将20名过敏性哮喘儿童随机分为两组，每组的严重程度相匹配。一组被提供了拉链乙烯基枕头，床垫和弹簧盒，以及使卧室像医院病房一样容易保持清洁的说明;另一组没有。在1个月的研究期结束时，两组之间的哮喘症状和体征有显著的统计学差异。那些卧室无尘的人有较少的天观察到喘息，给予药物治疗，或记录到异常低的呼气流速峰值。卧室经过改造的那一组的支气管对雾化组胺的耐受性显著提高。无尘卧室减少支气管过敏，是一种实用而有效的方法，以减少哮喘儿童与房屋灰尘或屋尘螨过敏。
Twenty asthmatic children with prick tests positive for house dust or house dust mites were allocated to two groups that were matched for severity. One group was provided with zippered vinyl covers for pillows, mattresses, and box springs, and instructions for making the bedroom as easy to keep clean as a hospital ward; the other group was not. At the end of a 1-month study period, there was a marked and statistically significant difference in symptoms and signs of asthma between the two groups. Those with a dust-free bedroom had fewer days on which wheezing was observed, medication was given, or an abnormally low peak expiratory flow rate was recorded. Bronchial tolerance to aerosolized histamine significantly improved in the group whose bedrooms had been modified. A dust-free bedroom diminishes bronchial irritability and is a practical and effective method for decreasing asthma in children with house dust or house dust mite allergy.
