The researchers looked at people living in three hunter-gatherer societies in rural parts of Africa and South America. Investigations showed that these traditional peoples slept slightly less than 6.5 hours a night on average. In comparison, people in industrial societies usually average seven to eight hours per night.

The researchers looked at people living in three hunter-gatherer societies in rural parts of Africa and South America. Investigations showed that these traditional peoples slept slightly less than 6.5 hours a night on average. In comparison, people in industrial societies usually average seven to eight hours per night. "We find that contrary to much conventional wisdom, it is very likely that we do not sleep less than our distant ancestors," said the study's senior author, Jerome Siegel, a sleep researcher at the University of California, Los Angeles. However, the researchers also found that insomnia may have been more rare in ancient times than it is now. This finding suggests that looking to the past could lead to new ways of treating insomnia, which afflicts more than 20 percent of people in the United States at some point during their lives, the investigators added. People complain that modern life allows us less sleep than is natural, and earlier studies done on animals in captivity gave the researchers an idea for studying sleep in people, Siegel said. "While trying to record sleep in wild African elephants, and finding that their sleep was very different from zoo elephants, I thought that what we really needed to do was compare sleep in humans living in the regions and under the conditions in which we evolved with sleep in our society," Siegel said. [5 Things You Must Know About Sleep] To learn more about how people slept before the modern era, the researchers analyzed the sleeping habits of 94 members of three hunter-gatherer societies: the Hadza of Tanzania, the San of Namibia and the Tsimane of Bolivia. These people live much as their ancestors did for thousands of years, so the scientists reasoned that these people's sleep habits reflect prehistoric human behavior. The research proved difficult at times, Siegel said. "The challenging parts were getting stuck in water or sand in four-wheel-drive vehicles while trying to get to the villages we studied," he told Live Science. Still, "getting to know the San was a transformative experience," Siegel said. "To see how much is possible without any of the trappings of civilization. To see how smart and happy they are, and also how they must struggle to survive." After collecting 1,165 days' worth of data on these hunter-gatherers, the scientists found a surprising similarity across the three groups. Despite differences in their genetics, histories and environments, all three groups had similar sleep patterns, which the researchers suggested mirrored those of humans before the modern era. "I feel a lot less insecure about my own sleep habits after having found the trends we see here," study lead author Gandhi Yetish at the University of New Mexico said in a statement.

Instead, the hunter-gatherers began to sleep a little more than 3 hours after sunset, on average. Nighttime activities included preparing food, eating dinner, making arrows and planning for the next day, Siegel said.
