Heat Exhaustion and Heat Stroke

In most parts of the world, even where temperatures are relatively mild during spring or fall, it’s common to have a false sense of security in what is worn during a trip across country on foot. Unexpected changes in weather, unforeseen obstacles, or an unplanned overnight stay may have you wishing you had worn or brought along different clothing. During mid-summer when weather is relatively constant, the need for adequate clothing may become more obvious. When choosing clothing for a trek, you must account for distance, time, and terrain. While you may be comfortable when sitting and planning your course, forces immediately start generating heat in and around the body as soon as you actually start moving. Long journeys over tough terrain, or steep climbs during mild or hot days, can lead to heat exhaustion and even heat stroke.

When planning a day trip, you may want to start out on cold mornings by layering clothing. This can save time and make it easier to adjust by simply removing layers as the body and daytime temperatures begin to warm. Always adjust your clothing immediately when you feel your body warm; never wait until your body begins to sweat. Sweat is the natural result of the body attempting to cool itself, and while it is a good thing, the process takes away the body’s moisture. Sweat can lead to dehydration, which in turn reduces your body’s ability to sweat.

Along with dehydration, alcohol use will hinder your ability to sweat, affecting your body’s attempts to maintain a proper core temperature. Overdressing and wearing clothes that don’t allow your body sweat to evaporate easily may lead to heat exhaustion.
