Studies show that meditation is associated with improvement in a variety of psychological areas, including stress, anxiety, addiction, depression, eating disorders and cognitive function, among others. There’s also research to suggest that meditation can reduce blood pressure, pain response, stress hormone levels and even cellular health. But what does it actually do to the body. . The cells and neurons in the brain are constantly making new connections and disrupting old ones based on response to stimuli, a quality that researchers call experience-based neuroplasticity. This affects the neural circuits of the brain, which in turn affects how we respond to situations. It also affects the actual structure of our brains — thickening some areas and making others less dense.
Think of the end of a neuron as a hand with thousands of ‘fingers’
said Dr. Sara Lazar, a neuroscientist at Massachusetts General Hospital who studies mindfulness meditation. “The number of fingers relates to the number of interconnections between neurons and that number can change — one reason it can change is due to stress”.
