If you occasionally find yourself in between the sheets with your partner, chances are you have heard the phrase “I’m too tired,” rated as the most common excuse on the list of ways to avoid sex. On average, American couples, partnered or married, have sex a few times per month to weekly as oppose to more than two to three times a week, reports the Kinsey Institute. Busy schedules, work demands, and in some cases, kids, account for less sex during the week between couples. It’s time to stop singing the same old tune when you want to avoid sex, increasing the frequency of sex during the week can result in big dividends for you and your partner, according to a findings published in July by the Institute for the Study of Labor.

Nick Drydakis, lead author of the study and economics lecturer at Angila Ruskin University in Cambridge, England examined the data of 7,500 people aged between 26 and 50 years old who lived in Greece. The participants of the study were asked about their sexual orientation, age, frequency of sex, education, religion, their employment and how much annual income did they generate. While subjects of the study included heterosexual and homosexual couples, only 5.5 percent reported they were Lesbian Gay Bisexual and Transgender (LGBT).

Overall, working couples who admitted to having sex more than four times a week made approximately five percent more than those who engage in less sexual activity. These couples were also found to be happier and healthier compared to their counterparts which is associated with a positive attitude in a work environment. “People need to love and be loved, sexually and non-sexually,” Drydakis told the New York Daily News. “In the absence of these elements, many people become susceptible to loneliness, social anxiety, and depression that could affect their working life,” he said.

Couples who engage in sexual activity with their partner tend to have more elevated moods than their counterparts because of the spike of serotonin levels during sex. When a partner orgasms, this releases a wave of serotonin to the brain naturally and can account for improved moods post sex. These positive changes in mood can also influence a couple’s personality and health. Drydakis found those who had more sex were more likely to be more social and have lower rates of health issues such as arthritis, cardiovascular disease and diabetes.

Previous studies have examined the relationship between frequency of sex and risk of cardiovascular disease in men. Findings published in the British Medical Journal (BMJ) show men who have sex two to three times a week can reduce their risk of cardiovascular disease by half. For males, an orgasm can lower their blood pressure and as a result lowers their risk of heart disease.

Drydakis and researchers propose that while the connection between sex and money is not exactly identified, it can be tied to the fact that people who are employed make more money and therefore have the financial means to date more often. A person who makes more money can also be physically appealing to others because they are seen as the financial provider that can buy their significant other more gifts. "Higher wages may increase purchase of gifts that are thanked for via sex," said the researchers of the study in the report. The theory of the more money spent, the more sex you get suggests an endless cycle that could be unhealthy and lead to temporary happiness.

It is important to remember the findings only show a link between sexual activity and wages. Having more sex will not get you a raise, but it can motivate you to find a high-paying job.
