Adolescence is a critical period of development and sleep is just as critical to that development as proper nutrition and exercise. If teenagers continue a pattern of sleep deprivation throughout their lives, they will significantly impact their overall health and well-being and put themselves at risk for serious health problems, such as heart disease, stroke, high blood pressure and depression.
In adolescence, the body’s natural circadian rhythms, or internal clock, naturally shift to delay sleepiness, causing teens to go to sleep later at night and wake up later the next morning. Lack of sleep due to this shift in sleep patterns can be exacerbated when teens drink coffee and caffeine-laden soft drinks or participate in stimulating activities, such as watching TV or surfing the Internet, too close to bedtime. Sleeping late on the weekends and taking daytime naps also can interfere with a restful night’s sleep. In some cases, the underlying cause of an adolescent’s excessive daytime sleepiness may be a sleep disorder, such as sleep apnea, narcolepsy, insomnia or restless leg syndrome.
It is important for teenagers and their parents to identify any problems early, so that they can be treated before their sleep deprivation seriously impacts their health.
