A year of kindness and forgiving others
These days from a common soldier to a General, all are aware of their personal health benefits from exercise to selecting foods. But most people are not familiar with the importance of hormones. We are not aware of the significant relationship between the power of practicing forgiveness, gratitude, donation and having a sound body and mind.
Hormones coordinate the physiology and behavior of individuals by regulating, integrating, and controlling bodily functions. Over evolutionary time, hormones have often been co-opted by the nervous system to influence behavior to ensure reproductive success. Gonadal hormones are produced by the gonads (the ovaries and testes) in response to other precursor hormones found in the pituitary gland and other brain areas.
Although most researches that are correlated to 'why good habits (like forgiveness, kindness, giving) makes us feel better?' have centered around, these gonadal hormones also impact brain chemistry and circuitry, and hence influence emotions, mood and behavior.
Forgiveness especially engages the parasympathetic nervous system, which helps our immune system. The hormone Oxytocin is so influential that some call it "the love hormone"; it plays a role in trusting people and connection to others. It is the hormone mothers produce when they breastfeed, cementing their bond with their babies. In addition to boosting oxytocin and dopamine, being kind can also increase serotonin, a neurotransmitter that helps regulate mood.
