Sleep Disorders

Sleep disorders are a group of conditions that affect how a person sleeps, how long they sleep, and how refreshed they feel after sleep. Common types include insomnia, sleep apnea, narcolepsy, restless legs syndrome, circadian rhythm disorders, and parasomnias such as sleepwalking or night terrors. People with these disorders may struggle to fall asleep, wake up many times at night, snore loudly, gasp for air, or feel sleepy during the day even after spending enough time in bed. Some sleep disorders are linked to breathing problems, while others are related to the body’s internal clock, nerve activity, or abnormal behavior during sleep.
Poor sleep can reduce concentration, mood, and energy, and it may increase the risk of accidents, heart disease, stroke, and diabetes if left untreated. Treatment depends on the cause and may include better sleep habits, stress management, medicines, devices for breathing problems, or specialist care. Early evaluation is important because many sleep disorders improve when the underlying problem is identified and treated properly.
