A sleep problem called insomnia is characterised by trouble getting to sleep, remaining asleep, or waking up too early and being unable to go back to sleep.

Obstructive sleep apnea or a malfunctioning brain signal (central sleep apnea) are the common causes of sleep apnea, a disorder in which breathing regularly stops and resumes during sleep.

See a medical professional if, despite following proper sleep hygiene, you have persistent problems falling asleep, if daytime sleepiness interferes with your regular activities, or if you suffer symptoms like loud snoring or gasping from sleep.

Excessive worry, fear, or uneasiness that interferes with day-to-day functioning is the hallmark of an anxiety disorder.

Examples of these disorders include obsessive-compulsive disorder (OCD), panic disorder, social anxiety disorder, generalised anxiety disorder (GAD), and particular phobias.

Persistent concern, restlessness, impatience, tense muscles, trouble concentrating, disturbed sleep, and physical signs like perspiration or a fast heartbeat are some of the symptoms.

Common causes include surgery, infections, nerve damage, medical disorders like fibromyalgia or arthritis, and injuries like sprains or fractures.

Physical therapy, acupuncture, nerve blocks, nonsteroidal anti-inflammatory medicines, and psychiatric therapies like cognitive-behavioural therapy are some of the possible treatments.
