Primitive men slept less than modern man. To such conclusion researchers of the University of California, USA.

Experts conducted an interesting experiment during which he went from the peoples living in South American and African tribes. On the basis of the materials collected during the expedition, the scientists came to the conclusion that primitive man slept less than modern urban dwellers. While the ancestors did not exist such problems as insomnia. Ancient people slept less than 1-3, and this is due to several factors.

Surviving to the present day Nations and tribes in Africa and South America live in almost the same way as in primitive society, although they cannot be called cavemen. After spending some time in a completely different culture, scientists realized that the tribes sleep for 5-6 hours a day, feel more energized and have no problems with insomnia.

Modern people usually sleep for 2-4 hours longer. According to researchers, the reason lies not in the number of hours and in terms of which a person falls asleep. Modern tribes, as in ancient times, prefer to sleep in a cool place, and urban residents are accustomed to lie in a warm bed, and this is one of the main causes of insomnia.

Experts remind that the optimal sleep duration of 7-8 hours, this time is enough to renew their strength. Too long or short sleep leads to a violation of biorhythms of the body.
