“Drinking too much water nearly killed me!”
That’s how the story started on a first-aid course I was teaching. I was into the middle of my spiel on hyponatremia (water intoxication) when one of the students blurted out that statement.
“It occurred on an organized long distance bike ride,” he continued. “We were riding along a ridge and I started to feel sick and was developing a headache. I thought I was just dehydrated and needed to rest, so I drank more water, but the headache was getting worse. I knew something was wrong and needed to go to the hospital. Luckily I wasn’t alone on the ride and an aid station was near by.
