Problems related to mask use in hay fever sufferers by repeated surveys

Abstract

Purpose

Many Japanese hay fever (HF) sufferers wear a hygienic face mask to prevent pollen inhalation, but most find it very uncomfortable. The purpose of this paper is to identify the problems associated with mask wearing through repeated surveys. This information can be used in the improved design of a hygienic face mask that can be worn without discomfort by HF sufferers.

Design/methodology/approach

In 2009 (n=1,519), 2012 (n=2,994), and 2015 (n=3,213), repeated surveys of university students were conducted. HF sufferers were queried regarding symptoms, countermeasures, and problems associated with wearing a hygienic face mask. Holistic perspectives for each year were obtained by a co-occurrence analysis of the aggregated data. The triplet co-occurrence of specific problems was compared among the surveys using the χ² test. Temporary and contemporary co-occurrence relationships were also determined.

Findings

Most Japanese university students with HF wore a hygienic face mask. In each survey, the most common problems associated with mask use were related to its thermal, hygroscopic, and air-flow properties. Contemporary problems with co-occurrence relationships were “humidity,” “breathing difficulty,” and “mist over eyeglasses” for males and, “humidity,” “breathing difficulty,” and “make-up coming off” for females.

Originality/value

The results of this study will contribute to improving hygienic face mask design. The co-occurrence of contemporary problems related to mask use was identified by comparing the results obtained in each year. The thermal, hygroscopic, and air flow properties of the mask cause these problems, and the air gap between the mask and the wearer’s face influences the inherent physical properties of the mask. To measure the air gap, a suitable hydrostatic pressure-balanced experimental method was applied, and the data were demonstrated experimentally.
