As we mature, decreased blood circulation and a less efficient perspiration mechanism make it harder for our bodies to regulate temperature. Common health conditions such as cardiovascular disease, kidney or lung problems or obesity are also a factor. Even the medications we take can interrupt the body’s ability to protect itself.

During warm weather, be sure to check on older friends and loved ones. Here are some suggestions to help them stay safe and cool during periods of higher heat:

Encourage them to drink plenty of fluids, even if they don’t feel thirsty. On hot days, the body loses moisture more rapidly, so it’s important to stay hydrated with water or fruit juice. Avoid caffeine and alcohol, which cause the body to dehydrate. (Seniors who are on a fluid-restricted diet should follow their healthcare provider’s instructions during periods of heat.)

In instances where your loved one’s home does not have air conditioning, keep the temperature comfortable by letting in cool air during the early morning and evening hours. Create cross-ventilation by opening windows on two sides of the building. Use fans to circulate cooler air. Close curtains and blinds during the warmest hours.

If the home is still uncomfortably warm, arrange for your loved one to take a break at an air conditioned environment during the more blistering points of the day. Shopping malls, movie theaters and libraries are usually air conditioned. And many communities provide emergency cooling shelters, located in schools, community centres, auditoriums and other public places.

Insist on weather appropriate clothing such as; short-sleeve, loose-fitting garments. Natural fibers and light colors are cooler than synthetic materials and dark colors. And don’t forget a sun hat!

Have them use sunblock when outdoors. Sunburn is a major contributor in reducing our body’s ability to regulate heat.

Be Alert for Heat-Related Illness! Dizziness, weakness, nausea, and excess perspiration are all tell-tale signs that you loved one my be experiencing heat exhaustion, and should quickly move to an air-conditioned or other cooler.
