Allergens are usually harmless substances capable of triggering responses that begin in the immune system and result in allergic reactions. For example, if you have an allergy to pollen, your immune system identifies pollen as an invader in the body. The immune system then responds by releasing inflammatory chemicals that typically cause symptoms in the nose, throat, eyes, ears, skin, or roof of the mouth. In addition to pollen, other common allergens include dust mites, animal dander, mold, medications, insect venoms and various foods.
First off, it must be understood that our brain controls all activities and structures in our body through the communication pathways in our spine. These nerves, originating in the brain, exit through spaces in the spinal column to supply every structure in your body. If the communication is blocked by any factor, most commonly misalignment of bones in the spine, dysfunction of that structure supplied by that nerve occurs. Regarding the case of allergies, the nerves supplying the immune system have been damaged by the bones in your spine, causing them to be hyperactive. As long as our nerves are communicating with our immune system properly, we can continue to successfully adapt to daily stress.
