Sleep discovery reveals how rest builds muscle, burns fat
NewsNation • • health
Key Points:
- Researchers at UC Berkeley have identified a brain circuit in the hypothalamus that links deep sleep to the release of growth hormone, which is essential for muscle building and fat burning.
- The study, published in Cell, shows that two brain chemicals regulate growth hormone release differently during sleep stages, with one promoting and the other inhibiting its release.
- During deep non-REM sleep, the inhibitory chemical decreases while the release chemical slightly increases, triggering a surge in growth hormone that also influences sleep-wake cycles.
- This discovery could lead to new treatments for sleep disorders associated with obesity, diabetes, and heart disease by targeting the brain circuit controlling growth hormone.
- Understanding this mechanism may also advance research into neurodegenerative diseases like Alzheimer’s and Parkinson’s, as the circuit impacts brain regions involved in alertness and cognition.
