TL;DR
The CDC has confirmed a significant increase in heat-related emergency department visits across the U.S., emphasizing the health risks posed by recent heat waves. This surge highlights the need for increased public health awareness and preparedness.
The Centers for Disease Control and Prevention (CDC) has confirmed an ‘extremely high’ increase in heat-related emergency department visits across the United States, as heat waves continue to grip many regions. This development underscores the growing health risks associated with extreme heat and the urgent need for public health interventions.
According to the CDC, the rate of emergency department visits related to heat exposure has surged significantly in recent weeks, with some areas experiencing levels that surpass previous records. The data, collected from national health surveillance systems, indicates that over 200,000 heat-related visits have been recorded in the past month alone, representing a marked increase compared to the same period last year.
Health officials attribute this spike to the ongoing heat waves affecting large parts of the country, with temperatures frequently exceeding 100°F (38°C). The CDC emphasized that vulnerable populations — including the elderly, outdoor workers, and those with chronic health conditions — are disproportionately affected. The agency also warned that heat-related illnesses can escalate rapidly, leading to heat exhaustion, heat stroke, and even death if not promptly treated.
While the CDC’s report is based on confirmed emergency department data, it also highlights the potential for underreporting and the need for ongoing surveillance to fully understand the scope of the health impact caused by extreme heat.
This surge in heat-related emergency visits is a clear warning about the increasing health risks posed by climate change and more frequent heat waves. It underscores the importance of public health preparedness, community awareness, and individual precautions to prevent heat-related illnesses. The data also signals a need for policymakers to prioritize heat mitigation strategies and support vulnerable populations who are most at risk.
Healthcare systems may face additional strain as more patients seek urgent care related to heat exposure, potentially impacting hospital resources. The CDC’s findings serve as a call to action for both health authorities and communities to implement effective heat response measures.

Over the past decade, climate scientists have documented a steady increase in the frequency and intensity of heat waves across the U.S. and globally. Public health agencies have previously issued warnings about rising heat-related illnesses, but recent data from the CDC confirms that the situation is worsening. In 2022, the CDC reported a notable rise in heat-related emergency visits, and current data suggests this trend is accelerating amid the ongoing heat waves of 2023.
Historically, heat-related illnesses have been seasonal, but the current patterns show an extended period of extreme temperatures, which exacerbates health risks. Urban heat islands, socioeconomic disparities, and lack of access to cooling resources further compound the problem, especially in densely populated and underserved communities.
Prior to this CDC report, some local health departments had observed increased hospital visits related to heat, but the national scale and severity of the recent spike are now confirmed by CDC data, marking a significant concern for public health officials.
“The rise in heat-related emergency visits is alarming and highlights the urgent need for communities to implement heat safety measures.”
— CDC Director Dr. Rochelle Walensky

It is not yet clear how long the current surge in heat-related emergency visits will persist or whether it will stabilize as temperatures fluctuate. Ongoing surveillance is needed to determine if this is a temporary spike or part of a longer-term trend driven by climate change.
Further data is also required to understand regional disparities, the effectiveness of public health interventions, and the impact of community cooling resources on reducing hospital visits.

Next Steps for Public Health and Policy Responses
Health authorities are expected to enhance public awareness campaigns about heat safety and expand access to cooling centers, especially in vulnerable communities. The CDC and local agencies will continue monitoring heat-related health data to identify emerging trends and inform policy decisions.
Researchers will analyze the effectiveness of recent interventions and explore long-term strategies to mitigate heat-related health risks amid ongoing climate change. Expect updates on regional case numbers, hospital capacity, and public health advisories in the coming weeks.

Key Questions
What are the main health risks associated with extreme heat?
Heat-related illnesses include heat exhaustion, heat stroke, dehydration, and can lead to organ damage or death if untreated. Vulnerable groups are at higher risk.
How can individuals protect themselves during heat waves?
Stay hydrated, wear lightweight clothing, avoid outdoor activities during peak heat, use fans or air conditioning, and seek shade or cooling centers if needed.
Healthcare providers report increased admissions for heat-related conditions, which may strain hospital resources in affected areas, but specific capacity impacts are still being assessed.
What measures are public health officials recommending?
Officials advise public awareness campaigns, opening cooling centers, providing resources for vulnerable populations, and long-term climate mitigation efforts.
Will this trend continue or worsen?
While current data confirms a spike, it remains uncertain whether this will persist. Ongoing monitoring and climate projections suggest the risk will likely increase if climate change continues unchecked.
