This prevalence of atopic dermatitis among various countries explains the importance of the environmental factor in the disease count. There are many environmental factors that can contribute to the development of atopic dermatitis, which includes hygiene, bacterial exposure, contact with outdoor living animals, weather, intestinal macrobiotic, etc. The main environmental factors responsible for the development of atopic dermatitis has not yet been identified, but many environmental factors together can contribute to its development. Therefore, the environmental condition can be called as a risk factor for the development of atopic dermatitis. For example, in winter, chiller temperature can flare eczema in some people. Dry weather also leads to itching and scratching. Likewise, extremely hot weather and sweat lead to itchy skin. As the first symptom of atopic dermatitis is an itchy, inflamed skin, therefore hot and cold weather can affect the skin, making skin more prone to eczema.
