The possibility of nosebleeds exists when air conditioning is blown too much.
Air conditioning process, through the role of condensation and evaporation, will reduce the moisture content of indoor air, resulting in the phenomenon of increasingly low humidity in the confined space. The glands contained in the nasal mucosa will control the speed and composition of mucus secretion according to the environmental humidity and physiological needs, through the neurohumoral regulation mechanism.
When the environmental humidity continues to fall, the air gradually dry, the mucus secretion of the nasal mucosa surface increases to replace the loss of water, to protect the normal physiological function of the nasal cavity. But with the mucus secretion rate can not make up for the air conditioning dehumidification effect of the consumption, will lead to the nasal mucosa exposed to dry air, the mucosal surface may be cracked due to drying and bleeding, manifested as nasal bleeding symptoms.
When in a closed air-conditioning environment for a long time, should be appropriate in the environment, the nasal cavity and the whole body appropriate supplementation of water, in order to prevent the occurrence of nosebleeds. If the bleeding cannot be stopped by itself, simple compression treatment is required to seek medical treatment and standardized diagnosis and treatment.
