Abstract
A good song can boost our mood while we are in pain through body or mind. Pain in body or mind is important, but pain in society is similarly important. Scientists have also found that music have a direct and measurable effect on acute pain. Folk music has come to occupy the lives of Bangladeshi people almost more than any other genre of Bengali music. Baul, Bhatiali, Bhawaiya, Dhamail, Gazir Gaan, Gombhira, alkap, Jhumur, Kirtan, Kavigan, Pala Gan, jari, Sari, Ghatu, Madar gan etc are the most famous folk music of Bangladesh. When we are in sorrow, we listen music in addition to decrease feelings of pain and we feel less pain and fewer negative effects of stress. Our folk music can help relieve chronic pain, can help to Control from Pain in personal and social life also. Our folk music is performing as social therapy to Pain Relief. It is scientifically proved that Soothing music can help relieve nagging pain. To relief from pains our body releases chemicals called endorphins. These endorphins interact with the receptors in our brain that reduce our perception of pain.
Stress and pain are the two most common factors leading to the release of endorphins. Endorphins interact with the opiate receptors in the brain to reduce our perception of pain and act similarly to drugs such as morphine and codeine. When we listen to music, the brain is constantly trying to predict the musical structure based on universal, cultural and individual musical rules. This article focuses the role of folk music in Bangladesh as the modulator to feel relief from pain. This article wills to prove that how the enjoyable folk music can trigger the release of opioids in the brain? Opioids are the body’s own ‘morphine’, which may explain why music can reduce the feeling of pain and the reduced need for pain medication. Our folk song could be the pain-relieving effect, however the result of music simply being an incredibly effective way of redirecting our attention away from our pain. Today the scientists have examined whether music can also have a positive effect on chronic pain in patients who suffer from fibromyalgia, a disease that causes severe chronic pain in the muscles and joints. Also, the Folk music of Bangladesh acting the role of modulator to reduce the social pain and making a non communal Bangladesh.
