Summer is here, bringing lush nature, beautiful colors, and a wide array of outdoor activities. However, this time of year also means heatwaves and a need for caution. Because seniors' health is particularly at risk during extreme heat, Bonjour Résidences outlines key preventive steps, symptoms to watch out for, and what to do in case of heatstroke.
1. Monitor the Weather Forecast
Anticipating upcoming heatwaves allows you to better prepare and prevent the adverse effects of extreme heat. Make sure to regularly check the following indicators:
Environment Canada Heat Warnings: Weather alerts are issued by Environment Canada when the forecast temperature is expected to exceed 30°C with a humidex value of 40, or reach 40°C or higher for at least one hour. This is referred to as extreme heat. If these temperatures persist for more than 3 consecutive days, it is officially classified as a heatwave, which is a situation that requires close monitoring for seniors.
Humidex Index: Extreme heat is often accompanied by high humidity. Moisture in the air prevents the body from cooling down effectively through sweat, increasing the risk of heatstroke or health complications for older adults. To better assess this, the humidex indicates what the temperature actually feels like. When it exceeds 30, humidity can cause discomfort. The humidex value becomes particularly critical for seniors when it rises above 40.
2. Keep Your Living Space Cool
To protect your health during a heatwave, maintaining a cool indoor temperature is essential. Be sure to:
Turn on the air conditioning to a comfortable ambient temperature if you have it (ensure it is fully functional before the heatwave hits);
Use fans to keep the air circulating;
Close blinds, shades, or curtains during the day to keep the heat out;
Open curtains and windows in the evening to let the cool night air in;
Avoid cooking hot meals and using the stove or oven on high-heat days.
If your home gets too hot, consider spending at least two to three hours a day in a cooler environment. Local public libraries and shopping malls are great air-conditioned options. If possible, consider getting out of urban areas, where temperatures are generally much higher.
3. Stay Hydrated and Eat Fresh Foods

During periods of high heat, hydration is your best line of defense. Older adults must pay special attention to this, as they naturally experience a decreased sense of thirst and are therefore at a higher risk of dehydration. The most crucial step is to drink fluids regularly and in sufficient quantities. Above all, do not wait until you feel thirsty!
To prevent dehydration in seniors, remember to:
Drink 6 to 8 glasses of water per day;
Keep glasses of fresh water close at hand as a visual reminder to drink;
Avoid alcoholic beverages, tea, or coffee, as these tend to dehydrate the body;
Eat fresh fruits and vegetables with high water content;
Eat enough food, even if you do not feel hungry. Feel free to consult our Guide to Essential Vitamins and Minerals for Seniors to ensure proper nutritional intake despite the heat.
4. Cool Down Regularly and Avoid Unnecessary Exposure
To maintain a safe body temperature, it is recommended to take cool baths or showers during a heatwave. You can also apply damp, cool towels to the face and other parts of the body to cool down.
Avoid all unnecessary physical exertion and rest as much as possible. This preserves your energy and prevents your core body temperature from rising. If you still want to stay gently active during the cooler hours of the day, discover The Benefits of Yoga for Seniors’ Health.
Whenever possible, it is best to stay indoors or in a cool place rather than going out. To keep yourself entertained indoors without overexerting yourself, it is the perfect time to focus on calm, low-energy activities; for instance, explore The Benefits of Bingo for Seniors in Retirement Residences. If you must go outside, remember to:
Wear loose, lightweight, light-colored clothing;
Equip yourself with a hat, sunglasses, and sunscreen;
Stay in the shade as much as possible;
Hydrate regularly.
5. Check In With Loved Ones
Isolation is one of the leading risk factors for seniors during a heatwave.
In preparation for extreme heat, ask your loved ones to check in on you regularly to monitor how you are feeling. In the event of an issue or concern, they can directly contact emergency services. If you are a caregiver or family member, make it a point to call or visit your elderly relative more frequently during periods of extreme heat and high humidity. Also, keep emergency phone numbers clearly visible and close at hand.
What Symptoms Should You Watch For?
To monitor health status during a heatwave, look out for early signs of dehydration or heat-related illness, such as:
Muscle cramps and headaches;
Severe fatigue, dizziness, or fainting;
Swelling of the hands, feet, and ankles;
Nausea;
Rapid heart rate or accelerated breathing;
Extreme thirst and dark urine.
Beware of Heatstroke
It is crucial to recognize the definitive signs of heatstroke, which include:
Dizziness and a dangerously high body temperature;
Red, hot skin and confusion;
A complete lack of sweating.
Heatstroke or sunstroke is a severe medical emergency. Prompt action is vital if you or someone near you experiences these symptoms. In case of heatstroke, contact a medical professional immediately or call 911. While waiting for emergency services to arrive, move the person to a cool area, apply cool water to the warmest parts of their body, and fan them as much as possible.

Frequently Asked Questions
Q: Why are seniors more vulnerable during a heatwave?
A: As the body ages, it becomes less efficient at regulating temperature. Additionally, older adults experience a decreased sense of thirst, which increases the risk of dehydration. Certain chronic health conditions can also impair the body's ability to adapt to high heat.
Q: How long can a heatwave last in Quebec?
A: In Quebec, a heatwave is generally defined as three consecutive days where temperatures reach or exceed 30°C with high humidity levels. While its duration can vary, it typically lasts from a few days to a week.
Q: Can medications increase heat-related risks?
A: Yes, certain medications, such as diuretics, antihypertensives, or antidepressants, can affect fluid balance or body temperature regulation. It is important to consult a healthcare professional regarding this matter.
Q: Which foods should be avoided during a heatwave?
A: It is best to avoid heavy, fatty, or very salty meals, as they can worsen dehydration. Instead, opt for light, water-rich options like salads, fresh fruits, and raw vegetables.
Q: How should seniors' daily activities be adapted during a heatwave?
A: During a heatwave, physical activities are best done early in the morning or in the evening. It is recommended to limit outdoor chores and choose calm indoor hobbies instead. Rest is also crucial to prevent physical exhaustion.
