Allergies
When foreign substances (allergens) enter your body, it will react with defensive measures that can be recognized by their typical signs (swelling, reddening, inflammation of the skin or mucous membrane, sniffling).
The immune system will even fight against harmless foreign substances – and that is the basis of an allergic reaction.
Here the immune reaction clearly overshoots the target and is directed against pollen, dust mites, mold, food, insecticides and animal hair.
If it is not possible to ban the substance from your environment, the effects continue to appear again with every contact, and they can worsen and expand. Many times, illnesses such as neurodermatitis, chronic eczema, hives / urticaria, respiratory problems, diarrhea and circulatory collapse can be the effect.
