Gratitude is good for our bodies: Studies by Emmons and his colleague Michael McCullough suggest gratitude strengthens the immune system, lowers blood pressure, reduces symptoms of illness, and makes us less bothered by aches and pains. It also encourages us to exercise more and take better care of our health.
Grateful people sleep better: They get more hours of sleep each night, spend less time awake before falling asleep, and feel more refreshed upon awakening. If you want to sleep more soundly, count blessings, not sheep.
Gratitude makes us more resilient: It has been found to help people recover from traumatic events, including Vietnam War veterans with PTSD.
Gratitude strengthens relationships: It makes us feel closer and more committed to friends and romantic partners. When partners feel and express gratitude for each other, they each become more satisfied with their relationship. Gratitude may also encourage a more equitable division of labor between partners.
"Managers who remember to say “thank you” to people who work for them may find that those employees feel motivated to work harder. "
"When their week’s assignment was to write and personally deliver a letter of gratitude to someone who had never been properly thanked for his or her kindness, participants immediately exhibited a huge increase in happiness scores. This impact was greater than that from any other intervention, with benefits lasting for a month."
