To obtain information on the extent and severity of asthmatic symptoms during daily life in winter, a simple questionnaire was sent to 57 asthmatic patients and a control group of 180 age-matched men and women in Göteborg. The average winter temperature there is about freezing point. About two-thirds of the asthmatic patients reported cold to be a factor causing breathing difficulties. In 37%, these symptoms made the patients avoid going out during the winter. Cold, damp air was reported by the asthmatic patients to cause more symptoms than cold, dry air. The control group reported very few respiratory symptoms.
为获取冬季日常生活中哮喘症状的程度和严重程度信息，向哥德堡的57名哮喘患者以及180名年龄匹配的男女组成的对照组发放了一份简单问卷。当地冬季平均气温约为冰点。约三分之二的哮喘患者报告称寒冷是导致呼吸困难的一个因素。37%的患者表示这些症状使他们在冬季避免外出。哮喘患者报告称，寒冷潮湿的空气比寒冷干燥的空气引发的症状更多。对照组报告的呼吸道症状极少。
