Sleep Facts

  • 40% of Americans over 60 and 20% of Americans under 60 have trouble sleeping.
  • Medical problems, poor lifestyle habits, and/or stress cause sleep problems.
  • Sleep problems do not go away without treatment.
  • The average person needs 6 1/2 to 9 hours of sleep per night. Exact amounts vary from person to person.
  • You do NOT need less sleep as you age.
  • You cannot learn to function normally with 1-2 fewer hours of sleep per night than you need.
  • During sleep, the immune system is restored; physical growth, and tissue repair occurs; and learning ability improves.
  • Your brain does not rest during sleep. There are five stages of sleep:
    • stage 1 & 2 are light sleep
    • stage 3 & 4 are deep sleep
    • stage 5 is the dream stage or REM sleep (REM- rapid eye movement).REM sleep is essential for physical and mental health.
  • Without REM sleep, anxiety, irritability, and erratic behavior increase and your learning ability and immune system are impaired.
  • To improve REM sleep, do things that tap into your creativity.
  • Snoring is not healthy and may indicate the presence of sleep apnea, a life-threatening sleep disorder.
  • The sleep/wake cycle:
    • the setting sun signals the body to settle down, relax, and repair; darkness triggers the release of sleep hormone, melatonin, and neurochemical, seratonin
    • we fall asleep according to the drop in our body temperature and sleep best when our body temperature is at the lowest point.
