The research behind writing as healing
Initially, Dr. James Pennebaker was curious about a study showing that people with secrets have more health problems, and he wondered if sharing those secrets would improve their health--and it did. But some secrets are too personal or painful to share, and Dr. Pennebaker found that just writing down the secrets, even if you immediately destroy the paper, had the same positive effect. And it also turns out that even those who don't have secrets per say but other kinds of emotional burdens--whether it's going through a divorce, handling the transition into college, coping with an abusive childhood, or dealing with a terminal illness--can relieve their traumas through writing. And the positive effects are wide-reaching and lasting. Those who write are sick less often, sleep better, or (for students) see improved grades.
Basically, after experiencing a trauma, our minds require extra processing power to make sense of the experience, which draws energy from other areas of our lives. By writing, we allow our minds to resolve the trauma and assimilate it, so we can be unburdened in our daily lives again. That can lead to better concentration, improved sleep, and more fulfilling relationships.
