Positive psychology
Gratitude, the feeling of appreciation or thanks, has gained a lot of attention in the field of positive psychology. Some studies have found that those who are habitually grateful are happier than those who are not. Furthermore, studies suggest that feelings of gratitude may even possess mental and physical health benefits. Positive psychology strives to develop methods by which one can consistently enhance gratitude levels. Furthermore, the maintenance of a gratitude journal can help relieve depressive symptoms.
