Harris County Report Highlights Growing Risks of Excessive Heat and Heat-Related Illnesses
Harris County Public Health (HCPH) has released its 2024 Health Impacts of Excessive Heat in Harris County report, providing a comprehensive analysis of the escalating risks posed by extreme heat events. The report highlights how rising temperatures are increasingly affecting the health of county residents, with a dramatic surge in heat-related illnesses over the past few years.
According to the report, Harris County's average temperature has increased by 0.70 to 0.75°F per decade since 1975. Over the same period, heat-related illnesses have surged by 329% between 2019 and 2023. The report highlights that the majority of these illnesses occurred on the hottest days, with a heat index reaching 103°F or higher—a threshold defined by the National Weather Service as the point at which heat becomes dangerous and can lead to heat-related disorders such as heat exhaustion or heat stroke.
Vulnerable Populations Are Most Affected
The report emphasizes that extreme heat poses a disproportionate risk to vulnerable populations, including outdoor workers, children, older adults, and those with preexisting health conditions. Dr. Ericka Brown, Local Health Authority for HCPH, expressed concern over the growing public health implications. “The rising temperatures and more frequent heatwaves are not just environmental challenges; they are urgent public health issues that significantly affect our most at-risk community members,” said Dr. Brown. “Hopefully, this report will be a critical tool for all of us to take meaningful steps toward protecting our community and reducing health disparities.”
In particular, the report found that 14% of heat-related illnesses were job-related, with nearly half (48%) of these cases affecting Hispanic or Latino workers. Heat-related illnesses also disproportionately impacted individuals aged 18 to 44, who accounted for 47% of all cases. When broken down by race and ethnicity, Hispanic or Latino residents made up 33% of heat-related illness cases, followed by Black or African American individuals at 29%, and White residents at 26%.

Key Findings from the Report
Several key findings from the HCPH report highlight the severity of the heat-related risks in Harris County:
- Heat-Related Illnesses: From 2019 to 2023, Harris County recorded 7,627 heat-related illnesses, with 61% of these occurring during days when the heat index exceeded 103°F.
- Rising Temperatures: The report also noted a consistent upward trend in average temperatures, with more days exceeding 100°F and nights remaining above 80°F expected in future years.
- Vulnerable Populations: The findings pointed to the heightened risk among outdoor workers and specific demographic groups, especially Hispanic or Latino residents.
Public Health Measures and Protection Tips
In response to these alarming findings, HCPH is urging residents to take proactive steps to minimize the risk of heat-related illnesses, particularly during extreme heat events. The public health department recommends several simple yet effective measures, including:
- Staying hydrated by drinking plenty of water.
- Wearing lightweight, loose-fitting clothing to stay cool.
- Limiting outdoor activities, particularly during the peak heat hours of midday.
- Utilizing air conditioning and energy-efficient cooling solutions indoors.
- Visiting cooling centers during extreme heat events to find relief from the high temperatures.
Looking Ahead: Year-Round Concern
While this report was released as the weather begins to cool down in the county, the issue of excessive heat remains a year-round concern. Jennifer Kiger, Director of the Office of Epidemiology, Surveillance, and Emerging Diseases at HCPH, highlighted the importance of ongoing public health awareness and action. “Excessive heat is a serious and growing public health concern,” said Kiger. “This report provides critical data to help policymakers, healthcare professionals, employers, and community leaders make informed decisions to mitigate the dangers of heat-related illnesses and improve health outcomes for all community members.”
HCPH remains committed to expanding partnerships and implementing long-term strategies to combat the risks associated with excessive heat. Dr. Brown emphasized the urgency of proactive measures: “We cannot wait for another heatwave to act. We must work together as a community to prepare for and respond to extreme heat, ensuring that everyone in Harris County can be safe.”
