The immune system is our body's natural defense mechanism against illnesses and their germs. Generally, our body’s defense successfully fights colds and other infections that we develop in everyday life. Therefore, most viruses, bacteria, fungi and other germs cannot trigger an illness and are largely repelled unnoticed. If the immune system has been weakened due to stress, unbalanced lifestyle, other illnesses that have just been overcome and/or an insufficient supply with certain biofactors – we are more prone to have infections. The longer the immune system needs to eliminate germs, the more defense reactions occur, for example coughing, cold symptoms, and even fever are such defense reactions that the body uses to banish viruses and bacteria. To prevent all this – especially during the flu season: Actively support your immune system and health!
