Elias Malek (Integrated Health Sciences), James Navalta, and Graham McGinnis (both Kinesiology and Nutrition Sciences) published a Pilot Clinical Trial in the International Journal of Environmental Research and Public Health (IJERPH). In this study, participants with chronic migraine exercised for a month either in the morning (before 9 a.m.) or evening (after 7 p.m.) in a randomized cross-over design. It was found that exercise only reduced migraines if it was performed at a time that was synchronous with a person's chronotype (i.e. their preference for mornings or evenings). These findings could be used to more accurately prescribe exercise to reduce migraine load in people with chronic migraine.
