Sleep disorders involve problems with the quality, timing and amount of sleep, which cause problems with functioning and distress during the daytime. There are a number of different types of sleep disorders, of which insomnia is the most common. Other sleep disorders are narcolepsy, obstructive sleep apnea and restless leg syndrome.
Sleep difficulties are linked to both physical and emotional problems. Sleep problems can both contribute to or exacerbate mental health conditions and be a symptom of other mental health conditions.
Sleep helps your brain function properly. Not getting enough sleep or poor quality sleep has many potential consequences. The most obvious concerns are fatigue and decreased energy, irritability and problems focusing. The ability to make decisions and mood can also be affected. Sleep problems often coexist with symptoms of depression or anxiety. Sleep problems can exacerbate depression or anxiety, and depression or anxiety can lead to sleep problems.
Lack of sleep and too much sleep are linked to many chronic health problems, such as heart disease and diabetes. Sleep disturbances can also be a warning sign for medical and neurological problems, such as congestive heart failure, osteoarthritis and Parkinson’s disease.
