I’ve had migraines since I was a child, so by now I’ve learned how to live with them fairly well. My basic rule is simple: don’t do things that seem likely to bring on a headache, and stay away from the things that tend to trigger one.
For me, that means not staying in direct sunlight for too long, not overusing my eyes, not dressing too lightly in spring or autumn, and of course being careful not to drink too much. I also try to avoid certain smells. But none of those seemed to apply this time, and my head has been hurting since yesterday—!

I hadn’t done anything unusual. Today is better than yesterday, but there is still a dull ache. And the hardest part is when that faint, nagging pain just keeps going.
So I thought I’d write about it on the blog. When I searched online for “migraine,” one of the top related searches was “typhoon migraine”!!
What!? Can a typhoon really trigger a migraine?
According to what I read, “Sudden changes in air pressure and temperature caused by a typhoon can sometimes bring on headaches.” Sure enough, Typhoon No. 19 had passed directly over Osaka the day before. I knew from experience that all sorts of things could trigger a migraine, but I had never realized a typhoon might be one of them.
So now I have one more thing to watch out for: typhoons. If you get migraines, it is really tough.
