Scientists discover sleep switch that builds muscle, burns fat, and boosts brainpower

Deep sleep does far more than rest the body — it activates a powerful brain-driven system that controls growth hormone, fueling muscle and bone strength, metabolism, and even mental performance. Scientists have now mapped the neural circuits behind t…

Stroke triggers a hidden brain change that looks like rejuvenation
