Job Stress Can Nearly Double Women's Heart Risk - CBS News (article link)

What they found is that those who had a higher degree of job strain actually were at 40% increased risk for overall cardiovascular disease; 88% had an increased risk for heart attack.

"Job strain for this study included people who felt they were in jobs with little or no decision making, they were very demanding jobs, and in particular didn't allow them to use their individual creativity."

"all of that stress can lead to a reduction in your immune system, it causes chronic inflammation with short-term and long-term consequences and this study really shows that."
