Evolutionary ecological theory predicts that sleep-wake state tradeoffs may be related to local environmental conditions and should therefore correlate to alterations in behavioral life history strategies. It was predicted that firefighters who slept more and reported better quality sleep on average would exhibit lower impulsivity inclinations related to slower life history trajectories. UPPS impulsivity scores and self-reported sleep averages were analyzed and indicated a negative association between sleep variables and urgency and a positive association with premeditation. Perseverance, and in some cases premeditation, however, disclosed an unpredicted marginally significant positive association between increased and emergency nighttime waking-related sleep deprivation. Sensation seeking was not associated with sleep variables, but was strongly associated with number of biological children. This research contributes to understanding the implications of human sleep across ecological and behavioral contexts and implies further research is necessary for constructing evolutionarily oriented measures of impulsivity inclination and its meaning in the context of life history strategies.
进化生态理论预测，睡眠-觉醒状态的权衡可能与当地环境条件有关，因此应该与行为生活史策略的改变相关。据预测，平均睡眠时间更长且报告睡眠质量更好的消防员，其冲动倾向会更低，这与较慢的生活史轨迹有关。对UPPS冲动性得分和自我报告的平均睡眠时间进行了分析，结果表明睡眠变量与冲动性中的紧急性呈负相关，与预谋性呈正相关。然而，坚持性，在某些情况下还有预谋性，揭示了与夜间紧急醒来相关的睡眠剥夺增加之间存在意外的微弱显著正相关。寻求刺激与睡眠变量无关，但与亲生孩子的数量密切相关。这项研究有助于理解人类睡眠在生态和行为背景下的影响，并意味着有必要进行进一步的研究，以构建基于进化的冲动倾向测量方法及其在生活史策略背景下的意义。
