Subject: OFF в мире науки, или очевидное-невероятное http://www.ananova.com/news/story/sm_1658012.html?menu=Hangover remedies 'don't work'
The only way to avoid a hangover at Christmas is to stay sober.
Researchers who examined eight trials of traditional hangover remedies found there was no clear proof any worked.
Researchers said: "No compelling evidence exists to suggest that any conventional or complementary intervention is effective for preventing or treating alcohol hangover.
"The most effective way to avoid the symptoms of alcohol-induced hangover is to practise abstinence or moderation."
Dr Max Pittler, from Exeter's Peninsular Medical School, led the research and said hangovers accounted for about £2bn in lost wages each year in the UK, mostly due to sickness absence.
Hangover symptoms included impaired memory and visual-spatial skills, light-headedness, nausea, and lack of concentration.
Even consuming less than the recommended alcohol limits substantially increased the risk of dying, said the researchers.
At Christmas, higher alcohol consumption led to a 0.4% increase in fatal poisonings for every 1% increase in sales of spirits.
Hangover symptoms seemed to be caused by the main breakdown product of ethanol and acetaldehyde, hormonal and immune system disturbances, dehydration and sleep disruption.
Remedies listed on the internet included aspirin, paracetamol, bananas, cabbage, charcoal tablets, eggs, exercise, green tea, milkshakes, Vegemite on toast, pizzas, and 'hair of the dog' alcoholic drinks.
