Research led by the Black Dog Institute has revealed that even a small amount of physical activity, as little as one hour each week, can protect against depression, regardless of age, gender or current fitness level. Depression is a serious public health issue with around one million Australians currently diagnosed. We also know that up to 20 percent of the Australian population doesn’t undertake any regular physical activity, which may significantly increase their risk of developing depression in their lifetime. Our ‘Exercise Your Mood’ campaign (April 30 – May 6) aims to change these statistics by encouraging people to improve their mental fitness by taking on at least one hour of exercise each week. Though it can be hard to take the first step, one hour is a very achievable goal and something we’d like to encourage your readers to build into their weekly routine. If already on track, keep up the good work! Your mental health will thank you for it.
