I just read an article in Spirituality & Health by Traci Pedersen. She reports on recent research out of UC Berkeley showing that immersion in the beauty of nature, art and/or spirituality – in other words, becoming awestruck or bowled over by a sense of wonder - is associated with lower levels of inflammatory cytokines.
Cytokines are proteins that prod the immune system to crank it up a notch, which is generally a good thing, especially for dispatching infections or cancer. But we also know that chronic inflammation from an overproduction of cytokines can wreak cumulative havoc on health and longevity.
So, this study of 200 subjects suggests it wouldn't be a bad idea to deliberately seek out activities that catalyze your feelings of awe.
