Recent research done by the Touch Research Institute has demonstrated that touch triggers a cascade of chemical responses, including a decrease in urinary stress hormones (cortisol, catecholamines, norepinephrine, epinephrine), and increased serotonin and dopamine levels. The shift in these bio-chemicals has been proven to decrease depression (Field, 1998, 2014). Hence, touch is good medicine. It also enhances the immune system by increasing natural killer cells and killer cell activity, balancing the ratio of cd4 cells and cd4/cd8 cells. The immune system's cytotoxic capacity increases with touch, thus helping the body maintain its defense against pathogens (Field, 1998).
