  美国研究人员对与我们祖先生活方式相似的非洲和南美洲社会居民的睡眠习惯进行了调查研究。研究表明我们祖先的睡眠时间可能少于我们。以下是 Rebecca Morelle 的报道。

  From artificial lights to late-night TV and now our smartphones, modern life is often blamed for ruining our sleep. But this study suggests our ancestors didn‘t get any more sleep than we do.

  The researchers monitored traditional societies in Namibia, Tanzania and Bolivia, where people live like ancient hunter-gatherers once did. They found they slept on average six and a half hours 天龙八部 a night.

  Surprisingly, natural light didn‘t have as big an influence as was thought. Most people fell asleep hours after sunset. However, temperature was important. The morning’s coldest point was when most people woke up.

  Insomnia was also extremely rare.
