If you’re looking for a productive way of making more cash, it seems along with the obvious benefits of a tumble in the sack, you could score a fatter paycheck. A study published in the International Journal of Manpower has proven that people who have sex four or more times a week tend to make more money than those with a quieter sex life. Analysing data from 6,317men and women, researchers from the Institute on the Study of Labour in Germany looked at the frequency of the male and female respondents’ sex lives and their monthly wages. Breaking down the figures, people who claimed to have sex four or more times a week earned almost 5 per cent more than those who were less likely to have a rumble in the sheets. Study author Nick Drydakis, Ph.D., and senior lecturer in economics at Anglia Ruskin University suggests that the results could reflect the fact that having more sex boosts your overall health and mood – which can increase your work productivity. Speaking to Women’s Health, sex educator Yvonne Fulbright also points to the fact that those who earn a higher wage are less likely to stress about money – which can cause major complications and concerns in a relationship. Acting as a dampener on those flames of passion. So whether it’s just a simple coincidence, or you notice your bank account benefiting from your bedroom behaviour, it’s not the worst study to try at home for yourself.
