(Special)-When temperatures climb, older adults are at higher risk of health problems if they don't take the proper precautions to protect themselves from the sweltering heat.  

According to the American Geriatrics Society's Foundation for Health in Aging, older people can't cool down as well as those younger ones because of some of the physical changes that happen as we age.

Just as important, older people may not feel hot when the temperature is dangerously high.  They are also less likely to feel thirsty, even when they are almost dehydrated, which means that their bodies have lost dangerous amounts of water.

Heart disease, diabetes and some other diseases that are common among older adults can make it even more likely that they'll have problems when it's hot. So can certain drugs, including water pills, allergy and sinus medications, and drugs for depression and nerve problems.

Staying safe when it’s hot

Temperatures don't have to be tremendously high to cause health problems in older adults - temperatures in the lower 30s can be very dangerous for older people.

Because older adults may not feel hot, even when it's dangerously warm, they and the people who care for them should check the temperature often during the summer.

Here are some tips for staying safe when it’s hot:

·    Turn on the air conditioner or go where it's air-conditioned - a shopping mall, grocery store, senior centre, movie theatre, museum, or library, for example. Fans aren't enough.

·    Don’t walk long distances, lift heavy objects, or do other strenuous things.

·    Drink lots of water and other clear drinks that don't contain alcohol or caffeine, which can "dry you out"). Remember: If your urine is a light yellow colour, you're drinking enough water. If it's darker yellow, you need to drink more.

·    Take cool showers, baths, or sponge baths.

·    Wear lightweight, light-coloured, loose-fitting clothing. Clothes made of lightweight cotton are a good choice.

·    Wear a hat.

·    Stay out of the sun.

Dizziness, weakness, nausea, a high body temperature and passing out are among the symptoms of health problems caused by heat.  If you are affected by them, get to a cool place, drink plenty of water or sports beverages, and call 911 if they seem severe.
