Physicians Warn of Heat Illness Risks as Triple-Digit Temperatures Persist

With Coachella Valley temperatures exceeding 110 degrees for the rest of the workweek, concerns over heat-related illnesses are rising—especially among older residents. According to the Riverside County Department of Public Health, nearly 180 patients were treated for heat-related conditions in 2023. Physicians emphasize that as people age, their bodies become less able to regulate extreme temperatures, increasing the risk for serious complications like heat exhaustion or heat stroke.

Dr. Alex McDonald with Kaiser Permanente explains that heat exhaustion symptoms include fatigue, dizziness, and headaches. If not addressed, it can escalate into heat stroke—a life-threatening emergency marked by confusion, vomiting, dry skin, and a rapid heart rate. “In that situation, we always tell people to call 911,” McDonald said.

Local triathlete William Calarese says he remains vigilant when training outdoors, staying hydrated and wearing sun-protective clothing. Still, he admits the heat can strike unexpectedly. “You have to really be careful and watch out for those signs,” he said.

Physicians recommend avoiding outdoor activity between 10 a.m. and 4 p.m., and heading indoors to cool off when necessary. Staff at public pools like Fritz Burns Pool are trained to respond to heat emergencies, adding another layer of safety for those braving the heat.
