Abstract

Jet lag symptom recovery is an important challenge for pilots on flights across different time zones, but while many studies have investigated jet lag symptoms, few have examined jet lag symptom recovery in pilots, especially in empirical studies.

We used the Actigraph bracelet, a commonly used sleep monitoring tool in the Civil Aviation industry, to collect sleep quality indicators from pilots flying eastward or westward across different time zones (three flights from China to Europe and four from China to the Americas) and analyze the data to explore pilots' sleep recovery after flying across these zones.

Pilot sleep varied as an exponentially decreasing change function after crossing time zones, and after three days of rest, pilots' sleep reached base levels similar to that at three days prior to the flight.

By exploring pilot sleep recovery patterns across different number and direction of time zones, we modeled physiological processes underpinning jet lag symptom recovery and provided data supporting these patterns.

不同时区飞行后飞行员睡眠恢复模式的实证研究

时差症状的恢复对于跨时区飞行的飞行员来说是一个重要的挑战，但是尽管有许多研究调查了时差症状，但很少有研究调查飞行员的时差症状恢复，特别是在实证研究中。我们使用民航行业常用的睡眠监测工具Actigraph手环，收集向东或向西跨越不同时区飞行的飞行员的睡眠质量指标（从中国飞往欧洲的3个航班和从中国飞往美洲的4个航班），并对数据进行分析，探讨飞行员飞越这些时区后的睡眠恢复情况。飞行员的睡眠在跨越时区后呈指数递减的变化函数变化，休息三天后，飞行员的睡眠达到与飞行前三天相似的基础水平。通过探索不同时区数量和方向的飞行员睡眠恢复模式，我们模拟了支撑时差症状恢复的生理过程，并提供了支持这些模式的数据。

期刊介绍： The Journal of Air Transport Management (JATM) sets out to address, through high quality research articles and authoritative commentary, the major economic, management and policy issues facing the air transport industry today. It offers practitioners and academics an international and dynamic forum for analysis and discussion of these issues, linking research and practice and stimulating interaction between the two. The refereed papers in the journal cover all the major sectors of the industry (airlines, airports, air traffic management) as well as related areas such as tourism management and logistics. Papers are blind reviewed, normally by two referees, chosen for their specialist knowledge. The journal provides independent, original and rigorous analysis in the areas of: • Policy, regulation and law • Strategy • Operations • Marketing • Economics and finance • Sustainability
