1. Go to bed before 10 PM, wake up at a consistent time, and get sufficient sleep. 2. Eat meals on a regular schedule; avoid late-night meals (no food after 8 PM). 3. Get natural sunlight in the morning or during the day. 4. Move your body every hour, especially in the afternoon and evening. 5. After sunset, dim or turn off lights so the body recognizes it’s nighttime. 6. Avoid blue light from screens at least 1 hour before bed to allow normal melatonin production. 7. Relax with activities you enjoy, such as listening to calming music, using aromatherapy, or meditating. 8. Supplements can also help support better sleep.

Sleep is divided into two phases:
1. Non-rapid eye movement (NREM) sleep
This phase can be divided into 3–4 stages. The early stages involve light sleep or drowsiness. During this time, the body remains responsive to external stimuli—if awakened, you’ll wake up immediately and feel alert.
2. Rapid eye movement (REM) sleep
This is the deep sleep phase, where the body responds more slowly to outside stimuli. If awakened, you’ll feel groggy and drowsy. This stage is when the body undergoes the most repair and rejuvenation, stimulated by the **anti-aging hormone (Growth hormone)**, which is released in high amounts during this time.
Growth Hormone – The Anti-Aging Hormone
This hormone is secreted by the pituitary gland to boost immunity, support brain function, and maintain youthful vitality. The more growth hormone your body produces, the stronger and healthier you remain. A deficiency can lead to faster aging, weaker bones (risk of osteoporosis), reduced muscle mass, fatigue, premature graying, and lack of energy.
Growth hormone is released only during deep sleep, with peak production occurring between 12:00 AM and 1:30 AM.
So if you want to stay youthful, the best time to sleep is by 10:00 PM—no later than 11:30 PM—to maximize growth hormone production.
