A common notion that having more sex makes people happier has been dispelled by researchers from Carnegie Mellon University.
In fact, what they found, is that more sex can actually make you unhappier.
The team decided to examine the causal relationship that exists between sex and happiness, pondering whether having more sex makes people happy, or does being happy make them have more sex.
They studied 128 heterosexual married couples who claimed to have solid sex lives, and got them to either have more or less sex over a period of three months.
One group was asked to double the amount of sex they had in that period, while the other group had no instructions about frequency and were told to keep their sex lives the same.
Each couple had to fill in a questionnaire about their sexual experienced and their happiness at the end of each day.
They found that the couples who were having sex twice as much as usual enjoyed the sex less – and their levels of happiness decreased over the three month period.
The researchers theory is that being made to have more sex made the couple’s less motivated to have sex over time, and therefore they enjoyed it less. This resulted in a drop in quality of the sex they were having, and this in turn affected their happiness.
