Medical News: Exercise and Alcohol Effect on Health

Prticipation in sport is associated with a with a 20—40% reduction in all-cause mortality compared with non-participation. Exercise might also be considered as a fifth vital sign, according to the Lancet: http://goo.gl/gyxYf

Exercise or have a drink? It may be better to exercise AND have a drink

A study of 12,000 people over a 20-year period in Denmark found that exercise and drinking alcohol each had an independent beneficial effect on the heart. The effect was even greater when the two were practiced together. According to TIME magazine:

"People who don't drink at all and don't exercise had the highest risk of heart disease. People who drink moderately and exercise had a 50% lower risk. Teetotaling exercisers had a 30% decreased risk, as did moderately drinking couch potatoes. "There's an additional protective effect to doing both," says Gronbaek. "That's the new finding."

Weekly alcohol intake was inversely associated with fatal ischemic heart disease and had a U-shaped association with all-cause mortality.

Exercise slows telomere shortening (and aging)

Telomeres are the chromosome tips which shorten each time a cell divides, making them a possible marker of aging. A study of 2400 twins showed that physically active people had longer telomeres than sedentary people. According to the authors, this provides a powerful message that could be used by clinicians to promote the potentially antiaging effect of regular exercise.

  1. Same old story: people that don't exercise and don't drink might have some health problem thus introducing bias.

  2. As a physician, would you ever advise a non alcoholic to start drinking?

    Wouldn't that be too risky?

    What if in the next couple of years they find some beneficial effects for nicotine, would we start encouraging people to smoke a cigarette a day?!
