Causes

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 2 or more times weekly for several months or longer, the condition is considered chronic. Tension headaches can occur when the patient also has a migraine.

Tension headaches result from the contraction (tensing) of neck and scalp muscles. One cause of this muscle contraction is a response to stress, depression, 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 use of computers, fine work with the hands, and use of a microscope. Sleeping in a cold room or sleeping with the neck in an abnormal position may also trigger this type of headache.

Other causes include eye strain, fatigue, alcohol use, excessive smoking, excessive caffeine use, sinus infection, nasal congestion, overexertion, colds, and influenza. Tension headaches are not associated with structural abnormalities in the brain.
