The punishing summer heat in North Texas is having a deleterious impact on folks hanging around outside, with first responders noting that they have seen an increase in heat-related calls.

As previously reported by The Dallas Express, Dallas County logged its first heat-related death last week after a 79-year-old Dallas resident died of heat-related illness.

The metroplex experienced a historically hot summer last year, with triple-digit highs leading to the deaths of more than 20 people, as DX reported. While things have not gotten that bad yet this year, August has had its fair share of 100-plus-degree days, with the high on August 6 coming in at 106 degrees.

To avoid heat-related illness, stay hydrated by drinking plenty of water, wear lightweight, breathable clothing, and avoid strenuous activities during peak heat hours. Take breaks in shaded or air-conditioned areas, and listen to your body — if you feel dizzy or nauseous, cool down immediately and seek medical attention if needed.

Here’s some of what NBC 5 DFW reported on the increase in heat-related calls:

First responders have been busy this summer with heat-related calls, which have ramped up significantly over the past several days.

Slightly cooler temperatures are coming, but emergency crews still caution the public to remain vigilant.

Oak Cliff resident Stephanie Murray said outdoor activity is central to her wellness routine. Over the past week, though, her plans have been sidetracked.

“There have been days where it was just way too hot to get outside and walk — 106, 105, and it’s sweltering,” said Murray.

When she gets to Lake Cliff Park, the goal is a three-mile walk, with safety at the forefront.

Dallas paramedic Andres Esquivel told NBC 5 that heat-related calls come in as environmental emergencies and specific locations make people more susceptible.
