Handwritten notes–whether to employers, to yourself, or to a loved one–makes you stand out. Science shows that going out of your way to hand-write a letter makes you more memorable because you go above and beyond.

But that’s not all.

One Kent State-conducted study even shows that people who hand-write thank you three times a month are happier and show fewer signs of depression.

A study from Yonsei University College of Medicine in Seoul, South Korea in 2017 also showed that students who spent at least four minutes practicing gratitude a day had a significantly lower heart rate than students who spent at least four minutes in anger.

Writing a letter isn’t just good for you, though. Whoever you’re writing to is also sure to get a surge of the feels when they read your heartfelt missive.

According to research co-conducted by Amit Kumar, an assistant professor of marketing at the University of Texas at Austin’s McCombs School of Business, however awkward you might think writing a letter of gratitude to someone may be, his research shows the opposite. The thanks is likely to make someone’s day and help form a lasting relationship.

There is tons more research confirming the benefits of letter writing, but it all draws the same conclusion. Showing how much you care results in better moods for everyone involved and even has health benefits.
