We all know that vampires don’t need to breathe to live, yet in every movie and TV show I’ve ever seen they’re breathing. Sometimes even heavily. Which begs the question, why? I mean, I know that they are played by humans and it’d be irrational to force someone to hold their breath the entire scene – but still.
Is it a muscle memory thing?
That could make sense, like when you’re used to taking the same route to work everyday so you accidentally make a wrong turn when headed somewhere different. And breathing is something that you do from day 1 second 1 – so I could see how you would do that habitually even if it wasn’t necessary.
Is it to blend in or even feel human?
It’s possible. I mean, if someone was not breathing I’d hope that I’d be savvy enough to notice. Although most vampires don’t have souls, so they would shudder at the thought of feeling human. But perhaps they would force some air in and out to blend amongst prey.
This is the most likely, have you ever tried to talk with no air in your lungs – it’s pretty much impossible. So unless they want to run around mute, they’d have to breathe in order to speak.
Although since their hearts don’t beat it’s not that farfetched of an idea to think that their lungs wouldn’t be able to expand. But if they do expand, they probably just push the air right back out without taking any of the nutrients that our human bodies would process. But then I ask, why the seemingly random bodily functions? Their lungs can apparently expand, but their hearts don’t beat. They sleep, but I’ve never heard of a vampire going to the bathroom. And if they eat food, what then? Can their dead bodies digest anything besides blood? And since their hearts don’t beat what makes the blood flow through their veins? Does the intake of new blood move around the old blood or does it just sit stagnant in their bodies? However they start to get weak if they don’t drink, which implies that somehow their bodies feed off the blood for energy. Or perhaps blood is like water, and they start to crumble if they get thirsty because of dehydration.
And if you start comparing classic to modern vampires, well that gets even more complicated ….
