The relation between brain activity and the immune system was evaluated by assessing immune responses in 20 healthy women who manifested extreme differences in the asymmetry of frontal cortex activation. One group showed extreme and stable left frontal activation; the other group showed extreme and stable right frontal activation. As predicted, women with extreme right frontal activation had significantly lower levels of natural killer cell activity (at effector:target cell ratios of 33:1 and 11:1) than did left frontally activated individuals. This difference did not extend to two other immune measures, lymphocyte proliferation and T-cell subsets. However, higher immunoglobulin levels of the M class were observed in the right frontal group. In this study, the immune patterns could not be accounted for by plasma cortisol levels, anxiety- and depression-related symptomatology, or recent health histories. These findings support the hypothesis that there is a specific association between frontal brain asymmetry and certain immune responses.
This position paper advocates for early childhood teachers and parents to regularly use of mindfulness practices themselves and with very young children. An understanding of 'mindfulness' is important because it can provide ways to support children during their sensitive years and sow seeds of kindness, tolerance and peace in our fast paced, competitive, consumerist culture. In addition, in times of trauma, mindfulness techniques offer teachers and parents ways to calm themselves and the children close to them. The value of using mindfulness techniques with children and for demonstrating mindfulness as adults is well supported by research (McCown, Reibel and Micozzi, 2010; Saltzman and Goldin, 2008).
