What if the weather is cold and the nose is red?

It may be caused by heat and excessive internal heat. Nosebleeds are caused by rupture of nasal mucosa capillaries. Usually, people who get angry and have rhinitis are more likely to happen.

Appropriate vitamin C supplementation, drinking more water, eating more fruits, eating less spicy food, and quitting smoking and drinking can reduce the fragility of capillaries and reduce bleeding.
