What Is Segmented Sleep and It Healthy?

Segmented sleep is a sleep pattern in which sleep is divided into multiple periods throughout the night. This pattern was common among our ancestors, who would typically sleep in two or more shifts during the night, with a period of wakefulness in between.

In modern times, segmented sleep is less common, but it is still practiced by some people, particularly in certain cultures. Some people find that segmented sleep helps them to feel more rested and refreshed during the day, while others find that it can lead to insomnia and other sleep problems.

There is some scientific evidence to support the benefits of segmented sleep. For example, one study found that people who slept in two shifts had lower levels of the stress hormone cortisol in their saliva, which is a sign of reduced stress. Another study found that people who slept in two shifts were less likely to experience obesity and type 2 diabetes.

However, there is also some evidence to suggest that segmented sleep can be harmful. For example, one study found that people who slept in two shifts were more likely to have accidents and injuries. Another study found that people who slept in two shifts were more likely to experience depression and anxiety.

Overall, the evidence on the health effects of segmented sleep is mixed. More research is needed to determine whether segmented sleep is a healthy or unhealthy sleep pattern.

Here are some tips for getting a good night's sleep, whether you choose to sleep in one shift or two:

* Go to bed and wake up at the same time each day, even on weekends.

* Create a relaxing bedtime routine to help you wind down before sleep.

* Avoid caffeine and alcohol in the hours leading up to bedtime.

* Make sure your bedroom is dark, quiet, and cool.

* Use blackout curtains or blinds to block out light.

* Avoid using electronic devices in bed.

* If you can't fall asleep after 20 minutes, get out of bed and do something relaxing until you feel tired.

* Talk to your doctor if you have chronic insomnia.
