Infidelity has long been a subject of interest for poets, novelists, songwriters, filmmakers, and scientists alike. Scientists have made several discoveries about cheating, including the potential role of genetics.
According to some findings, women whose mothers cheated are more likely to cheat themselves, and similarly, men whose fathers cheated are more likely to cheat. Additionally, individuals with a particular variant of the DRD4 gene are more likely to engage in uncommitted relationships and exhibit promiscuous and unfaithful behavior.
This gene has also been linked to sensation-seeking behaviors such as heavy drinking and gambling, which can cause a dopamine rush. It is worth noting that having this gene does not excuse cheating behavior, as humans have free will.
Other research suggests that women tend to prefer men with deep voices for short-term relationships but may avoid them when seeking long-term partners due to a subconscious awareness of the potential for infidelity.
Infidelity has also been found to have negative effects on physical health. For instance, men are more likely to experience penile fractures during affairs than with their wives. Furthermore, men who cheat are at a higher risk of heart attacks during extramarital relations, a phenomenon known as sudden coital death.
While the exact reasons for this increased risk are unknown, it is thought that the stress and excitement of an illicit encounter can raise blood pressure and heart rate, making heart attacks more likely.
Other interesting patterns have emerged from research on cheating. For example, men often choose to take their mistresses to anonymous, dimly lit restaurants near hotels, while women who are ovulating and go out without their partners tend to travel farther from home, visit unusual places, and wear more revealing clothing.
The most common time for infidelity to occur appears to be early evenings, mid-week, when it might be least expected.
