In two new studies, researchers found that stay-at-home orders and “lockdowns” related to the COVID-19 pandemic have had a major impact on the daily lives of people around the world and that includes the way that people sleep.
Both studies show that relaxed school and work schedules and more time spent at home have led people to sleep more on average with less “social jetlag” as indicated by a reduced shift in sleep timing and duration on workdays versus free days.
But, at the same time, one of the studies also finds that the pandemic has taken a toll when it comes to self-reported sleep quality.
The research was conducted by scientists at the University of Basel and elsewhere.
In their study, the team explored the effects of the strictest phase of the COVID-19 lockdown on the relationship between social and biological rhythms as well as sleep during a six-week period from mid-March until the end of April 2020 in Austria, Germany, and Switzerland.
Their data showed that the lockdown reduced the mismatch between social and biological sleep-wake timing as people began working from home more and sleeping more regular hours from day to day.
People also slept about 15 minutes longer each night. However, the self-reported data indicated a perception that sleep quality had declined.
In the other study, researchers asked similar questions by comparing sleep prior to and during Stay-at-Home orders in 139 university students as they shifted from taking their classes in-person to taking them remotely.
As the team reports, nightly sleep duration increased by about 30 minutes during weekdays and 24 minutes on weekends. The timing of sleep also became more regular from day to day, and there was less social jetlag.
Students stayed up about 50 minutes later while staying home during weekdays and about 25 minutes later on weekends.
Students that tended to sleep less before the effects of COVID-19 took hold showed the greatest increase in the amount of sleep after they stopped going to in-person classes.
After the Stay-at-Home orders went into effect, 92% of students got the recommended 7 hours or more of sleep per night, up from 84% before.
The team says insufficient sleep duration, irregular, and late sleep timing, and social jetlag are common in modern society.
Such poor sleep health behaviors contribute to and worsen major health and safety problems, including heart disease and stroke, weight gain and obesity, diabetes, mood disorders such as depression and anxiety, substance abuse, and impaired immune health, as well as morning sleepiness, cognitive impairment, reduced work productivity, poor school performance and risk of accident/drowsy driving crashes.
The findings show that a better understanding of which factors during Stay-at-Home orders contributed to changed sleep health behaviors may help to develop sleep health intervention strategies.
One author of the study is a sleep researcher and cognitive neuroscientist Christine Blume.
The study is published in the journal Current Biology.
