How Your Circadian Rhythm Tunes Your Health: Satchin Panda at TEDxYouth@SanDiego 2013

Learn how your biological clock or circadian rhythm tunes physiology, metabolism and brain function. Dr. Satchin Panda's research shows thousands of genes in every cell turn on and off at specific times of the day. This gene orchestra dictates the optimum times for everything from athletic performance, shaving, taking medicine to cramming for an exam.
Satchin Panda, PhD is a scientist and researcher at the Salk Institute in San Diego.

interesting talk. now I know why I can't sleep after eating chicken shawarma at 1 AM

[@Dilu777]

XD

[@theiriscen]

Yeah and its not due to the shawarma

[@isuckatdrawing4265]

Such an amazing session i just read about circadian cycle in my 11th ncert and i searched about it and found this informative session amazingly explained every student should watch this

[@essielmedina3906]

I loved this TedTalk with professor Satchin!! Such an interesting topic to watch and know during this hard time.

[@kaushal09able]

It is very nice to see your lecture on such a huge platform like TedxYouth. As a viewer, I am much more educated as a server of chronobiology.

[@tyroney2]

Very interesting. A friend of mine is an extremely competitive athlete that routinely engages in things I never would, like ultra-marathons, 100 mile bike rides, etc.-- and he told me that if I wanted to lose weight or trim up, all I really needed to do was to not eat after 7pm. And in case where there must be an exception, it could not include carbs. His advice (which I know came from his own personal experience) seems to correlate well with this video.

[@skaterdude14b]

Tyler Breeden why carbs? Why not fats, which could just as easily get stored as adipose?

[@Vanessagetthickfitv]

Because carbs actually turn into glucose and get stored as fat much quickly than fats do. The Keto diet is a main example of using fat for energy instead of carbs, Atkins is another.

[@TiMalice2009]

Vanessa precisely

[@IvanBFit]

Vanessa Incorrect. Processed or semi-processed foods turn to fat quicker, not fruits and vegetables, which are predominantly carbs.

[@paulhb]

Ivan B Youre talking about two different things. Processed foods can include fruits and vegetables. When people are talking about eating keto they need to be excluding starches and sugars, primarily. Eating broccoli and spinach is fine.The intake of protein and fat is not looked at as a negative. Some keto food can be processed. I tend to stay away from most of that.

[@MIKExMASSACREx]

He’s on to something here but honestly I believe the circadian rhythm is a sync up of your sleeping and eating patterns. So time restricted eating and proper sleeping patterns help facilitate the rest of the bodily functions

[@carrollhoagland1053]

Thanks Dr. Panda, I am a fan our yours and Dr. Longo ... 70 Going On 100

[@manasmangalpattanaik3539]

Very well descriptive and easy to understand talk. Great Dr. Panda. My friends had developed "My Circadian Clock" app.

[@Balcon200]

Great vid, thanks!

[@amarynthia8416]

Great explanation.

[@joshdat3reak]

Love this guys voice

very cool!! and interesting.. im doing my sincints progict on the circadian rhthm and it is very interesting.

[@user-zn3iy8vw9k]

excellent talk

[@manudasmd]

Very imp topic

[@alisobh7258]

thank you

[@johnbates2709]

Excellent

[@Melody429IU]

watching this at 1am for research project

[@filmpoptime8278]

interesting talk I wondered 👏

[@terrorteffa]

Awesome 👊

[@lisaphilosophy]

Yes!

[@nfactorial4074]

I can’t fall asleep with an empty stomach!!!

[@SG-ji5ij]

You're body will adjust if given time. Slowly decrease your eating window by 30 minutes a week until you finally reach the recommended eating time for your last meal, which is 6 hours before going to bed.

[@lisathorley]

Yeah Scott's right. We have a circadian rhythm not just for sleep, but for other bodily functions too (such as eating). So you can adjust your eating pattern so that you will be hungry way before bed, and not hungry near your bedtime.

[@mryan4452]

Stuff your face during the day! And stop at 7pm working your way down to 6pm over time. These 2 guys are correct.

[@hotwheelsracetimebbb3870]

Sir could you give me an answer besides gadgets whether our electric bulbs can affect circadian rhythms

[@djurovukotic7655]

alot of things are left out here. by fasting ie eating controlled and thereby automaticly fasting more during sleep woulf create a state for ketosis. shifting between ketosis fat burning and glycosis is key to proper body functions.

