Protecting yourself from heat stroke

Q. I've heard summer heat is especially dangerous for seniors. Why, and how can I protect myself?

A. After age 50, one starts to become more susceptible to the effects of heat stroke. According to the Centers for Disease Control and Prevention, heat stroke occurs when the body's temperature rises so rapidly that it loses the ability to sweat adequately to cool down.

Common symptoms of heat stroke include dehydration, nausea, seizures, confusion, disorientation, and, sometimes, loss of consciousness or coma.

At this point in the summer, it may be too late to acclimate gradually, but it's generally wise to get used to heat slowly by, for instance, taking brief walks.

If you are taking prescriptions, its important to talk with your doctor about side effects, as some medications affect the ability to sweat.

Remember to stay hydrated. Drinking plenty of water is crucial in avoiding heat stroke. Also, keep an eye on the forecast. If the temperature is above 90 and the humidity is more than 95 percent, it is best to stay indoors in air-conditioning.

Make sure the air conditioner is set no higher than 76 degrees, even if you leave the house for a couple of hours. Most air conditioners cannot cool down a residence after being turned up or off throughout a long, hot day.

If you suspect that you are experiencing heat stroke, place ice cubes on your head or immerse your head in cold water. This works faster to cool you down than drinking a glass of water. If symptoms worsen, seek immediate medical attention.

Help ensure that your older friends, family members, and neighbors are following these tips, too, in order to ensure a safe and healthy summer for all.
