Why Sleep is Vital for Health

The Functions of Sleep

Sleep isn’t just downtime; it’s an active process where your body and mind recover.

• Physical Repair: During deep sleep, your body repairs tissues, muscles, and bones.
• Memory Consolidation: The brain processes and stores information from the day.
• Immune Support: Sleep strengthens the immune system, helping to fight infections.

The Science of Sleep: Understanding Sleep Cycles

Sleep consists of multiple stages, each serving a specific purpose:

• Stage 1: Light Sleep
  • The transition phase where the body starts to relax.
• Stage 2: Deeper Relaxation
  • Heart rate slows, and body temperature drops.
• Stage 3: Deep Sleep
  • Critical for physical recovery and immune function.
• REM Sleep
  • The stage where dreaming occurs and the brain consolidates memories.

Each cycle lasts about 90 minutes, and 4–6 cycles per night are ideal for restorative sleep.
