Should you stay in REM sleep most of the night?

It is not recommended to stay in REM sleep for the majority of the night. While REM sleep is an essential stage of the sleep cycle, it typically makes up only about 20-25% of total sleep time. The other stages of sleep, including non-REM sleep stages such as deep sleep (also known as slow-wave sleep), are also crucial for overall health and well-being.

Staying in REM sleep for an extended period can disrupt the natural sleep cycle and potentially lead to sleep disorders, daytime sleepiness, and impaired cognitive function. To ensure optimal health, it is important to have a balanced sleep cycle that includes adequate amounts of all stages of sleep.
