Report links climate events to rising health impacts

Chronic illnesses and mental health challenges are becoming harder to manage as extreme weather events intensify, according to a new report from Sun Life.

The findings show that existing health conditions, such as migraines, cardiovascular disease, allergies, and anxiety, are being aggravated by climate-related impacts, with consequences for Canadian employees and workplaces.

The survey of more than 2,000 employees found that 77% had experienced an extreme weather event in the past three years. Nearly two-thirds (59%) said the experience affected their physical health, while over half (54%) reported an impact on their mental health. Common effects included anxiety, stress, and disrupted sleep.

Employees living with one or more chronic conditions were particularly vulnerable. They were twice as likely as others to report both physical and mental health impacts from climate events. Many also indicated that managing their illness had become more difficult. Almost half (45%) of women reported worsening conditions, compared with 30% of men.

Workplaces are also feeling the strain. Among employees who reported health effects, more than half (54%) said they experienced reduced productivity, higher absenteeism, and lower engagement.

“Impacts on employee well-being can have major consequences for workplaces,” said Marie-Chantal Côté, senior vice-president of Sun Life Health. “Employers play a crucial role in supporting their workforce by leveraging and bringing awareness to the resources in their group benefits plans. Empowering employees to proactively manage their health and use available supports is more important than ever in today’s changing environment.”

The report also highlights generational differences in how employees experience climate anxiety. Almost half (47%) of Gen Z employees reported climate-related anxiety, compared with 27% of the broader workforce. One in five workers also said they experienced fatigue or burnout linked to weather events.

With chronic disease and mental health issues already contributing significantly to long-term disability claims, Sun Life says building resilience is key. The insurer noted that three-quarters of employers believe group benefits can help employees manage climate-related health challenges.

Sun Life noted that resources such as specialty care programs for chronic illnesses, virtual care services and employee assistance programs can support employees in maintaining well-being as climate change continues to shape daily life.
