During the 2006 Fédération Internationale de Football Association (FIFA) World Cup, held in Germany, Wilbert-Lampden and colleagues (2006) examined the relationship between emotional stress and the incidence of cardiovascular events. They found that viewing a stressful soccer match more than doubled the risk of an acute cardiovascular event. The risk appeared to be higher amongst men with known coronary heart disease.
This might be a good time to apply a relaxation exercise!
