There are several different kinds of headaches. The most common type of headache is the tension headache.
The exact cause of these types of headaches is unknown, but there are several factors that have been shown in many cases to cause or at least play a part in tension headaches. This includes things like caffeine withdrawal, eye strain, and stress. Other things like teeth clenching, which results in muscle tension, and other strains on the muscles, has been also been shown to play a part in these types of headaches.

Headaches can be caused by a variety of factors. One of the more common causes of headaches is as a result of dehydration. Dehydration is when the body looses water, which is not replenished. Things like heavy exercise or extreme heat can overheat the body and cause dehydration. In some instances dehydration can cause death or serious illness, but this is only if it goes untreated.One of the early signs of dehydration is a headache. When your body is not properly hydrated, it begins to pump blood to the brain to compensate for the loss of fluids. This causes the blood vessels that are closest to your brain, specifically the ones near the eyes and temples, to expand with blood. This expansion causes the area in and around the temples to begin to throb, and often signals the beginning of a bad headache.
It is very important to stay properly hydrated, and by doing so you can prevent headaches that are caused by dehydration. One common misconception is that caffeinated soda and coffee is hydrating, but this is anything but true. Caffeine is actually a diuretic, which increases the release of urine from the body. As you loose water without replenishing it, your body begins to become dehydrated.
Water is by far the best fluid to hydrate your body. There are plenty of other drinks available that can help with dehydration, and many include extra nutrients and vitamins. When you start to feel a headache, or that familiar throb, it is a good idea to begin hydrating your body with water.
