Chris:作为一名听众,我发现人们对打哈欠的理解存在误区,它远比我们想象的复杂。 Noam:许多人认为打哈欠意味着无聊或不尊重,但实际上,运动员在比赛前打哈欠,以及打哈欠在各种动物中普遍存在,都表明打哈欠的原因并非单一。 Brian:最初我以为打哈欠与注意力下降和困倦有关,但随着节目的深入,我意识到这只是冰山一角。 Andrew Gallup:通过多年的研究,我发现打哈欠可能与大脑温度调节有关,它通过增加脑部血流量和吸入凉空气来降低大脑温度,这就像汽车的散热器一样。此外,打哈欠也可能在睡眠和清醒状态转换中发挥作用,并且在不同情况下具有多重功能。传染性打哈欠可能与群体警觉性和活动同步化有关,而不是简单的移情。 Noam:通过对老鼠和人类的研究,我们发现打哈欠与大脑温度变化密切相关。降低额头温度可以减少打哈欠的频率,而环境温度过高或过低也会减少打哈欠的频率。一个患有过度打哈欠症的案例也支持了这一观点。运动员在比赛前打哈欠可能是为了调节大脑温度,使大脑处于最佳状态。打哈欠在睡眠和清醒状态转换中也扮演着角色,它可能是一种多功能行为,在不同情况下发挥不同的作用。关于传染性打哈欠,越来越多的研究表明,它可能与对他人行为的模仿有关,而不是与移情能力有关。它可能有助于提高群体警觉性,并促进群体活动同步化。
