I want to add a quick question to this thread.

While sneezing, the head usually moves forward very quickly. This resultd often in an unpleasant pressure feeling in the head afterwards.

Because of that I formed the habit to fix my head with my hands, so that it can't move forward. Indeed it does move forward at least a bit, a complete prevention is just not possible. I wonder if the fixing with the hands even highers the forces on the head, because they stop the head earlier than in it's natural movement while sneezing.

However I have to admit that, from my experience, these method prevents the pressure feeling afterwards.
