Hi. While carrying a box, I walked into a door. There was no impact to the head but I was walking pretty fast and felt my head jerk painfully hard. Need to know what is the max force that could have been to my brain.

Also would like any info about the durability of brain compared to something like skin. with skin, you can slap a table and think nothing of it and not even bruise. what kind of damage would that do to brain from in your head?

About 30g max from my calculations:

Body jolt

That particular incident messed me up but it all depends on head movement. If your head moved it's actually better, that incident was very unlucky for me because I was leaning forward and looking down with nowhere for the head to go.

Also I'm very jolt sensitive these days

Normal concussions happen around 100g - quite a lot really. You basically have to take a hard tackle or have direct head contact on an unforgiving surface at walking speed.

Cushioning will make a big difference, which is why you can let your head fall into your pillow etc.

You need to subject the brain to 60 Gs or more to cause a concussion. A sudden stop into a door may be 2 Gs.

People need to stop and think. Act intelligent when you think. If you could bump into things before, you can still bump into things.

Personally, I will not longer spend my time telling people their little bumps are not brain damage. It is just foolish anxiety.

If you took a bowling ball and dropped it on your foot from about a foot, that is approaching a concussion level impact. OUCH. That can break your foot bones. Imagine it dropping on your head.

None of these little bumps come even close. If they were damaging, the human race would have killed itself off millennium ago.

Get over this Concussion Anxiety Disorder. There are plenty of us who have real damage from severe forces. Complaining about bumping into a door is just nonsense.
