<p>I wouldn’t know since I’ve never tried it before and never will. But I see conflicting scientific studies, so I’m just curious about whether or not it does.</p>
<p>When you think about it, such rapid movement would overcome the absorbing abilities of cerebrospinal fluid and do some sort of structural damage over time-- It would definitely kill brain cells by tearing axons.</p>
<p>And yet musicians who do it don’t see their abilities affected negatively.</p>
<p>It probably does insignificantly. There are so many things that humans do that could exert the same forces on the brain. There’s no trauma and it isn’t particularly jarring.</p>
<p>It depends on the style of headbanging. I personally headbang like I’m nodding yes. Many people practically throw all their force onto their head and shove it up and down. That could most likely just give those people a sore neck.</p>

Yeah, that’s probably part of it. Also interesting to note is that while jogging or jumping on a trampoline, the S-shaped spine of the body will absorb it, leaving little jarring to go to the head.</p>
