We're all sleeping worse due to COVID-19, study shows

Spending more time at home due to coronavirus lockdowns has given people more time to sleep -- but that sleep has not been restful, according to a new study published in the journal Current Biology on Wednesday. 

The study from the University of Basel in Switzerland examined sleep patterns in 435 people during the strictest phase of lockdown in Austria, Germany and Switzerland, from mid-March through April. Working from home let people adjust their sleep schedules to match their biological rhythms -- often staying up later and sleeping later, and keeping sleep more consistent between weekdays and weekends, reducing what's known as "social jetlag." The new schedules also added an average of 15 minutes of sleep on per night, the study found. Despite this, sleep quality declined, participants reported. 

"Usually, we would expect a decrease in social jetlag to be associated with reports of improved sleep quality," cognitive neuroscientist and study co-author Christine Blume said in a press release. "However, in our sample, overall sleep quality decreased. We think that the self-perceived burden, which substantially increased during this unprecedented COVID-19 lockdown, may have outweighed the otherwise beneficial effects of a reduced social jetlag."

It's not surprising that the stress of the pandemic worsened sleep quality, Blume said in the release. But from a sleep health perspective, the increase in sleep duration and regularity is a positive change, she added.
