In several studies, mindfulness meditation appeared to increase levels of T-cells or T-cell activity in patients with HIV or breast cancer. This suggests that mindfulness could play a role in fighting cancer and other diseases that call upon immune cells. Indeed, in people suffering from cancer, mindfulness appears to improve a variety of biomarkers that might indicate progression of the disease.  In another study, elderly participants were randomly assigned to an eight-week Mindfulness-Based Stress Reduction (MBSR) course or a moderate-intensity exercise program.

Studies suggest that long-time meditators may have greater telomere lengths. In one experimental study, researchers found that breast cancer survivors who went through MBSR preserved the length of their telomeres better than those who were on a waitlist. However, this study also found that general supportive therapies impacted telomere length; so, there may not be something special about MBSR that impacts cell aging.

We’ll be fidgety. As soon as we attempt to sit still, during meditation or any other time, it’s almost as if we can’t help but scratch an itch, stretch our neck, or cross and uncross our legs.

“The type of meditation matters,” explain postdoctoral researcher Bethany Kok and professor Tania Singer. “Each practice appears to create a distinct mental environment, the long-term consequences of which are only beginning to be explored.” How much meditation is enough? That also depends. This isn’t the answer most people want to hear. Many of us are looking for a medically prescriptive response (e.g., three times a week for 45-60 minutes), but the best guide might be this old Zen saying: “You should sit in meditation for twenty minutes every day—unless you’re too busy. Then you should sit for an hour.” To date, empirical research has yet to arrive at a consensus about how much is “enough.

, it might help to practice being in the present moment. For example, throughout the day you could notice when your attention wanders to thoughts about the past or anticipation of the future, and redirect your attention back to just one thing—like your breath, your body, or something in your immediate surroundings.

If we have trouble meditating at first, that’s okay. It happens to all of us. Even if we find ourselves wondering if we’re meditating correctly, don’t forget: they’re just thoughts.

Those who learned mindfulness had significantly greater reductions in their systolic and diastolic blood pressure than those who learned progressive muscle relaxation, suggesting that mindfulness could help people at risk for heart disease by bringing blood pressure down.

Not bad for a few minutes of sitting in silence, right? And it just gets better from here. Read on to learn more about meditation and how to start meditating yourself.

Meditation does have an impact on physical health—but it’s modest. Many claims have been made about mindfulness and physical health, but sometimes these claims are hard to substantiate or may be mixed up with other effects. That said, there is relaxing sounds some good evidence that meditation affects physiological indices of health. We’ve already mentioned that long-term meditation seems to buffer people from the inflammatory response to stress. In addition, meditators seem to have increased activity of telomerase, an enzyme implicated in longer cell life and, therefore, longevity. But there’s a catch. “The differences found [between meditators and non-meditators] could be due to factors like education or exercise, each of which has its own buffering effect on brains,” write Goleman and Davidson in

Meditation creates the conditions for us to see things more clearly, feel calmer and content, and be kind to ourselves and others no matter what’s happening in our lives.

To better understand the power of focus and awareness, consider an affliction that touches nearly all of us: email addiction. Emails have a way of seducing our attention and redirecting it to lower-priority tasks because completing small, quickly accomplished tasks releases dopamine, a pleasurable hormone, in our brains.

, to demonstrate how MBCT enables people to relate mindfully to the self and with others. The key, it seems, lies in the way MBCT enhances relationships: Less stress about relationships in turn helps prevent future episodes of depression. Three specific themes emerged from the study:

You’ll be surprised how fast it goes by. Add a minute or two with each successive session until you find the ideal duration for your daily practice.
