Narrator: This is Science Today. Understanding how the mind-body approach may impact the immune system is a rather new area of investigation and really did not begin to emerge as a scientific discipline until about ten years ago. Dr. Michael Irwin, a researcher at UCLA's Jonsson Cancer Center has been studying how mind-body interventions may improve well-being and immunity.
Irwin: Recent work done here at UCLA has found that the practice of a very simple behavioral technique called Tai Chi Cha, which is a variant of Tai Chi, can significantly improve the immune system of older adults.
Narrator: Irwin specifically looked at an immune cell that is predictive of risk for developing a particular kind of viral infection called shingles, which affects older people, as well cancer and AIDS patients.
Irwin: I'm not suggesting that they forgo vaccinations against viral illnesses, but rather that this complimentary approach can augment at least this one aspect of the immune system that may promote health.
