Deadlines, demands, disease — How your stressful job is crushing your cardiovascular health

BALTIMORE — Is your job stressing you out? Those workplace pressures might be doing more than just ruining your mood – they could be harming your heart health too. That’s according to an important new study which found that people experiencing work-related stress were significantly more likely to have poor cardiovascular health compared to their less-stressed colleagues.

The research, published in the Journal of the American Heart Association, comes at a critical time when workplace wellness is increasingly under the microscope. With about 60% of the U.S. population in the workforce and many employees reporting feeling overwhelmed by job demands, understanding how occupational stress affects our health has never been more crucial.

The study, led by researchers at Emory University and other major institutions, examined data from over 3,500 adults between ages 45 and 84 who participated in the Multi-Ethnic Study of Atherosclerosis (MESA). This diverse group included White, Black, Hispanic, and Chinese American participants from six different regions across the United States, making it one of the most comprehensive looks at work-related stress and heart health in different populations.

But what exactly do we mean by “cardiovascular health”? The American Heart Association measures it using what they call “Life’s Simple 7” – seven key factors that indicate how healthy your heart is: smoking status, physical activity, body mass index, diet, total cholesterol, blood pressure, and blood glucose levels. Think of it as a report card for your heart, where each factor gets scored as poor, intermediate, or ideal. The better you score across all seven categories, the better your overall cardiovascular health.

Overall, about 20% of participants reported experiencing work-related stress, and these individuals were significantly less likely to have favorable cardiovascular health scores compared to their less-stressed counterparts. In particular, stressed workers were markedly less likely to get enough physical activity – perhaps not surprising when you consider how a demanding job can leave you feeling too drained to hit the gym after work.

The science behind this connection is fascinating. When you’re stressed, your body releases hormones like cortisol and epinephrine – the same chemicals involved in our ancient “fight or flight” response. While this response was great for our ancestors running from predators, having these stress hormones consistently elevated due to work pressure isn’t so helpful. Over time, excessive cortisol can actually make your body resistant to its own anti-inflammatory properties, potentially leading to increased inflammation and atherosclerosis (the buildup of plaque in your arteries). Meanwhile, elevated epinephrine levels can activate platelets and macrophages in your blood, potentially contributing to cardiovascular problems.

With an increasing proportion of employees now age 55 and older, and healthcare costs rising, workplace wellness has never been more critical. Consider this: 25-30% of employers’ annual healthcare spending goes toward employees with major cardiovascular risk factors like smoking, physical inactivity, obesity, high blood pressure, poor cholesterol levels, and diabetes.

The news isn’t all doom and gloom, though. The researchers suggest that workplace wellness programs could be key to addressing this issue. Since we spend so much of our waking hours at work, the workplace provides an ideal setting for implementing health initiatives that could help reduce stress and improve cardiovascular health.

The stakes are high – cardiovascular disease affects one in three U.S. adults and costs the healthcare system over $407 billion between 2018 and 2019. But by understanding the connection between workplace stress and heart health, we can better target interventions to help protect workers’ cardiovascular well-being.

“To address the public health issue of work-related stress and its detrimental effects on cardiovascular health, future research should prioritize the use of longitudinal studies to identify the mechanisms underlying this association,” says first author Dr. Oluseye Ogunmoroti, of Emory University and senior author Dr. Erin Michos, of Johns Hopkins University, in a statement. “Additionally, conducting thorough workplace intervention studies is essential for the development and implementation of effective stress management strategies that can enhance employee well-being and improve cardiovascular health.”

Perhaps it’s time for both employers and employees to take a heart-to-heart look at workplace stress. After all, a less stressful work environment might not just be good for morale – it could be good for the heart too.
