Yes, definitely. When I get too hot I have what I think of as a pretend relapse. The usual symptoms, just for a day.
I used to be mad for sauna, now I can't go any more. Last time I went I slept all afternoon afterwards, weak as a newborn kitten.
I try not to get too hot, but this week we had a heat wave here in Southern Germany, well over 35C. Nothing you can do about it, since we don't have AC in the house or at the office. So yesterday I was wobbling all over, knocking stuff over, and could not speak German - strange, cause normally I can. But today it is just 30C and I'm fine again. I have a ventilator here on my desk, a real life saver. And before I go to bed I have a lukewarm shower and hop into bed still wet, gets me to sleep, but I wake up when I warm up again, despite open doors and windows.
Sunday was so hot I just sat under a tree all day, drinking water and doing Sudoku. Actually very pleasant.
