    You don’t even have to exert yourself very much if the weather is already very hot and humid. I passed out during a fairly easy hike back in 1988, when my area was experiencing 105°F or higher heat index — but I didn’t know that when I set off. I was fortunate that I succumbed to the heat in a shady spot, or I might not be here to tell you about it now. As it was, I was unconscious for 2-3 hours, and felt very off for the next couple of days after overheating myself so badly.

    Thank you! Denatured proteins was the bit I was needing to understand. Previously I understood the symptoms and treatment from seeing it in others and from experiencing it.

    Worst pain ever, I remember one time, it was like 46°C and I was practicing horse riding, when I got down I was so nauseous and dizzy, I was seeing everything yellow, I felt my heart beating so strong that it was about to explode, I couldn’t talk or move, I really thought I would die cause no one was noticing me, fortunately, my dad was there so he gave me some water, and I started feeling better, thanks dad

  38. California Doll on October 15, 2021 at 9:28 am

    I had Heat Stroke once, In Arizona I was laying out at the age of 27 sunbathing, it was 111F outside, after about 40 minutes I couldn’t take it. It was to hot, it was hard to breathe, i was getting so nauseas and dizzy. I started walking back inside which is about a 30 feet walk and I swear I about fainted going in, if the walk back would’ve been maybe 32-34 feet I really do think I would had collapsed and died outside with noone to have noticed it. So scary

    In the fifth grade, during graduation practice, one of the kids got heatstroke (but was conscious) so they went into the cafeteria and got him grape juice. This was all indoors, too. We were just standing on the bleachers and rehearsing when it happened

  47. Shubhrajit on October 15, 2021 at 9:41 am

    This happened with me two times while travelling on the bus during the summer months last year. It drove me unconscious!

  48. Woody boy on October 15, 2021 at 9:42 am

    When I was younger I stayed the night at my cousins we played all day and it was like 100 out I fell asleep under a window that was open under a big blanket I’m telling you it’s no joke I was at the mercy of other people I could not move I couldn’t even move my fingers I couldn’t drink water felt like vomiting it up I was seeing people that weren’t there people told me I said there was kids around the bed and they have presents and wanted me to go play with them but they kept telling me not to go play with the kids I remember it was dark and stormy but everyone told me it was a bright sunny day there was no storm the worst headache I’ve ever had to this date.
