For some performance variables, and some individuals, there is a dip in performance during the midafternoon hours (referred to as the post-lunch dip) that is linked to an increase in sleep propensity at that time of day. The post-lunch dip is a real phenomenon that can occur even when the individual has had no lunch and is unaware of the time of day. This dip has its roots in human biology, and may be linked to the size of the 12-hour harmonic in the circadian system. It is certainly exacerbated by a high-carbohydrate lunch, and may be more likely to occur in extreme morning-type individuals.
对于某些绩效变量以及某些个体而言，下午中段时间会出现绩效下滑（称为午餐后低谷），这与该时段睡眠倾向增加有关。即使个体没有吃午餐且不知道当时的时间，午餐后低谷也是一种真实存在的现象。这种低谷源于人类生物学，可能与昼夜节律系统中12小时谐波的大小有关。高碳水化合物午餐肯定会加剧这种情况，并且在极端晨型个体中更有可能发生。
