Just a few hours of exercise a week could help reduce migraine triggers.

That’s according to a new study of more than 4,600 chronic migraine patients.

It showed that those who exercised for at least two and a half hours a week reported less stress, depression, and sleep problems, all of which trigger migraines.

In fact, half of the patients who did no exercise, had at least 25 headaches a month.

But only a quarter of those who worked out the most had that many migraines.
