Take effects of heat illness seriously

For those of us who live in fabulous Las Vegas, the summer months produce ongoing, triple-digit temperatures. We all know it is uncomfortable, but did you know it could be life-threatening? Heat exhaustion and heat stroke are serious conditions, which should never be ignored. Profuse sweating is usually the first sign of a heat-related illness. When one develops pale, moist skin, muscle cramps and nausea, it can quickly progress to dizziness, weakness and headache. If this happens, act quickly by getting into a cool place, loosening clothing and applying cool water to the skin. Drink plenty of water. Avoid drinks containing alcohol, caffeine and sugar, which will increase loss of fluid.

Heat stroke is an emergency situation. Usually the person stops sweating. He/she may become disoriented, develop chest and/or abdominal pain and lose consciousness. The body temperature can rise to 104 degrees. If this happens, call 911.

When I moved to Las Vegas from New Jersey in July 2003, I met my moving van at a storage facility, where my possessions were to be delivered. I had cataloged each carton. As the items were removed from the van, I checked off each one. I was standing in the sun and began to sweat profusely. It never occurred to me to stop until I became dizzy and weak. I was well acquainted with symptoms of heat exhaustion and heat stroke, through my lifeguard training and first aid. Fortunately, my daughter was with me and she took over while I took refuge in the air-conditioned office. I continued to sweat for the next 20 minutes, while the office manager supplied me with water to drink and a wet cloth for my face and neck. I truly believe that quick action averted a possible disaster.

Everyone is susceptible to the effects of excessive heat. Seniors are more vulnerable than their younger counterparts. No matter how well you have taken care of your health, deterioration is happening. We can slow it down, but we cannot stop it. It is a fact of life.

Perspiration is the body's way of keeping us cool. As we age, the number of sweat glands diminish and don't work as efficiently as they once did. Aging skin does not readily adjust to extreme temperatures. Some medical conditions, such as heart, kidney, central nervous system diseases, dehydration, diabetes and certain medications, can decrease the body's ability to perspire.

To me, air conditioning is a major miracle. Without it, there would be no fabulous Las Vegas. Make sure that both your home and auto air conditioners are in good working order. It is wise to have both serviced before the extreme heat sets in. Change the filter at least once a month.

Plan to run errands the first thing in the morning. If your exercise includes walking, begin before 9 a.m. That goes for any outdoor activity, such as gardening.

I love to swim and exercise in an outdoor pool. I know my body temperature will stay cool, but the water does not protect my skin from the sun. Sunscreens, sun blocks and sunglasses are a must. While exercising, I wear a cotton hat to protect my scalp. I never thought I'd see the day!

When temperatures soar to 110 or more, I use the pool before 10 a.m. or after the sun goes down.

Many seniors in Las Vegas are retired transplants from other states. The summer may be a good time to visit friends and family, where the summers are less severe. I would not recommend a motor trip through a long stretch of desert.

And, don't forget about your pets. They are affected by the heat just as much as you are, especially if he/she is older. Never leave them in a parked car; not even for a few minutes. The temperature can rise quickly to 135 to 145 degrees, which can be fatal. Black surfaces, such as roads, parking lots and driveways, retain the heat, which emanates upward.

Remember, pets are closer to the ground than we are. If you suspect your pet is reacting to the extreme heat, bring him/her into the house and sponge him down with tepid water. Its best to walk your pet before 9 a.m. or after the sun goes down.

There are lots of fun, outdoor activities to enjoy here in Las Vegas. Have a good time with them, but be sure to be take immediate action if you experience any heat-related symptoms.
