Insomnia is one of the most prevalent sleep disorders and can significantly impact overall health and quality of life. Early diagnosis, healthy sleep habits, treatment of underlying causes, and adherence to an appropriate treatment plan can help improve sleep and reduce the long-term complications associated with insomnia.

Insomnia is one of the most common sleep disorders and is characterized by difficulty falling asleep, staying asleep, or waking up too early and being unable to return to sleep. It can negatively affect daily functioning as well as physical and mental health.

Causes

Insomnia may result from a variety of factors, including:

• Stress, anxiety, and psychological pressure.
• Depression and other mental health disorders.
• Chronic medical conditions such as chronic pain, asthma, and gastroesophageal reflux disease (GERD).
• Certain medications that interfere with sleep.
• Poor sleep habits, such as irregular sleep schedules or the use of electronic devices before bedtime.
• Environmental factors, including noise and excessive light.
• Consumption of caffeine, nicotine, or alcohol.

Symptoms

Common symptoms of insomnia include:

• Difficulty falling asleep or staying asleep.
• Frequent awakenings during the night.
• Early morning awakening with inability to return to sleep.
• Feeling tired or unrefreshed upon waking.

Melatonin and Its Role in Treating Insomnia

Melatonin is a naturally occurring hormone that helps regulate the sleep–wake cycle. Melatonin supplements may be used to improve sleep in certain situations, particularly for circadian rhythm disorders or temporary sleep difficulties. It is recommended to consult a healthcare professional before use.

Although melatonin is generally considered safe when used appropriately, it may cause some side effects, including:

• Headache.
• Dizziness.
• Nausea.
• Daytime drowsiness.
• Vivid dreams or nightmares.

Melatonin may also interact with certain medications and medical conditions; therefore, medical advice should be sought before use.

Potential Complications of Insomnia

Chronic insomnia may lead to:

• Impaired cognitive performance and concentration.
• Increased risk of accidents and injuries.
• Mood disorders and depression.
• Higher risk of cardiovascular disease and hypertension.
• Reduced quality of life and daily productivity.
