Since the 18th century, the idea of vampires' existence started to invade the human minds in many cultures. Vampirism was born first in old Romania then spread the whole world in the image of fiction work and literature.
Do you believe in vampires? You might say, "Yes, of course I do". Others could simply reject the idea, saying that it's only attached to works of fiction.
This might be difficult to say, but vampires do exist. Why?
Let's first give a little reminder of how everyone thinks vampires are like, standing on novels and movies that we watched probably thousand times so far.
We know them through fiction to be those things that are considered to be less than humans. They are feeding on blood and it seems to be very tasty for them. They use their fangs to bite their victims and drain their blood. They're vulnerable to sunlight, and they only emerge in the night. As Vampire Lestat says, "Our fingernails look like glass. And some people notice that when they don't notice anything else." They're immortal and they'll remain so forever. Yes, they're dead, but they aren't zombies (Of course, zombies' purpose isn't blood at all).
It takes a very long time to know everything about vampirism, as it took some people about five years to fully understand the history and folklore of the idea. But it would be easier to know the basic facts, on which vampirism stands.
Let's first start with the medical facts that proved the positive existence of vampires. Two medical conditions were discovered and partially related to vampirism phenomenon.
The first medical condition is "Reinfeld Syndrome". Reinfeld Syndrome produces powerful craving for blood. This case isn't fetish or supernatural, but only a voluntary blood drinking. Cures and antidotes are now discovered for that disease.
The second disease "Porphyria" could actually startle you for a few minutes. It's much more serious than the previous condition as it results in giving the person the exterior of vampires.
What does "Porphyria" mean anyway? Some enzymes in your body are needed to produce "heme", which is a very essential organic substance for you. If any of those enzymes is abnormal or has any kind of disorder, the process of heme production won't continue. So porphyrin starts to be produced in your body, as an alternative to heme. The production of Porphyrin results in:
1-Gum deformations: the disease causes the gum line to retreat or to draw back, giving the impression that a person has fangs, just like vampires.
2-Blood cravings (the only similarity with the Reinfeld Syndrome).
3-The skin along the fingernails beds, creating layers and the fingernails appear exceptionally long.
4-Sunlight allergy. They are extremely vulnerable to sunlight. They don't burn or turn to ashes, but they experience itching, redness and hives or rash on areas of skin exposed to sunlight. So, they don't go out except during the night.
Porphyria is rare and only two hundred persons were discovered to have it around the world.
What might actually interest you the most is that, not only they carve blood, but it's recommended that they get blood treatments too (In their case, drinking blood is legal).
Porphyria was discovered about two or three hundred years ago. This is where the legends of vampires began. So, vampires in the fictional context don't exist (I happened to know some real vampires, by the way).
Those were the medical conditions that might have changed your mind about vampires' existence. Nevertheless, medicine in this case only represents a very small part of vampirism facts. So, you'll read some future articles about the historical facts, vampires' types and their life style too.
Just to give you a hint for the next articles, not all vampires feed on blood.
