Stress and Heart Disease

More research is needed to determine how stress contributes to heart disease.  But stress may affect behaviors and factors that increase heart disease risk: high blood pressure and cholesterol levels, smoking, physical inactivity and overeating. Some people may choose to drink too much alcohol or smoke cigarettes to “manage” their chronic stress, however these habits can increase blood pressure and may damage artery walls.
A stressful situation sets off a chain of events. Your body releases adrenaline, a hormone that temporarily causes your breathing and heart rate to speed up and your blood pressure to rise. These reactions prepare you to deal with the situation — the “fight or flight” response.

When stress is constant, your body remains in high gear off and on for days or weeks at a time. Although the link between stress and heart disease isn’t clear, chronic stress may cause some people to drink too much alcohol which can increase your blood pressure and may damage the artery walls.
