A 14 years old has surprised the city scientists with her discovery of the impact of the 'Om' sound in reducing fatigue. Anwesha Roy Chowdhury, a student of Class-IX  in Adamas World School, had topped in the recently held Science Congress, organized by the state government.

She found that chanting of 'Om' increases oxygen level in blood and lowers the carbon dioxide and lactic acid, which helps in reducing the level of fatigue, that had been evaluated critically by physics and physiology professors of Calcutta University and Jadavpur University. Debashish Bandopadhyay, head of the department of physiology, Calcutta University, said that "Anwesha's project is innovative, it's quite flawless and convincing."

An-we-sha, likes to spell her name because in bengali, anweshan means 'search'. She told The Times Of India, "I found that sounds with a particular frequency, if heard or recited right, raises the level of neurotransmitters and hormones like serotonin, dopamine, DHEA etc. Because of their vasodilatory actions, the oxygen level in blood soars. It also produces less lactic acid and allows the person to act without fatigue."

Rina Venkataraman, secretary of the state science and technology department said, "In the last decade, the body of research on workout music had swelled considerably, helping psychologists refine their ideas about why exercise and music are such an effective pairing. But this specific finding on the 'Om' sound is impressive”.

Dipankar Das, senior scientist, state science and technology department, stated during a workshop conducted on 165 students who had been shortlisted for the statewide Science Congress recently, "No one has ever pin-pointed on the 'Om' sound and conducted such comprehensive experiments on its use,"

These all had started when Anwesha visited Uttarakhand, where she had found some priests carrying water from Bageshwar to Kedarnath, covering 68km every day, without any tiredness. The priests had been singing a tune all along. There was no way that she could reproduce the same mantra for her experiments. So Anwesha started looking for a similar tune.

Anwesha said, "Finally, a tune with 430+ Hz frequency clicked. In five experiments in various laboratories, I measured the oxygen and carbon dioxide levels of 17 adults (all on the staff of BITM) while listening to the tune for 30 minutes, and there was an increase of oxygen level and decrease in carbon dioxide in their bodies” .
