This week, Matt dismantles the myth that REM sleep only benefits the mind by revealing its profound importance for physical health. While deep sleep handles some repair, Matt details how REM is crucial for peak testosterone and growth hormone release, vital for muscle, bone, libido, tissue repair, and metabolism. He explains that REM's characteristic muscle paralysis (atonia) isn't just for safety; it fosters physical recovery by enabling deep muscle relaxation, boosting blood flow, lowering cortisol, and regulating inflammatory cytokines.

Matt further explores how REM resets the body's thermostat, enhances cardiovascular health through heart rate variability, and improves lung function via unique breathing patterns. This vital stage also supports genital tissue health, significantly ramps up protein synthesis for muscle repair, and strengthens the immune system by promoting essential cells and cytokines. Matt concludes that protecting REM sleep is non-negotiable, as it serves as a cornerstone for both mental and essential physical restoration and function.
