Nosebleed when seeing the scene

Is nosebleed a fact when the "hot" scene is true?

In Japanese comics or cartoons, or Asian films, male characters often bleed their nose when they saw the 'hot' scene.

Sexual stimulation leading to nasal bleeding has never been recorded.

Many argue that the reason for this is that when the character is excited, the body will increase metabolism, increase body temperature and heart rate, leading to increased blood pressure, causing a fragile blood vessel in the nose to rupture. and cause bleeding.

However, according to Dr. Koichiro Kanaya in Yamaguchi, the human body is very flexible and can adapt very well, so nose bleeding is very unlikely.

On the other hand, according to the National Library of America dictionary, people with hypertension syndrome may have a nosebleed. But temporary hypertension due to sexual stimulation leading to nasal bleeding has never been recorded.

In addition, according to Yasuji Tanioka, the father of the nasal bleeding motif suggests that it is just a metaphor for climax , not just the actual physiological state.
