How to Stay Cool in Your Home This Summer
This week, undergraduate student Samah Saci shares her top tips for staying cool indoors during the warmer months.
Summer is right around the corner and for many of us, this means glowing suntans, family picnics, and an endless supply of chocolate ice cream. Unfortunately, it also means the potential for dehydration, heat exhaustion, and other heat-related issues. With the predicted rise in heat waves, it is important to initiate behaviours that minimize heat-related illness and mortality.
It may come as a surprise that heat-related illness can often occur indoors. During a heat wave, in the absence of adequate protective measures (e.g. air conditioning, window coverings such as blinds, etc.), buildings and homes are unable to effectively cool down, causing heat to accumulate for several days. The resulting effects can pose a great risk to vulnerable populations such as seniors and those with chronic health conditions, who possess compromised thermoregulatory function and are less likely to use a home air conditioner.
Here are some ways to keep cool this summer season. The following tips should offer a good start to a healthy and productive summer.
Stay hydrated
Dehydration can exacerbate the effects of high indoor temperatures. Rather than reaching for your favorite cola, take advantage of nature’s bounty. Toss your favourite fruits into a blender or make a refreshing pink lemonade. Keep a jug cooled in the refrigerator and treat yourself to unlimited refills throughout the day.
Conserve your energy
During a heat wave, lower the amount of heat your body is producing by engaging in more passive activities. Perhaps watch an episode (or two) of your favourite television series or pick up a good novel and let your mind do the wandering.
Less is more
The use of household appliances, like those used during cooking, tends to increase indoor temperatures. Try to prevent this by cooking less frequently or plan your meals around the outdoor barbecue. This will help keep the heat outdoors while keeping things cool inside. On cooler days, or at night when rooms are cooler, it may help to make a batch big enough to last a couple of days or to increase the amount of raw vegetables in your meals.
Move to a cooler space
Homes without air conditioning tend to be hottest in the upper floors. Try to spend most of the day in cooler parts of your home, such as the basement.
Take a cool bath or use cold towels
Taking a cool bath or shower will rapidly reduce body temperature and provide some respite from hot indoor temperatures. Placing cold, wet towels on your body will have a similar effect.
Since vulnerable individuals spend the majority of their time indoors, it is especially important to remain aware of the risks associated with overheated buildings. To help minimize the risk of heat-related illness this season, let’s unleash our minds’ creativity and discover enjoyable ways to keep cool.

Exercising in the heat with Type 2 Diabetes
This week, Dr. Kenny shares his insights on how to safely manage type 2 diabetes while exercising or performing physical activity in hot environments.
When you have type 2 diabetes, physical activity is an important component of your treatment plan. However, performing physical activity, especially in the heat, can place you at an increased risk for heat-related injuries. In fact, performing any form of physical activity in warm conditions, no matter how light the intensity, dramatically increases an individual’s risk of heat-related injury or death, regardless of age or health. This is because physical activity augments metabolic heat production and therefore the rate at which heat must be dissipated to the environment to prevent dangerous increases in core temperature.
Normal aging causes marked reductions in the body’s capacity to dissipate heat resulting in a greater increase in core temperature during heat exposure at rest and during exercise. This maladaptive response occurs in adults as young as 40 years of age and is worse in individuals with type 2 diabetes. This means that older adults and individuals with type 2 diabetes are at an augmented risk of heat-related morbidity. Reduced physical fitness and the presence of metabolic, cardiovascular, and neurologic dysfunctions, which are often associated with diabetes, further exacerbate an already compromised ability to dissipate heat. Additionally, hyperglycemia and/or medication use can lead to greater levels of dehydration especially during exposure to heat at rest or during physical activity, which can reduce heat tolerance.
People with type 2 diabetes should take steps to stay cool while performing physical activity in warm weather. If physically activity is performed, it should be conducted in the early or later hours of the day when the temperatures are cooler and the sun is not at its peak. Limit the duration of physical activity to brief (<15 min) successive bouts interspersed with an adequate rest period in a shaded, well-ventilated area while rehydrating.
