After a concussion or a mild traumatic brain injury the best way to describe it is that your brain is bruised. It has an injury that it needs to recover from, and statistically speaking, most people do recover from that level of injury. When your brain is injured, much like you would rest to heal any other injured part of your body, current studies indicate that you should rest your brain as well.
You can rest your brain by reducing your screen time, reducing your need to do complicated work, and just give your brain a little bit of a rest while it recovers from that insult.
For example, for students recovering from a brain injury, they’re not going to do well in school for several weeks. It takes a while for the brain to get back to where it needs to be to be at full speed. Students recovering from a brain injury should, for example, be excused from testing, not use screens, and things like that. For adults in the workforce that can be a real challenge, but again, reduced hours, reduced responsibilities and reduced time in front of the computer will make a difference while you recuperate.
