If the state of the publishing industry is driving you crazy, I suggest you go out for a walk. Recent studies have revealed “strong evidence to demonstrate the ability of exercise to in fact treat mental illness and have significant benefits on a neurotrophic, neurobiologic basis," (Douglas Noordsy, MD, at Psych Congress 2012: US Psychiatric and Mental Health Congress.). Translated into English this means that in some cases, the benefits from exercise have been shown to match that of psychiatric drugs and to extend remission in the long term. The strongest evidence was seen in cases of depression (surprise!) but was also significant for anxiety and dementia. While evidence about the impact of exercise on core symptoms of more serious psychiatric disorders is less strong, in one study, patients with chronic schizophrenia who jogged for 40 minutes 3 times a week showed significant decreases in symptoms of depression, anxiety, phobias and obsessive compulsive behaviours.
