Sleep & Longevity

📋 Simple Summary

Sleep is when your body does its most important repair work. While you sleep, your brain cleans out waste that builds up during the day. Your cells fix damaged DNA. Your immune system resets. Hormones that control growth and repair are released. People who sleep well live longer, get sick less often, and think more clearly. Sleep is not wasted time. It is the foundation that everything else — diet, exercise, supplements — is built on.
