UC Berkeley researchers have identified the brain’s hidden circuitry that regulates growth hormone during sleep, showing how rest fuels muscle building, fat burning, and cognitive function. Their findings, published in Cell, reveal a feedback loop where sleep boosts hormone release, and the hormone in turn influences wakefulness. It’s long been known that deep, restorative sleep triggers growth hormone—essential for muscle repair, bone strength, fat metabolism, and healthy development. But scientists had not fully understood why disrupted sleep lowers growth hormone levels. By studying mice, the research team traced specific neurons in the hypothalamus that control hormone release. They found that two key players—growth hormone-releasing hormone (GHRH) neurons and somatostatin neurons—work in harmony to balance release during different sleep stages. UC Berkeley scientists uncovered brain circuits linking sleep and growth hormone. The study shows how deep sleep fuels muscle, fat burning, and cognition through a feedback loop, offering new insights into sleep, metabolism, and brain health. Brain and brain waves during sleep
