Several researchers, such as Alice Flaherty, a neuroscientist at Harvard University in the US, have suggested that blogging could have a therapeutic value. It is well known that writing about personal experiences, especially negative thoughts, can have a positive biological effect on a person.
For example, writing has been shown to increase memory, aid sleep and help people to recover faster after surgery. We don’t know how this works because the area associated with such communication within the limbic system is located too deep within the brain to study. Nevertheless, I suspect it won’t be long before hospitals are prescribing blogging to patients to help them recover from surgery or to boost the immune system in cancer patients.
