There is a great deal of scientific literature that analyzes how religious belief impacts physical and mental health. Religiosity has been documented as having both positive and negative effects on people’s health, depending on exactly what they believe. For example, belief in God can reduce anxiety, but not if you think God is punishing you.

A new study found that high religiosity was associated with better physical health, unless the person believed in miracles. The researchers concluded that belief in miracles may make people less likely to take a proactive approach to their health since they think it is in God’s hands. If they are just hoping that a miracle will save them, they may not work as hard to get healthier.

The researchers suggested that doctors should encourage their patients to take care of their body as a “sacred duty” instead of just having them rely on miracles. This could motivate the patient to be more proactive without threatening their beliefs.

Again, religion has been associated with many positive health outcomes. Believing that “God has a plan” can help reduce the uncertainty in our lives, which is supported by neuroscience research. However, taking this to the point of avoiding medical treatment can produce negative health outcomes.
