Constantly checking for news about the Covid-19 pandemic takes a toll on mental health, a Singapore study of more than 1,100 participants has shown. People who spent more time checking the news - for example, more than two hours a day - at the peak of the pandemic in Singapore were at a higher risk of feeling depressed, anxious and stressed. The study, conducted by Yale-NUS College assistant professor of social sciences (psychology) Jean Liu, was published in the Journal of Medical Internet Research in September. It is the first of five Covid-19-related projects she has been working on since March, to be published in an international academic journal.
