More mindfulness = less stress

Focusing on the present rather than letting the mind drift may help to lower levels of the stress hormone cortisol, new research from the the University of California, Davis, suggests.

"This is the first study to show a direct relation between resting cortisol and scores on any type of mindfulness scale," said Tonya Jacobs, a postdoctoral researcher at the UC Davis Center for Mind and Brain and first author of a paper describing the work, published this week in the journal Health Psychology.

High levels of cortisol, a hormone produced by the adrenal gland, are associated with physical or
emotional stress. Prolonged release of the hormone contributes to wide-ranging, adverse effects on a number of physiological systems.

Mindfulness includes the ability to focus mental resources on immediate experience, which can be improved by meditation training.

According to Jacobs, training the mind to focus on immediate experience may reduce the propensity to ruminate about the past or worry about the future, thought processes that have been linked to cortisol release.
"The idea that we can train our minds in a way that fosters healthy mental habits and that these habits may be reflected in mind-body relations is not new; it's been around for thousands of years across various cultures and ideologies," Jacobs said. "However, this idea is just beginning to be integrated into Western medicine as objective evidence accumulates. Hopefully, studies like this one will contribute to that effort."
