  • Sleep Stages: Sleep consists of NREM (stages 1-3) and REM (dreaming) stages. Stage 3 is deep, restorative sleep, while REM aids in memory processing.
  • Cycles: A typical night has 4 to 5 cycles, and it is normal to wake briefly between them.
  • Recommended Duration: While adults need 7–9 hours, infants require 12–16 hours, and children/teens require 8–12 hours.
  • Sleep Hygiene Tips:
    • Consistency: Go to bed and wake up at the same time daily.
    • Environment: Keep the bedroom dark, quiet, and cool.
    • Diet/Habits: Avoid caffeine and large meals close to bedtime.
    • Electronics: Avoid screens for at least an hour before bed.
