The Earth's climate is projected to warm significantly in the 21st century, and this will affect human societies in many ways. Since sleep is a basic human need and part of everyone's life, the question of how temperature affects human sleep naturally arises. This paper examines the effect of daily mean temperature on sleep duration using nationally representative Hungarian time use surveys between 1976 and 2010. Compared to a day with an average temperature of 5-10 °C, colder temperatures do not influence sleep duration. However, as daily mean temperatures rise, sleep duration starts to strongly decline. The effect of a hot (>25 °C) day is -13.3 minutes, but if preceded by a few other hot days, the effect is even stronger, -24.7 minutes. The estimated sleep loss is especially large on weekends and public holidays, for older individuals, and men. Combining the estimated effects with temperature projections of twenty-four climate models shows that the warming climate will substantially decrease sleep duration. The projected impacts are especially large when taking into account the effects of heatwave days. This study also shows that different groups in society are likely to be affected in significantly different ways by a warming climate.
预计在 21 世纪，地球的气候将显著变暖，这将在许多方面影响人类社会。由于睡眠是人类的基本需求之一，也是每个人生活的一部分，因此，温度如何影响人类睡眠的问题自然就出现了。本文使用 1976 年至 2010 年期间具有全国代表性的匈牙利时间使用调查数据，研究了日平均温度对睡眠时间的影响。与平均温度为 5-10°C 的日子相比，较冷的温度不会影响睡眠时间。然而，随着日平均温度的升高，睡眠时间开始明显下降。炎热（>25°C）天气的影响为-13.3 分钟，但如果之前有几天炎热天气，影响甚至更强，为-24.7 分钟。这种睡眠损失在周末和公共假日、老年人以及男性中尤为明显。将估计的影响与二十四气候模型的温度预测相结合表明，气候变暖将大大减少睡眠时间。当考虑到热浪日的影响时，预计的影响尤其大。本研究还表明，不同社会群体可能会受到气候变暖的不同影响。
