Add oxygen to speed sobriety

Written by Science Knowledge on 1:11 AM

BOOZE that has been treated so that you sober up faster afterwards may sound like a drinker's dream. But could end up being their down fall if it encourages heavy drinkers to consume even more alcohol. Kwang-il Kwon and his colleagues at Chungnam National University in Daejeon, South Korea, gave 30 men and 19 women 360 milliliters of a drink containing 19.5 per cent alcohol by volume, about the strength of fortified wine or sake. The drinks also contained 8, 20 or 25 parts per million of dissolved oxygen, which is known to play a role in alcohol breakdown by the body. It took about 5 hours for the blood alcohol levels of volunteers to reach zero. But Kwon's team found that on average, those whose drinks contained 20 or 25 ppm of oxygen went to zero 23 minutes and 27 minutes faster respectively than those who had the lowest-oxygen drinks (Alcoholism: Clinical &­Experimental Research, DOl: 10.lll1/j.1530-0277.2010.01155.x).

The researchers suggest that enriching alcoholic drinks with oxygen might "allow individuals to become sober faster". 'The reduced time to a lower blood-alcohol concentration may reduce alcohol• related accidents," they write. A spokeswoman for the British Medical Association was unimpressed. "We would n't want a situation where people drank more simply because they would recover quicker."

About Me

In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being experimented for its validity by other researchers working under the same conditions.
