Dr. Koenig sees religion as having direct preventive health effects in two ways. "First, research shows that religious people with a strong social support network often have their diseases diagnosed earlier, become actively involved in their treatments, and follow their care givers’ instructions more closely than do less religious people." "The second health-enhancing direct effect of religious faith is the avoidance of unhealthy habits. For example, healthier lifestyles among the religiously involved lead to lower rates of pulmonary disease such as emphysema and lung cancer (consequences of smoking), lower levels of liver disease such as cirrhosis (stemming from alcohol abuse), and significantly lower levels of other substance abuse than exist among the general population." Dr. Koenig extends this picture of the benefits of an active religious life to include reductions in the rates of divorce, crime, suicide, and many other common problems. Dr. Koenig is clear that he is not advocating faith instead of modern scientific medicine, but he does conclude that actively practiced religious faith enhances the benefits of medicine in both prevention and treatment.
