Heat Related Illnesses and Heat Safety

Medical City Las Colinas July 14, 2015

Heat related illness, such as heat exhaustion and heat stroke, are a very real threat in the Texas sun. Heat exhaustion is when the body overheats when you are too active in hot temperatures. Heat stroke is a more severe illness that can be life threatening.

Symptoms of heat exhaustion may include:

  • Temperature over 37.8°C (about 100°F)
  • Fast pulse
  • Moist skin, sweating
  • Muscle cramps and tenderness
  • Nausea, vomiting
  • Lightheadedness
  • Confusion
  • Headaches

Symptoms of heat stroke may include:

  • Temperature over 40.5° C (about 105° F)
  • Weakness, lightheadedness
  • Blurred vision
  • Confusion, delirium, unconsciousness (can progress to coma)
  • Seizures
  • No sweating
  • Pale, dry skin
  • Fast breathing, fast heartbeat

There are steps you can take to avoid putting yourself or your loved ones in danger this summer:

  • Avoid prolonged exposure to high temperatures.
  • If you have to work or exercise under hot conditions, drink lots of fluids (preferably sports drinks, which contain both salt and sugar), and take frequent breaks in the shade.
  • If you have a risk factor for heat exhaustion or heat stroke, be careful participating in activities in hot weather. Take regular rests and drink lots of fluids.
  • During heat waves, try to spend time indoors with air conditioning or go to an air-conditioned shelter. This is especially important for older adults.

Thomas Lee Jr. experienced the dangers first hand after a heat stroke led him to a 9-day stay at our facility last summer. Lee was able to make a tremendous recovery while working with the staff of Medical City Las Colinas.
