Mind-Body-Spirit
All three parts are important in your life and in determining who you are. What goes on in your mind influences every part of the body. Your body and your mind are affected by how connected you feel to your spirit (soul). Spirit is the life force within you that gives life, energy, and power. You are a spiritual being with a mind that affects every aspect of your body.
When your mind is healthy, your body can resist illness better.
When your body is healthy, your feelings are more positive.
When your spirit is renewed and energized, your mind is alert and your body feels good. The well-being of your spirit is linked to your mental, emotional, and physical health.
The connections among the mind, body, and spirit can lead to a person being healthy or the effects of stress on mind, body, and spirit connections can lead to illness
