Itís hard to define sunstroke. For this discussion, letís think of it as we would heatstroke. Heatstroke happens when the body can no longer maintain a temperature of under 105 degrees when exposed to or exercising in hot weather. It is a life-threatening condition.
People almost always have warning symptoms before heat stroke. Sometimes they do not pay attention. Or they may be very old or disabled, and not able to take action.
The first symptoms of overheating are:
Once heatstroke sets in, youíd stop sweating, but not be thirsty. This is a very dangerous combination. Next, youíd start to be confused. A headache may come on at any time. But it is not always present in heatstroke.
Once someone shows any behavior changes related to dehydration or overexposure to heat, then the situation becomes an emergency.
Preventing heatstroke comes down to common sense. If you need to compete in warm temperatures, then you must drink plenty of fluids regularly. You should replenish fluids with a combination of sports drinks and water. Avoiding too much exposure to the sun and heat is the best prevention.
