Could the Weather Be Causing My Headaches?

For headache sufferers, the unpredictability of summertime weather can do more than ruin outdoor plans - it can trigger a migraine. Migraine-prone individuals are known to be more sensitive to external factors like diet, light and stress, but research suggests that heat also has an impact.

Migraines are severe throbbing headaches that affect over 36 million Americans that are typically triggered by certain external stimuli – foods, aromas/smells, bright lights or a change in the environment. As such, a spike in temperature is a common culprit for bringing on migraine headaches.

Studies have generally found higher rates of migraine in warmer seasons, and in one study with over 7,000 patients, researchers found that higher temperature and, to a lesser degree, lower barometric pressure led to an increase in risk of a headache requiring frequent emergency department evaluations.

Summertime can lead to migraines for a variety of reasons, the primary being that migraine sufferers are simply more sensitive than other individuals, so hot weather poses a high risk of triggering headaches. For example, the extended, bright sunlight that comes with a hot day can be a trigger, as can a change in the atmospheric pressure.

Since afternoon storms are an almost daily occurrence during Louisiana summers, this can be a particularly significant problem.

Medical research does offer hope that migraine sufferers can prevent headaches by being proactive.

To enjoy summer activities while avoiding migraine headaches, I offer these tips to patients:

  • Avoid caffeinated beverages as they tend to cause dehydration. Stick to plain water. Eating a salty snack with water helps in rapid rehydration.
  • Run errands and exercise in the cooler morning or evening hours
  • Apply cold packs to the head and/or neck
  • Stay hydrated with cool beverages
  • Wear sunglasses and avoid glare
  • Keep a "headache diary" for several days to determine what usually causes your headaches
