Many teens don't get enough sleep, usually because they're busy and tend to skimp on sleep. But sleep problems can keep some teens awake at night even when they want to sleep. Over time, those nights of missed sleep whether they're caused by a sleep disorder or simply not scheduling enough time for the necessary ZZZs can build into a sleep deficit. People with a sleep deficit are unable to concentrate, study, and work effectively.
They can also have emotional problems, like depression. You don't notice it, of course, but while you're asleep, your brain is still active. As people sleep, their brains pass through five stages of sleep. Together, stages 1, 2, 3, 4, and REM rapid eye movement sleep make up a sleep cycle.
One complete sleep cycle lasts about 90 to minutes. So during an average night's sleep, a person will experience about four or five cycles of sleep. Stages 1 and 2 are periods of light sleep from which a person can wake up easily. During these stages, eye movements slow down and eventually stop, heart and breathing rates slow down, and body temperature decreases. Stages 3 and 4 are deep sleep stages.
It's more difficult to awaken someone during these stages, and when awakened, a person will often feel groggy and confused for a few minutes.
Stages 3 and 4 are the most refreshing of the sleep stages — it is this type of sleep that we crave when we are very tired. The final stage of the sleep cycle is known as REM sleep because of the rapid eye movements that occur during this stage. During REM sleep, other physical changes take place — breathing becomes rapid, the heart beats faster, and the limb muscles don't move. This is the stage of sleep when a person has the most vivid dreams.
You don't need to be a math whiz to figure out that if you wake up for school at a. Studies have found that many teens have trouble falling asleep that early, though. It's not because they don't want to sleep. It's because their Can t sleep trying to meet a nice guy naturally work on later schedules and aren't ready for bed. During adolescence, the body's circadian rhythm sort of like an internal biological clock is reset, telling a teen to fall asleep later at night and wake up later in the morning.
This change in the circadian rhythm seems to happen because a teen's brain makes the hormone melatonin later at night than the brains of kids and adults do. Melatonin and another hormone, serotonin, help regulate a person's sleep—wake cycles. So, teens have a harder time falling asleep. Sometimes this delay in the sleep—wake cycle is so severe that it affects a person's daily activities. In those cases it's called delayed sleep phase syndrome or "night owl" syndrome. This isn't the only reason teens lose sleep, though.
Lots of people have insomnia — trouble falling or staying asleep. The most common cause of insomnia is stress. But all sorts of things can lead to insomnia, including physical discomfort the stuffy nose of a cold or the pain of a headache, for exampleemotional troubles like family problems or relationship difficultiesand even an uncomfortable sleeping environment a room that's too hot, cold, bright, or noisy.

But if insomnia lasts for a Can t sleep trying to meet a nice guy or longer with no relief, then doctors call it chronic. Chronic insomnia can be caused by a of different problems, including medical conditions, mental-health problems, medication side effects, or substance abuse. People with chronic insomnia usually can get help for it from a doctor, therapist, or other counselor. Worrying about the insomnia can make it even worse for some people.
A brief period of insomnia can build into something longer lasting when a person becomes anxious about not sleeping or worried about feeling tired the next day. Doctors call this psychophysiologic insomnia. People with periodic limb movement disorder PLMD or restless legs syndrome RLS find their sleep is disrupted by leg or, less commonly, arm movements, leaving them tired or irritable from lack of sleep.
In the case of PLMD, these movements are involuntary twitches or jerks: They're called involuntary because the person isn't consciously controlling them and is often unaware of the movement. People with RLS actually feel physical sensations in their limbs, such as tingling, itching, cramping, or burning. The only way they can relieve these feelings is by moving their legs or arms to get rid of the discomfort.
For some people, treating an iron deficiency can make them go away; others might need to take other types of medication. A person with obstructive sleep apnea temporarily stops breathing during sleep because the airway becomes narrowed or blocked. One common cause of obstructive sleep apnea is enlarged tonsils or adenoids tissues located in the passage that connects the nose and throat.
Being overweight or obese also can put someone at risk for it. People with this sleep disorder may snore, have difficulty breathing, and even sweat heavily during sleep. Because it disrupts sleep, a person may feel extremely sleepy or irritable during the day. People who show s of obstructive sleep apnea, such as loud snoring or excessive daytime sleepiness, should talk to their doctor. In gastroesophageal reflux disease GERDstomach acid moves backward up into the esophagus, producing the uncomfortable, burning sensation known as heartburn.
GERD symptoms can be worse when someone is lying down. Even if a person doesn't notice the feelings of heartburn during sleep, the discomfort it causes can still interfere with the sleep cycle. Most teens have nightmares once in a while. But frequent nightmares can disrupt sleep patterns by waking someone during the night. The most common triggers for more frequent nightmares are emotional, such as stress or anxiety. Other things that can trigger them include certain medicines, and consuming drugs or alcohol.

Someone's nighttime sleep may be disrupted, with frequent awakenings throughout the night.
Narcolepsy can be disturbing because people fall asleep without warning, making it hazardous to do things like drive. A person's school, work, or social life can be affected by the unusual sleep patterns. Narcolepsy isn't common diagnosed in teens, but many cases go unrecognized. People usually first begin to have symptoms between the ages of 10 and 25, but may not be properly diagnosed until 10—15 years later.
Doctors usually treat narcolepsy with medicines and lifestyle changes. It's rare for teens to walk in their sleep; most sleepwalkers are. Sleepwalking, which may run in families, tends to happen most often when a person is sick, has a fever, is not getting enough sleep, or is feeling stress. Because most sleepwalkers don't sleepwalk often, it's not usually a serious problem.
Sleepwalkers tend to go back to bed on their own and don't usually remember sleepwalking. Sleepwalking often happens during the deeper sleep that takes place during stages 3 and 4 of the sleep cycle. Sometimes, though, a sleepwalker will need help moving around obstacles and getting back to bed. It's also true that waking sleepwalkers can startle them but it isn't harmfulso try to guide a sleepwalker back to bed gently.

If a sleep problem is suspected, your doctor will look at your overall health and sleep habits. In addition to doing a physical examination, the doctor will take your medical history by asking you about any concerns and symptoms you have, your past health, your family's health, any medications you're taking, any allergies you may have, and other issues.
The doctor also might do tests to find out whether any conditions — such as obstructive sleep apnea — might be interfering with your sleep. Treatment for sleep problems can vary. Some can be treated with medicines, while others can be helped with special techniques like light therapy where someone sits in front of a lightbox for a certain amount of time each day or other practices that can help reset a person's body clock. Doctors also encourage teens to make lifestyle changes that promote good sleeping habits.
You probably know that caffeine can keep you awake, but many teens don't realize that texting and using mobile devices, playing video games, or watching TV before sleeping can, too.
