Notes

Activity

  • Activity benefits the body, mood, focus and social life. Teens need about 60 minutes or more of moderate to vigorous activity daily, plus muscle- and bone-strengthening at least 3 days a week.
  • FITT: frequency, intensity, time, type. Increase gradually.
  • Stay safe with a warm-up, cool-down, proper gear, water and rest. Stop for sharp pain. Use RICE for minor sprains.

Sleep

  • Teens need about 8 to 10 hours per night. Not enough sleep hurts memory, mood, focus and the immune system.
  • Healthy sleep habits include a steady schedule, screen-free wind-down time, avoiding caffeine late and a dark, quiet room.
