Yet another study finds that exercise is as good for the prevention of migraines as drugs. The research report in journal Cephalalgia by Swedish doctors shows that 40 minutes of exercise three times a week was as effective as taking topiramate (Topamax) or doing relaxation exercises. Topiramate is one of the most popular drugs for the prevention of migraine headaches, but it can have many potential serious side effects, including kidney stones in 20% of patients, glaucoma, memory and other cognitive problems. The same group of researcher published a large study of over 46,648 Swedes which showed a strong inverse correlation between exercise and any type of headaches, including migraines. So, before resorting to drugs or even Botox injections it is worth trying a regimen of avoiding triggers such caffeine, adhering to a regular sleep schedule, taking magnesium and other supplements, and regular exercise.
