What is the sleep cycle?
The sleep cycle is a pattern that our bodies go through while we sleep, consisting of several stages that repeat throughout the night.
How many stages are there in the sleep cycle?
There are typically five stages in the sleep cycle: stages 1, 2, 3, 4, and REM (rapid eye movement) sleep.
What happens in each stage of the sleep cycle?
During stage 1 and 2, you drift into a light sleep. Stages 3 and 4 are deep sleep stages where the body repairs and regenerates. REM sleep is where most dreaming occurs.
How long is a complete sleep cycle?
A complete sleep cycle typically lasts about 90 minutes and repeats throughout the night.
What can disrupt the sleep cycle?
Factors such as stress, poor sleep habits, and certain medical conditions can disrupt the sleep cycle, leading to sleep disturbances.
