I’m not sure that we actually needed more evidence, but this is pretty compelling.
One of the problems with tying chronic stress and stressful events to heart attack and stroke is that the chemical markers associated with stress are usually gone by the time anyone starts looking for them after a heart attack or stroke.

But research conducted by Dr. Gideon Koren and Stan Van Uum of the University of Western Ontario shows that our hair stores a record of these markers and can provide an accurate history of stress in our lives and especially stressful events that lead to heart attack and stroke.

There is now a mountain of evidence demonstrating the link between the epidemic of chronic stress and any number of maladies such as anxiety and panic attack, heart disease and high blood pressure, reduced immune function, sexual dysfunction, weight gain, cholesterol, (etc, etc, etc) that we all should be taking it very seriously.

You might just find that you are getting addicted to the cure. Breathe. Exercise. Sleep. Spend time with the people you love and doing the things you love. If definitely beats the alternative.
