From a cosmetic point of view, almost everybody exclusively focuses on the skin to counter aging, when they should be at least as concerned with bone density.
Lots of people have perfect skin, but they still look old. Why? Bone morphology. The zygomatic bone erodes, and the orbital gaps widen. The mandible degrades and pivots down and backwards (jaw rotation). Issues like resorption are currently very challenging. Skin is comparatively much easier. Also (and besides well-known interventions like collagen, retinoids, HA, and dermarolling), Epidermal and Keratinocyte Growth Factors are already very cheap, and showing much promise.
For anyone else wondering: your body is continually pulling calcium from your bones for metabolic processes. Usually it gets replaced when you consume something with calcium in it.
It makes sense to have somewhere to store extra nutrients so you can keep functioning for a long time between taking in those specific nutrients again.
Your body does this with a lot of your organs. Fat is obviously calorie storage, but muscles can also be resorbed for energy under starvation conditions (or just when they're under used). Your kidneys can resorb water from stored urine, and your intestines pull most water out of what you consume. Most neurotransmitters and hormones get recycled at various rates and turned into new molecules.
I'm sure there's more, but that's all I know of offhand.
> 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.
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.
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!
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.
