Any exercise induces the body’s pituitary gland to release endorphins. There are 4 different types of endorphins – alpha, beta, gamma and sigma. It is found that during prolonged exercise sessions, acidosis of the blood occurs, which is indicated by decrease in the blood flow and oxygen to the muscle tissues. This triggers the release of beta-endorphins, as a response to tackle the anticipated pain or stress. These beta-endorphins have analgesic properties and raise the bar for the body in tackling migraine pains.
Similarly, another polypeptide, the enkephalin, is released by the thalamus of the brain during periods of exercise. They have the specific capacity to block the neurotransmitter, Substance P, which is notorious in triggering migraines. Catecholamines are another substance, which is released in short periods of exerting exercises. They raise the density and secretion of serotonin mildly and help counter migraine pains to some extent.
