Hot Weather A Migraine 'trigger'

[Coast]

A hot day can spell bad news for migraine sufferers, increasing their risk of an attack the next day, US research suggests. The risk went up by 7.5% for every five degree Celsius increase in temperature revealed the study of more than 7,000 patients, published in Neurology.

Lower barometric air pressure, which typically brings cloudy or stormy skies, within two or three days leading up to a person's hospital visit also increased headache risk. Air pollution had no effect.

Do weather conditions affect you if you suffer from migraines?

My worst ever migraine ( I lost a whole afternoon as I passed out from the pain) was during the really bad heatwave approx 4? years ago but I suspect I also got dehydrated due to the heat and dehydration brings them on too.

Stormy weather and low pressure certainly trigger my headaches, I think quite a few people have posted about that before.

Headaches in general are to do with the muscle contraction around the scalp, so given I imagine in hot weather the scalp muscles have to contract to allow of increased blood flow to the brain, so it's not surprising. I imagine cold weather would also cause headaches (maybe even migraines) because the muscles are tensed so much due trying to keep warm.

I used to suffer with migraines but no longer, and never attributed them to the weather. In fact as trips to both hotter and colder areas of the world have increased for me, so the number of headaches have decreased.

Mine were brought on by strip lighting it was discovered. (unscientifically)
