Headache specialists are still unraveling the mysteries of migraine and other headaches. Most believe a combination of factors, from genetics to neurovascular imbalances in the brain, play a role.
But what role could weather play? One leading evolutionary theory is that getting a headache is a protective mechanism against adverse environmental stressors. The theory goes that headache pain would cause someone to seek a safer, more hospitable environment. The fact that changes in weather and extremes in heat and cold cause headache, some experts believe, gives credence to this theory.
Migraines are so common, there's a special name for people who get a lot of them: migraineur. Yet, loved ones don't always understand the condition, and even if they do, serious headaches can put a strain on time with spouses, family, and at work.
You may not be able to cut migraines out of your life, but you can help others understand how they affect you. That way, everyone will know what to expect and how they can help you.
In a survey by the National Headache Foundation, headache sufferers were given a list of 16 possible triggers. They then were asked to rank them in terms of what commonly brought on their migraines and other headaches. Three out of every four respondents said that weather triggered their headache pain. Specific weather triggers include:
Changes in humidity
Changes in temperature
Extremely dry conditions
Listed below are common environmental triggers for headaches included in the survey and the percentage of people who identified them as triggers. People often have more than one type of trigger for their headaches. How many, if any, of these factors trigger your headaches?
Weather or barometric pressure changes: 73%
Intense odors: 64%
Bright or flickering lights: 59%
Extreme heat or cold: 38%
Altitude changes: 31%
High winds: 18%
Most of the participants reported that these environmental triggers have kept them from participating in their normal outdoor activities. They also said they'd stayed away from places likely to have smoke in the air, such as restaurants or bars.
Why Weather Triggers Headaches and Migraine Synptoms
As noted earlier, there is a theory that headaches triggered by extreme weather are a protective, or defensive, response because they lead the person to seek a more hospitable environment.
Experts believe that people who get frequent headaches have a greater sensitivity to changes in the environment. They also have a lower threshold to the pain response. The reason, they suspect, is that people who get migraine headaches have likely inherited this sensitivity.
The survey cited earlier also found that two out of three headache sufferers had not discussed environmental triggers with their doctors. Nearly half of them, though, had been plagued by headaches for more than 20 years.
