๐ง UC Berkeley Found the Brain Circuit That Ties Deep Sleep to Growth Hormone โ and It Goes Both Ways
Researchers at UC Berkeley mapped the neural circuitry linking deep sleep to growth hormone release and discovered it's a two-way feedback loop: sleep boosts growth hormone, and that hormone in turn helps regulate wakefulness. Published in Cell, the study explains why poor sleep disrupts muscle repair, fat metabolism, and brain health. Scientists say the finding could point toward new therapies for sleep disorders and diseases like Alzheimer's and Parkinson's. How much sleep debt do you think you've racked up over the years?
