Abstract

ABSTRACT The aim of the study was to evaluate the sleep, sunlight exposure, chronotype, mood and physical activity of college students in two consecutive years during the COVID-19 pandemic (Brazilian Clinical Trials Registry: RBR-4m5j4s). The students (n = 318) answered questionnaires in two moments (2020 - time 1 and 2021 – time 2). The data showed that there was less sunlight exposure and a chronotype with more morning tendencies in the time 2, but with no difference in sleep quality. College students walked more and sat less on weekends, but with no difference in the physical activity level. Physical activity and morning chronotype were associated with lower psychological impact. Therefore, college students, despite being less exposed to sunlight and having greater morning trends in 2021, maintained psychological symptoms, sleep quality and physical activity in the first two years of the pandemic. However, students who practiced physical activity and were mornings suffered less psychological impact.

在2019冠状病毒病大流行的第二年，大学生变得更加早起:对睡眠、情绪、阳光照射和身体活动的影响

本研究旨在评估2019冠状病毒病大流行期间连续两年大学生的睡眠、阳光照射、睡眠类型、情绪和身体活动(巴西临床试验注册:RBR-4m5j4s)。318名学生(n = 318)在两个时间段(2020年时间1和2021年时间2)回答了问卷。数据显示，在时间2中，阳光照射较少，睡眠类型更倾向于早晨，但睡眠质量没有差异。大学生在周末走路更多，坐得更少，但在身体活动水平上没有差异。体力活动和早晨的时间类型与较低的心理影响有关。因此，尽管2021年大学生暴露在阳光下的时间更少，早起的趋势更多，但在大流行的头两年，他们的心理症状、睡眠质量和身体活动都保持不变。然而，锻炼身体和早起的学生受到的心理影响较小。

期刊介绍： The principal aim of Biological Rhythm Research is to cover any aspect of research into the broad topic of biological rhythms. The area covered can range from studies at the genetic or molecular level to those of behavioural or clinical topics. It can also include ultradian, circadian, infradian or annual rhythms. In this way, the Editorial Board tries to stimulate interdisciplinary rhythm research. Such an aim reflects not only the similarity of the methods used in different fields of chronobiology, but also the fact that many influences that exert controlling or masking effects are common. Amongst the controlling factors, attention is paid to the effects of climate change on living organisms. So, papers dealing with biometeorological aspects can also be submitted. The Journal publishes original scientific research papers, review papers, short notes on research in progress, book reviews and summaries of activities, symposia and congresses of national and international organizations dealing with rhythmic phenomena.
