室溫７０－７２Ｆ是符合標準的。。。您覺得冷，還跟濕度有關。。。

In the United States, an air temperature of 70 to 75°F. (21 to 24°C.) with 50 to 60% relative humidity provides a compromise between the requirements of the patients and those of the operators. In Britain, a temperature of 65 to 70°F. (18 to 21°C.) and a relative humidity of 50% is “well tolerated for many hours”. In the U.S.S.R., air-conditioning should provide in summer an air temperature of 68 to 72·5°F. (20 to 22°C.) and in winter 66 to 68°F. (19 to 20°C.) with a relative humidity of 55%.
