Researchers in Germany followed 1364 volunteers to see how they allocated their time during the 5456-day survey period. The results showed that overall, participants spent an average of 1 hour and 29 minutes a day doing housework, but those in the highest neurotic group did 24 minutes more than that average. 41 minutes more per day than the most emotionally stable group. The researchers speculate that people with poor emotional stability are more likely to develop anxiety and depression and need a cleaner environment to maintain psychological comfort and sense of security
they spend more time cleaning.
People who like to do housework have poor emotional stability.
