Abstract

Introduction

Bedroom temperature can influence nocturnal thermoregulation and sleep. To date, limited, small experimental studies have shown that bedroom temperatures outside the recommended range of 65 and 70°F can negatively impact sleep. However, this association has not been studied in a large-scale data set. Using over 3.75 million nights of objectively measured data, we analyzed the associations between habitual bedroom temperatures and sleep.

Methods

Over 3.75 million nights of sleep and bedroom temperature data were collected using S+ by ResMed technology from 34,096 Individuals (57% male, 20-90 years, mean age 48.7 +/-14.5 years, all US residents). Multilevel regression analyses were used to analyze associations between bedroom temperature and sleep. A stricter alpha level of 0.001 was used to account for the large number of observations in the dataset.

Results

Bedroom temperature was above 70°F for 69% of nights, with the average temperature ranging between 68.8 and 76.2°F. For each 1°F increase in bedroom temperature between 60-85°F, sleep efficiency decreased by 0.06%. Likewise, higher bedroom temperatures were linked to shorter Total Sleep Time duration (-0.45 mins/°F), longer Sleep Onset Latency (+0.04 mins/°F), and longer Wake After Sleep Onset (+0.11 mins/°F), all ps<0.001.

Conclusion

Analyzing data from over 3.75 million nights, we found that many people sleep in a bedroom warmer than the optimal temperature. Further, higher bedroom temperatures - even within the recommended range for optimal sleep - are associated with poorer sleep and higher wakefulness. Bedroom thermostats and cooling options should be considered to achieve optimal sleeping temperature conditions.

1214更高的卧室温度与更差的睡眠相关：来自超过375万晚的数据

摘要

介绍

卧室温度会影响夜间的温度调节和睡眠。迄今为止，有限的小型实验研究表明，卧室温度超出建议的65至70°F的温度范围可能会对睡眠产生负面影响。但是，尚未在大规模数据集中研究这种关联。使用超过375万晚的客观测量数据，我们分析了习惯性卧室温度与睡眠之间的关联。

方法

使用ResMed技术通过S +从34,096位个人（57％的男性，20-90岁，平均年龄48.7 +/- 14.5岁，所有美国居民）中收集了超过375万晚的睡眠和卧室温度数据。多级回归分析用于分析卧室温度与睡眠之间的关联。使用更严格的0.001的alpha等级来解释数据集中的大量观察值。

结果

69％的夜晚，卧室温度高于70°F，平均温度在68.8至76.2°F之间。卧室温度在60-85°F之间每升高1°F，睡眠效率就会降低0.06％。同样，较高的卧室温度与较短的总睡眠时间长度（-0.45分钟/°F），较长的睡眠开始延迟（+0.04分钟/°F）和较长的睡眠后唤醒时间（+0.11分钟/°F）相关，所有ps <0.001。

结论

通过分析超过375万个夜晚的数据，我们发现许多人在比最佳温度更温暖的卧室里睡觉。此外，更高的卧室温度-即使在最佳睡眠的建议范围内-也会导致较差的睡眠和更高的清醒度。应该考虑使用卧室恒温器和制冷选项，以达到最佳的睡眠温度条件。
