Stress Affects How Blood Vessels Function
Stress increases the risk of developing heart disease and researchers think they have found out why. In a recent study they asked 10 healthy men to defend themselves to an audience against a false charge of shoplifting. In all of the men the stress caused the endothelium, that's the lining of the blood vessels, to function abnormally for at least 4 hours afterwards. The scientists have suggested that abnormal functioning of the blood vessel lining encourages fatty deposits to fur up the vessel, producing heart disease and other problems.
