Here we go again. A few weeks ago I wrote a post on how a new study revealed that taking too much Vitamin E can actually hurt more than help you, as had been reported over the past 15 years or so.
Now it turns out, supposedly, that drinking too much water or sports drinks when running or working out in hot weather is actually detrimental to your health, causing death among long-distance runners in some cases.
A study just released in the New England Journal of Medicine found that a marathon runner, for example, could seriously dilute the blood with an overdose of liquids, resulting in a coma or death.
Because we’ve been taught for so many years to give water or a sports drink when it appears someone is suffering from heat stroke (after a long summer hike, for example), we actually could be giving them the poison to kill them.
Or so this study says, anyway. In 20 years’ time there will be another study that says thousands of people have died because they didn’t get enough water due to their fear of being over hydrated, based on this new study.
It seems to me the best remedy is: drink when you’re thirsty. Eat when you’re hungry. Avoid anything chemically manufactured unless there’s no choice.
But, then, I’m not a doctor…or a researcher…or better yet, one who funds these kinds of studies (and their built-in biases).
So now I’m confused, when I go on a long hike in the canyon this hot weekend, should I drink lots of water, or should I fight the urge to drink?
OK, I get it. Soon there will be a major marketing campaign undertaken by the companies that make instant tests that you can take while hiking or running where one can instantly determine their sodium levels to see if they need more or less water in their system.
Now I’m beginning to wonder who funded this study?
