A new study has revealed just how much sex couples need to have a happy relationship and it is not what you expect
A new study has found that couples are at their happiest when they are having sex just ONCE-a-week.
A Mirror Online report shows that the research suggests that those who hop into bed more frequently get no noticeable benefit from it - in terms of a stable relationship.
The findings, from research conducted by the University of Toronto-Mississauga in Canada, challenge the popular notion that when it comes to sex, the more you have the better.
Scientists analysed data collected at three time points over 14 years from more than 2,400 married couples.
Couples reported increasing satisfaction with their relationships as sexual frequency increased up to once a week. Having sex more often than that showed no noticeable benefit.
Lead researcher Dr Amy Muise, from the university, said: "Although more frequent sex is associated with greater happiness, this link was no longer significant at a frequency of more than once a week.
"Our findings suggest that it's important to maintain an intimate connection with your partner, but you don't need to have sex every day as long as you're maintaining that connection."
The study did not establish whether sex made couples happier, or whether being in a happy relationship led to more sex.
No association was found between sexual frequency and well-being in single people, said Dr Muise. The findings were specific to people in romantic relationships.
Once-weekly sex tended to be the typical frequency rate for established couples, according to the research published in the journal Social Psychological and Personality Science.
Dr Muise added: "Our findings were consistent for men and women, younger and older people, and couples who had been married for a few years or decades."
