Time to Go to Bed

The time people go to bed varies across cultures and from person to person. Some people think they do their most creative work late at night. Others like to get to bed early so they can wake up early and get to work. Compare the sleep patterns of a college student and a farmer and you’ll see almost opposite schedules. But according to a recent article in the Wall Street Journal, sleep patterns didn’t used to be so different.

Before coffee shops and electricity, people slept in two segments, or parts. They first went to sleep after the sun went down. Then they woke up around midnight and stayed up for about an hour before going back to sleep for a second time. This was true in different cultures.

However, these sleep patterns shifted with the invention of the light bulb. Coffee houses, factories, and other places could stay open all night. And with the development of the computer, sleep patterns have shifted even more. It’s not uncommon for people to stay up all night working on the computer, playing games, or using social media. In fact, the glow of a computer screen is as common as sunlight for some people. They might even see the computer screen more than they see the sun.

Researchers have found that in cultures that don’t use electricity, people still sleep in two segments at night. In a recent study, the same sleep pattern appeared. In the study, people had electricity taken away from them. After time, they too slept in two segments at night. Our sleep patterns may be different now. However, without electricity, they look very similar.
