I have long been an advocate of proper hydration. You know, drink water…lots of water…all day, every day.
So, imagine my  surprise when I looked back on a day last week and realized I was so dehydrated that I was actually suffering from heat exhaution.
We were traveling about 8 hours on the un-airconditioned bus to cross the border between Panama and Costa Rica.  All day, sitting on the bus with a brief stop to get passports stamped, walk a half a kilometer from one country to the other, get another stamp and reboard.
Over the course of the day, I drank about a liter and a half of water. I figured that should be sufficient.
I figured wrong.
By the time I staggered off the bus at the end of the day, I felt lightheaded and confused. Steve said my face was red and, despite the heat, I was not sweating.
Heat exhaustion and dehydration.
A liter of water later and half an hour staring  into the face of a fan, and I was feeling more level headed. For the rest of the day, I just kept drinking water, trying to help my body return to normal.
Heat exhaustion can lead to heat stroke. That can land you in the hospital.
When you’re traveling, especially in the tropics, don’t slow your intake of water because you are less active.
TO PREVENT HEAT EXHAUSTION
-Wear loose-fitting, lightweight, light colored clothing
-Drink lots of water
-Avoid alcohol
-Stay in the shade as much as possible (make your own shade if necessary: put a towel or shirt over the bus window if you can, for example)
-If you are taking medications for high blood pressure or certain anti-depressants, know that these can make you more prone to heat-related illnesses and dehydration. Check with your doctor or pharmacist to see if you need to be even more careful.
IF YOU BECOME DEHYDRATED AND HAVE
SYMPTOMS OF HEAT EXHAUSTION

-Get into a cool place as quickly as possible
-Drink lots of water
-Use a wet cloth to cool your head and face
-Loosen your clothes and take off anything that you don’t need to wear
-Relax
