Research shows that teens need at least 8.5 hours of sleep a night, which most teens do not reach nightly. During adolescence, the body’s circadian rhythm (like an internal biological clock) is reset, telling teenagers to fall asleep later at night and wake up later in the morning. This change in the circadian rhythm happens because a teen’s brain makes the hormone melatonin later at night than the brains of kids and adults do. However, your teen may also be suffering from insomnia, which is most commonly caused by stress. While everyone has trouble falling asleep from time to time, if your teen regularly cannot fall asleep and stay asleep, they may have chronic insomnia.
Common causes of chronic insomnia could be other medical conditions, mental-health problems, side effects of medicines, or even substance abuse. If you think your teen may be suffering from chronic insomnia, you can get help from a doctor, counselor, or therapist. However, before seeking professional help, you could attempt reducing the stress your teen feels and make sure they have a comfortable sleeping environment, as these are the usual causes of insomnia.
