Children’s growth and development is not complete, and their resistance is not as strong as that of adults, so fever is one of the common diseases in children. If it is accompanied by symptoms of nosebleeds, it is likely to be caused by the following: Upper respiratory tract infection: Because upper respiratory tract infection can lead to allergic rhinitis, and high fever can aggravate the blood pressure in the nasal cavity, causing the symptoms of nosebleeds. If the child has both fever and nosebleeds, accompanied by symptoms such as coughing and phlegm, then it can be considered an upper respiratory infection. Viral cold: If it is due to a viral cold, it is also possible to have a fever and runny nose. A cold can cause nasal congestion, accompanied by inflammation in the body, and the mucous membrane of the nasal cavity of children is relatively fragile, which can easily lead to the symptoms of nosebleeds. The surrounding environment is dry and hot: children are more sensitive to the surrounding environment, so if the surrounding environment is too hot and too dry, it will also cause the child’s body temperature to rise and have the symptoms of nosebleeds. If a child has a fever and a nosebleed, you can properly hydrate the child and drink more warm water to avoid dryness and to relieve inflammation in the body. Parents should not be too careless when taking their children, always pay attention to environmental changes and do not let them catch a cold or dry heat.
