  • Infants (4-11 months): Sleep range widened two hours to 12-15 hours (previously it was 14-15)
  • Toddlers (1-2 years): Sleep range extended by one hour to 11-14 hours (previously it was 12-14)
  • Preschoolers (3-5): Sleep range extended by one hour to 10-13 hours (previously it was 11-13)
  • School-age children (6-13): Sleep range widened by one hour to 9-11 hours (previously it was 10-11)
  • Teenagers (14-17): Sleep range extended by one hour to 8-10 hours (previously it was 8.5-9.5)

According to Dr. Lawrence J. Epstein from a 2007 published book Harvard Medical School Guide to a Good Night’s Sleep which discussed strategies to achieve adequate sleep. He recommends a variety of measures to help adults and children produce sufficient sleep. In general, all of these approaches are designed to assist with relaxation as the desired sleep time approaches, to sustain a comfortable sleep environment, and to foster a healthful balance of nutrition and exercise.

Their recommendations include the following:

    • Maintaining a regular sleep-wake schedule
    • To avoid too much caffeine, alcohol, nicotine, and other chemicals that interfere with sleep
    • To make your bedroom a comfortable sleep atmosphere
    • Setting a calming pre-sleep routine
    • Sleep when you’re exhausted
    • Avoid watching the clock at night
    • Utilizing light to your advantage by exposing yourself to light during the day and limiting light exposure in the evening
    • Avoid taking a nap too close to your regular bedtime
    • Eating and drinking plenty—but not too much or too soon before bedtime
    • Exercising daily—but not too soon before bedtime

In America, 70% of adults report that they obtained poor sleep at least one night a month, and 11% say poor sleep every night. Each day, millions of Americans experience daytime sleepiness and exhaustion resulting from sleep disorders. Sleep plays a role in good health and well-being throughout our lives. How much sleep you need to stay healthy, alert, and active varies, depending on our age. Most adults require at least seven or more hours of sleep every night. If you are suffering from frequent wakings in the middle of the night, having a hard time falling asleep, or waking up feeling like you never slept at all, you may need to see a physician to look into the benefits of a treatment plan.
