How is your body signaling to you?

Amazing characteristics of the Body’s Signaling System 
One of the most ingenious characteristics of the body’s sophisticated signaling system is its specificity. If you have a poison ivy rash on your arm, the relentless itchiness results from the release of histamine, the signal molecule that activates an inflammatory response to the ivy’s allergen. Since there is no need to start itching all over your body, the histamine is only released at the site of the rash.
Similarly, when a person is confronted with a stressful life experience, the release of histamine within the brain increases blood flow to the nervous tissues, enhancing the neurological processing required for survival. The release of histamine in the brain to deal with stress behaviors is restricted and does not lead to the initiation of inflammation responses in other parts of the body. Like the National Guard, histamine is deployed only where it is needed and for as long as it is needed.

Most of the Medical Industry’s Drugs have no Specificity
On the contrary, when you take an antihistamine to deal with the itchiness of an allergic rash, the ingested drug is distributed systemically. It affects histamine receptors wherever they are located throughout the whole body. Yes, the antihistamine will curb the blood vessels’ inflammatory response, dramatically reducing allergic symptoms.

However, when the antihistamine enters the brain, it inadvertently alters neural circulation that then impacts nerve function. That’s why people who take over-the-counter antihistamines may experience allergy relief and also the side effect of feeling drowsy.

  1. Thank you Dr Bruce for another clear and understandable explanation.

    BTW, after all theses years (and I’ve lost track of how many) I still do not take ‘thyroid replacement therapy’ and my MD is still somewhat mystified. I am forever grateful for our conversations that enabled me to find the courage to trust that my body knew the right things to do.
