A study conducted by Carnegie Mellon University in Pittsburgh, Pennsylvania, revealed that it’s a common misconception that having more sex will make you happier.

Even though many studies have shown evidence that suggest there is a link to sex and happiness, researchers from the university say that other factors besides making love, such as income, location and age, also contribute to our mood.

George Leowenstein, a professor of economics and psychology at the university, said: “Although it seems plausible that sex could have beneficial effects on happiness, it is equally plausible that happiness affects sex… or that some third variable, such as health, affects both.”

The scientists team conducted a 90-day experiment  asking 64 married couples between the ages of 35 and 65 to rate their sex life, as The Sun says.

They split them into two groups. One group would have more sex and the other group would not have to change nothing about their sex life.

Then they analysed the results by comparing how happy they were afterwards.

The team said: “Contrary to what one would expect if the causal story running from sexual frequency to happiness were true, we observed a weak negative impact of inducing people to have more sex on mood.”

Couples who had twice the amount of sex than usual didn’t enjoy the love-making as much and were less happy overall, which means that more steamy sessions under the sheets do not make us happier.

“You should concentrate on quality and not quantity if you want to be happy”, the professor told The Times.
