I am very prone to heat exhaustion. It started when I was about ten, and has gotten worse every year. (I'm sixteen now) Often when I'm in a hot environment, (about 75 degrees and above) and especially if I'm riding, I get this...fuzzy feeling in my head. Then I feel nauseous, and my vision goes dark. Kind of like when you stand up too fast. That weird, light-headed-and-practically-blind thing. It is a very unpleasant experience.
It happened in my riding lesson this afternoon. (well, yesterday actually, haha :P) It was about 88 degrees and sunny, so I told my instructor we had to keep it short. So, I drank a glass of water, slathered on my SPF 100 (XD) and headed out.
After about 20 minutes of light work, I started feeling minor symptoms. I stopped my lesson, and figured I'd be OK. Usually if I listen to my body and don't push it I'm alright. But this time was different. After I dismounted it just got worse, and I had to have my instructor untack my horse while I sat in the shady corner of the arena. I wasn't sure I'd be able to walk without collapsing or fainting. After several minutes I had my instructor help me to the barn, where I laid in front of one of the gigantic fans. I stayed there for about 20 minutes, and by then I felt OK enough to sit up. It took me several hours to fully recover.
Now, since I do NOT want a repeat of that, I've been thinking. I have low blood pressure, so could that be a factor? And, for awhile I thought it could be dehydration, but that doesn't seem right. I drink water and gatorade before, during, and after my rides. I don't know what is wrong with me. No one else I know has this problem, at least not to this extent.
I try to ride in the mornings and evenings, but often that just isn't possible. I'm usually forced to ride right during the heat of the day.
Does anyone else have this problem? And if so, have you figured out how to deal with it? It gets so hot here in the summer, and the heat consistently cuts my rides in half, if not more. I'm also worried about shows, since they are almost always outside and during the afternoon. At this point a show would be out of the question.
So, if anyone can help, that would be amazing!
Sorry this is so long. :O
