Heat can be hazardous to your health. Here’s what you need to know.

As summer heat tightens its grip on North Texas, mobile health care provider and ambulance service MedStar is reminding us that prolonged or intense exposure to hot temperatures can cause heat-related illnesses such as heat exhaustion and heatstroke. MedStar explains:

Heat exhaustion occurs when the body loses large amounts of water and salt through excessive sweating, particularly through hard physical labor or exercise. This loss of essential fluids can disturb circulation and interfere with brain function. Symptoms may include muscle cramps, paleness, sweating, nausea and vomiting. Children and the elderly are especially susceptible.

Heatstroke is a life-threatening problem that occurs when the body suffers from long, intense exposure to heat and loses its ability to cool itself. Some of the most common signs of heatstroke include confusion, vomiting, hot and flushed skin, rapid heart rate, decreased sweating, shortness of breath, decreased urination, increased body temperature (104-106). Symptoms can also include convulsions. Heatstroke is a medical emergency, MedStar says. If you or someone you know experiences any of these symptoms, call 911 immediately.

While heatstroke and heat exhaustion are common this time of year, MedStar says they can be easily prevented:

  • Hydrate: Drink plenty of water during the day, especially if engaged in strenuous activity. Sports drinks are a good choice if you’re exercising or working in hot conditions, but water is a good way to hydrate as well.
  • Ventilate: Stay in a place where there is plenty of air circulating to keep your body cool. If you are indoors and don’t have access to air conditioning, open windows and use a fan.
  • Cover up: Wear light-colored and loose-fitting clothing to avoid absorbing the sun’s light and trapping heat. Wear a hat to shield yourself from the sun, but once you feel yourself getting warm, remove any items covering your head which can trap heat close to your body.
  • Limit activity: Heatstroke can occur in less than an hour when participating in strenuous activity on a hot day. If you feel yourself getting hot or lightheaded, stop your activity and rest in a cool place out of the sun. Be sure to drink water or a sports drink before, during and after any strenuous activity.
  • Check on loved ones: The elderly are especially vulnerable to heat related emergencies. Many elderly residents are not aware of how hot it may get in their residence. Call on older friends and family members regularly to assure they are OK.
