Meditation reduces loneliness

15.08.2012
UCLA study also finds that mindfulness technique benefits immune system

Many elderly people spend their last years alone. Spouses pass and children scatter. But being lonely is much more than a silent house and a lack of companionship. Over time, loneliness not only takes a toll on the psyche but can have a serious physical impact as well.

Feeling lonely has been linked to an increased risk of heart disease, Alzheimer's disease, depression and even premature death. Developing effective treatments to reduce loneliness in older adults is essential, but previous treatment efforts have had limited success.

What to do? Researchers at UCLA now report that a simple meditation program lasting just eight weeks reduced loneliness in older adults. Further, knowing that loneliness is associated with an increase in the activity of inflammation-related genes that can promote a variety of diseases, the researchers examined gene expression and found that this same form of meditation significantly reduced expression of inflammatory genes.

In the current online edition of the journal Brain, Behavior and Immunity, senior study author Steve Cole, a UCLA professor of medicine and psychiatry and a member of the Norman Cousins Center for Psychoneuroimmunology at UCLA, and colleagues report that the two-month program of mindfulness-based stress reduction (MBSR), which teaches the mind to simply be attentive to the present and not dwell in the past or project into the future, successfully reduced the feelings of loneliness.

Remarkably, the researchers said, MBSR also altered the genes and protein markers of inflammation, including the inflammatory marker C-reactive protein (CRP) and a group of genes regulated by the transcription factor NF-kB. CRP is a potent risk factor for heart disease, and NF-kB is a molecular signal that activates inflammation.

Inflammation is a natural component of the immune system and can help fight a wide variety of bodily insults, ranging from infections to a whack by a hammer. But chronic inflammation is now known to be a primary player in the pathology of many diseases and psychological disorders.

"Our work presents the first evidence showing that a psychological intervention that decreases loneliness also reduces pro-inflammatory gene expression," Cole said. "If this is borne out by further research, MBSR could be a valuable tool to improve the quality of life for many elderly."

In the study, 40 adults between the ages of 55 and 85 were randomly assigned to either a mindfulness meditation group or a control group that did not meditate. All the participants were assessed at the beginning and the end of the study using an established loneliness scale. Blood samples were also collected at the beginning and end to measure gene expression and levels of inflammation.

The meditators attended weekly two-hour meetings in which they learned the techniques of mindfulness, including awareness and breathing techniques. They also practiced mindfulness meditation for 30 minutes each day at home and attended a single daylong retreat.

These MBSR participants self-reported a reduced sense of loneliness, while their blood tests showed a significant decrease in the expression of inflammation-related genes.

"While this was a small sample, the results were very encouraging," said Dr. Michael Irwin, a professor of psychiatry at the Semel Institute for Neuroscience and Human Behavior at UCLA and director of the Cousins Center. "It adds to a growing body of research that is showing the positive benefits of a variety of meditative techniques, including tai chi and yoga."

Just last month, for example, Dr. Helen Lavretsky, a UCLA professor of psychiatry and a Cousins Center member, published a study showing that a form of yogic meditation involving chanting also reduced inflammatory gene expression, as well as stress levels, among individuals who care for patients with Alzheimer's disease.

"These studies begin to move us beyond simply connecting the mind and genome, and identify simple practices that an individual can harness to improve human health," Irwin said.

Other authors of the study include first author David Creswell, who led the study during his postdoctoral training at the Cousins Center and is now an assistant professor of psychology at Carnegie Mellon University, and Lisa J. Burklund, Matthew D. Lieberman, Jesusa M. G. Arevalo, Jeffrey Ma and Elizabeth C. Breen, all of UCLA. The authors report no conflict of interest.

The UCLA Cousins Center for Psychoneuroimmunology encompasses an interdisciplinary network of scientists working to advance the understanding of psychoneuroimmunology by linking basic and clinical research programs and by translating findings into clinical practice. The center is affiliated with the Semel Institute for Neuroscience and Human Behavior and the David Geffen School of Medicine at UCLA.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
