An article authored in 2019 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 help overcome depression and anxiety. Furthermore, scientists have discovered that the heart sends signals to the brain, and not just the other way around.

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 look 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).
