acmartin,

My best technique of minimizing head jarring is to not turn my head at the neck. Instead, I turn at my shoulders. This slows the speed of rotation. I have also learned to never shake my head No. I can get the metallic taste in my mouth from shaking my head No.

I have to limit how I bend over to pick something up from down low. For example, I have to be careful unloading the dishwasher. The bend down to pick up a dish then stand up to put the dish in the cupboard can be too much head movement.

These are all learned skills. It takes discipline to learn these habits.
