Drink a lot of liquids, and take extra salt. Wear cotton clothing, as its natural fibers breathe better than those of nylon and other synthetics. Wear a light-colored straw or cotton hat. For an exhilarating treat, dip the top of your head in a stream and let the cool water run down your face when you stand up. Sometimes it feels good and helps to soak a bandana handkerchief in a stream and wrap it loosely around your neck. Try washing your hands and arms to the elbows with water; even soaking your feet for a few minutes will help. I like to soak my hat in a creek, fill it with water and dump it on top of my head as I put my hat on. (See Fatigue).
