Study calls for more attention to the sense of smell

by | Dec 2, 2025 | Health, Research

A new study from the University of East Anglia shows that a programme of odour screening, education and health interventions could improve the mental and physical health of millions of people. The sense of smell has so far been considered a neglected area in public health, although it plays a role in over 130 neurological, somatic and hereditary diseases.

The research suggests that olfactory disorders could be not just a symptom but possibly a causative factor, as they often occur early and predict future problems such as neurodegenerative diseases or a shortened life expectancy. Even before the Covid-19 pandemic, such disorders were widespread, but were underestimated and little researched. Particular emphasis is placed on the influence on nutrition, cognitive abilities and psychological resilience, which are supported by a healthy sense of smell.

The researchers therefore propose a global campaign that integrates odor screenings into preventive examinations, promotes education and raises awareness among the population. Inclusive approaches to ensure diversity and equity are of particular importance, as so far it has been mainly certain population groups that seek help. The goal is to establish the sense of smell as an essential part of health and to include it in national health agendas.

The findings, published in the journal Clinical Otolaryngology, highlight the need to pay more attention to nose and ear health worldwide.
