But if you often have trouble getting to sleep or staying asleep, you may have a sleep-wake disorder. These sleep problems can eventually lead to serious health issues.Here’s a look at what sleep-wake disorders are, and how to get your sleep cycle back on track.What Are Sleep-Wake Disorders?Your body has an inner clock that operates on a 24-hour cycle \u2014 otherwise known as circadian rhythms. This inner clock controls sleeping and waking, and it’s different from person to person. To some extent, your individual circadian rhythms determine whether you’re a night owl or a morning lark.For many people, however, this internal rhythm gets disrupted. Sleep-wake disorders occur when your body’s inner clock is out of sync with day and night. These disorders are often related to the amount of light you get.An estimated 50 to 70 million people in the U.S. have ongoing sleep disorders, including sleep apnea, insomnia, and sleep-wake disorders. Doctors don’t know exactly how many people have sleep-wake disorders. People don’t always go the doctor for sleep-wake disorders.What Are The Types of Sleep-Wake Disorders?There are different types of sleep-wake disorders, such as:Advanced sleep-wake phase disorder \u2014 you have a hard time staying awake in the evening. As a result, you wake up too early in the morning. This disorder is more common in older people.Delayed sleep-wake phase disorder \u2014 you fall asleep later than you want to. Consequently, you have a hard time getting up in the morning. This sleep disorder is more common in teens and young adults, and it can interfere with work or school.Non-24-hour sleep-wake disorder \u2014 your sleep-wake cycle is completely out of sync with day and night. You may end up going to sleep in the middle of the day. It’s more common with people who are blind or have no lighting cues from the environment.Irregular sleep-wake rhythm disorder \u2014 you have shorter periods of sleep interrupted by periods of wakefulness. You may not be able to sleep at night or have a hard time getting back to sleep if you wake up. You may need to nap during the day, or never feel fully rested.Jet lag disorder \u2014 a temporary problem when you travel across time zones. Your body clock is out sync with the local time zone. You may feel sleepy or wide awake at the wrong time of day.Shift work disorder \u2014 this can happen when you work nights or rotating shifts. Your body may not be able to get solid, uninterrupted sleep. It can lead to insomnia and sleepiness at work.What Causes of Sleep-Wake Disorders?Sleep-wake disorders happen when your sleep patterns get disrupted.
