As early as 1992, a study was published supporting the connection between the body and the mind, and more recent studies show that our mental health affects our physical health. A classic example is fear; if you are in a situation where you experience fear, the body responds with a "fight or flight" reaction. In his book "The Emotion Code," Dr. Bradley Nelson describes three things that happen when we experience emotion:
1. We develop an emotional frequency.
2. We experience the emotion and all the thoughts and physical sensations that accompany it.
3. We process the emotion and move on.
According to a study published in 2017, the emotional processing stage occurs in the limbic system of the brain, which is also responsible for survival and regulates body temperature, blood pressure, and blood sugar levels. As we constantly process new information, there is always an automatic response from our nervous system, which sends signals to the body and triggers emotional reactions that correspond to the experience. In other words, our emotions come from what the nervous system tells our body and us.
