......[align=center]Too much drinking puts runners in hot water

[align=center]Marathon runners are in danger of drinking themselves to death.[/align]

Many runners wrongly believe dehydration is the greatest threat to their health, but according to US researchers, too much water can be as dangerous as too little in long-distance events.
Doctors from the Harvard School of Medicine took blood samples from 488 runners in the 2002 Boston marathon, before and after the race, and found 13 per cent had diluted the salt levels in their blood to dangerous levels. This condition, called hyponatremia, can lead to coma and even death.
One 28-year-old runner who collapsed during the 2002 race and later died was found to have severely low levels of salt in her blood. Three other Boston runners had salt levels so low they risked death.
Slower runners were at the greatest risk of the problem, because they stopped more often for drink breaks. Many gained weight during the the race because they drank so much.
The problem of over-drinking has long been recognised by sports doctors, but this study, published yesterday in The New England Journal of Medicine, is believed to be the first documentation of its seriousness.
Dr Carolyn Broderick, the director of the sports medicine program at the University of NSW, said next to heat exhaustion, hyponatremia was the biggest cause of runners collapsing. "Most people are mindful of it if they are used to looking after marathon events," she said. "But average people are probably not aware of it. We are always encouraging people to drink more."
Dr Dick Telford, an exercise physiologist at the Commonwealth Institute at Cambridge University, said hyponatremia was common among less experienced runners, especially during marathons in cool weather, when dehydration was not a threat.
Runners already secreted water into the bloodstream through aerobic exercise and through the breaking down of glucose in the blood, he said.
"If you are running along, you are getting unexpected sources of water anyway, then when you take in a lot of water on top of that, you can get very sick."
