Well, I finally found out what heat exhaustion is. Last night at work I got a good dose of it. This was the first time it ever hit me like this. It was hot yesterday,around 100 or so. Was sweating my butt off is the shop and thought i was drinking enough fluids. about 8pm it finally hit me like a ton of bricks. One of the car washers found me laying in the middle of the shop floor passed out. Don't remember going down, But I remember being sick on my stomach with cramps, headache, weak and dizzy(more then normal). really didn't pay much attention to it, just figured I was having a bad day. He called the local sort supervisor I think and a couple people started to get fluids in me and tend to me. She got me up and we walked to the diad room to sit in the A/C a little to cool down. I refused to go to the hospital to get checked out when she asked, figuring it wasn't that bad after i started to move around and get cooled down. She called my Automotive supervisor (who is a pretty good guy) and he came down around 9:30pm or so and checked my blood pressure, and made sure I was ok. I am still feeling the effects this morning. I can't remember ever being hit like this, usually deal with the heat pretty good, at least in the past, anyways. Maybe it has something to do with turning 40 this past year, hard to tell. I'm pretty sure we all know about dealing with the heat in general. Just becareful, specially you guys driving. When it hits, it hits hard. Pay attention to the signs if it is really hot out.
