Sleep disorders are a group of conditions that affect the ability to sleep well on a regular basis. These disorders can range from insomnia, which involves difficulty falling asleep or staying asleep, to sleep apnea, which involves pauses in breathing during sleep. Other common sleep disorders include narcolepsy, restless leg syndrome, and parasomnias like sleepwalking or night terrors. These disorders can impact a person's overall health and well-being, leading to daytime fatigue, difficulty concentrating, and other negative outcomes. Treatment for sleep disorders often involves a combination of lifestyle changes, therapy, and medication.
