Having sex just once a week will make you happiest, say experts

More time for Netflix.

If you're in a relationship, the best thing you can do for your happiness is to have a shag once a week.

But while frequent sex has been associated with greater happiness, the correlation peters off at more than once a week.

So doing it more than that might be fun, but probably won't impact your overall happiness.

Great news for those couples struggling to squeeze a quick one in between box sets.

Just under 2,500 couples were involved in the research, by scientists at the University of Toronto-Mississauga, over a 14 year period.

Lead researcher Dr Amy Muise 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 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.”

She explained that the findings were consistent over different age groups and lengths of relationships.

However she did admit that they weren't yet sure whether sex increased happiness in relationships or whether the sex happened because the relationship was already happy.

Another study also found that regular sex was more vital for happiness in relationships than how much money partners earned. Worth remembering next time you're arguing about who last paid for the shopping.

Either way, hopping between the sheets once a week doesn't sound like bad relationship insurance to us.
