Sleep is essential for physical and mental well-being. Sleep disorders are medical conditions that disrupt the quality, timing, or amount of sleep, leading to daytime impairment and psychological stress. Recognizing sleep disorders can help individuals seek appropriate medical or psychological treatment.
What Are Sleep Disorders?
Sleep disorders refer to a group of conditions that interfere with the ability to sleep well on a regular basis. They may involve trouble falling asleep, staying asleep, or maintaining a regular sleep-wake cycle. These conditions can also result in excessive daytime sleepiness or difficulty staying awake.
What are the Common Types of Sleep Disorders?
