Researchers from the University of Western Ontario in Canada conducted a questionnaire survey on the living conditions of nearly 50000 adults across the country. The results showed that those couples who shared the housework were happier than those who only had their wives or husbands do the housework. Moreover, researchers estimate that the ideal state of a happy life between couples is that neither of them should undertake more than 60% of the housework.

According to this conclusion, in traditional families, when the husband goes out to work, the wife does housework and takes care of the children at home, the degree of marital happiness is relatively low. In this kind of marriage, the husband will feel more pressure, while the wife lacks the sense of achievement because she can't bring economic income to the family. Wives without income will also feel more vulnerable.

In another kind of marriage, when the wife goes out to make money and the husband takes care of the family, problems will also arise. Because the husband will be unhappy and unhealthy, the wife will feel too much pressure.

According to the results of this study, families that share housework on average are the happiest. Rod Boro, the scholar who led the research, pointed out that these research results showed the value of providing equal opportunities for men and women in the workplace and in the family, and also reflected the benefits of men taking a proactive attitude in housework.

Frank Freddy, a sociology professor at the University of Kent in the UK, believes that this study shows that it is very important for couples to have something in their lives that can make them feel independent and successful. In addition, if they can do some things together, such as housework or taking care of children, they will create a bond of intimacy, communication, warmth and mutual trust.
