Health lies in healthy circadian habits | Satchin Panda | TEDxBeaconStreet

Every organ and even every cell in our body has circadian or 24 h clock. Circadian clocks turn on and off thousands of genes at the right time of the day or night.


  1. 9:15 you can some good examples of people who doesn't have good circadian clock. Luckily they made the fist good step by attending this conference

  2. I started doing this a week ago and went from previously waking up in the night between 1am and 3am regularly to sleeping right through the night, from day 1 of restricted eating (between 7am and 7pm). I have slept right through every night and had a really deep, sleep. Try it, it works!!

  3. My circadian clock is literally upside down. I fall asleep at 6:00 am to 9:00 am and wake up anywhere from 1:00 pm to 6:00 pm

  4. I worked overnight shift(11pm-7am) for a year and a half. It was not uncommon for me to go 24-36 hrs with no sleep and then sleep for 3-5 hours and do it again. I was under severe stress. And then 5 months in I got white coating on my tongue which was Candida taking over because the gut is connected to you circadian clock. Shortly after that I got depression where I thought about suicide(never thought about actually taking my life but I thought how great it would be if a car would just hit me and get it over with). First 3 weeks after quitting the overnight shift I felt like a zombie during the day. It took me a few months to fully get use to being awake in the daytime and sleeping during the might again. I honestly don’t know how in the world there are people who work overnight shift for 10 plus years.

  5. amazing and evidence-based! I would like to learn on circadian rhythms of our organs as well, and how we can adjust the time of taking supplements

  6. I would gladly eat only in 10-11 hours timespan most of the week, but I start work at 9:30am and I exercise twice a week between 7-8pm and 10pm. I keep hearing that you need to eat after a workout, so I am kind stuck here 🙁
    (yes I know you're going to say "just exercise during the day" but I can't, it's classes I take and I can only go AFTER work, since I work full time.)

  7. The one thing at confuses me the most of Satchin Pandas work is what takes priority – light or eating window? What if my eating window is 8 hours but doesn't end until midnight? 2am?

  8. Sorry to say, but the thing with keeping circadian rhythm after closing someone in apartment just isn't true. There was some experiments with closing people in caves without time clues – lengths of phases of their days have changed.
    But great talk anyway!
