What are Dehydration and Sunstroke?
Dehydration is a decrease in the body’s water balance. Water is crucial for survival since approximately 75 percent of the human body is water, so dehydration can have severe health consequences. Proper hydration is particularly important in hot weather to help lower the risk of heat-related illnesses like heat exhaustion and sunstroke.
Sunstroke, or heat stroke, occurs when the body loses its ability to cool itself and body temperature rises above 104 degrees Fahrenheit. Certain groups of people including infants, young children and older adults, as well as those taking certain medications or with certain health conditions, are more prone to these conditions.
