Recognize and Respond to Heat Illness

Heat-related illness and death are preventable, yet extreme heat continues to claim lives each year. Vulnerable groups—including infants, young children, pregnant individuals, and those with chronic medical conditions—face heightened risks due to reduced ability to regulate body temperature. Outdoor workers, athletes and DIY enthusiasts are especially prone to dehydration and heat stress. While outdoor activity offers health benefits, it's crucial to recognize warning signs. If you feel faint or weak, stop immediately and move to a cool environment.

Heat Exhaustion

• Symptoms: faintness or dizziness, heavy sweating, fast and weak pulse, nausea or vomiting, cold and clammy skin, and muscle cramps. Sip water and move to a cooler place immediately.
• Action: Move to a cool place, hydrate, and apply cool wet towels. If vomiting persists, seek medical attention.

Heat Stroke (Medical Emergency)

• Symptoms: a high body temperature (above 103°F), red or hot skin, rapid pulse, headache, nausea, and possible loss of consciousness.
• Action: Do not give fluids. Call 911 immediately, move the person to a cooler place, and lower their body temperature with cool cloths or a cool bath (do not immerse in cold or ice water—this can cause shock).
