[MCU] Asgardians clearly don't need to breathe even in space, so why do they breath anyway?

We don't know that they don't need to breathe. We know they can last a very long time without breathing but we've seen nothing that suggests they'd survive in space for a long time. Thor is maybe the exception but A, we've no idea how long Thor was exposed and B, Thor is likely leaps and bounds more durable then most Asgardians.
