Sleepwalking is a sleep disorder where a person gets up and walks or performs activities while still asleep. It usually happens during deep non-REM sleep and is more common in children, though adults can experience it too.

Sleep paralysis is a temporary inability to move or speak that happens when falling asleep or waking up. Although it can feel frightening, it is usually harmless and lasts from a few seconds to a couple of minutes.

Night terrors are intense episodes of fear that occur during deep non-REM sleep, usually in the first third of the night. Unlike nightmares, the person is often not fully awake and usually does not remember the episode in the morning.

Circadian rhythm sleep–wake disorders occur when your internal biological clock is out of sync with the external day–night cycle. Even if you have enough time to sleep, your body simply wants to sleep and wake at the “wrong” times.

Shift work sleep disorder affects people who work night shifts, rotating shifts, or very early morning schedules. It happens when your work hours conflict with your natural biological clock, making it difficult to sleep properly and stay alert when needed.

REM sleep behavior disorder is a condition where a person physically acts out vivid dreams during REM sleep. Instead of being temporarily paralyzed as we normally are in REM sleep, the body moves — sometimes violently — which can lead to injury.

Narcolepsy is a chronic neurological sleep disorder that affects the brain’s ability to regulate sleep and wakefulness. People with narcolepsy often feel overwhelming daytime sleepiness and may suddenly fall asleep without warning.

Restless legs syndrome is a neurological sleep disorder that causes an overwhelming urge to move the legs, usually in the evening or at night. It can make falling asleep extremely difficult and lead to chronic sleep deprivation.

Insomnia disorder is one of the most common sleep problems worldwide. It is not just about sleeping less — it is about struggling to fall asleep, stay asleep, or waking too early, even when you have enough opportunity to sleep.
