The amount of sleep a person needs each day varies with age, according to the National Sleep Foundation.

Pregnancy, sleep deprivation, and poor sleep quality can also affect how much sleep you need, according to the Mayo Clinic. Children, and especially adolescents, who often keep late hours during the school week, are particularly vulnerable. According to research presented at the American Academy of Pediatrics national conference, fewer than half of all 6- to year-olds are getting 9 hours of sleep on most nights.

Older adults need about that same amount of slumber as other adults, but they tend to sleep more lightly and for shorter time spans than younger adults.

Research suggests those who suffer from this sleep disorder are more likely to experience irregular heartbeats, heart failure, heart attacks, and strokes.

Sleep Education recommends limiting exposure to bright light in the evening, turning off electronic devices at least 30 minutes before bedtime, not eating a large meal before bedtime, avoiding consuming caffeine or alcohol before bedtime, and reducing your fluid intake before bedtime.

That said, people who consistently have difficulty falling asleep may have insomnia. This, among other reasons, is why many sleep disorders go unrecognized and untreated in clinical practice. Historically, doctors didn't get much training on recognizing sleep disorders.
