Do people really need to sleep?
Some people think that we rest during our sleep, and that without sleeping we would be tired, and get sick.
In contrast, experiments with dogs as well as polyphasic sleepers have shown that it is not sleep that we need, but REM dreams. Dogs have died when prevented from dreaming, but not when prevented from sleeping. Polyphasic sleepers get by fine with 3 hours a day of mostly dream sleep.
However, there is a guy in vietnam who has been without any sleep for 30 years! He is active and in good health. Is he lucky genetically? Or is it something he learned? This means that not sleeping does not necessarily lead to death or bad health. We just need to figure out how to get rid of sleeping.
