My migraines are triggered by heat. It is a fact that I don't sweat like I should, and I feel this may be significant. However, none of the physicians I have seen ever seem to think this is relevant. There are many other triggers for my migraines, but the heat migraines are a definite headache. Any comments?
Heat is a very common Migraine trigger. Hydration is also a big trigger, so be sure to stay well hydrated, especially in hot weather. Sometimes, effective Migraine preventives help reduce even those Migraines triggered by heat, but many of us find that we have to do our best to avoid situations where we'll be in the heat.
Have you always had problems with not sweating enough, or could it be related to any medications you take? I know it's hard, but you need to find a doctor who will check this out. It can be quite harmful.
I believe heat can be a major trigger for migraine headaches, as some of the worst headaches I've ever had have come after prolonged exposure to heat. The worst headache I've ever experienced was last summer. My husband and I had been outside mulching a house that we were in the process of selling. The temperature was in the mid 90s, and we were outside for at least 2 hours. We both drank plenty of water. Towards the end of the job, I began to feel like I wasn't able to function. Everything seemed to slow down. I sat in the shade until my husband finished. As soon as we sat in his truck, I felt as though someone had hit me in the head with a 2 x 4. He took me home immediately and I took a Maxalt that had been prescribed. It didn't help and the headache and vomiting became worse, so I took another. I got so bad that I couldn't see, I couldn't stand, I could barely function. As if that wasn't bad enough, when the headache and vomiting finally subsided, I continued to feel weak for at least 3 or 4 days
