As one of the three pillars of a healthy lifestyle the other two being diet and exercise , the amount of sleep you get can dramatically improve or hinder your quality of life in various ways. 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. Wright Jr. He says another reason could be that many sleep disorders increase with age. Inadequate sleep negatively affects health in a number of ways, says the American Academy of Sleep Medicine.

Sleep deprivation can really do a number on your mood and performance. It can make you feel irritable, anxious, or depressed. It can make it difficult to concentrate on everyday tasks.

Lack of sleep can become a safety hazard when it results in drowsy driving and workplace injuries, says the sleep organization.

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

Winter recommends trying to build in a little bit more consistency and not having such a wide span of sleep timing.

He also recommends going to bed and waking up around the same time every day. 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.

In our current culture, someone who falls asleep immediately is viewed as a good sleeper. The reason? People who can fall asleep quickly at any time and anywhere may have narcolepsy, a chronic sleep disorder characterized by excessive daytime sleepiness and sudden sleep attacks. 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. In recent years, there's been a push to bring doctors up to speed on the potential health risks of sleep disorders, and so now more people with sleep disorders are being properly diagnosed and treated, says Wright.
