Sleep serves as a crucial mechanism for recharging the body, significantly lowering cortisol levels that negatively impact the immune system. Adults should aim for at least 7 hours of sleep each night to reap its restorative benefits. The quality of sleep varies throughout the night, with specific stages contributing to essential functions like the release of growth hormone, often referred to as the "fountain of youth." Prioritizing both the quantity and quality of sleep is vital for overall health and well-being.
