While the exact cause of exercise-induced migraines isn't totally understood, it could be a chemical change in the brain, especially among those who are out of shape, or it could be that the very early stages of the attack have already begun, meaning the nervous system might be extra sensitive, she explains.The good news is that regularly breaking a sweat can often be a successful way to reduce the number of migraine attacks you experience. "If you exercise on a regular basis, the body makes its own painkillers," Silberstein says. (Even better, one study published earlier this year found that sex can relieve migraine pain for some people.)If the impact that comes with some exercise seems to be the problem, Buse suggests trying swimming, biking or yoga instead. ”
