Nosebleeds at night in summer are related to environmental factors, rhinitis and deviated septum.
1. environmental factors: may be due to the summer environment is relatively hot, often close the windows and doors to open the air conditioning, indoor air is too dry, easy to lead to the nasal mucosa dry, capillary blood vessel rupture and cause nosebleeds.
2. Rhinitis: it may be due to inflammation in the nasal cavity, which leads to rupture of blood vessels under the stimulation of inflammation and causes nosebleeds.
3. deviated nasal septum: if you have deviated nasal septum, the nasal septum is curved to one side or both sides, then the mucous membrane of the nasal cavity in the protruding part is very easy to break and bleed, which causes nosebleeds at night.
Blood system diseases such as leukemia and aplastic anemia can also cause nosebleeds in babies, so it is recommended to find out the cause of the disease in a timely manner, so as to avoid delaying the disease and causing other damages.
