As emergency physicians, we don’t just treat the effects of extreme heat-related illnesses— we see their impact on our communities every day. With record-breaking temperatures sweeping much of the country, heat-related illness has become a growing public health concern. That’s why we’re taking it seriously —our goal is simple: protect lives by helping people understand just how dangerous heat can be.
According to the CDC, more than 2,000 people in the U.S. die from extreme heat each year, and tens of thousands more suffer heat-related illness severe enough to require emergency care.
This summer’s extreme heat has sent more than just temperatures soaring — it’s brought a steady rise in heat-related illnesses into emergency departments across the country. As an emergency physician, I know how quickly heat stroke can turn life-threatening, even in people who were just outside for a short time.
Most patients don’t realize they’re in danger until it’s too late. They may come in confused, dizzy, or light-headed. Others arrive unconscious. One of the defining signs of heat stroke is a high body temperature — often over 104°F — paired with altered mental status. Unlike heat exhaustion, these patients often stop sweating, which is a major red flag. In many cases, they were simply trying to get yard work done, walk to the store, or enjoy a summer outing.
When spending time outdoors, watch for the following. Signs of heat-related illness include:
- Elevated body temperature
- Lightheadedness
- Muscular cramping
- Nausea or vomiting
- Confusion
Heat stroke is normally treated aggressively and urgently – rapid cooling using ice packs, cold IV fluids, fans, and in some cases, specialized cooling blankets. Every minute counts — the longer a person’s core temperature remains elevated, the higher the risk of serious complications like kidney failure, brain damage, or even death.
The groups we worry most about are young children, older adults, and those with chronic illnesses. People who work outside, especially without adequate hydration or breaks, are also at elevated risk.
The good news? Heat stroke is preventable:
- Stay hydrated — don’t wait until you’re thirsty
- Avoid outdoor activity during peak heat hours (usually 10 a.m. to 4 p.m.)
- Wear light clothing and seeking shade frequently
- Check on vulnerable neighbors or relatives, especially during heat advisories
This summer has reminded us all that heat isn’t just uncomfortable — it can be dangerous. Knowing the signs of heat illness and acting early can truly save lives. From our perspective in the ER, we hope you stay cool, stay informed, and help spread the word.
