Scientists say singing boosts immune system
Singing strengthens the immune system, according to research by scientists at the University of Frankfurt in Germany, published in the latest edition of the US Journal of Behavioral Medicine. The scientists tested the blood of people who sang in a professional choir in the city, before and after a 60 minute rehearsal of Mozart's Requiem. They found that concentrations of immunoglobin A - proteins in the immune system which function as antibodies - and hydrocortisone, an anti-stress hormone, increased significantly during the rehearsal. A week later, when they asked members of the choir to listen to a recording of the Requiem without singing, they found the composition of their blood did not change significantly. The researchers, who included Hans Guenther Bastian from the Institute of Musical Education at Frankfurt University, concluded singing not only strengthened the immune system but also notably improved the performer's mood.
Singing is good for you
Many studies done over a number of years have focused on the health benefits of singing, and the evidence is overwhelming.
• Singing releases endorphins into your system and makes you feel energized and uplifted. People who sing are healthier than people who don’t.
• Singing gives the lungs a workout.
• Singing tones abdominal and intercostal muscles and the diaphragm, and stimulates circulation.
• Singing makes us breathe more deeply than many forms of strenuous exercise, so we take in more oxygen, improve aerobic capacity and experience a release of muscle tension as well.
Singing can help prolong life
Graham Welch, director for advanced music education at London’s Roehampton Institute, states “Singing exercises the vocal cords and keeps them youthful, even in old age. The less age-battered your voice sounds, the more you will feel, and seem, younger.” He says that when you break into song, your chest expands and your back and shoulders straighten, thus improving your posture. Singing lifts moods and clears the “blues” by taking your mind off the stresses of the day, as well as releasing pain-relieving endorphins. As you sing along, the professor adds, your circulation is improved, which in turn oxygenates the cells and boosts the body’s immune system to ward off minor infections. And “it provides some aerobic exercise for the elderly or disabled,” Welch says. A recent German study has shown that active amateur group singing can lead to significant increases in the production of a protein considered as the first line of defense against respiratory infections, and also leads to positive emotional changes. “Given that every human being is, in principle, capable of developing sufficient vocal skills to participate in a chorale for a lifetime, active group singing may be a risk-free, economic, easily accessible, and yet powerful road to enhanced physiological and psychological well-being.”
