The psychology of cleanliness: how the environment influences the mind

Ufficio Stampa 15 April 2025

A clean environment is not just about aesthetics: it directly impacts mental well-being and productivity. Scientific studies have shown that working or living in orderly and hygienic spaces can reduce stress, improve concentration, and foster greater efficiency. But why does this happen? And what are the implications for cleaning industry professionals?

The psychological impact of clean environments

The perception of order and cleanliness conveys a sense of control and safety. In cluttered or dirty environments, the brain can become overwhelmed by visual and sensory stimuli that increase stress levels. Conversely, clean and organized spaces promote calmness and mental clarity. Several studies compiled in the Value of Clean Report by the ISSA association demonstrate how a well-maintained work environment can reduce stress and enhance concentration, leading to increased productivity and job satisfaction.

For example, a study by Wageningen University (Netherlands) conducted on 120 employees from non-profit organizations found that a clean office positively influences employees job satisfaction.

Productivity and well-being: a direct connection

A clean environment not only enhances mental well-being but also has a tangible impact on productivity. In fact, research on Work and Employment conducted by the Berkeley Institute at the University of California, using a sample of 1,100 private companies in Belgium, revealed that a 1% increase in sick leave leads to a decrease in productivity of up to 0.66% (Source: Industrial Relations Journal 2020, 59).

Investing in cleanliness and air quality, for instance, plays a crucial role: eliminating dust and allergens helps reduce fatigue and exhaustion. Moreover, regular cleaning of workspaces minimizes the spread of germs, reduces sick absences, and improves overall morale.

A study published in the Journal of Occupational and Environmental Medicine demonstrated that avoidable healthcare requests related to hygiene decreased significantly when companies provided hand hygiene training and disinfectant products. In other words, sick leave was reduced by 20%, proving that hygiene positively affects absenteeism rates.

The role of cleaning professionals

For industry professionals, understanding the psychological importance of cleanliness is crucial. It is not just about ensuring hygienic standards, but about creating environments that promote well-being and productivity. Adopting advanced protocols and using eco-friendly and certified products can make a difference—not only for physical health but also for mental health.

In conclusion, investing in cleanliness is not just a practical choice, but a strategy for improving quality of life and business success. It's beneficial for everyone! For cleaning professionals, this means going beyond mere maintenance and embracing a holistic approach that considers mental well-being and sustainability.

These topics, along with other innovative trends in the cleaning industry, will be discussed at ISSA Pulire 2025, the international flagship event for the sector.
