“午餐后下沉”是一种常见的行为现象，尽管用词可能有误。人类睡眠倾向节律的双相模型提出了下午警觉性下降的另一种解释。对来自三个年龄组(10-12岁，16-17岁，62-74岁)的16名志愿者进行了多次睡眠潜伏期测试(MSLT)，每隔2小时测量一次睡眠倾向。基线得分没有显示出显著的一天中的时间效应，尽管在年龄最大的一组中存在下午下降的趋势。在固定的例行公事中，两个老年组发现了显著的一天中的时间效应，而青春期前组则没有。结果表明，午间睡眠倾向的增加与食物摄入量无关，但可能与发育或成熟过程有关。
The "post-lunch dip" is a common behavioral phenomenon, though perhaps a misnomer. Biphasic models of the human sleep tendency rhythm suggest an alternative explanation for the afternoon decline in alertness. Sleep tendency was measured with the Multiple Sleep Latency Test (MSLT) at 2-hour intervals in 16 volunteers from three age groups (ages 10-12, ages 16-17, ages 62-74 years) during a constant routine in which small meals were given each hour. Baseline scores showed no significant Time of Day effect, although a trend for an afternoon dip was present in the eldest group. During the constant routine, a significant Time of Day effect was found for the two older groups and not for the prepubertal group. The results indicate a midday increase in sleep tendency that is unrelated to food intake but that may be related to developmental or maturational processes.
