On this day of Thanksgiving, people around the United States are expressing gratitude for the bounty of their lives, but many may not realize that in doing so, they are also improving the quality of their health and increasing their life expectancies.
The scientific evidence is conclusive when it comes to mood, outlook, and health. Happy people live 7-10 years longer than unhappy people, and optimistic people have a 77% lower risk of heart disease than pessimistic people. But how can you become happier and more optimistic in your world view?
The How Of Happiness
In Sonja Lyubomirsky’s The How Of Happiness, the author teaches us how 50% of our propensity for happiness is based on a genetic set point, something we can’t influence very much, 10% is based on life circumstances (such as getting the promotion, finding The One, or achieving the creative dream), and 40% is “intentional activity” that we can influence with our behavior.
That means we can be up to 40% happier in our lives without changing our circumstances one bit, and one of the key intentional activities is the practice of gratitude.
Research shows that consistently grateful people are happier, more energetic, more hopeful, more helpful, more empathic, more spiritual, more forgiving, and less materialistic. They’re also less likely to be depressed, anxious, lonely, envious, neurotic, or sick.
In one study, one group of participants were asked to name five things they’re grateful for every day, while another group was asked to list five hassles. Those expressing gratitude were not only happier and more optimistic, they reported fewer physical symptoms, such as headache, cough, nausea, or acne. Other gratitude studies have shown that those with chronic illnesses demonstrate clinical improvement when practicing regular gratitude.
Severely depressed people instructed to list grateful thoughts on a website daily were found to be significantly less depressed by the end of the study when compared to depressed people who weren’t asked to express gratitude. And we know that depression is a significant risk factor for disease.
