Just thought I’d share my personal experience:
I had heat-induced hives for a couple of years. I’d get it about 5 minutes into jogging. It would last for a few minutes then disappear – nothing severe but annoying to the point that sometimes I’d stop jogging. I would also get symptoms in a hot shower, sauna, etc.
I quit smoking about 8 months ago and it hasn’t happened at all. Smoking could very well have been the cause.
All the best to those with the condition.
