Insomnia/Fatigue

Insomnia is a type of sleep disorder. Individuals with insomnia find it difficult to fall asleep, stay asleep, or both. People with insomnia often don’t feel refreshed when they wake up from sleeping, either. This can lead to fatigue and other symptoms.

Fatigue is a term used to describe an overall feeling of tiredness or lack of energy. It isn’t the same as simply feeling drowsy or sleepy. When you’re fatigued, you have no motivation and no energy. Being sleepy may be a symptom of fatigue, but it’s not the same thing.

Fatigue is a common symptom of many medical conditions that range in severity from mild to serious. It’s also a natural result of some lifestyle choices, such as lack of exercise or poor diet.

Insomnia

Short-term insomnia may be caused by stress, an upsetting or traumatic event, or changes to your sleep habits.

Chronic insomnia lasts for at least three months and is usually secondary to another problem or a combination of problems, including:

• medical conditions which make it harder to sleep, such as arthritis or back pain
• psychological issues, such as anxiety or depression
• substance use
