About one-third of adults report some insomnia symptoms, 10-15 percent report problems with functioning during the daytime and 6-10 percent have symptoms severe enough to meet criteria for insomnia disorder. Insomnia, the most common sleep disorder, involves problems getting to sleep or staying asleep. Sleep disturbances can also be a warning sign for medical and neurological problems, such as congestive heart failure, osteoarthritis and Parkinson’s disease. Lack of sleep and too much sleep are linked to many chronic health problems, such as heart disease and diabetes. Sleep problems can exacerbate depression or anxiety, and depression or anxiety can lead to sleep problems. Sleep problems often coexist with symptoms of depression or anxiety. The ability to make decisions and your mood can also be affected. The most obvious concerns are fatigue and decreased energy, irritability and problems focusing. Not getting enough sleep or poor quality sleep has many potential consequences. Sleep helps your brain function properly. 2 Consequences of Lack of Sleep and Coexisting Conditions More than 50 million Americans have chronic sleep disorders. 2 An estimated 35 percent of Americans report their sleep quality as “poor” or “only fair.” 3 Nearly 30 percent of adults get less than six hours of sleep each night and only about 30 percent of high school students get at least eight hours of sleep on an average school night. The Foundation revised its sleep recommendations in 2015 based on a rigorous review of the scientific literature.
According to the National Sleep Foundation most adults need about seven to nine hours of restful sleep each night. How much sleep we need varies depending on age and varies from person to person. Your body typically works on a 24-hour cycle (circadian rhythm) that helps you know when to sleep.
Sleep is a basic human need and is critical to both physical and mental health. Sleep problems can both contribute to or exacerbate mental health conditions and can be a symptom of other mental health conditions.Ībout one-third of adults report insomnia symptoms and 6-10 percent meet the criteria for insomnia disorder. Sleep difficulties are linked to both physical and emotional problems.
Other sleep-wake disorders include obstructive sleep apnea, parasomnias, narcolepsy, and restless leg syndrome. There are several different types of sleep-wake disorders, of which insomnia is the most common. Sleep-wake disorders often occur along with medical conditions or other mental health conditions, such as depression, anxiety, or cognitive disorders. Sleep disorders (or sleep-wake disorders) involve problems with the quality, timing, and amount of sleep, which result in daytime distress and impairment in functioning.
