Sleep and Biological Age โ Why Good Sleep Is Anti-Aging
Sleep is when the body repairs and resets. Chronic shortage or irregularity speeds metabolic, immune and brain aging.
How to lower your bio age
- Keep a consistent sleep and wake time
- Dim screens and bright light an hour before bed
- Avoid caffeine late in the day
- Keep the bedroom dark and cool
Why it matters
Repair
Deep sleep drives cell repair and waste clearance.
Metabolism and hormones
Short sleep disrupts appetite and blood-sugar hormones, speeding metabolic aging.
Brain
Sleep supports memory consolidation and brain waste clearance.
Regularity
Erratic timing lowers recovery even if total hours look fine.
