There is no universal recipe for everyone. It's like shoe size. It is important to choose an individual schedule and conduct a personal experiment.

Professor Clifford Saper, from Harvard, said: “The brain of a sleep-deprived person works normally, but from time to time it happens something similar to a power failure in an electrical device.” During this failure, the area responsible for fear is activated in the brain. Then it begins to work as if the person is in danger. This is manifested by muscle tension, wet palms and unstable emotional state.

The most important problem is that such a person can stop noticing a decrease in productivity, there is a false sense of security. This could have serious consequences. That is why you should not drive if you do not sleep well.

There is another way of looking at this problem. For example, professor of psychiatry Daniel Kripke, who has devoted his research to sleep problems, says that excessive sleep is also very harmful to the body. People who sleep between 6.5 and 7.5 hours a night live longer. They are more productive and happy. And excessive sleep can even be harmful to health. You may feel worse sleeping 8.5 hours than sleeping 5 hours.
