In anime and manga, when characters are excited – often sexually excited – blood flows or flows. But does this depend on medical science? Nope!
The notion that excitement or arousal induce bloody noses (hanaji or "") is not just part of the manga or anime iconography. It has also become an old tale of wives. In Japan at least.
Japanese site Netallica Ask an otolaryngologist if the doctor's ears, nose and throat could confirm if sexual arousal causes nosebleeds.
"Bloody noses," says Dr. Kouichirou Kanaya, "are probably used to show how dramatically the change induced by sexual arousal is excessively important."
This is a highlight, and in manga, this often seems to be a code for ejaculation.
The trope is very Japanese, appearing in the popular culture of the country and with various shades of anime and manga. This is not a new trope and has been around for years.
Manga artist Yasuji Tanioka is thought to be the first to introduce the motif into his early 1970s manga. Yasuji no Mettameta Gaki Dou Kouza. Other manga artists liked the expression and began to reproduce it in their own work.
According to Dr. Kanaya, "the notion that sexual arousal increases heart rate and blood pressure is a well-documented fact; However, in reality, sexual arousal and bloody noses have no direct link. "
Bleeding in the front of the nasal septum often causes nosebleeds. In the case of children, picking could cause bloody noses. There are plenty of other reasons that can cause bloody bleeding from dry air to cocaine use, hemophilia allergies, and so on. (The list of the Mayo Clinic is much more detailed).
Nasal bleeds caused by sexual arousal do not seem to be supported by medical science, they have become a shortcut for stimulation. If they have spent so many decades, do not expect the trope to stop so early.
