Migrant health advantages, the ‘healthy immigrant effect’, erode over time, leading to what is known as unhealthy assimilation. Health-related behaviours are central to unhealthy assimilation, and here we focus on an understudied and central part of our daily time: sleep. Building on diverse streams of literature, we conceptualize and empirically study the sleep assimilation patterns of immigrants. With data from Germany, we demonstrate that immigrants sleep significantly more than natives upon arrival, while their sleep ‘advantage’ dissipates with years spent in the host country. We also explore the heterogeneity of the sleep assimilation process by gender, education, wages, work schedules, and job physical intensity.

不健康的睡眠同化

移民的健康优势，即“健康移民效应”，随着时间的推移而被削弱，导致所谓的不健康同化。与健康相关的行为是不健康同化的核心，在这里我们重点关注我们日常生活中一个未被充分研究的核心部分：睡眠。我们以多种文献为基础，对移民的睡眠同化模式进行概念化和实证研究。根据德国的数据，我们证明移民在抵达后的睡眠时间明显多于当地人，而他们的睡眠“优势”随着在东道国度过的时间而消失。我们还探讨了睡眠同化过程在性别、教育、工资、工作时间表和工作体力强度方面的异质性。
