What do Google, Target and General Mills have in common?

Meditation.

Increasingly, big companies are embracing the practice with Eastern roots, providing courses and opportunities for employees to find their center, the Financial Times Magazine reported.

"It's about training our minds to be more focused, to see with clarity, to have spaciousness for creativity and to feel connected," General Mills deputy general counsel Janice Marturano told the magazine. Marturano founded the program at the company. "That compassion to ourselves, to everyone around us -- our colleagues, customers -- that's what the training of mindfulness is really about."

Google's mindfulness course, for one, is called "Search Inside Yourself," and it's already been taken by more than 1,000 employees at the company, the New York Times reported.

The creator of the course, Mirabai Bush, told the Chicago Tribune that while some people aren't convinced about the effects of mindfulness, it has been shown in research to decrease stress levels.

Google spokeswoman Katelin Todhunter-Gerberg told the Associated Press that she has used mindfulness to help her be less irritable and take things less to heart.

Even though mindfulness has Buddhist roots, the author of the Financial Times Magazine article said that most leaders of companies promoting mindfulness to their employees that he spoke to are not Buddhist.

And it's not just businesses that are utilizing the practice -- business schools are also teaching students about mindfulness, the Wall Street Journal reported, including Claremont Graduate University and Harvard Business School.

The Journal explains the draw:

While the idea of mindfulness originates in the serious practice of meditation, B-school faculty say it has many applications for executives who aren't looking for a spiritual fix but simply want to clear their heads and become aware of reflexive, emotional reactions that can lead to bad decisions.

  • It Makes Your Brain Plastic

    Quite literally, sustained meditation leads to something called neuroplasticity, which is defined as the brain's ability to change, structurally and functionally, on the basis of environmental input. For much of the last century, scientists believed that the brain essentially stopped changing after adulthood. But research by University of Wisconsin neuroscientist Richard Davidson <a href="http://brainimaging.waisman.wisc.edu/publications/2008/DavidsonBuddhaIEEE.pdf" target="_hplink">has shown that experienced meditators exhibit high levels of gamma wave activity</a> and display an ability -- continuing after the meditation session has attended -- to not get stuck on a particular stimulus. That is, they're automatically able to control their thoughts and reactiveness.

  • It Increases Gray Matter

    A 2005 study on American men and women who meditated a mere 40 minutes a day <a href="http://www.time.com/time/magazine/article/0,9171,1147167-2,00.html" target="_hplink">showed that they had thicker cortical walls than non-meditators</a>. What this meant is that their brains were aging at a slower rate. Cortical thickness is also associated with decision making, attention and memory.

  • It Can Be Better Than Sleeping

    In a 2006 study, college students were asked to either sleep, meditate or watch TV. They were then tested on their alertness by being asked to hit a button every time a light flashed on a screen. The meditators <a href="http://www.time.com/time/magazine/article/0,9171,1147167-2,00.html" target="_hplink">did better than the nappers and TV watchers</a> -- by a whole 10 percent.

  • It's Better Than Blood Pressure Medication

    In 2008, Dr. Randy Zusman, a doctor at the Massachusetts General Hospital, asked patients suffering from high blood pressure to try a meditation-based relaxation program for three months. These were patients whose blood pressure had not been controlled with medication. After meditating regularly for three months, <a href="http://www.npr.org/2008/08/21/93796200/to-lower-blood-pressure-open-up-and-say-om" target="_hplink">40 of the 60 patients showed significant drops in blood pressure levels</a> and were able to reduce some of their medication. The reason? Relaxation results in the formation of nitric oxide which opens up your blood vessels.

  • It Can Protect Your Telomeres

    Telomeres -- the protective caps at the end of our chromosomes -- are the new frontier of anti-aging science. Longer telomeres mean that you're also likely to live longer. Research done by the University of California, Davis' Shamatha Project <a href="http://www.guardian.co.uk/lifeandstyle/2011/apr/24/meditation-ageing-shamatha-project" target="_hplink">has shown that meditators have significantly higher telomerase activity that non-meditators</a>. Telomerase is the enzyme that helps build telomeres, and greater telomerase activity can possibly translate into stronger and longer telomeres .

  • It Can Slow The Progression Of HIV

    A 2008 study on HIV positive patients found that, after an eight-week meditation course, patients <a href="http://www.sciencedaily.com/releases/2008/07/080724215644.htm" target="_hplink">who'd meditated showed no decline in lymphocyte content</a> compared with non-meditators who showed significant reduction in lymphocytes. Lymphocytes or white blood cells are the "brain" of the body's immune system, and are particularly important for HIV positive people. The study also found that lymphocyte levels actually went up with each meditation session. However, due to the small sample size -- only 48 volunteers -- it's harder to draw definitive conclusions.

  • Its Pain Relieving Properties Beat MorphIne

    Earlier this year, a study conducted by Wake Forest Baptist University found that <a href="http://www.physorg.com/news/2011-04-demystifying-meditation-brain-imaging.html" target="_hplink">meditation could reduce pain intensity by 40 percent and pain unpleasantness by 57 percent</a>. Morphine and other pain-relieving drugs typically show a pain reduction of 25 percent. Meditation works by reducing activity in the somatosensory cortex and increasing activity in other areas of the brain. This study also had a small sample size, making it harder to draw definite conclusions.
