And what be done about bone density? I guess exercise would help but not with the bones in the head?

From [1]:

> Animal and human studies suggest that high-frequency, low-magnitude vibration therapy improves bone strength by increasing bone formation and decreasing bone resorption.

So you could apply vibration to the head bones. Not sure about any side effects.

Before you apply vibrations to your skull, note that it contains other things than bones that might be less thrilled about said vibrations.

Or more thrilled, who knows - be careful out there, and if you do something stupid, take notes and share the results for our entertainment^W learning!

Well, I apply a vibrating device to my skull every morning and evening (indirectly).

It's my electric toothbrush :)

Indeed. Wasn't there an article just a few days ago about Navy Seals (?) suffering brain injury from being too close to artillery being fired or some such? The vibrations in the skull were thought to be the culprit.

That was shockwaves that damages brain tissue as it passes through it. Dont try to use a jackhammer as bone vibrator.

I have been getting ads lately for an aerobic step with a vibrating motor built into it, for this very purpose. It might have been on Peacock, and if so it was during Tour de France footage.

It’s a small effect but real, and it’s passive from the patient’s standpoint and we always seem to find that to be a selling point. This research was, if I recall, originally done for NASA and studied sheep. Shake a Sheep for Science!

Humming?? No mention of bone density in this article, but there may be some benefits: https://theconversation.com/is-humming-healthy-mmm-heres-wha...

vibration does something, secret tip for migraines is massage wand to the face, almost as good as using it in other places

You can get a concussion pretty rapidly from vibrating your head.

Driving motorbikes?

resistance training is indeed the recommendation for non-head bones, if you’re looking for a confirmation:

Regarding the jaw bones: chewing. And keeping your teeth healthy: missing teeth can result in loss of bone density.

Bone density is definitely an adaption from resistance exercise.

I don't know any specific studies, but I would expect that the bone density improvements are in some sense systemic in that the metabolic changes that increase bone density will have spillover effects to bones not directly involved in some given movement.
