While physical rest is typically recommended in the first 24 to 48 hours following a concussion, rest beyond that period may negatively impact an athlete’s recovery. A Canadian study found that athletes who took more than 3 days to return to physical activity after a concussion took longer to fully return to sport than those who began gradually returning to exercise after just one day post-injury. Coaches, parents and medical practitioners should work together to help athletes safely return to activity after a concussion.
