Reopening schools during the Covid pandemic significantly improved kids’ mental health, Harvard researchers said Tuesday, leading to declines in diagnoses of anxiety, depression and ADHD and a drop in related health care spending.
Analyzing the health data of more than 185,000 California schoolchildren from 24 counties, the researchers compared the students’ mental health at the pandemic’s start in March 2020, when schools closed, to when schools reopened in June 2021.
