“Mind over matter” is not simply a catchphrase. It is a truth based on what we know to be fact: that the brain, given the right set of directions, the right environment, and the proper stimuli, will always choose healing over disease.
The ability to fend off illness and disease depends on several factors, some of which are beyond our control, but the way we react to stress and the general health of our immune system are things we can influence. If we’re not able to change our response to stressors, we’ll find ourselves in a constant hormonal battle that will lead to serious health issues like hypertension, diabetes, and heart disease. The brain and the immune system are in constant communication in this delicate balance that can be disrupted by any kind of physical or emotional stress.
Ongoing stress makes us susceptible to illness and disease because the brain sends defense signals to the endocrine system, which then releases an array of hormones that not only gets us ready for emergency situations but severely depresses our immunity at the same time. Some experts claim that stress is responsible for as much as 90% of all illnesses and diseases, including cancer and heart disease. The way it does this is by triggering chemical reactions and flooding the body with cortisol that, among other things, decreases inflammation, decreases white blood cells and NK cells (special cells that kill cancer), increases tumor development and growth, and increases the rate of infection and tissue damage.
