During a heatstroke, your body's ability to regulate your temperature becomes overwhelmed and can't keep up enough through sweating to cool you off. The occurrence of a heatstroke while walking can be very dangerous, so it's important to know how to prevent it from happening and to recognize the signs if it does take place.
Risk Factors
Young children and the elderly are especially susceptible to heatstroke, as are those who are obese. Being or becoming dehydrated while walking also puts you at risk of a heatstroke, as can cardiovascular disease and certain medications. A variety of medications can increase the likelihood of a heatstroke, so ask your doctor if any of your medications can put you at risk. Diuretics, neuroleptics and anticholinergics are some of the medications that can increase your chances of heatstroke during hot weather.
Avoiding a Heatstroke While Walking
Avoid going for long walks when the weather is very hot. Drink plenty of fluids both before and during walks. Wear light colored, lightweight clothing for walking, advises the University of Maryland Medical Center. Never drink alcohol before or during exercise.
Signs of a Heatstroke
Some symptoms of heatstroke are a fast heartbeat, rapid breathing and changes in blood pressure. Other signs include fainting, nausea, a headache, dizziness and confusion. If you stop sweating when walking on a hot day, this is a sign of heatstroke, warns the Mayo Clinic website.
What to Do
If you suspect that you or a walking companion is suffering from heatstroke, stop walking immediately. Call 911 as soon as possible. In the meantime, get out of the sun, drink some cool water, and keep cool by directing a fan at yourself or the other person, or spray cool water on the person, if possible.
Things to Avoid
If you suspect that someone with you is having a heatstroke, knowing what not to do can be as important as knowing what you should do. For example, never give someone who may be having a heatstroke drinks containing either alcohol or caffeine. Don't give the person any medications, even acetaminophen or aspirin. Although salt tabs may seem like a good idea for someone who has lost a good deal of salt in the heat, don't give them to someone with a suspected heatstroke. Also avoid giving an alcohol rub to a person who may have had a heatstroke, advises Medline Plus.
Possible Complications of Heatstroke
Suspected heatstroke should be taken very seriously. Someone who has had a heatstroke may go into shock. Heatstroke can also cause organ failure and brain damage. In severe cases, heatstroke can even cause death.
