Florida summers bring more than just high temperatures—they also bring high humidity. Together, heat and humidity can make it much harder for your body to cool itself, increasing the risk of heat-related illnesses.
Normally, your body cools down by sweating. As sweat evaporates, it removes heat from your skin. But when the air is very humid, sweat doesn’t evaporate as easily. Instead, it stays on your skin, making it harder for your body to release heat. That’s why a 92°F day with high humidity can feel much hotter and be more dangerous than a drier day at the same temperature. The National Weather Service measures this combined effect using the heat index, often called the “feels like” temperature.
To protect yourself, drink water throughout the day—even before you feel thirsty. Avoid excessive alcohol and sugary drinks, which can contribute to dehydration. Wear lightweight, loose-fitting, light-colored clothing, and try to schedule outdoor activities during the cooler morning or evening hours. If you must be outside, take frequent breaks in the shade or an air-conditioned space.
If your home does not have air conditioning or loses power during severe weather, spend time in air-conditioned locations such as libraries, shopping centers, community centers, or designated cooling centers. Even a few hours in a cool environment can help lower your body temperature.
Know the signs of heat-related illness. Heat exhaustion can cause heavy sweating, dizziness, headache, nausea, weakness, and cool, clammy skin. Move to a cooler place, drink water, and rest. Heat stroke is a medical emergency. Symptoms include confusion, slurred speech, a body temperature above 103°F, hot skin, seizures, or loss of consciousness. Call 911 immediately if someone shows signs of heat stroke.
Finally, check on older adults, neighbors, and anyone who may not have access to air conditioning. During periods of extreme heat and humidity, a simple phone call or visit can help protect someone from a life-threatening emergency.
