The study conducted by the University of Zurich (Switzerland) points out that teenagers slept 75 minutes more during the beginning of the covid-19 pandemic, due to the rise of virtual classes. According to the article, this better sleep yielded better quality of life, and the consumption of alcohol and caffeine decreased during this period.
To reach this conclusion, the group of scientists conducted an online survey of more than 3,600 high school students in the Zurich region. On the form, there were questions about sleep habits and other behavioral characteristics. The results were compared with a survey conducted in 2017 with more than 5,300 students.
