Functions of Good Sleep Part 1
🧠 1. Memory and Learning Consolidation
During deep sleep (NREM) and REM sleep, the brain consolidates what was learned during the day and clears accumulated “neuronal waste.”
🧬 2. Cellular Repair and Regeneration
During sleep, especially in deep phases, the release of growth hormone (GH) is activated, which is vital for repairing tissues, muscles, bones, and skin.
🩸 3. Immune System Regulation
Sleeping well boosts immune activity. Sleep-deprived individuals have a higher risk of infections and a weaker response to vaccines.
❤️ 4. Cardiovascular Health
During sleep, heart rate and blood pressure decrease, which protects the heart. Poor sleep increases the risk of hypertension and heart attacks.
🍔 5. Appetite and Metabolism Regulation
Poor sleep deregulates the hormones ghrelin (hunger) and leptin (satiety), increasing the risk of obesity, cravings, and insulin resistance.
