Unraveling the Weather-Migraine Connection
Scientists are still figuring out the exact reasons why some people get migraines. It could be due to genes, changes in the brain, or alterations in the levels of brain chemicals. However, it’s known that certain things can trigger migraine attacks, such as certain foods, hormonal changes, and stress. Even the weather can play a role in causing migraines.
The connection between weather and migraines
According to a study in Taiwan from 2015, about half of people who suffer from migraines believe that changes in the weather can bring on their headaches.
Things like storms, extreme temperatures, and shifts in air pressure might cause migraines by affecting certain chemicals in the brain, such as serotonin.
Research on the link between migraines and weather is not straightforward because it’s challenging to study. Weather changes can lead to different reactions, making it difficult for researchers to pinpoint a single cause.
Moreover, not everyone reacts the same way to changes in weather. Some people may experience migraines when it’s hot, while others may get them when it’s cold. Additionally, certain individuals are more sensitive to variations in temperature and humidity.
Migraine triggers can also be a combination of factors. For instance, you might have a migraine on humid days, but only if you’re stressed or hungry.
Changes in humidity
The relationship between humidity, temperature, and migraines is not always straightforward. Generally, higher humidity and temperatures can trigger migraine attacks, and sudden changes in these conditions (either up or down) might also play a role.
A study in 2017 found that more people visit the emergency department for migraines on warm and humid days, while there is a decrease on cold, dry days. Another study in 2015 observed an increase in emergency room admissions for migraines on hot, dry days.
One possible explanation for the higher occurrence of migraines during hot or dry weather is dehydration, a known trigger for migraines.
