The Science of Sleep: Why 7-9 Hours Matters

Sleep is not just rest - it is when your body performs critical maintenance tasks. During deep sleep, your body repairs tissues, strengthens the immune system, and consolidates memories. Adults who sleep less than 6 hours are at higher risk for heart disease, diabetes, and obesity. Tips: Keep a consistent sleep schedule, create a cool dark quiet sleeping environment, avoid screens 30 min before bed, limit caffeine after 2 PM.
