Studies have shown that giving triggers the brain’s dopamine-rich reward system. When you give, you secrete “feel good” chemicals in your brain, such as serotonin (a mood-mediating chemical), dopamine (a feel-good chemical), and oxytocin (compassion and bonding chemical).
Studies also show that when people donate to charity, the portion of the brain responsible for feelings of reward is triggered. The brain releases feel-good chemicals, spurring you to perform more kind acts.
