Many individuals complain of disturbed sleep during the wintertime when their air conditioner (AC) is off. Therefore, we conducted this study to objectively assess the impact of AC sound on sleep latency, sleep duration, and sleep efficiency.
An experimental study was conducted on 48 healthy young adults, in their homes, to assess the effect of a standardized AC white noise, on sleep latency, duration, and efficiency, while simultaneously monitoring light intensity and room temperature. The study was conducted during the winter months. Sleep quality was objectively assessed using sleep actigraphy. Participants were monitored for two nights, during which two different, randomized sets of conditions were used: During one of the nights, the adults were exposed to 43 dB AC white noise; during the other night, adults were not exposed to the AC white noise.
Actigraphy results showed that the mean sleep duration during the AC sound nights (ASNs) was 466.8 ± 60.8 min, compared to 478.8 ± 55.4 min during the non-AC sound nights (NASNs) ( = 0.6). Sleep-onset latency was 10.8 ± 15.2 min and 15.1 ± 18.2 min during the ASNs and the NASNs, respectively ( = 0.8). Moreover, there was no difference in sleep efficiency, 81% ± 7.8% vs. 78.8% ± 15.4% in the ASNs and NASNs, respectively ( = 0.9).
AC sound had no significant positive effect on sleep duration, latency, and efficiency.
许多人抱怨在冬季空调关闭时睡眠受到干扰。因此，我们开展了这项研究，以客观评估空调声音对入睡潜伏期、睡眠时间和睡眠效率的影响。
对48名健康的年轻成年人在其家中进行了一项实验研究，以评估标准化的空调白噪声对入睡潜伏期、睡眠时间和睡眠效率的影响，同时监测光照强度和室温。该研究在冬季进行。使用睡眠活动记录仪客观评估睡眠质量。对参与者进行了两晚的监测，在此期间使用了两组不同的随机条件：其中一晚，成年人暴露于43分贝的空调白噪声中；另一晚，成年人未暴露于空调白噪声中。
活动记录仪结果显示，空调声音夜间（ASNs）的平均睡眠时间为466.8±60.8分钟，而非空调声音夜间（NASNs）为478.8±55.4分钟（P = 0.6）。入睡潜伏期在ASNs期间为10.8±15.2分钟，在NASNs期间为15.1±18.2分钟（P = 0.8）。此外，睡眠效率没有差异，ASNs和NASNs分别为81%±7.8%和78.8%±15.4%（P = 0.9）。
空调声音对睡眠时间、潜伏期和效率没有显著的积极影响。
