[The significance of climate and environment protection for health under special consideration of skin barrier damages and allergic sequelae].

The skin, together with gut and respiratory tract, harbor a central epithelial barrier function in regards to the interaction of an individual with the environment. Continuing exposure to environmental influences can cause epithelial barrier damages and thus pave the way for atopy development. The latter describes the tendency for allergies, i. e. hypersensitivity of the skin, intestine, and respiratory tract towards per se unharmful environmental substances.Allergies are classified as non-communicable diseases (NCDs). According to the World Health Organization (WHO), they are presently the most demanding medical challenge. Allergies are the most frequent NCDs and are characterized by a high and multi-facetted level of suffering. An enormous socio-economic burden and the urgent need for effective prevention follows as consequence. Prevention options have by no means been sufficiently used. Within the skin barrier's key function in regards to the defense of atopic diseases are so far inadequately used prevention possibilities. They are based on ambitious environmental and climatic policy that pointedly addresses the barrier disrupting environmental factors.On the basis of this proposition, the present article assigns appropriate environmental and climatic policy measures. The two main arguments for such measures are a disburdening of the healthcare system as well as a far better life quality for the affected people. They are the legitimization towards an ambitious environmental and climatic policy. For its realization an integrated approach of (allergy) prevention and environmental research is necessary. Now, campaigning for its acceptance in politics and society is an urgent matter.
