Even if you exercise regularly in your free time, having a very physically demanding job can still make your risk of dying from heart disease more than six times higher than someone with a less active job.

Even if you work out at the gym or go for runs after work, having a job that requires heavy physical labor might still be bad for your health — which is the opposite of what most people expect.

People with very physically demanding jobs, like lifting heavy things all day, are more likely to die from heart problems than people with less active jobs — even if they exercise in their free time.

If you’ve never smoked but have a very physically demanding job, your risk of dying from heart disease is more than three times higher than someone with a less active job — even if you’re otherwise healthy.

People who do physically demanding jobs, like construction or farming, may be more likely to die sooner than people with less physically demanding jobs — especially if they’re younger or women.

People who move more—especially those who do brisk walking, running, or other intense activities—tend to have fewer heart problems, and this benefit is even stronger for people who are already at high risk for heart disease.
