The symptoms of nosebleeds when washing the face are often caused by the high temperature of the water used to wash the face, which leads to excessive dilation of the mucosal vessels in the nasal cavity, thus triggering nosebleeds. Some patients may have a certain degree of excessive dryness of the nasal mucosa, or have inflammatory infectious and allergic diseases of the nasal cavity or sinuses, which can easily lead to nasal bleeding due to the dilatation of the nasal mucosal vessels. In addition, some patients may have a deviated nasal septum or bleeding-prone growths such as hemangiomas and bleeding polyps in the nasal cavity. Nosebleeds may also occur due to irritation of the nose when washing the face, which may cause nosebleeds. If nosebleeds occur repeatedly, a detailed examination of the nose is required.
