Research suggests a consistent link between tidy living spaces and lower stress, better focus, and improved sleep quality. Studies from UCLA, Princeton, and DePaul University have found that clutter is associated with elevated stress hormones, reduced cognitive performance, and lower life satisfaction. For Calgary households (where long winters mean five or more months spent predominantly indoors), the condition of your home environment may shape your day-to-day wellbeing more than you’d expect.
Here’s what the research actually says, what it doesn’t say, and what you can do about it.
There’s a growing body of research connecting home environments to mental health outcomes. These are the most widely cited studies, along with what they actually found.
In 2010, researchers Darby Saxbe and Rena Repetti at UCLA studied 60 dual-income couples in Los Angeles. Participants gave self-guided tours of their homes, describing what they saw in their own words.
The researchers analyzed these descriptions using linguistic software, looking for patterns in how people talked about their living spaces. Women who used more clutter-related language (words like “mess,” “disorganized,” and “chaotic”) when describing their homes showed flatter cortisol slopes throughout the day. Cortisol is a stress hormone that normally peaks in the morning and declines throughout the day. A flatter slope is associated with poorer health outcomes and chronic stress.
Women who described their homes in more restorative terms (“restful,” “organized”) showed steeper, healthier cortisol patterns. The effect was stronger for women than men. The study was published in Personality and Social Psychology Bulletin.
It’s worth noting: this was a relatively small sample of dual-income couples in one city, and the relationship was correlational. The study showed that clutter descriptions and stress biomarkers went together, not that one caused the other.
Sabine Kastner, a psychology professor at Princeton Neuroscience Institute, has spent over 20 years studying how the brain processes visual information. Her fMRI research consistently shows that visual clutter competes with the brain’s ability to focus.
When subjects in her studies focused on one object while other objects were present in their visual field, brain scans showed the brain processing a fuzzy version of each distractor. The more objects present, the harder the brain had to work to filter out irrelevant information, reducing the cognitive resources available for the actual task.
In practical terms: when your visual environment is cluttered, your brain is spending energy managing all that input before it even gets to the thing you’re trying to concentrate on.
In 2016, psychologist Joseph Ferrari at DePaul University surveyed more than 1,300 adults across the United States and Canada. His research, published in the Journal of Environmental Psychology, found that participants who reported higher levels of household clutter also reported lower levels of life satisfaction and psychological wellbeing.
Ferrari’s work also found that clutter negatively affected what he called “psychological home,” the feeling of belonging and comfort in your own space. More clutter was associated with a weaker sense of attachment to one’s living environment.
NiCole Keith, an associate professor at Indiana University, studied 998 adults between the ages of 49 and 65 in St. Louis. Her research examined which environmental factors predicted physical activity levels.
The surprising result: interior home condition was the only significant predictor. Not the neighborhood, not traffic patterns, not access to parks. Just the state of the home itself. People with cleaner, more organized homes were more physically active.
Keith noted that the relationship could run in either direction: physically active people may also tend to keep tidier homes, or a clean home environment may reduce friction against movement. Either way, the correlation was the strongest environmental factor in the study.
Before drawing conclusions, it’s important to be honest about what these studies don’t prove.
Most of this research is correlational. A cluttered home doesn’t “cause” depression or anxiety in the way that a virus causes an infection. The relationship likely runs in both directions: people experiencing low mood or high stress may have less energy to maintain their space, and a cluttered space may contribute to continued stress. Untangling which comes first is genuinely difficult, and most of these studies don’t attempt to.
A clean home is not a treatment for clinical conditions. If someone is dealing with depression, anxiety, or other mental health challenges, a tidy kitchen is not a replacement for professional support. The research suggests that your environment can support how you feel — not that it can fix how you feel.
The studies have real limitations. Saxbe and Repetti studied 60 couples. The Florida State mindfulness study (discussed below) had 51 participants. These are small samples. Ferrari’s study was larger (1,300+), but relied on self-reported data. The Indiana University study found a correlation but couldn’t establish directionality. These are meaningful findings, but they’re not definitive proof.
The honest takeaway is more modest than most headlines suggest: your home environment appears to influence your stress levels, focus, and general sense of wellbeing. Small changes to your surroundings can support — not fix — how you feel day to day.
Here’s how the research translates into everyday experience.
This is the Princeton finding in practical terms. If your kitchen counter has 15 items on it and you’re trying to plan dinner, your brain is processing all 15 before it gets to the task at hand. The same applies to a desk covered in papers, an entryway piled with shoes and jackets, or a bathroom counter crowded with products.
This isn’t an argument for minimalism or perfection. It’s about reducing the number of things competing for your attention in the spaces where you need to think clearly. You don’t need an empty countertop. You just need fewer things on it than your brain has to process while you’re trying to focus.
According to the National Sleep Foundation, roughly two-thirds of Americans say that a clean, comfortable bedroom is important for getting good sleep. This is based on consumer surveys rather than clinical sleep studies, so the evidence is softer here, but the pattern makes intuitive sense.
