Heat stroke is SERIOUS.
In 1980 I had all of your symptoms and then….
The next thing you'll experience is major cramps, severe trembling, collapse of muscle control, tunnel vision, folks telling you to "Stay awake!, Stay with me!" as other officers load you into your partners patrol car, the code 3 ride to the hospital, auditory exclusion, a vision of the Daily Oklahoman newspaper headline that morning "HUNDREDS DIE IN HEAT WAVE ACROSS THE NATION", recognizing you are dying and deciding to fight it, blackout, then comes the out-of-body experience as you float above the ER staff trying to revive you, you notice the pain is gone, a nurse calling out your temp at 107 degrees, collapsed veins from dehydration which results in trouble for staff trying to start an IV, chest compressions while you watch from the ceiling and say to yourself "Man, You look REALLY bad. I hope you come out of this." aaaand after several minutes, moving from the ceiling back to the ER gurney faster than anything you could imagine, opening your eyes and looking at the ceiling thinking "How did I get over HERE?!, 'cause I was just over THERE!"; a nurse says "He's back!", the pain hits like a freight train , then 24 hours in ICU as your heartbeat is tachycardia influenced and you slowly regain the ability to speak and when nurses and doctors come in the next day to check on you, you can recognize them from the ER and can tell each of them which side of your body they were on, what they did and what they said to other staff who were trying to revive you.
They look at you and say "THERE'S NO WAY YOU COULD KNOW THAT. YOU WERE UNCONSCIOUS!" And you tell them you were way past that, you were on the ceiling, watching everything.
THAT is my heat stroke story.
I learned to stay hydrated, keep my potassium up and went to midnight shift when it was still 95 degrees at 3 AM….

I don't like hot weather ever since then….
