Instead of taking a pill, taking in such spine-tingling wonders as the Grand Canyon, Sistine Chapel ceiling or Schubert’s “Ave Maria” may give a boost to the body’s defense system, according to new research
Scientists from the University of California Berkeley have linked positive emotions – especially the awe we feel when touched by the beauty of nature, art and spirituality – with lower levels of pro-inflammatory cytokines, which are proteins that signal the immune system to work harder.
“Our findings demonstrate that positive emotions are associated with the markers of good health,” said Jennifer Stellar, a postdoctoral researcher at the University of Toronto and lead author of the study, which she conducted while at UC Berkeley.
While cytokines are necessary for herding cells to the body’s battlegrounds to fight infection, disease and trauma, sustained high levels of cytokines are associated with poorer health and such disorders as type-2 diabetes, heart disease, arthritis and even Alzheimer’s disease and clinical depression.
It has long been established that a healthy diet and lots of sleep and exercise bolster the body’s defenses against physical and mental illnesses. But the Berkeley study, whose findings are published in the journal Emotion, is one of the first to look at the role of positive emotions in that arsenal.
“That awe, wonder and beauty promote healthier levels of cytokines suggests that the things we do to experience these emotions – a walk in nature, losing oneself in music, beholding art – has a direct influence upon health and life expectancy,” said UC Berkeley psychologist Dacher Keltner, a co-author of the study.
