Texas heat safety: New guidelines and health risks for vulnerable groups

As North Texas experiences prolonged periods of triple-digit temperatures, health experts and educators are emphasizing heat safety protocols. The National Weather Service has indicated that high temperatures and rising heat indices are expected to persist through the fall.

To mitigate risks during outdoor activities, the University Interscholastic League (UIL) has implemented new guidelines requiring the use of wet-bulb globe temperature meters. Students at Texas State Technical College are receiving training on these devices to ensure accurate readings for athletic personnel. Instructors recommend performing outdoor work in the early morning to avoid the hottest afternoon hours.

Medical professionals at UT Southwestern Medical Center warn that older adults are at a significantly higher risk for heat-related illnesses, such as heat exhaustion and heat stroke. Due to physiological changes associated with aging, such as reduced sweating capacity and decreased thirst sensation, individuals over 60 may struggle to regulate core body temperatures. Symptoms of heat exhaustion include dizziness, fatigue, nausea, and weakness, which require immediate cooling and hydration.
