As we launch into Thanksgiving week, consider this: Research shows that feeling grateful doesn't just make you feel good. It also helps — literally helps — the heart.

It fends off depression, stress and anxiety, which can increase the risk of heart disease, says Paul Mills, a professor of family medicine and public health at the University of California San Diego School of Medicine. Mills specializes in disease processes and has been researching behavior and heart health for decades. He wondered if the very specific feeling of gratitude made a difference, too.
