Any physical response you’ve had in the past—even a completely normal reaction to a physical trauma—can be reactivated years later by a feeling similar to the one you experienced at the time of that event. How is that possible?

Modern neuroscience is helping us understand exactly how this works. There is a specific area of the brain that constantly coordinates information between your physical body and your emotional experience. This area, called the insula, is located in the cerebral cortex. The insula acts as a kind of internal “monitor,” continuously receiving signals from your body—heart rate, breathing, gut sensations—and integrating them with your emotions and conscious awareness.

The insula is constantly communicating with many other areas of the brain, as well as with several hormone-producing glands throughout the body. What’s important to understand is that this communication flows in both directions. Signals move from the body to conscious awareness, and from conscious or subconscious thought back into the body. In other words, your body influences your thoughts, and your thoughts influence your body—simultaneously.

Your conscious mind and your subconscious memory can activate the same physical systems. A simple example of subconscious memory triggering a physical response is when you reach for your wallet in your right pocket, and it’s not there. Instantly, you feel a wave of sensation move through your body—before you’ve had time to reason that it might be in your left pocket. Or when you reach for your phone in a familiar spot in your purse and don’t feel it, only to find it moments later at the bottom. That brief surge of fear happens automatically.

This response is part of a neurological and hormonal network often referred to as the HPA axis—the hypothalamus, pituitary gland, and adrenal glands. This system works closely with what we commonly call the emotional brain, or limbic system. Its job is survival, not logic. These everyday examples help illustrate that there truly is no separation between mind and body.

Another powerful example involves emotional meaning layered onto physical experiences. If you fell down in public and felt embarrassed, careless, or foolish, you didn’t just experience a physical event—you created an emotional memory tied to it. Often, what people remember most about the fall isn’t the physical impact, but whether anyone saw them.

What actually occurred in your nervous system was the activation of the fight-or-flight response. Both the physical sensation and the emotional meaning were stored together in memory. Later on, any time you experience feelings such as embarrassment, carelessness, or feeling “stupid,” that same fight-or-flight response can be reactivated—even if there is no physical danger present.

Since these emotions can occur many times throughout the day, the survival system may be triggered repeatedly. Over time, this constant activation can exhaust the stress-response system. Research now shows that this kind of chronic stress load is a foundational contributor to inflammation, hormonal imbalance, immune dysfunction, and ultimately chronic disease.

Now consider a different possibility. Instead of feeling embarrassed or careless after the fall, imagine that your immediate response had been gratitude—thankful that you didn’t break anything, thankful that your body protected you. In that moment, you would have stored a completely different emotional memory alongside the physical event.

That choice would have created a different neurological pathway, processed by the limbic system as a positive or neutral experience rather than a threat. This pathway would not activate the fight-or-flight response in the future. Instead, it would reinforce a sense of safety and resilience.

This is why conscious awareness matters so deeply. When we intentionally engage the higher, thinking parts of the brain, we can reshape how experiences are stored in memory. Over time, this practice doesn’t just change our mindset—it changes our nervous system, our physiology, and ultimately, our health.

There truly is no separation between mind and body. They are in constant conversation, always listening, always responding.
