When summer temperatures soar, your body can go from hot to overheated in minutes, especially during outdoor activities. Heat stroke is the most dangerous heat-related illness. It’s more than just overheating—it's when your body temperature rises to a life-threatening level and your cooling system shuts down. Quick action is critical. Warning signs to watch out for are: - Hot, dry skin — with little or no sweating - Confusion, dizziness or slurred speech - A rapid, strong pulse - Vomiting, seizures or passing out If you see any of these signs: - Call 911 right away. - Move the person to a cooler place — in the shade or indoors. - Remove excess clothing. - Start cooling the person with cold, wet cloths, ice packs on the neck and underarms, or even a cold bath if you can. Heat stroke can cause permanent damage—or worse—if not treated quickly. Know the warning signs and stay alert to protect yourself and those you care about.
