05 Sep 2018 --- More than one in four adults globally – amounting to 1.4 billion people – are physically not active enough, with inactivity levels reaching one in three adults in some countries, new data published in The Lancet Global Health show. Policies to increase the physical activity levels of populations need to be prioritized and scaled up urgently to stave off the risk of poor health, note the involved World Health Organization experts. Regular physical activity is proven to help prevent and treat noncommunicable diseases (NCDs) such as heart disease, stroke, diabetes and different types of cancer. It has also been linked to improved mental health, quality of life and well-being. Moreover, it helps prevent hypertension and obesity.
