A cluttered interior is not just a storage problem. Research in environmental psychology is beginning to document the concrete effects of domestic disorder on perceived stress and sleep quality, far beyond mere visual annoyance. Transforming a messy home into a serene space requires understanding these mechanisms before touching any furniture.
Visual clutter and mental load: what research documents
A 2023 study conducted by the University of New South Wales (Australia), published in the Journal of Environmental Psychology, establishes that the perception of domestic chaos increases perceived stress and fragments sleep, regardless of the size of the dwelling. This point deserves attention: living in a large cluttered apartment offers no measurable advantage over a small organized home.

Visual clutter in the bedroom weighs down cognitive load before bedtime. The brain continues to process visual stimuli (piles of clothes, objects piled on the nightstand) even when trying to relax. The result is slower falling asleep and lower quality sleep.
This link between the domestic environment and mental health remains underexplored in typical content about interior decoration, which focuses on color or material choices. Before rethinking the aesthetics of a living space, one must first explore the solutions from Conseil Habitat for structuring a decluttering process that lasts.

Sustainable decluttering: renting as an underestimated lever
The classic reflex in the face of clutter is to sort, throw away, or give away. This approach works, but it does not address the cause: accumulation often resumes a few months later because the same bulky and rarely used items tend to return.
Since 2023, a trend called “home as a service” has proposed an alternative. Ikea is testing furniture rental offers in several European countries. Leroy Merlin is experimenting with tool subscription services. The principle is simple: stop owning items that are rarely used.
Which items are prioritized
- Secondary appliances (steam cleaner, raclette machine, drill) that occupy entire closets for just a few hours of use per year
- Modular or seasonal furniture (occasional table for holidays, folding guest bed) that can be borrowed or rented temporarily
- DIY and gardening tools, of which most households only use two or three pieces regularly
This approach mechanically reduces the volume of items stored in the home. It requires a change in mindset: accepting not to own everything, which remains a barrier for many households. Field reports vary on this point, with some users reporting a real liberation of space, while others find the logistics of renting cumbersome on a daily basis.
Sorting clothes and personal items: method by zone rather than by category
Most organizing guides recommend sorting by category (all clothes first, then books, then papers). This method, popularized by several bestselling books, has a flaw: it forces the gathering of scattered items throughout the house, creating even more anxiety-inducing temporary disorder.
Working room by room limits the feeling of overwhelm. Start with a small area (a closet, a shelf), complete that perimeter before moving on to the next. The result is immediately visible, which helps maintain motivation.
The three destination rule
For each item taken out of storage, there are only three options:
- It stays in its current place because it is used at least once a month
- It is moved to secondary storage (basement, attic) with a review date set for six months: if it hasn’t been retrieved by then, it goes
- It leaves the house immediately (donation, sale, recycling)
This system avoids decision paralysis. The classic decluttering trap is creating a fourth mental category, “I don’t know yet,” which becomes a permanent pile.
Interior layout and energy flow in the space
Once the volume of items is reduced, the question of layout arises differently. A poorly arranged decluttered space remains a source of stress, because circulation is hindered or certain areas become unused dead zones.
The basic principle can be summed up in one sentence: every square meter must have an identifiable function. A corner of the living room without a specific use tends to accumulate transitional items (mail, bags, chargers). Assigning it a role, even a simple one (reading nook, plant space), prevents this drift.
Natural light and perception of space
Natural light alters the perception of available volume. A dark interior appears more cluttered than it is. Clearing the area around windows, removing opaque curtains in favor of light sheers, and positioning a mirror facing a light source are low-cost interventions that change the sense of space.
The available data do not allow for precise quantification of the well-being gain related to brightness, but the correlation between natural light and reduced anxiety is regularly observed in environmental psychology studies.
Transforming a messy house into a place of serenity does not come from a decorative makeover or a one-time deep clean. The sustainable lever lies upstream: reducing the flow of incoming items, structuring sorting by manageable zones, and assigning a clear function to each space. The rest, colors and materials, comes later, when visual calm is already established.
