According to the analysis of clinical data, the proportion of children with rhinorrhea in spring is much higher than other seasons. Nosebleeds are mostly sudden, often overwhelming the affected children, and if the treatment is not timely, they can bleed too much and affect their health. Why are children prone to rhinorrhea in spring? First, with the arrival of spring, children’s body yang energy also rises sharply, and blood rushes up to the nasopharynx and bleeds easily with the surge of gas. Secondly, as winter turns to spring, children who have taken off their thick clothes and heavy hats suddenly get the opportunity to go outdoors and are particularly excited, which can easily cause nasal trauma and bleeding. Third, when spring turns warm, the nasal blood vessels that have been contracted for a long time in winter expand, resulting in dryness and itchiness in the nose and other discomfort, which can cause bleeding with a little digging. Fourth, spring is the epidemic period of influenza, measles and other febrile diseases, which can be followed by nasal and sinus infections after fever, causing nasal bleeding. Since children are prone to nosebleeds in spring, they should participate in less strenuous activities and avoid nasal trauma; pay attention to a light diet and eat less fried food; prevent colds and other febrile diseases; if they have a history of nosebleeds in spring, they can take Yinhua, Chrysanthemum and Maitong to prevent them.
