Histamine is one of five biogenic amine neurotransmitters, namely; dopamine, norepinephrine, epinephrine, serotonin and histamine. To put it simply it is the body’s first response to allergy – a reaction that triggers skin disorders.
Histamine is made throughout the bodies tissues, especially in the GI track, skin and lungs and is produced by the immune system as an inflammatory response, hence the signal the body uses like potential allergy reactions. When stressed, or worse, when our immune system is down, histamine is released that leads to allergy reactions. Although stress alone doesn’t actually cause allergies, it can make an allergic reaction such as rashes and reddening of the skin.
