By now you’ve heard about the benefits of keeping a gratitude journal – like better sleep, lowered stress, more happiness, even less illness. But what’s so important about writing our thoughts down instead of just thinking them? Gratitude expert and psychology professor, Robert Emmons, explains that writing things down makes us more aware of them and deepens their emotional impact. He also says not to hurry when journaling, but to “relish” the depth of your gratitude. You can journal anywhere, anytime, on anything. You don’t have to get fancy. And of course, there are apps for that.
