在人类中，睡眠调节与社交时间紧密相关，社交时间将当地时间分配给学校、工作或就餐等活动。通过量化工作日和非工作日的睡眠时间之间的差异，从流行病学的角度研究了这些社交时间，即集体社交时间压力对睡眠的影响。这种差异被称为社会时差(SJL)。新冠肺炎强制的社交限制(SR)通过影响世界各地的社交时代，构成了一种全球干预。我们发起了一项全球时间日冕调查(GCCS)，查询SR前和SR期间的睡眠-醒来时间(preSR和inSR)。来自40个国家的11431名成年人在2020年4月4日至5月6日期间进行了调查。最终样本包括7517名受访者(68.2%的女性)，他们在SR下的天数为32.7 ± 9.1(平均 ± SD)。SR导致了强劲的变化：工作日和自由日的中间睡眠时间分别推迟了50和22分钟；工作日的睡眠时间增加了26分钟，但自由天的睡眠时间缩短了9分钟；SJL减少了 ~ 30分钟。在SR中的工作日，大多数人的睡眠-觉醒时间接近SR之前的无睡眠时间。睡眠时间和SJL的变化与不使用闹钟有关，在年轻人中更明显。数据表明，在大流行前的社会时间压力下，存在着巨大的睡眠不足，为不同年龄段的实际睡眠需求提供了洞察力，并表明可耐受的SJL约为20分钟。放松的社交时间压力有助于增加睡眠，缩小SJL，减少闹钟的使用。
In humans, sleep regulation is tightly linked to social times that assign local time to events, such as school, work, or meals. The impact of these social times, collectively—social time pressure, on sleep has been studied epidemiologically via quantification of the discrepancy between sleep times on workdays and those on work-free days. This discrepancy is known as the social jetlag (SJL). COVID-19-mandated social restrictions (SR) constituted a global intervention by affecting social times worldwide. We launched a Global Chrono Corona Survey (GCCS) that queried sleep–wake times before and during SR (preSR and inSR). 11,431 adults from 40 countries responded between April 4 and May 6, 2020. The final sample consisted of 7517 respondents (68.2% females), who had been 32.7 ± 9.1 (mean ± sd) days under SR. SR led to robust changes: mid-sleep time on workdays and free days was delayed by 50 and 22 min, respectively; sleep duration increased on workdays by 26 min but shortened by 9 min on free days; SJL decreased by ~ 30 min. On workdays inSR, sleep–wake times in most people approached those of their preSR free days. Changes in sleep duration and SJL correlated with inSR-use of alarm clocks and were larger in young adults. The data indicate a massive sleep deficit under pre-pandemic social time pressure, provide insights to the actual sleep need of different age-groups and suggest that tolerable SJL is about 20 min. Relaxed social time pressure promotes more sleep, smaller SJL and reduced use of alarm clocks.
