How Long Does A Vampire Need To Drink Blood? Science Has The Answer

Physics students from the University of Leicester have calculated the amount of time vampires like Dracula would need to obtain an ideal amount of human blood.

Let's say you're a vampire who really needs to grab a quick meal and run before those pesky hunters catch up to you. How much time do you need? We now have the answer, thanks to physics students from the University of Leicester. (Whether they were mesmerized into collecting the information is something we'll never truly know.)

Of course, since this is real science - even it's about vampires - some parameters need to be set. First and foremost, the study assumed vampires don't have to kill anyone to satisfy their hunger. Which is fair, because presumably vampires have to watch their calories like anyone else. Next it decided not to account for gravity, assuming the blood pressure would be strong enough to push it from the wound. That also means vampires don't actually have to suck the blood, so that measurement is out. Finally, it assumed the blood would come out of two small holes in the neck, and that each artery was of equal size.

With this information in mind, the researchers calculated how long a vampire could obtain the maximum amount of blood before encountering diminishing returns. And there's actually a good benchmark for that - once a human loses 15 percent of their blood, their heart rate changes, meaning the amount of blood a vampire could consume is reduced. With all the information above, that 15 percent mark would be reached in 6.4 minutes. After that, your vampire is just being greedy.

Now obviously that can't account for any supernatural variables of specific vampire mythologies, let alone some of the more ridiculous multi-toothed vampire designs we've seen. But overall, it's a fairly sound reasoning for any horror writers who want a realistic timeframe before their vampires need to move on.

Isn't the question irrelevant because blood doesn't provide any appreciable caloric value and Vampires apparently don't need it anyway, being undead and powered by pure magic(or whatever we're calling these days)?

Conservation of Energy is something that doesn't exist when horror monsters are concerned, and often conservation of mass as well. Thus, MAGIC!

So... about 7 minutes? I don't know... That would assume the average vampire isn't stealthy as fuck or the average victim is as dumb as horror movie stereotype...

Other than that, we're gonna need more blood pouches...

Well, consider that in some takes on the genre, being bitten by a vampire sends you in a kind of trance or ecstatic state. It's dramatically evoked in Coppola's Dracula with Westenra and Murray moaning like nobody's business; but Vampire: The Masquerade posits that the "Embrace" feels so awesome on the receiving end of things that you just go limp. Bam, full-body orgasm, right then and there. You're too busy having the warm fuzzies and drooling to even consider putting up a fight.

Considering, there's some takes on the myth where having a limp and quiet mortal in your arms for six to seven minutes isn't a complete stretch.

Unless you're going for the more modern approach, that is, in which vampire bites are synonymous with intercourse on a one-to-one basis. In that case, sneaking a quick one in seems fairly difficult...

Also - aww, no love for my favorite vampire-related scene!

I love, love, love, absolutely freaking adore Shadow of the Vampire.

mmmmmhmmmm nope

I just like to say that the Gary Oldman Dracula was a great movie. And perhaps the last good movie done by Francis Ford Coppola.

The one thing I love about that movie above all was the theme song:

Agreed about the movie being awesome. And damn, that song was nightmare fuel, when I saw the movie as a kid.

The amount of typos in this article is annoying.
