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.

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.

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 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 brisk walking, jogging, or other activities that make them breathe hard live longer and have fewer heart-related deaths than those who are mostly inactive.
