What is the definition of Insomnia?

Insomnia is a common sleep disorder that can make it difficult to fall asleep, stay asleep, or both. It can cause a wide range of symptoms, including:

- Difficulty falling asleep

- Waking up frequently during the night

- Waking up too early in the morning

- Feeling tired, irritable, and moody during the day

- Difficulty concentrating

- Headaches and muscle pain

Insomnia can be short-term (acute) or long-term (chronic). Acute insomnia usually lasts for a few days or weeks, while chronic insomnia lasts for three months or more.

There are many different causes of insomnia, including:

- Stress: Stress is one of the most common causes of insomnia. When you're stressed, your body releases hormones like cortisol, which can make it difficult to fall asleep.

- Medical conditions: Some medical conditions, such as pain, heart disease, and diabetes, can cause insomnia.

- Medications: Certain medications, such as antidepressants, decongestants, and steroids, can cause insomnia as a side effect.

- Lifestyle factors: Some lifestyle factors, such as caffeine and alcohol consumption, smoking, and irregular sleep habits, can contribute to insomnia.

Insomnia can be a serious problem, but it can be treated. If you're experiencing insomnia, talk to your doctor. They can help you identify the cause of your insomnia and recommend a treatment plan.
