(lemmy.fmhy.ml)
A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Probably because you're holding your breath in the whole time which cuts off oxygen to your brain, which is what causes fainting
Well that ain't it. It happens within seconds. The other explainations with the nerve sound more readable.
