I got heat stroke around 30 years ago when I use to do landscaping. It was crazy, basically I cooked like a hotdog and passed out and it took forever to get back to normal. Passing stools was like passing bricks, it hurt like hell and did some permanent damage. My doctor was worried I did some damage to my liver and kidneys but 30 years later I’m still here. That was our bastard boss who demanded we work no matter what. “Oh its 110 degrees out, yes perfectly fine to do some hard labor digging trees out”
Once you’ve had one heat stoke you are likely to have another if you are not careful. The first one somehow changes your body making you susceptible to another. I used to do manual labor in Texas north of Houston. Hot as hell but I drank lots and lots of water. I made sure I never stopped sweating. Stopping sweating is a early warning that a heat stroke is coming and that it’s time to take a break and pour water on yourself.
