A friend of mine called me Friday from a gasoline station. "I couldn't lift my bike up, so I rolled it down the stairs," they said. "Then I found I was having trouble steering, so I stopped at this gas station. I bought food and water and sat down to eat it. I am having trouble getting up." They'd spent 90 minutes at Bikram yoga earlier in the day (that's the one you do in 105 degree heat), but it had been four hours before the bike ride.
My first thought: a stroke. My first utterance, "Hang on, I'll drive over and take you to the emergency room." The emergency room at John Muir Hospital in Walnut Creek is suburban, thank goodness, so Friday night was not a nightmare of gunshot wounds. In fact, there were only six of us in the waiting room, so it only took two hours to get into the emergency room and three hours to get out. My friend had an EKG and a batter of tests, which confirmed the snap diagnosis of the doctor--while, I say snap, he asked a LONG series of questions--dehydration. Complicated because some drugs make the effect of dehydration worse. Do yours? Find out?
It's insidious. My friend, by the way, was drinking water all day. Turns out water isn't enough. I knew that--when I went on the AIDS ride from SF to LA, the doctor reminded us every night that if you rode 100 miles a day, as we were doing, and only drank water, you could, literally, drown. (He also told us if you didn't get up at least once in the night to pee, you were dehyrdated. I got up every night). The reason: you don't just need to replace water, you need to replace electrolytes. In short, Gatorade, or some other power drink (preferably the low-sugar version).
I was told years ago that if you wait to drink until you're thirsty, you're already dehydrated.
Anyway, while we waited two hours for blood test results, they hooked my friend up to a bag of saline solution and we played electronic Scrabble on my iPhone--better than watching the Disney channel for two hours, for sure. We then went to Safeway and bought a dozen bottles of Gatorade. One before Bikram and one after, from now on.
Ironically, while shopping the next day at Safeway, I felt a little dizzy, so I grabbed a bottle of Powerade and drained it, explaining to the clerk, "of course I intend to pay for it!"
Bottom line: dehydration is nothing to fool around with. Drink, drink, and then drink some more.
