Unexpected discovery of the sleeping time of the ancient people

Many people believe that modern people sleep less than the ancient people because of the appearance of light bulbs and phones along with technological devices. But is this true?

New research on the sleep time of the ancient people

A study conducted with primitive tribes shows that our sleep time is similar to the sleep time of tribal habits that closely resemble ancient tribes.

Research by a group of scientists from the University of California, USA, led by Jeremy Siegel, has made unexpected conclusions.

Jeremy Siegel said that many people believe that the sleep of the ancients lasted from dark to morning, while modern people would sleep less than 2, 3 hours due to the influence of electric lights. Many doctors also recommend that people should sleep every night for 8 to 9 hours but he always suspects this, doubting whether this is true?

Jeremy Siegel and his colleagues studied three primitive tribes from Bolivia of the Americas, Tanzania and Namibia of Africa. These tribes are still in the process of sustaining life by hunting and picking vegetables. Therefore, they can be considered as the group with the closest life to the ancient people. Researchers have installed electronic devices to be able to monitor every state in their daily lives.

Reports indicate that although these primitive tribes lived far away from each other, they had many similarities in sleep. From the start of the bed to the time of waking up, they slept between 6.9 and 8.5 hours per night, the actual sleep time ranged from 5.7 to 7.1 hours. The sleep time of modern people is the same. According to a US survey, the sleep time of many people ranges from 6.5 to 7.5 hours.

This shows that the sleep of the ancient people is not the same as saying "Sleep as soon as the Sun goes down and works when the Sun rises"?

According to the study, the ancients may not go to bed immediately, but they still have activity after the Sun sets between 2.5 and 4.4 hours, then goes to sleep. In the morning, they often wake up before dawn, only the tribe from Namibia continues to sleep an extra hour after the Sun rises because it is very cold early in the summer.

Research shows that the most influential thing about primitive sleep time is not the light that people often think, but the variation of temperature . After the Sun is out of sight, they will wait for a low temperature to a certain extent to go to sleep. They will sleep more than an hour when winter comes.

Of course, some people will not recognize the results of this study. They argue that the primitive tribe's sleep time is not much does not mean that modern people do not need to sleep so much because modern people face a great deal of life pressure. In any case, these primitive people have a point of admiring modern people, it is a deep sleep . In their world does not seem to appear from the word "insomnia".
