Common sleep disorders include insomnia, sleep apnea, restless legs syndrome (RLS), and narcolepsy.

Insomnia: Difficulty falling or staying asleep.
Sleep apnea: Breathing repeatedly stops and starts during sleep.
Restless legs syndrome: An uncontrollable urge to move the legs, usually at night.
Narcolepsy: Excessive daytime sleepiness and sudden sleep attacks.

Each of these conditions can significantly impact sleep quality, daytime energy, mood, and long-term health.

Taking a free, instant, online symptom check can help you better understand your symptoms, identify possible causes, and confidently plan your next steps toward better sleep and health.
