Rising Temperatures Pose Health Risks: Expert Insights on Heat and Health
The scorching summer heat not only brings discomfort but can also lead to serious health issues, according to experts. Robert Davis, a professor of environmental sciences at UVA, emphasizes that high temperatures can result in the formation of ground-level ozone, a potential trigger for respiratory difficulties, especially for individuals with asthma or other lung-related conditions.
Highlighting the impact of extreme heat, Robert Davis shared insights with UVA Today back in 2025, linking such conditions to increased hospital visits, heightened mortality rates, and overall health deterioration.
Dr. Chris Holstege, who has extensive experience in emergency medicine and pediatrics, has observed these health surges first-hand. As the senior associate vice president of UVA’s Department of Student Health and Wellness, Holstege warns that heat can affect anyone, regardless of their baseline health.
“I have seen young, healthy people present with heat stroke, not just those who had risk factors for developing the spectrum of heat-related illness,” Holstege explained. “Heat-related illness is insidious and can be devastating to the body. Avoiding being outside in such elevated temperatures is the most important prevention effort.”
UVA officials recommend simple strategies to combat the heat: stay hydrated with water while minimizing alcohol and caffeine consumption, opt for lightweight and light-colored clothing, and take breaks in shaded areas when outdoors.
Recognizing the symptoms of heat-related sickness is crucial. Holstege advises, “The most important aspect is to get a person who is experiencing signs of a heat-related illness into a cool environment. Early signs can involve such complaints as muscle cramps, nausea, vomiting, headaches and passing out. Altered mental status (confusion) should prompt immediate evaluation in the emergency department.”
