That seems to fit eerily well with my experience. I most likely have an autoimmune condition, and, whenever I am sufficiently active to the point where I feel the adrenaline going, afterward I feel feverish and have a malaise.

I hope they do this research posthaste. I think I can personally benefit.
I wonder if there is any connection with the "shock" of jumping into a cold shower and the electro shock therapy detailed in the article.
