in the morning

How does this critical information get less than 1000 likes?🤔🤔🤔

It's ironic how this video is riddled with tired jokes in the comment section about watching while sleep deprived.

This was great!! Thank you

Thank you, it`s a very great job 😻 This video is so beautiful💜💜💜
