Relation between psyche and health

As we all know, Psyche and health are closely related.
Our brain is the central part of nervous system that controls and thereby regulates all other bodily activities. So, for a healthy body, maintaining a healthy mind is always important. That is how we can maintain total health.
Our mind can function well, only if it is well fed with all the required nutrients and ofcourse when it is maintained stress free. Also our physical activity should always balance the mental activity, that we get face in our daily life. Ours is a body mind system, what ever the mind says and believes in, the body can achieve; likewise, healthy body regulates healthy psyche. Therefore, we have to nourish both our psyche and body, in a positive healthy environment.
