An article authored by Arjun Walla shared some interesting scientific information backing what we always knew: gratitude literally impacts us on a molecular level.

According to the article, scientists have discovered that feelings of gratitude can actually change your heart and brain. Feeling gratitude can also be a great tool for overcoming depression and anxiety. Furthermore, scientists have discovered that the heart sends signals to the brain.

There are those people with seemingly very little who are overwhelmed with gratitude for a warm meal, rudimentary shelter, or some used clothing while so many of us who have all so much are always in search of more things to make us happy and fulfilled rather than appreciating what we have.

In a world where emotional intelligence isn’t really taught in school and the importance is put on striving for high grades, it’s no wonder so many people have difficulty feeling grateful. This is especially understandable if you’ve been brought up in the western world, which is full of consumerism and competition, a world where we’re constantly made to feel we are lacking so we need to strive for more.

Says Walla, happiness is a matter of perspective, and in a world where we are constantly made to feel like we are lacking and always ‘wanting’ more, it can be difficult to achieve or experience actual happiness. Many of us are always looking toward external factors to experience joy and happiness when really it’s all related to internal work. This is something science is just starting to grasp as well, as shown by research coming out of UCLA’s Mindfulness Awareness Research Center (MARC).
