In recent years, excessive heat has caused more deaths than all other weather events, including floods,. Our bodies lose water and salt when we perspire, which can lead to heat cramps. If not addressed, dehydration can lead to heat exhaustion. Heat exhaustion leads to heatstroke, a potentially life-threatening condition.
Young children, the elderly, and people with chronic diseases are most at risk of developing heat cramps, heat exhaustion, or heatstroke. Do you know how to lower your risk of heat-related illness…would you recognize the warning signs, and would you know what to do should heat-related illness strike?
