I had Covid in February 2021 during the "big freeze" in Texas. I didn't even know I was sick until I lost my ability to taste and smell. It wasn't until that summer that I realized I was unable to tolerate heat as well as I used to. I would be out mowing or doing my other ranch work and would have to stop because I would start feeling sick from the heat. I also noticed that when I would be sitting in the house watching TV, I would all of a sudden break into a sweat and then it would stop. I went to a gathering at a friend's house. It was in July 2021. The house was air conditioned and felt comfortable. After awhile, with all the people in the room, it became a little warm. I began feeling a little nauseous and ended up lying on the cool tile of the bathroom floor. I am still bothered by the heat. I even skipped the gathering today at my friend's house because I'm afraid of a repeat performance. It is much hotter this July than last year. For now, I try to tolerate the heat by wetting down overshirt and hat and keeping a wet kerchief around my neck before going out to do my chores. I keep plenty of water and sports drinks close by. I'm sitting at my desk writing this and just broke into a sweat. I haven't been running any fevers when it happens. It sure would be nice if this and the other long haul symptoms would disappear. I don't have time for this!
