Science has shown that writing may actually have therapeutic effects. These benefits are especially prominent when writers write about their personal experiences, thoughts, and emotions. In addition to serving as a stress-coping mechanism, writing also many physiological benefits. Research has shown that writing improves sleep, memory, immune system activity, as well recovery after injury. One study has shown that cancer patients who engage in expressive writing reported to have felt better physically and mentally after treatment, in comparison to patients who did not engage in such activity. Perhaps this is why the blogosphere has seen such remarkable growth in recent years. New evidence has indicated that blogging may trigger dopamine release, similar to stimulants like music or running. Dopamine is the pleasure hormone associated with physical and mental activities perceived to be rewarding. Blogging about stressful experiences may also provide relief, primarily due to the placebo effect.
