The most suitable living environment for emphysema is a place with less dust and pollen, while ensuring a certain level of humidity and paying attention to the right temperature. Emphysema is mainly caused by prolonged inhalation of dust, exposure to polluted environments, smoking, etc. Therefore, it is important to make sure that the indoor environment is clean to avoid the respiratory tract from being re-infected. The room should be ventilated regularly every day to expel the dirty air and reduce the density of pathogenic microorganisms in the air. Emphysema patients can also be aggravated by colds, so it is important to ensure that the indoor temperature is not too cold or too hot. When the air is too dry, the mucous membrane of the respiratory tract will become dry, which is not conducive to coughing up phlegm, so the humidity in the room should be increased. In addition to improving the living environment, emphysema patients should consult a doctor and take medication if symptoms of dyspnea and coughing occur.
