Feeling better – Lifestyle management for chronic mental disorders In this module we have learned about three risk factors associated with poor physical health: overweight, lack of physical activity and smoking. All three factors are more common in patients with chronic mental disorders than in the general population and may be associated with a tangible reduction of life expectancy.
