[Spider Man] Why the hell does Spiderman always hang upside down ?

I'm no doctor but the ammounts of blood rush he can get from that is kinda dangerous right ?

Side effect of the spider DNA- that's how spiders hang from their web. A minor instinct that passed over as detritus along  with the strength and speed and so forth.

Luckily, Spiderman is superhumanly tough. He can cope  with the blood rush better then us.
