China’s students are back at school. But students in other countries still face many more months of school closures and other social restrictions. In the US alone, at least ۳۲٫۵ million public school students have had their education interrupted due to the pandemic.

To help support their children, and protect against developing mental health issues, Yeary said parents should encourage exercise and good sleep hygiene. More than anything, she said, children need to feel secure.

“Researchers have found children do best when they are experiencing stress when we help them feel safe,” Yeay said. “As much as possible, keep a routine. It doesn’t have to be rigid, but when young children know what comes next in their day they show less anxiety or problematic behavior.”
