Most Common Sources of headache

The cause of the most commonly reported headache, tension headaches, is actually still unknown. An estimated 75 percent to 90 percent of people who complain of frequent headaches are suffering from tension headaches.

Some experts believe they stem from contracted muscles, while others believe they're related to changes in your brain chemicals, such as serotonin, endorphins and others, which help your nerves communicate.

The good news is that these headaches are rarely the sign of something serious (see the end of the article for some rare, but serious, causes). Instead, tension-type headaches are related to lifestyle factors that you can influence.

1;-Stress
