Headaches are one of the most common health grievances of students, adults and even children, Headaches are very common and usually do not point to a serious illness. But even a mild headache can disrupt your daily activities

What actually happens in your body to cause headache?

The skull bones and brain tissues do not have pain sensitive nerve fibers. But muscles of face, mouth, throat, neck, scalp and blood vessels on the surface and base of brain are sensitive to pain as they contain pain sensitive nerve fibers.

The tip of these nerve fibers gets stimulated by various causes like stress, muscle tension, lack of sleep etc. The stimulated nerve tip sends message up the length of the nerve fiber to the related nerve cells of Brain. Brain locates the region of stimulated nerve tip based on these signals and we feel the pain or ache.

The headache may be mild, chronic or severe depending on the underlying cause and pain bearing capacity of the individual. Our body produces natural pain killing proteins called endorphins. One of the theories suggests that people with low endorphin levels suffer from severe headache and other chronic pains in comparison with people having high endorphin levels.
