Research has found that singing helps to boost the immune system, especially in a group setting.
Researchers found that the concentration of proteins in the immune system and an anti-stress hormone increased during singing by a choir. They compared these results with the same choir that only listened to the same song. The concentration of proteins did not rise as drastically.
Posture
Singing has been found to help with posture, the toning of the abdominal muscles, and increases lung capacity. Research has also found that singing helps to clear the sinuses and respiratory tubes. Because singing is an aerobic activity, it also has been found to stimulate circulation. It 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.
Aids Mental Ability
Research is being done on the effect that singing has on concentration, alertness and memory, visual and listening skills. Singing has been found to lessen stress and has been found to help with better and more restful sleep. Recent studies have found that singing that the sacculus ( found in the inner ear) which is connected to the part of the brain responsible for registering pleasure responds to frequencies found in music. The sacculus responds quickly to the low-frequency, high-intensity sounds connected to singing which means you can get immediate pleasure from singing.
Immune System
Science has been studying the effect of singing on the recovery of the body. Studies are suggesting that singing may help people recover from such things as strokes and heart attacks. Singing is known to release endorphins which help to relieve pain. A recent study in the Journal of Music Therapy has suggested that singing has the ability to cope better with chronic pain.
