An impressive amount of research has linked frequency of sex with greater happiness.
One study even put a monetary estimate on it. They said that the happiness spurt from having sex once a week compared with monthly is similar to the boost you’d get from earning an extra $50,000 a year (though for anything more frequent than weekly sex, the benefits seemed to tail off).
Asking if and why more sex makes us happier may sound like asking the blindingly obvious, but of course a lot of pleasurable activities don’t have long-term emotional benefits; it’s also tricky to rule out the simple alternative possibility that we’re more likely to have sex if we’re happy.
In a series of studies in Personality and Social Psychology Bulletin, psychologists in Switzerland and Canada have looked beyond the immediate bliss that sex can bring, and they say that the main reason that more sex seems to contribute to greater long-term happiness is because of all the cuddling (and other expressions of affection) that’s involved, both at the time, and for hours afterwards.
