I am a 55-year-old on high blood pressure medications, and my wife asked an interesting follow-up question: Are we better off having sex in the evening rather than in the morning if heart attacks and strokes are more likely to occur in the morning?
However, there does not seem to be an increase in risk from morning exercise versus exercise at any other time of the day.
While regular exercise reduces the risk of having a heart attack, extreme levels of exertion -- especially in sedentary, high-risk men -- can precipitate heart attack or stroke.However, moderate exercise, such as from sexual activity, does not increase risk of a heart attack.
