Answer 2

Answer:

• Positive emotions like love, compassion, and appreciation, on the other hand, counteract the physiology of the stress response. They send up feel-good hormones like norepinephrine. Dopamine flows in the brain’s pleasure pathways. Heart rhythms relax into a more stable, coherent order. Gratitude, it turns out, may be one of the most powerful ways to get that “warm-glow’ feeling. Better yet, it seems like that warm glow may actually spread from one person to those in his near vicinity.
