“Kindness is more than behavior. The art of kindness means harboring a spirit of helpfulness, as well as being generous and considerate, and doing so without expecting anything in return. Kindness is a quality of being. The act of giving kindness often is simple, free, positive and healthy. Physiologically, kindness can positively change your brain. Being kind boosts serotonin and dopamine, which are neurotransmitters in the brain that give you feelings of satisfaction and well-being, and cause the pleasure/reward centers in your brain to light up. Endorphins, which are your body’s natural pain killer, also can be released.”.
