Check out this page! Here are a few quotes from it:
A study of men across seven countries found that those who shouldered a bigger share of domestic responsibilities had a better sense of wellbeing and enjoyed a better work-life balance.
Sociologists used data from the regular European Social Survey which compares the lifestyles of people across Sweden, Norway, Denmark, the Netherlands, Germany, France and Britain.
All of the participants are asked standard questions used to measure their happiness or wellbeing such as whether they feel “fulfilled” in life and whether they wake up feeling refreshed.
The researchers expected to find that where men shouldered more of the burden, women’s happiness levels were higher.
In fact they found that it was the men who were happier while their wives and girlfriends appeared to be largely unmoved.
Those men who did more housework generally reported less work-life conflict and were scored slightly higher for wellbeing overall.
So, men, if you wonder why you should do part of the housework at home, don't do it for the sake of your better halves. Do it for yourselves!
