Common Sleep Disorders—and What You Should Know

Sleep problems are more than just a nuisance—they can affect your energy, mood, memory, and overall health. If you often feel tired during the day or struggle to fall or stay asleep, a sleep disorder may be the cause.

Here are some of the most common types of sleep disorders:


💤 Insomnia

The most common sleep problem. You may have trouble falling asleep, wake up frequently during the night, or wake too early and not be able to fall back asleep. Insomnia can leave you feeling tired, irritable, or unfocused the next day.


😮‍💨 Sleep Apnea

Sleep apnea is a condition where breathing stops and starts during sleep, often due to a blocked airway. Loud snoring, gasping, and daytime fatigue are common signs. It can raise the risk of heart disease, so treatment is important.


🦵 Restless Legs Syndrome (RLS)

RLS causes uncomfortable sensations in the legs—tingling, crawling, or aching—that create a strong urge to move them. Symptoms are usually worse at night and can interfere with falling asleep.

Circadian Rhythm Disorders

Your body has a natural clock. When it’s out of sync—like after travel, shift work, or certain medical conditions—you may struggle to fall asleep or stay awake at the right times.


🧠 Parasomnias and Hypersomnia

Parasomnias include unusual behaviors like sleepwalking, talking in sleep, or night terrors. Hypersomnia means sleeping too much but still feeling unrefreshed or groggy during the day.


Many people live with undiagnosed sleep disorders—but effective treatments are available. If you think you may have a sleep disorder, talk with your doctor or a sleep specialist. Understanding your sleep is the first step toward better rest.
