When is it safe to go back to sports?

Every concussion is different, so there’s no standard timeline for resuming pre-concussion activities. Doctors generally say that physical activity should begin slowly, first with walking and then slow jogging. If no symptoms — like dizziness or headache — recur, the person can resume more active sports. After an initial rest period, doctors say activity is probably good for the brain. But a subsequent concussion can be more dangerous and require a longer recovery.