[@alisamsg446]

Ketosis is sooooo healing. It's very important to me to be in ketosis even though I eat carbs..

[@LillianGreenHiLilly]

TEDxYouth please can you tell me if the Watch Pat 200/300 measure and identified circadian rhythm disorder. i need to know a.a.s.p.

[@thiru7198]

nice talk

[@mkyysmaa]

The speaker mentions that force production is higher in the evening due to the (clock) genes found in the muscle tissue. Does anyone know any good references for that?

[@nooraalkaabi6947]

[@geminijake7398]

Why is Circadian Rhythm "Synced" with the cycle of the rotation of the earth? Generally speaking, we become conscious or "rise" with the suns appearance, and we hibernate with its disappearance. Is it purely from light stimulation being that the sun is out, thereby stimulating consciousness? Light photon induced consciousness.

[@SusanRodgers-fw3nf]

Interesting. Since I was a baby I go to sleep late. I have tried breaking this cycle many times. I wonder what advice he would give me?..?

[@nonrepublicrat]

People sleep better in a dark room? That's so amazing!!

[@AlmazulVortex]

He says best time to exercise is afternoon evening, and Ayurveda that goes full wuth this subject of circadian rhythm says best time is from 8 to 10 in the morning. Regards

[@hamzahassan7851]

Though the SCN is the primary body clock (or the hub), organs and tissues can act independently. For example, you decide after a night out with friends to sleep through most of the next day, because this is a one off to you, the timing of how your organs and tissues won't change. Your kidney will still remove waste from blood and balance body fluid within their natural and best times. Note how it won't rely on the SCN (because you're asleep). However, if you continue going down this road, you are re-training your kidneys by shifting the timing of when they work best (day time) to times when they should be resting. This opens the doors to many diseases. It is also why those that work nights only die younger. I'm tempted to say, although I personally do think it's in the morning because of the high energy surge, it peaks in the after afternoon. My educated guess is to see us through the day so we do not drop off completely.

[@MrApplewine]

Is he sure the clock tells us to eat in the morning when we wake up and not a few hours before we go to sleep? I especially wonder given how insulin helps melatonin production. I think organisms normally rest after eating, though many animals eat all the time, but that isn't fasting. Also, mouse and human hormones may not be the same timing.

[@lopezthinktank]

That's a great observation. I have come across videos that explain insulin resistance; the spike in glucose in your blood can cause you to feel sleepy. Perhaps the type of food in your diet is also important. Checkout Tyler Breeden's comment about no carbs after 7pm. Also, remember in Thanksgiving we eat turkey that contains Tryptophan which also causes sleepiness. Food is intended to be fuel for the body but maybe we tend to overindulge requiring our body to break down food before we can move about more comfortably. --Check out the Chinese Organ Clock.

[@CreedofAbraham]

Lmao he tripped at 'go back to cry.. Go back to sleep'

[@stopkaks]

CHYEAHHHHHHHHHH

[@Eagles.Fan.Since.Super.Bowl.52]

I can’t ignore pizza o’ clock

[@BusyB07]

Or 🍺:30

[@iwantlee9510]

Amhifb fat diet is not an unhealthy diet. You really must live undrer a rock if you still believe that today. Fat is more calorie dense than protein snd carbs, so a lesser volume of foos contains the same calories. That's all.

[@SusanRodgers-fw3nf]

By the way, I think that Dr. Panda is handsome. He has a soothing voice too. His lecture is very interesting.

[@larisajover8968]

Im feeling bad now, I just eat and its 02.00 in the morning :(

[@gabesemployee3524]

if you want to gain weight can you just eat at night and still be healthy?

[@arwenjoseph7199]

What if you always sleep with bright light on because you are afraid of the dark? What would this do to your clock?

[@lisathorley]

Well a bright indoor light is probably around 500 lux (light intensity) whereas outside light is in the 10,000's. You will still register the light change outside, and still have some kind of patterned circadian rhythm for your sleep. Also melatonin is produced during dark lighting, so your indoor bedroom light won't prevent melatonin production, but perhaps lessen or delay it. So the result would be that your circadian clock would be delayed, and you'll fall asleep later and later. But there's other factors that come into it too (e.g. Sleep propensity (sleep 'pressure'), eating habits, wake up habits, sleep hygiene (phone use in bed), exercise, stress etc.).

[@CK51515]

Face you fear and sleep in dark. Also try wearing a eyemask

[@jasonwong2851]

i WONDER WHAT WILL BE THE HEALTH EFFECT IN MUSLIM FASTING - FAST IN THE DAY AND EAT IN THE NIGHT?

