Natural Sleep is In Two Segments: Why Tahajjud Prayers is Normal? The Most Blissful Time

Posted by

Businessinsider.com: Roger Ekrich noticed many old books, including Chaucer’s “The Canterbury Tales“, referenced two periods of sleep being the norm in their era.

Via Dreamland: Adventures in the Strange Science of Sleep:

…Ekirch somehow rediscovered a fact of life that was once as common as eating breakfast. Every night, people fell asleep not long after the sun went down and stayed that way until sometime after midnight. This was the first sleep that kept popping up in the old tales. Once a person woke up, he or she would stay that way for an hour or so before going back to sleep until morning—the so-called second sleep. The time between the two bouts of sleep was a natural and expected part of the night and, depending on your needs, was spent praying, reading, contemplating your dreams, urinating, or having sex. The last one was perhaps the most popular.

So researchers did a study. When subjects had no exposure to artifical light they reverted to this 2 stage type of sleeping:

Soon, the subjects began to stir a little after midnight, lie awake in bed for an hour or so, and then fall back asleep again. It was the same sort of segmented sleep that Ekirch found in the historical records. While sequestered from artificial light, subjects were shedding the sleep habits they had formed over a lifetime.
