Insomnia is a common and prevalent sleep disorder affecting millions globally, and it is characterized by difficulty falling and staying asleep or waking up too early. Insomnia can be acute or chronic, significantly impacting a person’s overall health and well-being.

Acute insomnia is typically short-term and may be caused by stress, jet lag, or other environmental factors. On the other hand, chronic insomnia is usually a long-term problem that various factors, including depression, anxiety, chronic pain, or medical conditions such as sleep apnea, can cause.

The symptoms of insomnia can vary significantly from person to person. They may include difficulty falling asleep, difficulty maintaining sleep, fragmentation of sleep, waking up frequently during the night, early morning awakening or waking up too early, feeling tired or not rested after waking up in the morning, and daytime sleepiness or fatigue. Insomnia can also lead to mood disturbances, such as anxiety or depression, and impair a person’s ability to function at work or in other areas.

Treatment for insomnia often involves lifestyle changes, such as improving sleep hygiene, avoiding caffeine or alcohol before bedtime, and reducing stress. Medication or other therapies may sometimes be necessary to help manage insomnia symptoms. It is essential to seek treatment for insomnia, as untreated insomnia can seriously impact physical and mental health.
