Religion and Medicine

Should religion and medicine intertwine? I know that there is proofs that religion has helped many people to have better health and a better life, and if that is what people have found works for their health who can tell them to do otherwise. It is working and that is what people really want in the end. But should doctors be prescribing religion to their patients, that is just absurd. To tell them to do some religious practices like meditation or yoga is in fact suggested physical medicine, just with a different name. We know that these exercises do in fact help with circulation and oxygen to the muscles, therefore they are indeed religious exercises and medical ones, just like stretching before a game. There must be a distinction between the things in religion that are medical and those that aren't. Then there can be a distinction between what can be prescribed, that which is medical like yoga and meditation. We cannot tell people to pray to this God or that in the medical field, because that isn't medicine, and it isn't legal. Plus, doctors are not trained in all the different fields of religion and medicine to be able to say which god will be better for each situation. There clearly can be some things that can cross over, but it must be understood that just because a religion practices something that it is medicine; and that there are some religious exercises that are medically proven to be healthy.
