When you say you have a headache, technically speaking, it isn't your head that?s hurting. Did you know brain tissues and skull bones don?t have the nerve fibers that are sensitive to pain and therefore can?t generate the sensation of pain? So why does your head hurt with a migraine?
Migraine headaches have something to do with the blood vessels, that is why they are called vascular headaches. When you are experiencing migraine, your temporal artery is enlarged, which is located just under the skin at your temple. When this happens, it makes the tiny nerve fibers twisted around it to release chemicals.
The chemicals released cause pain, inflammation, and further enlargement of the temporal artery. The greater the swelling, the worse your pain becomes. So why does this artery enlarge to the point of causing severe pain?
The answer may lie in another naturally occurring chemical in the body. There are two major neurotransmitters in the brain that control blood vessel size, and one of them is Serotonin. Studies have shown that before a migraine occurs, there is a high level of serotonin. During the migraine, its level drops to an abnormally low level.
While the actual cause of migraines remains a mystery,
Ayurvedic View: According to Ayurvedic principles, migraine is a tridosha disorder,Out of the three doshas, Vata and pitta dosha are the prominent factors.
Vata controls the nervous system and brain activity and it is the imbalance of this Vata that causes the diseases. Vata imbalance arises due to improper metabolism, poor elimination, mental and physical stress, viewing of TV for long periods, reading with insufficient light, sleeplessness, etc.Out of the three doshas, pittadosha is the most prominent factor. "Pitta" causes dilation of the blood vessels, which causes the onset of a migraine attack.
