How the Brain Works
Every thought you think causes your brain to secrete a chemical that runs down into your body and lands on specific receptor sites floating on the surface of your cells. These chemicals are messengers that tell your cells how to behave. The body interprets the chemicals as feelings. Dr. Candace Pert, the neurobiologist who discovered the opiate receptors in the brain calls them the molecules of emotion.
Thinking positive thoughts bathes the body in positive chemicals and imp…roves health. Thinking negative thoughts does the opposite; and causes physical illness.
The chemicals our brains secrete connect only to specific receptors, similar to a key fitting into a lock. The receptors vibrate at certain frequencies in order to attract specific chemicals to themselves. As our brains secrete these chemicals, our cells monitor the amount of chemicals they are receiving and adjust the number of receptor sites accordingly. Therefore, the more we think specific thoughts, the more receptors our cells will create to receive the plenteous flow of chemicals. When we attempt to change our thought patterns from negative to more positive, all those hungry receptor sites begin to scream, telling the brain to create more of that chemical, causing our physical self to work against our attempts at creating a healthier life.
This is the mechanism by which addiction works. Receptor sites throughout the body multiply in order to accommodate the flood of synthetic emotions/chemicals being fed to them, and quitting the addicting behavior/thoughts sends the physical body into spasms of withdrawal as those hungry receptor sites cry out to be fed.
The reason we have receptors for such chemicals as, say, heroin, is because our brains are capable of creating pain-killing, uplifting emotions (check out the link below). We call them endorphins. The “runners’ high” is an example of natural endorphins kicking in, but it takes way more effort than shooting up (although it is far less expensive). Unfortunately, as with any kind of an addiction, nothing in real life can ever match the intensity of the sensations created by heroin, porn (including the soft porn of romance movies) or any other addictive substance or process. Even workaholism is a chemically-based substitute for the healthy feelings that result from understanding how to build and maintain healthy relationships.
