From Dr. Jay Kumar - The Neuroscience of Health & Happiness
Sep-29-2011

So what makes you happy? What is the connection between your brain and health? You may be surprised to learn that recent advances in neuroscience offer a deeper understanding of how a healthy brain equals a healthy body and being! A phrase I advance is that happiness is not something that happens to you, but rather happiness is something you choose. We all want to lead a happy and healthy live, but one key to cultivating health and happiness may reside in your brain, and more specifically with the power of your thoughts. In this first of two posts, I discuss the neurobiological component to happiness and what the latest research in neuroscience provides for you to cultivate more happiness and wellbeing in your life.

One of the greatest discoveries to come out of neuroscience in the past couple of decades is the concept of neuroplasticity. Basically, neuroplasticity describes the ability for our brain to rewire and restructure its neural structure and anatomy. A key phrase in neuroscience is, "Neurons that fire together wire together." What this means is that over time our collective experiences and thoughts that we repeat about who we are and our environment become neurologically wired in our brain. In essence our psychology creates our biology. As we experience the various thoughts and feelings throughout our day, they actually leave traces behind in the neural structure of the brain. If you spend your entire day worrying about what others think about you or thinking about how miserable your life is, those very thoughts begin to form a neural network that wires together cementing that concept in your mind. Conversely, if we can cultivate more gratitude, self-forgiveness, and compassion toward ourselves, we can begin to rewire these "neural nets of negativity" into a healthy brain and being.

The neuropsychologist, Dr. Rick Hanson, nicely states, "The mind is like Velcro for negative experiences and Teflon for positive ones." I'm sure many of us can relate to this idea, but why is that our minds tend to remember the painful, negative experiences but not so much the joyous, happy moments? There's actually a neurobiological answer that has to do with something called a "negativity bias." At the University of Washington a study revealed how a negative experience remains wired into our brain more strongly than a positive one. In fact, it takes up to five positive experiences to outweigh a negative thought! Neurobiologists believe that this "negative bias" of the human brain was an evolutionary trait that helped early humans survive by allowing the brain to react to, remember, and recall life-threatening experiences. Imagine you were an early human chased by a lion; your brain would store that information into a neural net, recalling that memory as a survival mechanism. The lesson is that in order to experience authentic happiness, we actively have to focus on the positive to overcome the negative experiences in our life that our brain has imprinted into our consciousness.
