15 glasses of water?!

I DRINK Like 1.5 gallons of water everyday.. AS WATER DOESN'T HURT UNLESS YOU ARE DRINKING MORE THAN 1-2 GALLONS A DAY. WATER SHOULD BE DRUNK THROUGH OUT THE DAY.

1.5 gallons (6 liters) total is coincidentally what killed Cynthia Luceros. A post-mortem showed she would have died sooner if she had sat more that day (she ran 20 miles), had drank pure water instead of sports drinks, or drank it more quickly than over the course of several hours. Thus, the above statement is false. If you're going to drink in excess, it's worth learning more about the limits of the human body to avoid catastrophe, or alternatively simply drinking in moderation for peak health and performance.

What kills you about drinking water is diluting out the sodium in your blood so low that your salinity drops to a fatal level (your cells start lysing). This can happen by either drinking too much water or by depleting your sodium without replacing it. Its a balance.

If your body has plenty of sodium drinking that much isn't going to harm you. Whether it serves an actual purpose to drink that much is questionable though.

What killed that woman based on your description was she was probably low sodium, went for a 20 min run where she sweat bullets and depleted her sodium even more then drank a ton of water diluting out what little sodium she had left to a point where it was fatal.

one of the biggest things is , all liquid is part of that "water" goal , coffee tea, all of it , and an 8 oz glass of water is not much most home glasses of water are 16+ oz , mine is 24 , so in reality its only 3 "glasses" a day, if i went that low i would feel dried out like a prune ...
just saying ..

its easier than people think.

Yeah when people say 8 "glasses" of water or 15 "glasses" of water they are using the term glass to mean one cup or 8oz however almost any actual physical glass is going to hold much more than that. So if you think 15 cups and equate that to 15 glasses then picture your glass at home which actually holds 20oz of liquid then yeah it sounds like a lot then.

Well said.

Per the detailed account I have, her sodium levels actually began at 140 mmol/L (normal), she ran lightly for five hours at about 4.25mph on a cool day sweating very little, and drank 1.2L of gatorade per hour. Drinking Gatorade instead of water--which has some sodium in it--is credited with allowing her to survive 5 hours instead of 4 hours. Don't give them too much credit, though! She we actually following their hydration guidelines when she died, and better for her health and performance was clearly drinking less.

Agreed, a high-sodium diet is a good companion to high water intake, and brings it into a safer range. This is what I do when I must drink excessive quantities of water (multi-hour endurance events). Long-term, you may dilute other nutrients, and it's questionable high-sodium w/ water retention is best for you.
