The holistic health model states that health is more than simply being free from illness. Holistic health believes that all parts of the body, mind, and spirit are intricately woven together. Because of that, each part of a person's overall health can be thrown off if one part isn't at optimal levels. For example, if a person is emotionally feeling anxious, it could cause stomach aches and/or headaches. In that case, there is nothing wrong with the nervous system or digestive system. The problem is a mental/emotional problem that is adversely affecting other parts of a person's health. It most closely relates to the health concept of wellness and the 7 dimensions of wellness.
What this means for full time health workers is that they need to concentrate on treating more than only physical symptoms. A person might be perfectly healthy, but an emotional mess. There might not be any immediate health symptoms, but some may develop later as a result. Or even worse, suicide because of the lack of emotional wellness. Health workers should be focusing on maintaining a person's overall wellness in order to best keep the person at optimal health.
