Siim Land: REM Sleep: How Much Should You Get
Peer-Reviewed Research
Key Takeaways
- Don’t obsess over REM sleep optimization – Focus on overall sleep quality, duration, and consistency instead.
- Exercise reduces REM sleep – Physical activity increases sleep pressure, delaying REM onset and decreasing total REM time.
- Depression alters REM patterns – Shorter REM latency and increased REM duration may indicate depression (antidepressants normalize this).
Notable Quotes
“More REM sleep is not necessarily better. I don’t think people should be trying to do things to optimize their REM sleep.”
Bottom Line
Prioritize foundational sleep habits (duration, consistency, exercise) rather than targeting specific REM sleep metrics.