[@user-yy7xf7jg9k]

No, We Eat early morning and Break Fast at the evening.

[@TheRockstarFarmer]

So don't eat at the tine of day im the most hungry. Got it.

[@justaguy4real]

So they say we have the timing of Mars. But my dog is clearly on Earth time. I swear, we could set the correct time based on his timing readiness to eat and go out.

[@marquelltyric2153]

sooo we sleep at 6 and wake up at six? im down

[@JbeastBoi]

Me who is watching this at 2 am in the morning lol

[@recalecyrk6335]

Wow you had an option. This was my school work

[@ansels2adams395]

I am trying to reverse back to daylight. I am getting to sleep at 4am anymore! Any ideas? I mean, once you have your clock backwards, how do you gradually get back to dayshift.? Any ideas. ??

[@wolphay5636]

blackout curtains and lights out. meditation

[@skaterdude14b]

ansels2 adams fast the day before, or stop eating as early as possible. Blue blocking lenses after dark ($9 amazon). Cold and heat exposure. Melatonin. Force yourself to wake up early by taking a caffeine pill and let yourself go back to bed.

[@iwnunn7999]

ansels2 adams I heard that if you force yourself to stay awake for as long as u can (several days) that will reset your inner clock

[@eyeshalfwayopeneyeshalfway2603]

Baylen Miller ...take the caffeine pill when?

[@kristenbeasley8259]

this is complicated. I work 12 hour shifts three days a week over night. 6pm-7am. the other four days I try and reset so I can be up in the daytime and then reset again for my work nights. it was easy at first. but a year later and my body has no clock it seems. chronic fatigue.

[@kichagang5983]

He is confusing in the mice research explanation and he made a mistake in that mice research concept explanation..... I reversed and checked that mice research explanation many times..... If any one find it let me know... Don't understand it the way he explained because it's wrong in between....i didnt mean that he is wrong in his concept but by mistake on the flow he explained wrong

[@isurinibaravinda4688]

Fast forward 9 years he has not aged much. May be because of the body clock eating pattern he follows

[@chextabexta4425]

We could optimize our lifestyles if only we didnt work 8 hours study 4 hours, eat, do chores, etc etc, get more sleep. hmmm seems like theres a grander systemic problem preventing us from optimizing. Which is addressed in his later video kzbin.info/www/bejne/nJTMeIF4g5Whga8

[@desertknights5003]

No . Afternoon is not the best time to hit the gym

[@ankurmanju9579]

He meant 5pm

[@LuisGarciaSprout]

This was Nobel Prize worthy!!??? It’s common sense!!

[@buknar456]

not everyone follows it though, it's becoming a really big deal...sleep science and sleep hygiene are growing topics and we're learning more all the time...for decades scienetists didn't know that much about sleep

[@yazadbhathena672]

Try reading their papers and seeing if the mechanisms behind biological clocks are still common sense.

[@marlenelara9300]

Humans have lost all common sense my friend !!! We have become the most technologically advance but dumb generation of all times ... is pathetic

[@ajmarr5671]

Biological Alarm Clock: Biological alarm clocks are biological mechanisms that tell us when to eat, when to sleep, and when to make babies. For women, oftentimes the biological clock goes awry, and begins to signal all sorts of jarring behaviors that seem at least to the man of the house to be most untimely. This biological alarm clock jolts a woman into action, or more likely, into prodding a man into actions at the wrong time. A woman's biological alarm clock is often out of sync with her husband's own biological clock, which naturally runs much slower. The man compensates by resetting his own clock to give himself more time. Unfortunately, women have no capability to reset their own clocks. This results in their ringing just in time to tell their husband to vacuum the floor as he settles back to relax from a hard day at the office, or to mow the law or bath the kid just as the big game comes on TV. All too often the wife gets all wound up just as the husband starts to unwind. Unfortunately, the only way to set back your wife's clock is with a blunt object to the head. However, this is not recommended since it would set her back in time permanently, and force you to do time, as in jail. from Dr. Mezmer’s World of Bad Psychology, found on an internet near you!

[@alisamsg446]

Hahaha... had a good laugh. Homosexuality seems more appealing now, after reading this. Two women= vacuuming at the same time. Two men= unwinding at the same time. Problem solved. Heterosexuality is not natural anymore :D

[@cult237]

I got forced to watch this

Lol same
