Cooling Centers Expand in US Cities but Struggle to Attract 2026

As extreme heat waves intensify across the United States, cities are expanding cooling centers to protect vulnerable populations, yet many lower-income residents still avoid these public air-conditioned spaces. Despite the increased availability of cooling centers, heat-related illnesses and deaths continue to rise, highlighting a critical gap in public health outreach.

Why Cooling Centers Are Underused

Cooling centers are designated public spaces, such as libraries, community centers, and recreation facilities, where people can escape dangerous heat. However, experts point to several barriers that keep people away, including long commutes, lack of awareness, and a perception that extreme heat is not an immediate threat. Lower-income individuals, who often lack reliable transportation or air conditioning at home, are especially at risk.

Transportation and Accessibility Challenges

Many cooling centers are not conveniently located near low-income neighborhoods, making it difficult for residents to reach them, especially during peak heat hours. Public transit may be unreliable or unaffordable, and walking long distances in extreme heat poses its own health risks. Cities must consider mobile cooling units or extended hours to bridge this gap.

Heat-Related Health Impacts on Vulnerable Populations

The health consequences of extreme heat are severe, particularly for the elderly, those with chronic conditions, and people experiencing homelessness. In New York City, emergency room visits for heat-related illnesses soared to 156 on July 3 when temperatures exceeded 100°F, the highest since 2017. Similarly, Maine saw 128 heat-related ER visits on July 4, and Maryland reported at least 38 heat-related deaths this summer—already surpassing last year's total.

Psychological and Social Barriers

David Giffen, executive director of the Coalition for the Homeless, explains that unsheltered individuals often possess resilience and survival skills that make them less likely to seek indoor refuge. "They don’t necessarily think, ‘Oh, now it’s getting hot, and I should finally come indoors,’" he says. This mindset, combined with distrust of institutions, creates a significant hurdle for outreach programs.

Comparing Urban Heat Response Strategies

Key Takeaways for Improving Cooling Center Utilization

• Place cooling centers in high-need areas with extended hours.
• Offer free transportation or shuttle services to and from centers.
• Use trusted community leaders and peer outreach to build confidence.
• Provide additional services like water, snacks, and medical check-ins.
• Implement real-time heat alerts via text and local media.

Innovative Solutions to Increase Cooling Center Attendance

Cities are experimenting with cooling buses, pop-up misting stations, and partnerships with local businesses to create more accessible relief points. For instance, some municipalities have transformed idle city vehicles into mobile cooling units that travel to vulnerable neighborhoods. Others are training volunteers to conduct door-to-door wellness checks during heat waves.

The Role of Public Awareness Campaigns

Effective communication is crucial. Many residents simply do not know where cooling centers are or how to access them. Cities must invest in multilingual, culturally sensitive campaigns that emphasize the dangers of heat and the benefits of cooling centers. Social media, community radio, and flyers at food banks can help spread the word. The background to this story is set out in Urban Heat Islands: How Smart Tree Planting Cools Cities.
