Why does my nose turn red when the weather is cold?

It may be caused by dryness and internal heat. Nose bleeding is caused by the rupture of capillaries in the nasal mucosa. Usually people who suffer from internal heat or rhinitis are more likely to develop it.

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