Prayer and meditation lower blood pressure. Studies find that religious and spiritual people are healthier than those who are not.
Prayer is a conversation with the spiritual power greater than the soul. Meditation is a monologue within the soul. Both connect the human with creation and the spiritual realm. It is not about what you call God, or the greater power you choose to recognize. It is all on you, human, and your faith to reach beyond yourself.
Consider trying daily prayer or meditation.
