"The myth of the eight-hour sleep"

[grammarwoman]

I came across an interesting article from BBC News Magazine. It states that "[a] growing body of evidence from both science and history suggests that the eight-hour sleep may be unnatural."

According to this article, before it became cheap and easy to have light during the night, it was common for people to have "a first sleep which began about two hours after dusk, followed by waking period of one or two hours and then a second sleep."

Something to ponder for those with sleep issues...
