Whether it's an a cappella group or the church chorale, a small new study shows that singing in a choir could do a lot for your state of mind.

The findings, published in the journal Psychology of Music and conducted by researchers at Abant Izzet Baysal University in Turkey, show that singing in a choir is associated with decreased levels of anxiety.

The study included 35 people who were assigned to either one hour of choir singing, or one hour of "unstructured time" (the control group). Researchers analyzed their positive and negative affect, as well as their levels of anxiety and salivary amylase (amylase is an enzyme that is often used as a marker for inflammation).

Researchers found that the participants assigned to sing in the choir had decreases in their negative affect and anxiety, compared with the control group. Meanwhile, the control group experienced more anxiety and negative affect before and after the hour period.

The benefits of joining a choir could go beyond mental health, too. Norwegian researchers previously reported that participation in a choir is linked with better health and workplace engagement, ScienceNordic reported.

"The health benefits of singing are both physical and psychological," Graham Welch, chair of music education at the Institute of Education at the University of London, said in a Heart Research UK statement. The benefits of singing range from the physical -- because it boosts oxygen levels in the blood -- to the psychological -- because it lowers stress and boosts feelings of community, he said.

  • Eases Anxiety In Cancer Patients

    Researchers from Drexel University found that cancer patients who either listened to music or worked with a music therapist experienced a <a href="http://news.health.com/2011/08/12/music-eases-cancer-patients-anxiety-study/" target="_hplink">reduction in anxiety</a>. The review by the Cochrane Collaboration included 1,891 people with cancer, and found that people who participated in music somehow not only had decreased anxiety, but also <a href="http://news.health.com/2011/08/12/music-eases-cancer-patients-anxiety-study/" target="_hplink">better blood pressure levels</a> and improved moods, HealthDay reported.

  • Reduces Stress

    If you listen to your iPod every day on your way to work or break out the guitar every evening, then you'll like this finding. A doctoral thesis from the University of Gothenburg reveals that <a href="http://www.samfak.gu.se/Faculty+of+Social+science/News/News/News_Detail//everyday-music-listening-reduces-stress.cid1066914" target="_hplink">listening to music every day</a> lowers stress. The thesis was based on the results of two studies, which showed that people who listened to music also felt positive emotions. "But it should be pointed out that when studying emotional responses to music it is important to remember that all people do not respond in the exact same way to a piece of music and that one individual can respond differently to the same piece of music at different times, depending on both individual and situational factors," thesis author Marie Helsing said <a href="http://www.samfak.gu.se/Faculty+of+Social+science/News/News/News_Detail//everyday-music-listening-reduces-stress.cid1066914" target="_hplink">in a statement</a>. "To get the positive effects of music, you have to listen to music that you like."

  • Helps During Surgery

    Listening to music while lying on the operating table could help to <a href="http://www.time.com/time/health/article/0,8599,1929994,00.html" target="_hplink">lower stress</a>, <em>TIME</em> reported. The research, conducted by Cleveland Clinic researchers, included patients -- mostly with Parkinson's disease -- as they were undergoing brain surgery. The researchers found that the study participants who listened to <a href="http://www.time.com/time/health/article/0,8599,1929994,00.html" target="_hplink">pure melodies</a> -- versus just rhythmic arrangements, or a mix of the two -- were comforted the most. Their brains also reflected this calming, <em>TIME</em> reported, with some of the study participants even falling asleep.

  • Protects Your Ears' Sound-Processing Abilities

    A 2011 study in the journal <em>Psychology and Aging</em> shows that being a lifelong musician is linked with <a href="http://www.washingtonpost.com/national/health-science/quick-study-lifelong-music-training-may-help-stave-off-hearing-loss/2011/09/28/gIQA0JI4IL_story.html" target="_hplink">better sound processing</a>, the <em>Washington Post</em> reported. The study included 163 people (74 of whom had played music all their lives). The researchers also found a link between hearing test scores and the amount of time the study participants practiced their music, according to <a href="http://www.washingtonpost.com/national/health-science/quick-study-lifelong-music-training-may-help-stave-off-hearing-loss/2011/09/28/gIQA0JI4IL_story.html" target="_hplink">the <em>Washington Post</em></a>.

  • Boosts Heart Health

    Odd as it may seem, University of Maryland Medical Center researchers have found a link between listening to music and heart health. The researchers found that listening to joyful music is linked with <a href="http://www.umm.edu/news/releases/music-cardiovascular.htm" target="_hplink">dilation of blood vessels' inner lining</a>, meaning more flow of blood through the blood vessels. Specifically, the diameter of blood vessels grew by 26 percent when a person listened to happy music. However, the opposite effect was noted when a person listened to anxiety-triggering music -- blood vessel diameter <em>decreased</em> by 6 percent as a result. The research was presented in 2008 at a meeting of the American Heart Association.

