What causes Tension headache?
Tension headaches are one of the most common forms of headaches. They may occur at any age, but are most common in adults and adolescents.
If a headache occurs two or more times a week for several months or longer, the condition is considered chronic. Chronic daily headaches can result from the under- or over-treatment of a primary headache.
Rebound headaches are headaches that keep coming back. They may occur if you overuse painkillers.
Tension headaches occur when neck and scalp muscles become tense, or contract. The muscle contractions can be a response to stress, depression, a head injury, or anxiety.
Any activity that causes the head to be held in one position for a long time without moving can cause a headache. Such activities include typing or other computer work, fine work with the hands, and using a microscope. Sleeping in a cold room or sleeping with the neck in an abnormal position may also trigger a tension headache.
Other triggers of tension headaches include:
Alcohol use Caffeine (too much or withdrawal) Colds, the flu, or a sinus infection Dental problems such as jaw clenching or teeth grinding Eye strain Excessive smoking Fatigue or overexertion
Tension headaches can occur when you also have a migraine. Tension headaches are not associated with brain diseases. </s>
