No one really knows for sure how spirituality is related to health. However, it seems the body, mind, and spirit are connected. The health of any one of these elements seems to affect the others.
Some research shows a connection between your beliefs and your sense of well being. Positive beliefs, comfort, and strength gained from religion, meditation, and prayer can contribute to well being. It may even promote healing. Improving your spiritual health may not cure an illness, but it may help you feel better. It also may prevent some health problems and help you cope better with illness, stress, or death.
1 Corinthians 6:19-20
Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own;
you were bought at a price. Therefore honor God with your bodies.
