Sleep disorders are changes in the way that you sleep.
A sleep disorder can affect your overall health, safety and quality of life. Sleep deprivation can affect your ability to drive safely and increase your risk of other health problems.
Some of the signs and symptoms of sleep disorders include excessive daytime sleepiness, irregular breathing or increased movement during sleep, and difficulty falling asleep.
There are many different types of sleep disorders. They're often grouped into categories that explain why they happen or how they affect you. Sleep disorders can also be grouped according to behaviors, problems with your natural sleep-wake cycles, breathing problems, difficulty sleeping or how sleepy you feel during the day.
Some common types of sleep disorders include:
- Insomnia, in which you have difficulty falling asleep or staying asleep throughout the night.
- Sleep apnea, in which you experience abnormal patterns in breathing while you are asleep. There are several types of sleep apnea.
- Restless legs syndrome (RLS), a type of sleep movement disorder. Restless legs syndrome, also called Willis-Ekbom disease, causes an uncomfortable sensation and an urge to move the legs while you try to fall asleep.
- Narcolepsy, a condition characterized by extreme sleepiness during the day and falling asleep suddenly during the day.
There are many ways to help diagnose sleep disorders. Doctors can usually treat most sleep disorders effectively once they're correctly diagnosed.
