London, April 22 (IANS): To earn better at the workplace, what qualities do you think you must have? Well, for one, start having extra action between the sheets!

According to a recent study, employees who make love two or three times a week earn 4.5 percent more than their peers who are laggards in this department.

Researchers from the Anglia Ruskins University, a public university located in Cambridge, East of England, also found that workers with health problems who are sexually active earn 1.5 percent more than those with similar ailments who are not sexually active.

The team looked at responses from 7,500 individuals to a behavioural study by universities in Greece to analyse the effect of sexual activity on wages.

Study leader and economist Nick Drydakis found that the more often the participants had sex, the more they were likely to earn.

According to researchers, it is important to gain knowledge of the factors that can positively or negatively affect your sexual activity.

Sexual activity can be seen as "a barometer for health, quality of life, well-being and happiness".

"The happier and more fulfilled individuals are in their lives, the more productive and successful they will be in their work, translating to higher wages," the team added.

In the absence of these elements, people may become susceptible to loneliness, social anxiety and depression -- all factors that can affect their working life.

The team also found that those with heart problems, such as coronary heart disease and angina, are a whopping 11.4 percent less sexually active, the study found.

The paper is set to be published in the International Journal of Manpower.
