Just what Exactly are Histamines?
 Histamines are the neurotransmitter globules that cause allergic reactions. When human mast cells, which control the body's allergic reactions, rupture they release free histamines into the bloodstream. These cause allergy symptoms to erupt like a runny nose, watery eyes, redness and others. The symptoms are a result of histamines attempting to fend off foreign invaders. This is why a medicine that is marketed to reduce these side effects is called an "anti-histamine." However, most allergy medications simply mask the symptoms of what is still happening in the body.
Histamines perform a variety of functions once they are released into the tissues, which include:
- Dilating blood vessels - this increases the blood flow to an injured area which helps fend off unwanted bacteria
- Stimulating gland secretion - this allows other helpful chemicals to join in the fight against foreign invaders
- Prompting the release of proteins from certain cells - this attracts other immune cells to the area to aid in destroying the harmful bacteria
Histamines are believed to play roles in many other bodily functions, including sleep regulation, suppression of certain sensations, sexual function, and more. Present in almost all animal body cells, histamines have a hand in almost everything.
