Chinook season is approaching and with that, warm winds and migraines.

Despite the evidence that weather changes can cause headaches and other pains, researchers still don't have an explanation.

"Patients tell us a lot that Chinooks and weather changes in general have a big effect on headaches but I don't think we've really gotten to a point where we understand why," says Lori Montgomery, Medical Director of the Chronic Pain Centre.

"It happens not just for headaches, it happens for all kinds of pain conditions."

Montgomery says there isn't just one trigger that sets off a migraine. People who are not getting enough sleep, have changed their diet or skip breakfast may be more prone to headaches or migraines when the weather changes.

"Part of it is genetic and then part of it is those triggers that you stack up," she says, adding that getting enough sleep and having a healthy diet can be key for preventing headaches.

Montgomery says that old injuries can also flair up and cause pain during weather changes but there isn't a know reason for that either.

If you suffer from frequent headaches, the Chronic Health Centre offers seminars at South Health Campus in Calgary to learn more about what you can do at home to manage your pain.
