I’ve sat in vibrating massage chairs and I have this giant Brookstone hand held percussion massager like this that is powerful enough to beat the muktuk out of you at the highest levels. It’s pleasurable in a tactile sense while using them as the vibration is soothing but I have to wonder what’s going on inside the body with all that vibration. I’m assuming veins and arteries are pumping along while being vibrated thousands of times per minute… but how?
Why doesn’t all that vibration mess things up on microscopic scale especially inside your brain?
I’m not saying it can’t, in fact it does happen, but to figure it out why it usually doesn’t happen you ought to start with describing why you think it should.
I mean, the body is exposed to vibrations and shock waves all the time, from the natural impact when you walk to a hearing damaging concert bass. Why aren’t they scrambling your brains?
I’d guess it’s because the body isn’t a rigid construction and everything just temporarily flexes.
Only at very high levels of energy and/or extended exposure do things degrade, and most people don’t use their massagers that much, and if they start experiencing negative effects they hopefully cut back.
It’s a danger for people who work with vibrating machines a lot, and on rare occasions people who play computer games with a rumble-controller for days on end …
I have it on good authority that vibration massage to certain parts of the body actually increases blood flow in the immediate and surrounding areas, at least for a time. I shall let you Google citation pics on your own.
