I have a link and PDF file for analysis, 6-7 sentences for each of them, so around 150 words in total should be the maximum word count, I’m fine with less.

Ask Well: Can You Drink Too Much Water?
By Gretchen Reynolds June 19, 2015 5:45 am

Q

Is it possible to drink too much water?
I typically drink far more than the recommended six to eight glasses per day, and feel
dehydrated if I adhere to the guidelines. I have no underlying medical conditions, such
as diabetes, that would lead to increased thirst.

Absolutely, and if you do, you can develop a dangerous condition
called hyponatremia, or water intoxication.

Under normal conditions, the body beautifully maintains its fluid balance. Lose
fluids through sweating, for instance, and your body responds with the feeling of
thirst. You drink. If you swallow more liquid than needed just then, your body
typically responds by excreting the excess through urination.

But should you consume so much fluid that your body can’t easily rid itself of
the surplus, you dilute sodium levels in your blood. Osmosis then draws water from
the blood into body cells to equalize sodium levels, and those cells swell. At that
point, you have hyponatremia. If the cellular bloating occurs in the brain, it can be
fatal.

Until about 20 years ago, hyponatremia was extremely uncommon among
healthy people. But then several marathon runners died from hyponatremia. In
general, they had been middle- or back-of-the-pack, slower runners. They did not
sweat much. But they drank plenty of water, trying to ensure that they would be well
hydrated.

Today, most knowledgeable coaches and exercise experts warn athletes not to
overdrink. “You should drink only when you need to, when you are actually thirsty,”
said Dr.  James Winger, a professor of family medicine at Loyola University Medical
Center, who has studied the hydration habits of athletes.

If you’re not sure whether you’re drinking too much or too little during exercise,
try weighing yourself before and after a lengthy workout, experts advise. If you have
lost more than about 3 or 4 percent of your body weight, you’re probably flirting with
dehydration and might want to drink a bit more next time. But if you have gained
weight or your fingers seem swollen and your rings tight, you’re most likely drinking
too much and should moderate intake.

Most important, listen to your body’s signals, Dr. Winger said. “Thirst is a very
reliable indicator,” he said, of whether and how much to drink.
