Nearly all of us experience headaches from time to time. Pain felt behind the head, above the ears, above the eyes, or behind the upper neck is considered headache. It has various causes. Headaches can be grouped into two types, the primary headaches and the secondary headaches. Primary headaches are not symptoms of other diseases. Under this type includes tension, migraine, and cluster headaches. The most common kind is the tension headache, while migraine comes in second. Migraines are usually the type that is not diagnosed properly, leaving it untreated. For both tension and migraine headaches, women are more affected compared to men. The most unusual kind among the three primary headaches is the cluster headache. Those who suffer from this are usually men ages 28 to 30 on the average. On the other hand, headaches that are caused by other factors, from less serious to critical illnesses, are classified as secondary headaches. Most people do not only suffer one category of headache; rather they have mixed types of headaches. To know more about headaches, below are only some of its causes.

One of the common causes of headaches is eye problems. If you have eye defect, such as astigmatism and far-sightedness, and you do not wear glasses or contact lenses to correct it, there is a high percentage of getting headaches from time to time. With blurry eyes, you try to focus your vision. Squinting and straining your eyes can definitely cause headache. In a more severe case, glaucoma, an eye disease, can also pose headaches as one of its symptoms.

There are several disorders that bring about headaches. Usually these illnesses have something to do with the ear, nose, throat, and the nervous system. General examples of these are the following: tonsillitis, trauma, tumor, sinus problems, infection, hemorrhages, and labyrinthitis.

Diet also contributes in getting headaches. If you are used to drinking coffee or tea and you suddenly try withdrawing from anything that has caffeine, you will probably feel pain in your head until you have completely adjusted. MSG, chemicals found in foods like amines, and changes in blood sugar levels can also be factors in having headaches.

Some of the bad effects of stress are lower pain tolerance, tightening of the muscles, nullifying pain reliever effects, and lower levels of endorphins, which are body chemicals that act as painkillers. All of these effects can result to headaches.

As said earlier, a lot of women get migraines. One of the factors point to changes in hormones. An example is level of estrogens falls during menstruation which proves why most women have migraines before or after their cycle.