A cluttered bedroom means visual stimulation when you’re trying to wind down. Stale sheets are less comfortable. Dust on surfaces adds to the visual noise in a room that’s supposed to be restful. None of these individually ruins your sleep, but together they create an environment that’s working against rest rather than supporting it.
For Calgarians, this matters more than it might in warmer climates. From November through March, you’re spending 15 or more hours indoors daily. Your bedroom is a larger share of your waking (and sleeping) experience during those months.
A small but interesting study from Florida State University found that mindful dishwashing (focusing on the warmth of the water, the feel of the dishes, the scent of the soap) increased feelings of inspiration by 25% and reduced nervousness by 27%. The study, led by Adam Hanley and published in the Journal of Mindfulness, involved 51 college students, so the sample was small.
The key detail: the benefit wasn’t from having clean dishes. It was from the act of focusing on a simple, repetitive, sensory task. Participants who washed dishes without the mindfulness instruction saw no change in mood.
This suggests that cleaning can be calming, but only when it’s approached as a focused, present-moment activity rather than a frantic catch-up session. Not everyone experiences cleaning this way, and that’s fine. The research supports cleaning as one potential mindfulness practice, not the only one.
During the COVID-19 pandemic, multiple research teams studied the relationship between housing conditions and mental health. The findings were consistent: people who reported higher satisfaction with their living conditions also reported better mental health outcomes during lockdowns. Crowded or poorly maintained living situations were associated with reduced wellbeing.
Calgary’s winters create a similar dynamic, though less extreme. When you’re spending more time indoors, whether because of weather, remote work, or just the season, your indoor environment takes on a larger role in your daily experience.
The same home that feels fine in July, when you spend evenings on the patio and weekends at the park, can feel noticeably different in January, when it’s dark by 5 PM and you haven’t left the house since morning.
The Indiana University finding is worth revisiting here. Interior home condition was the single strongest environmental predictor of physical activity, stronger than neighborhood walkability, access to gyms, or outdoor recreation options.
One possible explanation: a cluttered home creates friction against movement, both physically (navigating around things) and psychologically (the mental weight of unfinished tasks). Another possibility is that the same self-regulation habits that lead to an active lifestyle also lead to a tidy home. The researchers noted the correlation without claiming causation.
Either way, the practical implication is the same: the state of your home and your physical activity levels tend to track together.
Most of this research was conducted in places with milder climates: Los Angeles (Saxbe and Repetti), Florida (Hanley), St. Louis (Keith). Calgary’s reality is different.
Long winters mean more indoor hours. From roughly November through March, most Calgarians spend the majority of their time inside. December daylight in Calgary is around 8 hours, meaning most of your waking time is spent indoors under artificial light. Your home isn’t just where you sleep. It’s where you eat, work, exercise, and spend most of your leisure time for five months of the year.
Chinook weather swings keep things unpredictable. Calgary’s signature Chinook winds can shift temperatures by 15 to 20 degrees in a matter of hours. These swings can keep people housebound on days they expected to be outside, and they blow dust, dirt, and debris into homes more aggressively than a typical winter wind.
Seasonal energy dips are common. Calgary’s northern latitude means less sunlight during winter months, and many residents notice lower energy and motivation during this period. If maintaining your home already takes effort, winter makes it harder. That can feel like a cycle: lower energy may mean less upkeep, which can add to the sense of being overwhelmed.
The spring reset matters. After five to seven months of heating season (dry air, closed windows, tracked-in snow and salt), Calgary homes accumulate more than homes in temperate climates. A thorough spring clean at the end of winter is one of the highest-impact resets you can do, both for your home and for how you feel in it.
You don’t need to Marie Kondo your entire house this weekend. Small, targeted changes tend to have a disproportionate effect on how your space feels.
Kitchen counter, entryway, coffee table. These are the first things you see when you walk into a room, and they set the tone for how the whole space feels. Clearing three high-visibility surfaces creates a noticeable sense of order without requiring you to reorganize closets or tackle the garage.
If your kitchen counter currently has 20 items on it, getting it down to 8 will feel dramatically different. Perfection isn’t the goal. Just fewer things competing for your attention.
It takes two minutes. The research aside, it’s the single highest-return tidying habit because you see the result every time you walk past your bedroom. An unmade bed makes the whole room feel undone. A made bed makes it feel managed.
This isn’t a moral obligation. It’s a low-effort action with outsized visual impact.
If your sleep has been off, focus your effort here before anywhere else. Clean sheets, a clear nightstand, and minimal visual clutter near the bed. The National Sleep Foundation data suggests most people notice a difference in how they sleep when their bedroom is clean and comfortable.
In Calgary’s winter, when you’re going to bed in the dark and waking up in the dark, your bedroom environment matters even more. It’s the first and last thing you experience each day.
