The headaches you may suffering from may be nothing more than dehydration headaches.
A dehydration headache is another of the numerous dehydration signs.
In fact, it may be difficult to experience a headache if your body and brain are fully hydrated.
Here's why
The brain is lord of organs. As lord, when it starts to feel deprived of water or when it starts to feel overheated, it commands extra fluid, in the form of blood to itself.
When this occurs, the arteries leading up to the brain, those closest to it, start expanding with the extra blood. That would be the arteries in the temple and face region.
This is how headaches begin. As blood rushes to the brain you start feeling that familiar throbbing sensation in the temples and your face becomes flushed with blood.
Dehydration of the brain leads to a dehydration headache and can occur if you are stressed, or drink alcohol or overheat, like during a workout, for example.
The solution
The solution is simple. If you are not suffering from any other physical compromise and your dehydration hasn't set in as chronic and permanent, just drink water.
Drink several glasses of cool water immediately upon sensing a headache and make sure to sip water throughout the day.
This should be all you need to do to reduce or eliminate your headaches.
