What’s Segmented Sleep?
Nobody questions the importance of getting enough sleep. At minimum, it’s essential for rejuvenating the mind and revitalizing the body. But, what is enough? And what does it look like? Many people find they wake during the night and wonder if they’re suffering from a sleep disorder or other health issue. While that could be totally possible, it’s also possible that sleep may not be an all-night thing. In fact, historical records, centuries-old literature, and ancient references to sleep are all revealing a whole new way we should be looking at how we slumber.
Segmented Sleep: More Normal Than You Realize
If waking up during the night is a frequent “problem” for you, you might wonder if you’re suffering from insomnia or sleep apnea. “Segmented sleep” is a seemingly irregular sleep pattern that may not be a disorder at all, but a natural biological response that we, in modern times, have forgotten.
English scholar Roger Ekirch cemented the idea that our ancestors used to naturally “practice” segmented sleep, using their middle-of-the-night waking hours to pray, meditate, or finish chores around the home. [1] Roger Ekirch found references to “first sleep” and “second sleep” in literature, legal documents, and even letters written before the Industrial Revolution. The in-between hour or hours were usually spent in prayer, and many find it to be one of the most relaxing periods. This may be because this middle period between first sleep and second sleep is around midnight where the brain produces prolactin, a hormone that supports a feeling of relaxation.
