Religion is nothing but a disciplinary way, it shows the way how you behave and how you maintain your Life. If you follow the instructions of any religion then you can lead a peaceful life. Discipline can bring your good health. So regular life is the way of making good health.
So there is a relationship between religion and good health.
If taken in moderation. Too much of it, and you become paranoid, schizophrenic, serial or mass murderer.
Regardless, it is a very dangerous poison IMHO. Just like alcohol or drugs, religious ideology can fuck up your thinking.
I agree. Too much religion has a negative impact on the mental, and over time and on the person's physical health.
