In a questionnaire survey of a random sample of 1000 children aged 7 years, a significantly greater proportion of those living in homes reported as damp were affected by wheeze (22% v 11%), day cough, night cough, and chesty colds. Simultaneous estimation of relative humidity in the bedrooms of 778 children and continuous 7 day recordings of ambient temperature and humidity in a stratified sample of 317 bedrooms showed no association with the same respiratory symptoms. No correlation was found between bedroom conditions and baseline ventilatory function or exercise induced reduction in FEV1. These results run counter to the widely held belief that indoor temperature and humidity are important determinants of respiratory ill health, although they do not directly exclude effects due to mites or moulds, whose survival is determined by the humidity of their respective microenvironments.
在一项对1000名7岁儿童的随机样本进行的问卷调查中，居住在被报告为潮湿房屋中的儿童，患喘息（22%对11%）、日间咳嗽、夜间咳嗽和胸闷感冒的比例明显更高。对778名儿童卧室的相对湿度进行同步估算，并对317间卧室的分层样本进行连续7天的环境温度和湿度记录，结果显示与相同的呼吸道症状无关。未发现卧室环境与基线通气功能或运动诱发的第一秒用力呼气量（FEV1）降低之间存在相关性。这些结果与广泛持有的观点相悖，即室内温度和湿度是呼吸道健康不良的重要决定因素，尽管它们并未直接排除螨虫或霉菌造成的影响，而螨虫和霉菌的生存取决于各自微环境的湿度。
