Does Decluttering Actually Reduce Stress?

Direct answer: Yes, with an important caveat: cluttered homes are consistently linked to real stress markers, including disrupted cortisol patterns and lower life satisfaction, in published psychology research. But most of this evidence is correlational, not experimental, so decluttering itself has not been proven to cause stress relief, even though a calmer home reliably correlates with a calmer mind.

What the Real Research Actually Shows

The most-cited study here is Darby Saxbe and Rena Repetti’s 2010 paper in Personality and Social Psychology Bulletin, “No Place Like Home: Home Tours Correlate With Daily Patterns of Mood and Cortisol.” Sixty dual-income spouses gave self-guided video tours of their homes, and researchers used linguistic analysis software to score how much each tour’s language described clutter and unfinished projects versus calm, restorative features. Over the following three weekdays, wives whose tours scored higher on “stressful home” language showed flatter diurnal cortisol slopes, a pattern linked to worse long-term health outcomes, and more depressed mood across the day. Wives with more “restorative home” language showed healthier, steeper cortisol slopes.

These effects held after controlling for marital satisfaction and neuroticism, which matters because both of those factors could otherwise explain away the clutter-stress link on their own. Notably, the effects were weaker or absent in husbands, a detail that popular decluttering advice rarely mentions when it cites this study as blanket proof that clutter causes stress for everyone.

A more recent study, published in 2025 in the Journal of Environmental Psychology, used structural equation modeling and found a similar pattern: people who perceived their homes as more cluttered reported lower well-being, lower life satisfaction, and more negative affect. What makes this study useful is that it also tested why. The relationship was partly explained by how cluttered homes made people feel about their home’s beauty, not by clutter volume alone. In plain terms, a room that feels ugly because of its mess appears to do more psychological damage than the sheer quantity of stuff sitting in it.

Why “Decluttering Cures Stress” Overstates the Science

Both studies above are correlational. They measured existing homes and existing stress patterns at a single point in time, not what happens when someone actually declutters. Saxbe and Repetti’s design was a snapshot of language and cortisol, not a before-and-after intervention, so it shows that clutter and stress travel together. It does not show that removing clutter is what lowers stress.

Dr. Joseph Ferrari of DePaul University makes a related point worth taking seriously, in an APA “Speaking of Psychology” interview: ordinary household clutter is a distinct phenomenon from clinical hoarding disorder. The research linking clutter to lower life satisfaction and higher depression risk describes an association, not a diagnosis, and not a guaranteed cause. A messy kitchen counter and clinical hoarding sit at very different points on a spectrum, and treating them as the same problem does a disservice to both.

Popular decluttering content often skips this distinction and implies that tidying is a proven mental-health treatment, the kind of claim that sells books and courses but outruns what the underlying studies actually measured. The honest read is that a messier home and a more stressed household tend to show up together, for reasons that likely run in both directions. Stress makes it harder to tidy in the first place, and clutter adds its own visual and cognitive load on top of whatever stress already existed. Untangling which came first is exactly what correlational research cannot do.

The Follow-Up Question: Does Actually Decluttering Lower Stress?

This is the natural next question, and the evidence here is thinner than the correlational findings above. A handful of small intervention trials exist. One example is a randomized, open-label trial run in Japan that tested a decluttering-and-organizing workshop against a control condition, among people who already reported difficulty decluttering, to see whether structured help changed clutter-related distress.

Studies like this are useful early signals, but they come with real limitations worth naming plainly. The samples are small and self-selected, meaning participants already struggle with clutter and already want help with it, which is a very different starting point from a random member of the general public. Follow-up periods are short, and none of this work has been replicated at scale with rigorous, longitudinal designs that could actually establish cause and effect over time.

The fair conclusion for a family audience is a modest one. Decluttering is a reasonable, low-risk thing to try if a messy home is bothering you or your household, and it lines up with what the correlational research would predict. But it should be framed as a plausible, common-sense habit worth testing for yourself, not as a scientifically proven stress cure. If clearing a countertop or a closet makes your home feel calmer, that is a legitimate reason to keep doing it. It just is not the same thing as a clinical treatment with an established evidence base behind it.
