Public health authorities in North Texas are warning residents to take precautions as rising temperatures drive an increase in heat-related illnesses across the region. Dallas and Tarrant counties have both recorded a higher proportion of emergency room visits attributed to heat issues this summer compared to the same period in 2025.
Data from Dallas County shows 283 cases of heat-related illness in June 2026, an increase from the 238 cases recorded in June 2025. However, these figures remain significantly lower than the 481 cases reported in June 2023, a month that included 55 days with temperatures reaching triple digits.
Dr. Philip Huang, director of Dallas County Health and Human Services, noted that current rates are comparable to previous years. Historical data indicates that the majority of heat-related illnesses occur between July and September. During those months in 2025, the county recorded over 700 cases, while 2023 saw more than 1,700 cases.
In Tarrant County, officials are monitoring the trend closely. Dr. Brian Byrd, the county’s public health director, explained that tracking the share of emergency room visits helps determine the impact of extreme heat on the broader emergency care system. This metric is particularly useful during large events that draw crowds, such as the upcoming World Cup matches.
Despite a recent increase in emergency room visits coinciding with World Cup games, Dr. Byrd stated there is no strong correlation between the event attendance and heat-related illness. He observed that residents have generally managed the heat well so far.
With hot weather expected to continue, health officials are advising the public to remain vigilant. Recommendations include drinking plenty of fluids, taking frequent breaks for those working outdoors, and watching for symptoms such as dizziness, muscle cramps, or excessive sweating. Staying in air-conditioned environments is also strongly encouraged.
