In brief: Irritation anatomy

There are very large superficial vessels in the front of everyone's nose.
These vessels are easily opened by local trauma. Picking, dryness, infection, rubbing, tissues can all cause irritation and ultimately bleeding. It's always worse in the cold and dry air of winter. People with anatomic abnormalities of the nose such as septal deviation have worse bleeding problems.
