The impact of high temperatures on performance in work-related activities
研究高温如何影响职业网球运动员在重大赛事中的表现，发现气温升高会显著降低表现，但比赛重要性高或持续高温时影响较小。
High temperatures can have a negative effect on work-related activities because workers may experience difficulties concentrating or have to reduce effort in order to cope with heat. We investigate how temperature affects performance of professional tennis players in outdoor singles matches in big tournaments. We find that performance significantly decreases with ambient temperature. This result is robust to including wind speed and air pollution in the analysis. There are no differences between men and women. However, there is some heterogeneity in the magnitude of the temperature effect in other dimensions. In particular, we find that the temperature effect is smaller when there is more at stake. Our findings also suggest that the negative temperature effect is smaller if the heat lasts, i.e. there is some adaptation to high temperatures.
