许多研究报告了户外环境天气与健康之间的联系。户外条件可能是个人暴露的不良指标，因为人们大部分时间都在室内。很少有研究探讨室内条件与室外环境天气的关系。从2011年5月至2012年4月，在马萨诸塞州大波士顿的16个家庭中测量的平均室内温度、表观温度、相对湿度（RH）和绝对湿度（AH）与波士顿洛根机场的测量值进行了比较。室内和室外温度之间的关系是非线性的。在室外温度较高时，室内外温度之间存在较强的相关性（Pearson相关系数，r = 0.91，斜率，β = 0.41），但在温度较低时，这种相关性较弱（r = 0.40，β = 0.04）。室外表观温度的结果相似。RH和AH呈线性关系。RH的相关性中等（r = 0.55，β = 0.39）。室内与室外的相关性最强（r = 0.96，β = 0.69）。室内和室外温度只有在室外温度较高时才有很好的相关性。室外相对湿度是室内相对湿度的不良指标，而室内空气湿度全年与室外空气湿度有很强的相关性。
Many studies report an association between outdoor ambient weather and health. Outdoor conditions may be a poor indicator of personal exposure because people spend most of their time indoors. Few studies have examined how indoor conditions relate to outdoor ambient weather. The average indoor temperature, apparent temperature, relative humidity (RH), and absolute humidity (AH) measured in 16 homes in Greater Boston, Massachusetts, from May 2011 - April 2012 was compared to measurements taken at Boston Logan airport. The relationship between indoor and outdoor temperatures is non-linear. At warmer outdoor temperatures, there is a strong correlation between indoor and outdoor temperature (Pearson correlation coefficient, r = 0.91, slope, β = 0.41), but at cooler temperatures, the association is weak (r = 0.40, β = 0.04). Results were similar for outdoor apparent temperature. The relationships were linear for RH and AH. The correlation for RH was modest (r = 0.55, β = 0.39). AH exhibited the strongest indoor-to-outdoor correlation (r = 0.96, β = 0.69). Indoor and outdoor temperatures correlate well only at warmer outdoor temperatures. Outdoor RH is a poor indicator of indoor RH, while indoor AH has a strong correlation with outdoor AH year-round.
