Sleep disorders are conditions that affect the ability to get enough quality sleep. They can involve difficulties falling asleep, staying asleep, or sleeping too much. Common sleep disorders include insomnia, sleep apnea, restless legs syndrome, and narcolepsy. These disorders can lead to daytime sleepiness, fatigue, and difficulty concentrating, affecting overall well-being and quality of life. Causes may include stress, lifestyle factors, medical conditions, or underlying sleep disorders. Diagnosis often involves sleep studies and medical evaluations. Treatment options vary depending on the specific disorder and may include lifestyle changes, medications, or behavioral therapies aimed at improving sleep quality and duration.
