The comment about water is ridiculous. The picture in the article is ridiculous. Cluster Headaches are an excruciatingly severe neurological condition that is quite rare. There is no research or evidence that I have read about that specifically suggests that dehydration has anything at all to do with Cluster Headaches. People with this disorder actually have an abnormality in their hypothalamus. The picture is wrong for this article because people going through Cluster Headaches have such severe pain that they cannot touch their face–let alone press on it like the picture. This is not a diagnosis or discussion that should be taken lightly. The article also says the pain is around the “eyes” –that is not correct. The pain for Cluster headaches is almost always unilateral and only around one “eye”. In general the article needs some work. Sumatriptan is one option, not “the” option. Two categories of drugs are used–those that help abort individual headaches–like the oxygen does–and those that attempt to break up the cycle or suppress the headaches while in a cycle.

Most people are dehydrated.

In other words they do not drink enough water..

The equivalent of eight or nine glasses of water every day is needed by everyone.

It is often the lack of water – that causes head aches. Even migraine headaches.

Drinking enough water will often cause headaches to disappear
