temperature changes do make the blood vessels change which effects headaches, mainly migraines. I use to use a little trick to get rid of a migraine quick in would go run really hot water over my scalp. then quickly switch it to ice cold and the sudden fluctuation on the scalp would make the blood vessels rapidly change and my headache would be gone. Sure it would come back eventually, but sometimes it was a nice reprieve while I waited for meds to kick in.
