SUN EXPOSURE

Dehydration is a common but easily preventable condition brought on in the backcountry by strenuous exertion. Dehydration occurs when your body loses too much fluid and you don’t drink enough to sufficiently replace that lost fluid. Symptoms can include muscle cramps and lightheadedness. Not properly rehydrating can lead to severe dehydration, which will eventually become a life-threatening condition. While on the trail, make sure to drink plenty of fluids and you shouldn’t have to worry about becoming dehydrated.

Heat exhaustion and heatstroke (sunstroke) are not-uncommon afflictions in the backcountry of sunny Northern California. Heat exhaustion occurs when the rate of perspiration is insufficient to cool the body. This condition can develop when a person exercises strenuously in hot weather and does not drink enough fluids to replace those lost through perspiration. Symptoms include flushed skin, rapid breathing, and possible fainting. Drinking plenty of water or an electrolyte-replacement beverage (such as Gatorade) will prevent heat exhaustion. Moderate to severe heat exhaustion can lead to heatstroke, in which the body is unable to regulate core temperature and that temperature continues to rise—simply put, the body produces more heat than it can lose. The symptoms include pale but hot skin, rapid heart rate, mental confusion, convulsions, and unconsciousness.
