Hello everyone, I hope you’re doing well and enjoying the return of warmer days. After the long winter we’ve had, I’ve found myself reflecting quite a bit on climate change and how it affects our daily lives—especially as we get older.
I recently had the chance to attend a conference by the Centre d’excellence en vieillissement de Québec (CEVQ) on aging in the context of environmental changes. It really got me thinking, and I came away with a few insights that stayed with me. I thought I would share some of those reflections with you.
Older adults are more vulnerable to climate changes
Climate change is affecting our daily lives—and older adults are often more at risk. As we age, our bodies don’t adjust to temperature changes as easily. For example, we may not sweat or shiver as effectively, which makes it harder to cool down or warm up. We may also feel less thirsty, even when our body needs water, increasing the risk of dehydration.
The heart and lungs also become less efficient over time. This can make it harder for the body to circulate oxygen and cope with extreme temperatures, sometimes leading to fatigue, dizziness or weakness. Because of these natural changes, heat waves and cold spells can have a stronger impact on older adults.
Some situations can increase these risks even more. Living with a chronic health condition, taking certain medications, or feeling socially isolated can all make it harder to stay safe during extreme weather. Financial challenges may limit access to air conditioning or heating. Access to clear, easy-to-understand information also plays an important role in staying safe and prepared.
What you can do
At the individual level: Small actions can make a big difference. Try to keep your home cool or warm depending on the season, and create a shaded or comfortable space. It can also help to gradually adapt to temperature changes rather than facing them all at once.
- If you are over 65, drink water regularly—even before you feel thirsty.
- Choose light meals to help regulate body temperature, like salads and sandwiches.
- Plan ahead by identifying an emergency contact and preparing a small emergency bag.
- Staying informed is also key. Sign up for Conseil climat, a free phone call service to alert you about heatwaves.
You may also be supporting someone aged 65 or over who has additional risk factors, such as health conditions or reduced mobility. In that case, a few extra precautions can help. Check in regularly, especially during very hot or cold days, and watch for signs of discomfort, confusion or unusual fatigue. Encourage them to drink fluids and to stay in a comfortable environment. You can also help by keeping their space cool or warm, making sure important phone numbers are easy to reach, and staying informed about weather alerts (rainstorms, heatwaves, etc.) so you can act early if needed.
At the community level: Looking out for one another matters and can make a real difference. Check in on neighbours, identify people who may be more vulnerable, and share reliable information with each other. Community support helps ensure that everyone has access to safe, comfortable spaces during extreme weather.

Finding balance between concern and action
It’s understandable that conversations about climate change can bring up anxiety, stress and even fear. I find it helpful to focus on what is within our control—clarifying our zones of influence and channeling these emotions into meaningful and constructive action. I invite you to reflect on what you can realistically do in response to the risks mentioned above, and to gently let go of what lies beyond your reach.
Amid these challenges, it’s also important to stay connected to what remains steady and life-giving: The simple privilege of fresh air in our lungs, the beauty of the St. Lawrence River, and the presence of our loved ones around us.
Wishing you a lovely month of May!
