Gratitude is a powerful emotion that conveys appreciation for a moment that has touched you in some way and moves you to express thankfulness. When you experience gratitude, your brain releases neurotransmitters such as dopamine and serotonin, resulting in a host of tangible benefits associated with positive thinking and emotions. Practiced regularly, gratitude literally rewires your brain to be more optimistic, flexible, and joyful, while simultaneously reducing stress and anxiety, building resilience to adversity, and strengthening your immune system, cardiac health, sleep hygiene, and more. These many positive changes to your health and well-being are ?the gratitude effect,? and because these effects are cumulative, the more you practice gratitude, the greater its impact over time.
