Death is a serious matter and…so is cheating. Now it seems that the two may linked through the heart, literally. That’s right folks, according to new studies, adultery is bad for the heart.

Liaisons away from home and with younger women are particularly dangerous. The warnings come from Italian researchers who reviewed previous studies on the causes of infidelity and its effects.


Men are more likely to have heart attacks while having sex with their mistress, not their wives.




The studies showed that ‘sudden coital death’ is far more common when a man is sleeping with his mistress than with his wife. The researchers are still considering the causes of this. Theories include:

  • Stress.
  • Guilt.
  • Performance anxiety.

The review’s authors, from the University of Florence, began by scouring medical literature for research papers including the words ‘unfaithfulness’, ‘extramarital affairs’, ‘infidelity’ and ‘men’.

This provided information about the type of man who is unfaithful and the potential consequences. The analysis showed that heart attacks, including fatal ones, were relatively rare when a man was having sex with his wife at home. But when he started to play away, the dangers grew.


German studies show that most men who died during sex were having an affair.


Furred-up arteries were blamed for more than a third of the deaths, the physical demands of sex are said to cause the fatty plaque that has built up inside arteries to rupture (yet another reason why moderate exercise is good for your sex life).

Heart attacks were the next biggest cause of death, according to the Journal of Sexual Medicine. The stress of wining, dining and satisfying a woman who is likely to be younger than the man’s wife may also be to blame, as can the strain of keeping an affair secret.

Researcher Dr Alessandra Fisher said:

‘Extra-marital sex may be hazardous and stressful because the lover is often younger than the primary partner and probably sex occurs more often following excessive drinking and/or eating. ‘It is possible that a secret sexual encounter in an unfamiliar setting may significantly increase blood pressure and heart rate, leading to increased oxygen demand.’


Think about that the next time you’re considering cheating on your significant other.
