  Understanding Sleep and Its Impact on Health 😴🌙 Sleep is not just rest—it’s a vital process that affects every part of our health. Good sleep helps the body repair, refresh, and prepare for the next day. 1. Boosts Immune System 🛡️ During sleep, the body produces infection-fighting cells and proteins. Poor sleep weakens immunity. 2. Improves Brain Performance 🧠 Quality sleep enhances memory, learning, and decision-making skills. 3.
