The University of Nevada found that infidelity could severely impact your health – both physically and mentally.
They discovered it could lead to the person who was cheated on engaging in more unhealthy behaviour.
This includes unprotected sex, drug use, alcohol use, binge eating, or not eating at all and extreme exercising.
Indeed, 45 per cent of people failed to eat enough, while 44 per cent abused alcohol and 29 per cent over-exercised.
They concluded that because cheating can cause feelings of partner blame, self-blame, and causal attribution, it can in turn indirectly trigger health compromising behaviours.
Unsurprisingly, the study showed that being cheated on could have a significant impact on your mental health.
Victims tended to suffer depression, anxiety and distress too.
Shrout said: “Being cheated on seems to not only have mental health consequences, but also increases risky behaviours.
“We also found that people who blamed themselves for their partner cheating, such as feeling like it was their fault or they could have stopped it, were more likely to engage in risky behaviours.”
While the reasons for these side-effects are unclear, it’s thought it could be due to damaged self-esteem, lower inhibitions towards risky behaviours, or retaliation towards the cheating partner.
Women were more likely to engage in this unhealthy behaviour after being cheated on than men.
