It seems to me that the important point about mind/body connections isn't that stress generally can affect physical processes or bodily systems, including the immune system. This is a given among most of those involved in mind/body research. The more important question is how psychological conflicts affect specific parts of the body and the specific psychological and physiological reasons for how this happens. For example, what is the specific mind/body explanation about how a primary caregiver's over attention to a child leads to asthma? Similarly, what is the specific mind/body explanation for why common colds and respiratory illnesses seem to increase in numbers during the Christmas holidays?
Research into these complicated mind/body issues ultimately could lead to a more healthy integration of mind/body medical treatment.
