Having a marriage that is strained can lead to health conditions that increase a woman’s risk of heart disease. The stress from relationship woes can lead to high blood pressure, increased cholesterol, and obesity. This combination of symptoms are a recipe heart disease, and a good reason to find a way to resolve problems in a marriage, though counseling if necessary.
In contrast, marital strife doesn’t affect men in the same way. The research on this subject appears to indicate that women are more sensitive to emotional strife in their relationships than men are. (Most married women would likely agree with that idea.)
