What Are Sleep Disorders?
Sleep disorders are conditions that affect your ability to fall asleep, stay asleep, breathe normally during sleep, or feel rested during the day. They can affect sleep quality, daytime energy, concentration, mood, and overall quality of life.
Some sleep problems may be temporary, while others can continue for months or require medical evaluation. Identifying the underlying cause is an important step toward better sleep.
Common Types of Sleep Disorders
Insomnia
Difficulty falling asleep, staying asleep, or waking too early can leave you tired and unrefreshed during the day.
Narcolepsy
Narcolepsy can cause excessive daytime sleepiness and sudden episodes of falling asleep.
Sleep Apnea
Sleep apnea can cause repeated interruptions in breathing during sleep and is often associated with loud snoring and daytime tiredness.
Restless Legs Syndrome
Restless legs syndrome can cause uncomfortable sensations in the legs and an uncontrollable urge to move them, particularly at night.
Circadian Rhythm Disorders
These disorders occur when your body’s internal sleep-wake schedule becomes misaligned with your daily routine or environment.
Parasomnias
Parasomnias involve unusual behaviors or experiences during sleep, such as sleepwalking, night terrors, or certain abnormal movements.
Signs You May Have a Sleep Disorder
Common symptoms can include:
- Difficulty falling asleep
- Frequently waking during the night

Sleep Disorder Treatment
Better Sleep Habits
Developing consistent sleep and wake times and improving your sleep environment can support healthier sleep.
Behavioral Therapy
Certain sleep problems, particularly chronic insomnia, may benefit from behavioral approaches such as cognitive behavioral therapy.
Treating Underlying Conditions
If another medical or psychological condition is affecting sleep, treating that underlying problem may improve sleep.
Medication When Appropriate
In some situations, doctors may recommend medication. The choice depends on the type and cause of the sleep problem and should be medically supervised.
Simple Habits for Better Sleep
- Keep a consistent sleep schedule
- Reduce screen exposure before bed
- Limit caffeine later in the day
- Stay physically active
- Keep your bedroom comfortable and quiet
- Avoid heavy meals close to bedtime
- Create a relaxing bedtime routine
When Should You See a Doctor for Sleep Problems?
Consider speaking with a doctor if you:
- Regularly have difficulty sleeping
- Feel excessively sleepy during the day
- Snore loudly or frequently
- Wake up gasping or choking
- Frequently wake during the night
- Feel unrefreshed despite getting enough time in bed
- Have sleep problems that interfere with work or daily activities
- Experience persistent unusual behaviors or movements during sleep
Persistent sleep problems can affect concentration, mood, daily functioning, and long-term health, so ongoing symptoms deserve medical attention
Frequently Asked Questions About Sleep Disorders

Sleep disorders are conditions that affect how well you sleep, how long you sleep, or your sleep-wake cycle. Common sleep disorders include insomnia, sleep apnea, restless legs syndrome, narcolepsy and circadian rhythm sleep disorders. Sleep disorder symptoms can include difficulty falling asleep, frequent waking, excessive daytime sleepiness, loud snoring and abnormal breathing during sleep.
Common sleep disorder symptoms include difficulty falling or staying asleep, waking too early, excessive daytime sleepiness, loud or persistent snoring, pauses in breathing during sleep, morning headaches, restless sleep and difficulty concentrating during the day. Symptoms can vary depending on the type of sleep disorder.
There are several types of sleep disorders, including insomnia, sleep apnea, restless legs syndrome, narcolepsy, parasomnias and circadian rhythm sleep disorders. Some people may have more than one sleep disorder at the same time.
Sleep disorders can have many causes, including stress, anxiety, medical conditions, medications, lifestyle factors, irregular sleep schedules and environmental factors. Some conditions, such as sleep apnea or restless legs syndrome, may have specific underlying risk factors that require medical evaluation.
Yes. Insomnia is a common sleep disorder characterized by difficulty falling asleep, staying asleep or getting adequate restorative sleep despite having an opportunity to sleep. Persistent insomnia may affect daytime energy, concentration and overall well-being.
Sleep apnea is a sleep disorder in which breathing repeatedly stops or becomes reduced during sleep. Obstructive sleep apnea is the most common type and occurs when the upper airway becomes blocked during sleep. Loud snoring, witnessed breathing pauses, gasping during sleep and excessive daytime sleepiness can be possible symptoms.
You should consider speaking with a doctor if sleep problems are persistent, interfere with daily activities, or cause significant daytime sleepiness or difficulty concentrating. Loud snoring, witnessed pauses in breathing, gasping during sleep or persistent insomnia may also warrant medical evaluation.
Sleep disorders are diagnosed based on your symptoms, medical history, sleep patterns and physical examination. Depending on the suspected condition, a doctor may recommend a sleep diary, sleep questionnaire, blood tests or a sleep study such as polysomnography. Some people may also need specialized testing.
A sleep study, also called polysomnography, is a test that records different body functions while you sleep. Depending on the type of study, it may monitor breathing, oxygen levels, heart rate, brain activity, eye movements and muscle activity to help identify certain sleep disorders.
Yes. Some sleep disorders can cause excessive daytime sleepiness, particularly when sleep is repeatedly interrupted or does not provide adequate restorative rest. Daytime sleepiness may affect concentration, reaction time, mood and daily functioning.
Poor sleep and certain sleep disorders can be associated with changes in mood, concentration and emotional well-being. Sleep problems may occur alongside conditions such as anxiety or depression, but persistent sleep difficulties should be evaluated rather than assumed to have one specific cause.
Sleep disorder treatment depends on the type and underlying cause of the condition. Treatment may include changes to sleep habits, behavioral therapies, treatment of an underlying medical condition, medicines in selected cases, or devices such as CPAP for certain people with obstructive sleep apnea.
Some sleep disorders can improve with behavioral and lifestyle approaches, depending on the underlying condition. For example, cognitive behavioral therapy for insomnia (CBT-I) is an established treatment for chronic insomnia. Treatment should be selected according to the specific sleep disorder and individual circumstances.
Snoring can occur for many reasons and does not always mean someone has a sleep disorder. However, loud or persistent snoring accompanied by pauses in breathing, choking or gasping during sleep, or excessive daytime sleepiness may be associated with sleep apnea and should be medically evaluated.
A sleep specialist can evaluate and manage many sleep disorders. Depending on the symptoms and suspected condition, care may also involve a pulmonologist, neurologist, psychiatrist, ENT specialist or another healthcare professional.
Yes. Sleep disorders can affect children and teenagers as well as adults. Sleep problems in younger people may appear as difficulty sleeping, unusual nighttime behaviors, breathing problems during sleep, excessive daytime sleepiness or changes in daytime behavior and concentration.
Healthy sleep habits may include maintaining a consistent sleep and wake schedule, creating a comfortable and quiet sleep environment, limiting caffeine later in the day, avoiding excessive screen exposure close to bedtime and getting regular physical activity. Persistent sleep problems should be discussed with a healthcare professional.
Some sleep disorders can affect overall health when they remain untreated, particularly when they cause chronic sleep deprivation or repeated interruptions in breathing. The potential effects depend on the specific disorder, its severity and the person's overall health.
