Summarize this article in one sentence.
Biological changes make teens and adolescents susceptible to the following sleep disorders  Snoring and obstructive sleep apnea: caused by illness or allergies that enlarge adenoids and tonsils. GERD: gastroesophageal reflux disease.  Restless leg syndrome: Restless leg syndrome: a movement disorder, causing involuntary movement, preventing REM sleep. Parasomnias: the most common are insomnia, somnambulism (sleep walking), and night terrors. Bedwetting: Symptomatic of other developmental delays, it creates anxiety, preventing a child from sleeping. Delayed Sleep Phase Syndrome: a delay in biorhythms, meaning that even if a teen or adolescent goes to bed, it may not be possible to sleep. During adolescence, the body's circadian rhythm (a kind of internal  clock) is reset. This biological clock tells teens to fall asleep later at night, and  then wake up later in the mornings. This change in the circadian rhythm seems to be due to the fact that the brain hormone melatonin is produced later at night in teens than it is for kids and adults. So, teenagers really do often have a harder time falling asleep — and there's nothing they can do to change that. In addition to grogginess and difficulty waking, there are physical and mental effects of sleep deprivations, such as:  Impaired memory and learning.  Reduced mental health.  Reduced academic outcomes.  Shortened attention span.  Impaired motor skills.  Increased instances of acne.  Decreased metabolism and obesity. Sleep deprivation has a profound impact on neurocognitive function, especially when this deficit occurs over the long term, and especially in adolescent and teen populations.The human brain develops faculties related to logical, systematic thinking between the years of 12 to 18. These skills don't just apply to completing school work.Problem-solving is a universal cognitive skill that affects all aspects of our lives. It is therefore necessary that teens develop and maintain healthy sleep habits to ensure they live up to their full potential as adults. If you are a teen struggling to get enough sleep, there are resources available to you that can help.  Talk to your parents. They can help you with the steps outlined in this article and help you get the assistance you need.  Talk to your doctor.
