Summer has arrived, and with it comes the threat of heat-related illnesses as a major heat wave sweeps across the central and eastern U.S. in June 2025. While many people enjoy the summer season for outdoor activities like cookouts and beach trips, it’s important to be aware of the risks associated with high temperatures and humidity.
Heat-related illnesses can affect anyone, even those who appear healthy. Older adults and individuals in areas without air conditioning are particularly vulnerable during heat waves, as demonstrated by the tragic events in Chicago in 1995 when hundreds of people lost their lives due to extreme heat.
As a professor of public health specializing in climate change and health risks, I have seen the growing concern surrounding heat-related illnesses. Recognizing the warning signs and taking appropriate action is crucial when temperatures rise.
Heat-related illnesses range from mild conditions like heat cramps and heat rash to more serious conditions like heat exhaustion and heat stroke. It’s essential to recognize the symptoms and take steps to cool down and stay hydrated to prevent these illnesses from escalating.
Monitoring the heat index, which factors in temperature and humidity, can help determine the level of risk for heat-related illnesses. It’s important to avoid strenuous outdoor activities in high temperatures, stay hydrated, and seek shelter in air-conditioned spaces during the hottest hours of the day.
For older adults and vulnerable populations, communities can provide support by offering cooling centers, bottled water, and regular wellness checks during heat waves. By taking precautions and looking out for one another, we can all stay safe and enjoy the summer season.
Remember to stay hydrated, avoid excessive physical exertion in high temperatures, and seek medical help if you or someone you know shows signs of heat-related illness. Let’s make the most of summer while staying safe and healthy.
