Scientists discover the deep sleep circuit that impacts muscle, fat, the brain
2 days ago
- Scientists discovered the brain circuit linking deep sleep to growth hormone release, revealing a feedback loop.
- Growth hormone during deep sleep helps build muscle, burn fat, and support brain function.
- The circuit involves GHRH and somatostatin neurons in the hypothalamus and the locus coeruleus in the brainstem.
- Poor sleep disrupts growth hormone balance, increasing risks for obesity, diabetes, and neurodegenerative diseases.
- The feedback loop ensures balance: sleep drives hormone release, and excess hormone promotes wakefulness.
