Sleep is your life-support system and Mother Nature’s best effort yet at immortality, says sleep scientist Matt Walker. In this deep dive into the science of slumber, Walker shares the wonderfully good things that happen when you get sleep — and the alarmingly bad things that happen when you don’t, for both your brain and body. Learn more about sleep’s impact on your learning, memory, immune system and even your genetic code — as well as some helpful tips for getting some shut-eye.

The TED Talks channel features the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes (or less).

  1. I want to hear your theories:

    If you need it colder to sleep, why do I fall asleep when I am very warm such as when the heater is on, in the hot summer, in a hot car, or cuddling next to my 3 dogs (each are about 102° F)? I struggle to sleep if it is cold (below 76°F)

  2. I've tried to find an answer to my question for s long so I thought id try YouTube comments. Why does my whole body tingle when I’m almost asleep? It's not a tingling like some body part is falling asleep due to restricted blood flow, it is more of an insanely pleasant sensation that can happen for hours or minutes while I'm almost asleep. It is honestly one of the best feelings/sensations I've ever felt. It usually happens when I sleep too much, too little or sleep and wake up at weird times.

  3. I think most people in equator would agree that even though they maintain regularity, Cooling part is probably a challenge of most of developing nations in this region

  4. What I do for rebuild my brain as I sleep for 5 hours as I don't know this brain need … If I start to sleep 7/6 hour from today may my brain become good barin ..

  5. My sleep-related superpower is somehow staying awake for another four hours despite being mentally and physically exhausted, as well as extremely tired. I have no control over this power. What's yours?

  6. 私は3、4時間の睡眠がいちばん調子が良いです。それ以上眠ると機嫌が悪くなります。ベッドに入ったら5秒で眠ってしまいます。