Ten minutes of daily tidying prevents the accumulation that triggers the “where do I even start” overwhelm. A sink with today’s dishes feels manageable. A sink with a week’s dishes does not.
The same applies to laundry, mail, and general surface clutter. Small daily maintenance is psychologically easier than periodic large catch-ups, and it keeps your space in a state that supports rather than drains you.
Difficulty maintaining your home can be a sign that something bigger is going on: stress, exhaustion, burnout, depression. If you’re in a stretch where cleaning has completely fallen off and you can’t seem to start, that’s worth paying attention to, not beating yourself up about.
One practical option: a recurring cleaning service takes that task off your plate entirely while you focus on whatever is demanding your energy right now. This isn’t a sales pitch disguised as advice. It’s an acknowledgment that sometimes the most useful thing you can do is stop trying to do everything yourself.
If your home has gotten away from you, whether because of a busy season at work, a new baby, a health issue, or just a long Calgary winter, a professional clean can reset things without requiring you to find the energy and time to do it yourself.
A one-time first time clean works as a reset. It covers everything a standard clean does, plus detailed work on baseboards, door frames, under furniture, and furniture surfaces. It takes a home that’s fallen behind and brings it back to a baseline that’s much easier to maintain.
From there, a recurring standard clean (weekly, biweekly, or monthly) keeps things maintained so you’re never back in catch-up mode. The goal isn’t a perfect home. It’s a home that doesn’t add to your stress.

Research suggests a link. A 2010 UCLA study by Saxbe and Repetti found that women who described their homes using clutter-related language showed higher cortisol (a stress hormone) throughout the day. A 2016 DePaul University study of more than 1,300 adults found that clutter was associated with lower life satisfaction and reduced psychological wellbeing.
These are correlations, not proof that cleaning eliminates stress. But the pattern is consistent across multiple studies from different institutions and different sample sizes. Your home environment appears to influence your stress levels, even if the exact mechanism isn’t fully understood.
Yes. Research from Princeton Neuroscience Institute, led by Sabine Kastner, found that visual clutter competes for your brain’s attention. When there are more objects in your visual field, your brain has to work harder to filter out irrelevant information, reducing the cognitive resources available for the task you’re actually trying to do.
This applies to home offices, kitchens, living rooms, and any space where you need to think clearly. Reducing visual clutter in your primary work or living space can free up cognitive capacity for the things that actually matter.
Not necessarily. The relationship between clutter and mental health runs in both directions. People experiencing low mood or depression may have less energy to maintain their space, and a cluttered environment may contribute to continued stress. It’s often a cycle rather than a one-way cause.
A messy home on its own is not a diagnostic indicator of any condition. If you’re concerned about your mental health, speaking with a healthcare professional is the right first step — not reorganizing your closet.
The National Sleep Foundation reports that roughly two-thirds of Americans say a clean, comfortable bedroom is important for getting good sleep. While this is based on self-reported preferences rather than clinical sleep data, it aligns with broader research showing that your physical environment influences sleep habits.
Keeping your bedroom tidy, your sheets fresh, and visual clutter minimal near the bed is a low-effort step that many people find makes a noticeable difference. During Calgary’s long winters, when bedroom time is a larger share of your day, this is especially worth prioritizing.
Princeton researchers found that visual clutter forces your brain to distribute attention across more objects, reducing your capacity for the task you’re actually trying to do. When that effect compounds across an entire room, or an entire home, the cognitive load can feel paralyzing, especially if you’re already tired or stressed.
This is why the advice to “just clean up” can feel unhelpful when you’re overwhelmed. Starting with one small area — a single countertop, a nightstand, or a bathroom sink — is often more effective than trying to tackle everything at once. One clear surface creates momentum; a whole-house plan creates paralysis.
A cleaning service removes a recurring task from your plate, which can reduce stress and free up time and energy for other priorities. It’s not a substitute for professional mental health support, but for people who find that household maintenance is adding to their stress, outsourcing that task is a practical step.
At NeatNow, a standard clean starts at $130 for a studio or 1-bedroom home in Calgary. Many clients find that a biweekly or monthly clean is enough to keep things manageable, especially during winter, when energy and motivation tend to be lower. You can get a quote here.
Calgary residents spend significantly more time indoors from November through March, with some of the shortest daylight hours in Canada during December. When your home is where you spend the majority of your waking hours, the condition of that space has a larger impact on your daily experience than it would in a city where you’re outside year-round.
Winter also brings specific challenges: dry heated air circulates more dust, tracked-in snow and salt accumulate on floors, and Chinook winds blow fine particulate into homes. A seasonal deep clean in spring, or a recurring service through winter, helps keep your indoor environment in a state that works for you rather than against you.
Your home doesn’t need to be perfect. But if the state of your space has been weighing on you, sometimes the most practical step is the simplest one. You can get an instant quote online in about 60 seconds, or call us at 587-325-8281.
