Is There Such Thing as Drinking Too Much Water?
When exercising, you've got to watch out for dehydration caused by the combination of excessive sweating and not drinking enough water. To avoid the dizziness, headaches, and dry throat associated with this condition, you probably load up on water while working out, but you don't want to overdo it.
There is such a thing as drinking an excess of water.
Don't Drink Too Much Water When Running
It is important to keep hydrated when running a marathon but did you know that too much water can be a bad thing?
A good rule of thumb is to drink about one cup of fluid every 20 minutes during a marathon, anything more than that could be dangerous and could cause hyponatremia — when you have low amounts of sodium in your body. It can be fatal if not treated immediately.
The Skinny On: Sports Drinks
Staying hydrated when exercising in hot, humid weather is really important. However, if you are exercising, at a moderate level, for longer than an hour you should probably reach for a sports drink.
Unlike water, sports drinks contain electrolytes and carbohydrates to help your body absorb and retain fluid lost during exercise.
What's the Deal With: Hyponatremia
While it seems like most of us have a hard time staying hydrated, there are serious, even fatal, side affects to drinking too much water. The condition is called hyponatremia
Also known as water intoxication, hyponatremia occurs when the sodium in your blood is diluted by excess water. The body's balance of electrolytes is pushed outside of safe limits, disrupting normal brain function.

You Asked: Too Many Trips to the Ladies Room?
Dear Fit,
I drink tons of water, and probably go through four 32-ounce Nalgene bottles within the eight hours I am at the office, so I assume that's the reason. I'm wondering if this is bad for me? I go to the "ladies" at least once an hour to pee, and the guys in my office think it's way too often.

You Asked: Drinking Water While Running
A while back I wrote a post about the Nathan Speed 4 Water Holder. I thought this nifty gadget was great for long-distance runners, since it holds a total of 40 ounces of water. After reading the post, a user had a great comment.
