Scientists from the University of California say that an adult needs no more than 6 hours of sleep a day.. Scientists conducted a study that involved three groups of hunter-gatherers from three countries - Bolivia, Tanzania and Namibia.

These peoples live without the benefits of civilization, just like our ancestors many millennia ago.

As a result of the study, scientists found that most of the volunteers slept for 6 hours a day and at the same time their health condition is much better than that of the inhabitants of most developed countries..

Also, the inhabitants of the above nationalities very rarely recorded such a sleep disorder as insomnia..

According to the researchers, the absence of disturbances in the sleep process is associated with temperature, because the volunteers woke up during the cold time of the day, and in our homes the temperature in most cases is constant, this contributes to a longer sleep duration..
