New United States government guidelines recommend that after sustaining a concussion, children should refrain from physical and mental activities for the first three days, including school and sports, and then gradually resume their normal routine. Researchers Dr. Matthew Breiding notes, “Some children and teens think concussions aren’t serious or worry that if they report a concussion they will lose their position on the team or look weak. Remind them that it’s better to miss one game than the whole season.” JAMA Pediatrics, September 2018
