The Science-Backed Benefits of Decluttering for Your Home and Health

In an age of consumerism, our homes often become repositories for more than just the necessities. From gifts we receive to impulse purchases, the accumulation of possessions is a common experience in Western society. While the presence of clutter might seem harmless, a growing body of scientific research suggests it can have a tangible impact on our physical and mental well-being. This blog post explores the evidence behind the benefits of decluttering, transforming your living space into a healthier and more serene environment.

The Link Between Clutter and Stress

The stress of modern life is a significant concern, with one in six people in England experiencing a mental health problem at any given time, according to NHS Digital [1]. Clutter can be a silent contributor to this stress. Research has shown a direct correlation between high levels of clutter and increased cortisol, the primary stress hormone [2]. A cluttered environment can overwhelm our senses, making it difficult to relax and focus. This constant visual stimulus can lead to feelings of being overwhelmed and anxious.

Moreover, the inability to find items when needed adds a layer of time-consuming frustration to our daily lives. A study from the Journal of Environmental Psychology found that a messy and disorganised environment can lead to feelings of dissatisfaction and reduced psychological well-being [3]. Essentially, the more effort we have to expend to navigate our own homes, the more mental and emotional energy we expend, leaving us feeling drained.

Decluttering for a Physically Healthier Home

Beyond the mental toll, clutter can pose a physical health risk. Unused items and packed spaces are prime locations for the accumulation of dust, pet hair, and other allergens. These impurities can contribute to poor indoor air quality, potentially exacerbating conditions like asthma and allergies [4]. By decluttering, you remove the surfaces and hidden nooks where these allergens can gather, making it easier to clean your home thoroughly and efficiently. A tidy, open space allows for better airflow and reduces the presence of dust mites and other irritants, creating a physically healthier environment to live in [5].

Decluttering as a Pathway to Mindfulness and Emotional Wellness

The act of decluttering is not merely about tidying up; it is a mindful practice. The process of deciding what to keep and what to let go encourages you to be present and intentional. This practice forces you to confront your relationship with your possessions, prompting a self-reflective process about what truly holds value in your life today. This can be a liberating experience, as it allows you to release not only physical items but also the emotional baggage and memories tied to them.

Research published in Personality and Social Psychology Bulletin suggests that a sense of control over one’s environment is positively linked to a sense of personal well-being [6]. Decluttering gives you this control, allowing you to curate a space that reflects your current self and aspirations rather than a collection of items from the past.

Practical Tips for an Empirically Healthier Home

Here are five scientifically-informed tips to help you begin your decluttering journey:

1. Start Small to Overcome Paralysis: The overwhelming nature of a cluttered home can lead to “clutter paralysis,” a state of being so daunted that you don’t know where to begin [7]. To combat this, start with a small, manageable area, like a single drawer or a bookshelf. This approach helps build momentum and provides a sense of accomplishment, encouraging you to continue.

2. Focus on Categories, Not Rooms: Instead of tackling one room at a time, which can lead to items being shuffled from one place to another, try the “KonMari” method of decluttering by category [8]. Gather all items of a single type (e.g., all clothing from every room) and sort them in one place. This allows you to see the true quantity of items you own and make more informed decisions about what to keep.

3. Implement a Decision-Making Framework: A study on decision fatigue suggests that making too many choices can lead to poor outcomes [9]. Establish clear rules to streamline your decluttering decisions. For example, the “one-year rule” (getting rid of anything you haven’t used in a year) or Marie Kondo’s “does it spark joy?” question can help you make quicker and more consistent choices.

4. Harness the Power of Giving: The act of giving is linked to increased happiness and well-being. Donating unused items to charity or passing them on to others can provide a sense of purpose and social connection [10]. This practice transforms the release of an item from a loss into an act of kindness, which can make the process more rewarding.

5. Create a “Visual Pause”: Research from the Journal of Environmental Psychology highlights the importance of open space for mental clarity [11]. Once you have decluttered a space, intentionally create a “visual pause” by leaving certain areas clear. This creates a sense of openness and calm, preventing the space from becoming cluttered again and reinforcing the feeling of control and tranquility.

By taking these steps, you are not just tidying up; you are actively improving your mental and physical health. The benefits of a clear space extend far beyond aesthetics, offering a foundation for a calmer, more centred, and healthier life.
