Have you ever met someone who can’t relax while there’s a dish in the sink or something out of place at home? Or maybe you’re that person?
The need to keep the house always tidy may seem like just a personality trait, but science shows there are neurological and psychological reasons behind this behavior.
1. The impact of clutter on the brain
Studies indicate that disorder in the environment can generate stress and anxiety. This happens because the human brain seeks patterns and predictability. When a space is disorganized, there is an excess of visual stimuli, which can overload the mind and make it harder to concentrate.
A study from Princeton University demonstrated that a cluttered environment impairs the brain’s ability to process information and maintain focus. This explains why some people feel mentally tired or irritated when surrounded by mess.
2. Personality and organization
The need to keep everything in its place may be linked to personality traits. People with high levels of conscientiousness – one of the Big Five personality traits – tend to be more organized and feel uncomfortable in messy environments. This trait is also associated with discipline, planning, and a sense of control over life.
Additionally, a study published in the *Personality and Social Psychology Bulletin* showed that people who describe their home as “messy” or “disorganized” have higher levels of cortisol, the stress hormone. In contrast, those who live in tidy spaces reported feeling more relaxed and in control.
3. The connection with mental well-being
Keeping the house organized can also be a form of emotional self-regulation. Many people find comfort and stress relief in organizing and cleaning their environment, as it provides an immediate sense of accomplishment and control.
Studies suggest that tidying up can activate the brain’s reward system, releasing dopamine, the neurotransmitter responsible for the sensation of pleasure. That’s why some people experience a feeling of satisfaction and well-being when they see a clean and orderly space.
4. The role of culture and upbringing
Cultural factors and upbringing also influence this behavior. Individuals who grew up in highly organized households may associate cleanliness with a sense of safety and comfort. Furthermore, social norms and expectations regarding order and hygiene can reinforce the need to keep the house always tidy.
Science shows that the need for organization isn’t just a matter of preference but rather a reflection of how the brain functions, personality traits, and emotional well-being. For some people, a tidy environment isn’t just a preference but a necessity for maintaining mental clarity and reducing stress.
And you, do you feel better in an organized space, or do you think a little mess doesn’t hurt?
