University students represent a population group exposed to high academic workloads, irregular sleep patterns, psychosocial pressure and environmental disturbances, all of which influence cognitive functioning and mental stability. Contemporary research demonstrates that sleep hygiene, physical activity, environmental ergonomics, psychosocial support and behavioral hygiene collectively determine cognitive efficiency. In Uzbekistan, national sanitary rules and norms—including the SanQvaM system, hygienic standards for indoor microclimate, lighting, noise, daily routines and educational environments—are critically important for protecting mental performance and preventing cognitive decline among young adults.

This extended scientific article integrates global research with Uzbekistan’s hygienic norms to construct a multidimensional cognitive-hygiene assessment model for university students. Evidence shows that insufficient sleep, prolonged screen exposure, academic overload, inadequate hydration, poor nutrition and non-compliance with sanitary requirements (microclimate, ventilation, lighting, seating ergonomics) significantly reduce attention, memory consolidation, executive functioning and emotional resilience. The paper emphasizes the necessity of incorporating national hygienic regulations into student environments and outlines detailed methodological recommendations for future studies.
