I suppose I would attribute it to being overheated when I was a teen while working outside in 100 degree temperatures. It was bad enough that I broke into a cold sweat and was cold in the hot sun, and also had flu like symptoms for a week after. When a Sunday school class member ended up in the hospital from dehydration.
If you don't believe it can happen to you, my buddy is a desk jockey who doesn't go outside and stays in an air conditioned environment over 90% of his life yet he still ended up with his life in danger on a stretcher in the emergency room from low fluid intake.
In discussion with the class I found that I am a bit more aware than most people concerning fluid intake and output. For instance I as soon as I wake up I drink 30 to 40 ounces of water to begin my day. I try not to drink anything other than water if I am working or going to be out on a hot day, and I note the color of my urine when I go to the bathroom and adjust my fluid intake as needed.
clear - over hydrated
light yellow - normal
dark yellow - slightly dehydrated
orange - moderately dehydrated
I already know I'm weird, but has anyone else been dehydrated to the point that you require medical attention, and did it cause you to be more aware thereafter?
