It is commonly believed that human beings need eight hours sleep per night to function and perform well.
However, scientific findings have revealed that some people are genetically predisposed to thrive on much less sleep. They are known as ‘elite sleepers’ or ‘natural short sleepers’, and studies have shown they are more likely to be healthier and more resilient than the average person.
They may be the key to unlocking sleep efficiency for all of us, and help prevent brain diseases, such as Alzheimer’s.
Ok sleep is when we process waste. I think people who can (consistently) sleep less are better at processing waste while awake. That’s my hypothesis.
Yet older people, who are presumably less efficient, require less sleep. Weird.
