The effect of ventilation on a person

Let’s start with influence on a person. The lack of oxygen, the increased content of carbon dioxide and increase humidity contribute to a decrease in performance, the appearance of headaches and exacerbation of chronic diseases. If the air is too dry, then this will negatively affect the mucous membranes. A decrease in oxygen levels negatively affects the operation of gas stoves, fireplaces and heating boilers, and excessive humidity is the cause of the occurrence of the fungus and mold.
