The system that heals the body during sleep Sleep is not simply a pause in activity — it is a period of intense biological repair. While we rest, the brain triggers the release of growth hormone, a molecule essential for cellular renewal, tissue regeneration and metabolic health. The scientific discovery; https://www.sciencealert.com/study-reveals-brain-system-that-repairs-your-body-while-you-sleep Researchers at the University of California, Berkeley, have for the first time directly recorded brain activity during several sleep–wake cycles in mice. They found that: growth hormone is released differently in slow-wave and REM sleep; the balance is regulated through the locus coeruleus, a brain region linked to wakefulness; sleep and growth hormone form a dynamic feedback loop: lack of sleep lowers growth hormone, while excess growth hormone can stimulate wakefulness. This discovery could help develop treatments for sleep-related disorders, type 2 diabetes, Alz...
