Understanding Common Sleep Disorders
A sleep disorder is a condition that impairs sleep quality, duration, or timing, negatively impacting a person’s ability to function during the day. Sleep disorders can stem from medical, psychological, or lifestyle-related factors. Over 70 million Americans suffer from sleep disorders, with insomnia being the most prevalent sleep disorder, affecting 30%–40% of adults at some point in their lives.
The Most Common Sleep Disorders: Insomnia, Sleep Apnea, Restless Legs Syndrome, Narcolepsy, and REM Sleep Behavior Disorder
This section covers the most common sleep disorders, including insomnia, sleep apnea, restless legs syndrome, narcolepsy, and REM sleep behavior disorder. Each disorder has distinct causes, symptoms, and treatment options.
Causes of insomnia include stress, anxiety, and depression, poor sleep hygiene, caffeine and alcohol consumption before bedtime, and medical conditions.

2. Sleep Apnea and Restless Legs Syndrome
