Researchers say gratitude offers a “unique stress-buffering effect” when it comes to both reacting to, and recovering from, acute psychological stress. Study authors add that adopting a more thankful worldview can even promote better cardiovascular health. Study authors chose to focus on this consideration, as well as whether or not affect-balance moderates the relationship between gratitude and cardiovascular reactions to acute psychological stress. This means, study authors say, that gratitude promotes a unique stress-buffering effect on both reactions to and recovery from acute psychological stress. In conclusion, study authors believe these findings hold clinical usefulness.
