Extreme heat.
I’m unable to breathe or think correctly when my body overheats. It’s one of the most unbearable conditions for me to live with. Exhaustion settles over me as well, making me the most uncomfortable human being on the planet, to me anyways.
It also makes for the worst time for me to engage in conversation with anyone because I have the most difficult time listening to someone speaking. To me, when I’m overheated and one is talking, it sounds like the voice from the Charlie Brown cartoon, for those who are able to relate.
That sounds absolutely miserable. So sorry you have to go through that.
