Keep in mind that each successive head bump is harder to recover from and the symptoms get worse, and if you get another concussion before the first one heals, that's bad news. If you can get through your concussion without banging your head, then great, ignore this thread. But if you've already had one or two setbacks from head bumps then you should consider head protection because the longer your PCS drags on, the higher the risk of another head bump. And if that happens then you will sink deeper into the pit that is PCS and then it will be harder to climb out than it ever was at the beginning, before the first head bump.

By the way, the Ribcap was impact tested by the British Standards Institute and it meets the rugby headgear standard, so don't write it off is useless. The others may not be as good, so that's why I added a thicker shock-absorbing material, cork, to the Crashe hat.

Bench testing helmets is quite different than practical use. The data is still being collected about the changes in concussions and sub-concussive impacts.

The bigger indicator of prolonged recovery from a concussion is not additional bumps. It is a pre-existing condition of anxiety or depression. A pre-existing anxiety and depression condition exists in something like 80% of prolonged PCS. They can use pre-existing anxiety to predict a prolonged recovery.

Wearing a helmet can enable the OCD/anxiety behaviors of such a person.

Encouraging others to become just as anxious and obsessive by using a helmet can be counter productive.
