The environment includes group environment and individual environment. Human group environmental pathogenic factors refer to a large range of outdoor air, water, soil, large areas of allergenic pollen vegetation, and large areas of airborne sources of allergenic bacteria. The individual microenvironment refers to the individual's living environment. Since people spend about 2/3 of their lives indoors, the individual microenvironment has a closer impact on eczema.
