According to psychologists, people who immediately put an object back in its place after using it often share this trait.

But what does psychology tell us about these women who immediately put things away after moving them? Where does this habit come from? Does it require constant effort? Researchers have investigated the subject...


We all know that woman who invites us over and, as soon as our glass is empty, grabs it and puts it in the dishwasher without even asking if we want to keep it for another drink later. Annoying to some, amusing to others, she can nevertheless boast of having a perfectly tidy home and, above all… of being much less stressed than most people, if we are to believe the experts.

 


In 2010, American psychologists Darby Saxbe and Rena Repetti published a study in the journal Personality and Social Psychology Bulletin examining the link between women's perceptions of their homes and their stress levels. They visited 60 American couples where both partners worked and allowed themselves to be guided through their homes, noting each partner's comments as they gave tours. The team then analyzed saliva samples from the participants.

The results? Women who described their homes as cluttered or a construction site showed a less pronounced daily decrease in cortisol, a profile associated in medical literature with chronic stress. Conversely, in those who described a peaceful home, the stress hormone decreased normally in the evening. The scientists also observed a more pronounced depressive mood in women whose homes were described as messy. In men, however, no clear link was found.

 

Actions performed on autopilot

But in their partners, the associations persisted even after accounting for marital satisfaction and neuroticism. Therefore, although the study sample size is small, the researchers suggest that a home environment perceived as cluttered or unfinished could be associated with poorer physiological and emotional recovery after a workday.

But do these women, who keep their homes so meticulously tidy, make an effort when they put everything away at lightning speed?

 

From a cardiovascular standpoint, animal studies show that chamomile extracts lower systolic and diastolic blood pressure and reduce heart rate. Some extracts inhibit angiotensin-converting enzyme (ACE), the target of many hypertension treatments, and relax vascular smooth muscle. When stress activates the sympathetic nervous system, blood pressure rises; by bringing the body back to a resting state, the plant can make high blood pressure less unstable, although it is not sufficient to correct it on its own.

 

In two studies jointly published in 2002 in the Journal of Personality and Social Psychology , psychologist Wendy Wood asked participants to record their activities, thoughts, and emotions hour by hour in their dashboards. She also observed that between 35% and 43% of the actions performed were habitual—gestures repeated almost daily in the same place.

When participants performed these actions, they tended to think about other things: they acted automatically and reported less stress than when undertaking a new action. This is because new behaviors, or those performed in changing contexts, required more thought and concentration, as individuals had to reflect more deeply.

 

 


What about habits?

Thus, we can conclude that habits serve a cognitive economy and stress regulation function. Those who tidy up immediately would therefore act more automatically than voluntarily, and this automatic behavior would have been established by the force of habit.

But a habit is something that is built up. However, contrary to the famous saying "It takes 21 days for a new habit to become established", the reality is quite different.

According to a study conducted by the University of South Australia and published in the journal Healthcare in December 2024, it appears that a habit takes several months to form, sometimes even almost a year. In their research, the scientists recorded median times of 59 to 66 days, averages of 106 to 154 days, and individual estimates ranging from four to 335 days
