Beat the Texas Heat: Know the Difference Between Heat Injury and Heat Stroke

Written By paige wolk

Texas summers can be dangerous, especially for older adults. As we age, our bodies become less efficient at regulating temperature, and some medications can increase the risk of heat-related illness.

Heat injury (heat exhaustion) occurs when the body becomes overheated and loses too much fluid and salt through sweating. Warning signs may include:

  • Excessive sweating

  • Dizziness or lightheadedness

  • Headache

  • Muscle cramps

  • Nausea

  • Weakness or fatigue

If you notice these symptoms, move to a cool place, drink water, and rest.

Heat stroke is much more serious and is a medical emergency. It occurs when the body can no longer control its temperature. Signs may include:

  • Confusion or unusual behavior

  • Fainting

  • Hot skin

  • A body temperature of 103°F or higher

If heat stroke is suspected, call 911 immediately.

Simple Ways to Stay Safe

  • Drink water regularly, even if you do not feel thirsty.

  • Limit outdoor activities during the hottest part of the day (10 a.m. to 4 p.m.).

  • Wear lightweight, light-colored clothing.

  • Use air conditioning or spend time in a cool public place if your home is too warm.

  • Check on friends, neighbors, and family members during heat waves.

A few simple precautions can help you enjoy summer safely. Remember: heat injury can often be treated early, but heat stroke is a medical emergency. Stay cool, stay hydrated, and don't underestimate the Texas heat.
