Clutter and mental fatigue: The science of home organization

Scientific research and organizational expertise suggest that household clutter significantly impacts mental well-being by increasing cognitive load and visual noise. Studies from Princeton University indicate that environments with excessive visual stimuli compete for attention, which can reduce concentration and elevate cortisol levels, the hormone associated with stress.

Psychologically, clutter acts as a series of micro-stimuli that prevent the brain from fully relaxing. To mitigate this, organization expert María Fernández suggests practical methods to reduce visual noise without intensive cleaning. These include keeping dining tables clear, managing entryway clutter, avoiding leaving clothes on chairs, and hiding visible cables and chargers to improve the overall perception of order and tranquility in the home.
