What is a sleep disorder?
Sleep disorders are conditions that result in 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. Other signs and symptoms include an irregular sleep and wake cycle 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.
What are the symptoms of a sleep disorder?
Symptoms of sleep disorders vary depending on the type of sleep disorder. The symptoms may range from mild to severe and usually include one or more of the following: hypersomnia (excessive daytime sleepiness), insomnia (decreased sleep efficiency with unrestful sleep with frequent waking up in the night), loud snoring and/or brief pauses in breathing (short periods of apnea), leg movements or an urge to move the legs at night, sleepwalking, or night terrors (nightmares).
