Sexual activity can directly cause death, particularly due to coronary circulation complications, which is sometimes called "coital death," "coital sudden death" or "coital coronary." However, coital deaths are significantly rare. People, especially those who get little or no physical exercise, have a slightly increased risk of triggering a heart attack or sudden cardiac death when they engage in sexual intercourse or any vigorous physical exercise that is engaged in on a sporadic basis. Regular exercise reduces, but does not eliminate, the increased risk.
