In today’s episode, Matt challenges the notion that REM sleep is solely for the brain, revealing its broad impact on physical health. He delves into REM's role in regulating testosterone and growth hormone, crucial for muscle function. Our host also highlights how REM aids muscle recovery via paralysis, boosting blood flow and supporting protein synthesis.
Beyond muscles, Matt explores REM's effects on temperature regulation and heart health by boosting heart rate variability and promoting stress resilience. He also uncovers REM's surprising links to reproductive and immune health, from genital blood flow to enhanced immune cell production. Matt emphasizes that prioritizing REM sleep is vital for whole-body well-being, and that, by embracing the full spectrum of REM's benefits, we can all unlock a potent pathway to not just a rested mind, but a thriving, resilient body.