  • Soothes Pain

    Researchers from University of Utah Pain Research Center showed that listening to music is effective as a distraction for anxiety-prone people <a href="http://healthcare.utah.edu/publicaffairs/news/current/01-06-2012_Study_Pain_Relief.html" target="_hplink">from feeling pain</a>, and as a result, could help people feel less pain. The study, which included 143 people, was published in the <em>Journal of Pain</em>. The researchers found that music helped the study participants to have less arousal when shocked with non-dangerous fingertip electrodes.

  • Helps Memory

    Kids <a href="http://www.webmd.com/baby/news/20030728/music-lessons-verbal-memory" target="_hplink">who take music lessons</a> could be doing their brains a favor, according to Hong Kong researchers. WebMD reported that taking music lessons is linked with doing better on tests where you have to recall words you read on a list. And "the more music training during childhood, the better the verbal memory," study researcher Agnes S. Chan, PhD, a psychologist at the Chinese University of Hong Kong, <a href="http://www.webmd.com/baby/news/20030728/music-lessons-verbal-memory" target="_hplink">told WebMD</a>. "This strongly implies that the better verbal memory in children with music training is not simply a matter of differences in age, education level, or their family's socioeconomic characteristics."

  • Protects The Aging Brain

    Having musical training could <a href="http://health.usnews.com/health-news/family-health/brain-and-behavior/articles/2011/04/25/music-training-may-help-keep-aging-brain-healthy" target="_hplink">protect your mental sharpness</a> in old age, according to a 2011 study in the journal <em>Neuropsychology</em>. HealthDay reported on the study of 70 people ages 60 to 83, with varying levels of music experience. The researchers from the University of Kansas Medical Center found that the people who had the <a href="http://health.usnews.com/health-news/family-health/brain-and-behavior/articles/2011/04/25/music-training-may-help-keep-aging-brain-healthy" target="_hplink">most musical training</a> in their lives had the best mental sharpness, and scored the highest on brain functioning tests.

  • Prevents Heart Transplant Rejection (In Mice)

    It may so far only be shown in mice, but it's still pretty amazing: Japanese researchers found that exposing mice to certain kinds of music was linked with "prolonged survival" after a <a href="http://www.miller-mccune.com/health/classical-music-boosts-heart-transplant-survival-in-mice-40561/" target="_hplink">heart transplant</a>, Miller-McCune reported. The mice in the study were exposed to either Mozart, Verdi (opera music), New Age-type music, no music at all, or a sound frequency. Mice who listened to Mozart and Verdi had a <a href="http://www.miller-mccune.com/health/classical-music-boosts-heart-transplant-survival-in-mice-40561/" target="_hplink">longer survival time</a> after the heart transplant, compared to the other mice, according to Miller-McCune.

  • Improves Stroke Recovery

    Finnish researchers found that listening to music soon after a stroke could <a href="http://www.news-medical.net/news/2008/02/20/35390.aspx" target="_hplink">help with recovery</a>, News Medical reported. Published in 2008 in the journal <em>Brain</em>, researchers found that <a href="http://www.news-medical.net/news/2008/02/20/35390.aspx" target="_hplink">listening to music</a> was linked with improved verbal memory and attention among stroke patients, compared with listening to audio books or not listening to anything at all.

  • Works As Well As A Massage At Lowering Anxiety

    Massages are super-relaxing, sure -- but a study in the journal <em>Depression and Anxiety</em> shows that music could also do the trick, at least when it comes to <a href="http://health.usnews.com/health-news/family-health/brain-and-behavior/articles/2010/03/19/music-soothes-anxiety-as-well-as-massage-does" target="_hplink">decreasing anxiety</a>. Researchers from the Group Health Research Institute found that patients who got 10 hour-long massages had the same <a href="http://health.usnews.com/health-news/family-health/brain-and-behavior/articles/2010/03/19/music-soothes-anxiety-as-well-as-massage-does" target="_hplink">decreased anxiety symptoms</a> three months later as people who simply listened to music (and went sans-massage), HealthDay reported. The study included 68 people who received the 10 massages with music, laid down while listening to music (but didn't get a massage), or were wrapped with warm pads and towels while listening to music (but didn't get a massage), according to HealthDay.
