Even more research is drawing a clear link between mindfulness meditation and lowered stress.


A new study in the journal Health Psychology shows an association between increased mindfulness and decreased levels of the stress hormone cortisol.


"This is the first study to show a direct relation between resting cortisol and scores on any type of mindfulness scale," study researcher Tonya Jacobs, a postdoctoral researcher at the University of California, Davis Center for Mind and Brain, said in a statement.


For the study, 57 people spent three months in a meditation retreat, where they were taught mindful breathing, observation skills, and cultivation of "positive" mental states like compassion.


At the beginning and end of the retreat, the participants also had their cortisol levels measured with a saliva test, and their mindfulness levels rated on a scale, which Jacobs explained in the statement "measured the participants' propensity to let go of distressing thoughts and attend to different sensory domains, daily tasks, and the current contents of their minds."


Researchers noted that the participants' mindfulness scores on the scale were higher at the end of the retreat than at the beginning. Plus, they found an association between increases in mindfulness and decreases in cortisol levels in the saliva.


However, it's important to note that this study did not use a control group to compare cortisol levels to. Researchers noted that future studies should include a larger group of participants and a study design that includes a control group.


This study joins a whole host of other research showing mindfulness meditation's stress-busting effects. For example, a 2007 study in the journal Proceedings of the National Academy of Sciences showed that going through integrative body-mind training (a type of meditation training) helped to lessen the body's release of cortisol and lower anxiety and fatigue levels in college students. And a 2008 study in the Journal of American College Health showed that meditation could reduce stress and boost forgiveness.

    When doctors underwent mindfulness meditation training, they <a href="http://www.huffingtonpost.com/2012/05/01/mindfulness-meditation-doctors_n_1456870.html" target="_hplink">listened better</a> and were less judgmental at home and at work, according to the <em>Academic Medicine</em> study.




  • People With Rheumatoid Arthritis


    Practicing mindfulness meditation exercises could help people with the painful condition to <a href="http://www.huffingtonpost.com/2011/12/28/mindfulness-meditation-rheumatoid-arthritis_n_1171685.html?1325055022&ref=health-news" target="_hplink">decrease their stress</a> and fatigue levels, according to a study from Oslo's Diakonhjemmet Hospital.

    In that study, published in the journal <em>Annals of Rheumatic Diseases</em>, the <a href="http://www.huffingtonpost.com/2011/12/28/mindfulness-meditation-rheumatoid-arthritis_n_1171685.html?1325055022&ref=health-news" target="_hplink">goal of the mindfulness meditation</a> exercises was to help people concentrate on their own thoughts, experiences and pain in the moment, without actively trying to avoid them or judge them. The researchers found that people who did the exercises had lower stress and fatigue measurements than people who didn't partake in the meditation.




  • The Elderly


    Practicing mindfulness meditation could help decrease feelings of <a href="http://www.huffingtonpost.com/2012/07/29/mindfulness-meditation-loneliness-elderly_n_1702112.html" target="_hplink">loneliness in the elderly</a>. The small study, published in the journal <em>Brain, Behavior & Immunity</em>, showed that undergoing an eight-week mindfulness meditation training program, as well as doing meditation exercises at home, was linked with lower feelings of loneliness <em>and</em> a reduction in the expression of genes known to be linked with inflammation.

    This finding is important because, among the elderly, loneliness is known to increase the risk for a <a href="http://www.huffingtonpost.com/2012/07/29/mindfulness-meditation-loneliness-elderly_n_1702112.html" target="_hplink">number of other health problems</a> -- including heart risks and even a premature death.




  • Stroke Survivors


    Practicing yoga for eight weeks helped stroke survivors to <a href="http://www.huffingtonpost.com/2012/07/31/yoga-stroke-balance-survivors-patients-_n_1724580.html" target="_hplink">improve their balance</a> in a study published in the journal <em>Stroke</em>.

    Improving balance among stroke patients is important for reducing the risk of falls. People who had balance problems, or feelings of dizziness and/or spinning, were five times more likely to fall than those without balance issues, according to an earlier 2003 study in <em>Stroke</em>.

    And in other research, presented at the annual meeting of the American College of Sports Medicine this year and conducted by the same researchers as the balance study, they found that yoga helped stroke survivors to <a href="http://www.huffingtonpost.com/2012/06/03/yoga-stroke-rehabilitation_n_1563208.html" target="_hplink">be more flexible</a>, be stronger, and have more endurance and strength.




  • Caregivers


    It's not just people with an ailment who can benefit from yoga -- people <em>caring</em> for the sick can be helped, too. A study in the <em>International Journal of Geriatric Psychiatry</em> found that caregivers who participate in meditation have <a href="http://www.huffingtonpost.com/2012/03/13/yoga-caregivers-meditation-kirtan-kriya_n_1342389.html" target="_hplink">decreased symptoms of depression</a> and even a decrease in cellular aging from stress.
