There is absolutely NO truth to the idea that most people are dehydrated. This is simply nonsense and there isn't a shred of evidence to support it. Similarly, there is no support for the idea that you "need" 8 glasses (or more) of water daily.
As previously suggested, you can drink when you're thirsty. Period. You'll be fine. There are WAY too many myths about the "need" to drink more, happily encouraged by the bottled water industry and the water bottle industry. You do NOT need to drink half your body weight in ounces, this is another frequently repeated myth. If you assess your water balance by observing your urine, you will find that it takes much less than 8 glasses a day to keep your urine pale yellow.

I got that conversion on water compare to coffee and tea from a dietian awhile ago. It further stated that over 50% of Americans are partly dehydrated at all times. I also read it in a doctor's magazine on digestion.

Everyone's body weight fluctuates on a daily basis. Sure, you can weigh in at quite a bit higher after drinking a lot of water. This will even itself out though. Try weighing yourself only 1st thing in the am after you've used the rest room. This should give you more accurate numbers. And while water could contribute to up to 5 lbs (which could mean a great deal to you when looking down at the scale) it's not all that significant when looked at as a percentage of you entire body weight.
I guess the point is, if you started this process slightly dehydrated and you went to being super hydrated, that might register in BADLY, but only once. If you continue your better level of hydration, then weigh ins after that will start to show a decrease again.
Good luck! Keep up the water and keep up the exercise. and TRY not to sweat the scale. Easier said than done I know!
lorne- i don't know where on earth you got that conversion ratio, but it's incorrect. your body will take the water out of soda, tea and coffee and use it, just like it would plain water. some of those have a slightly diuretic effect, but i wouldn't even consider 2oz to be a reasonable replacement amount [but i might give you 2 grams of water] for every cup of soda, tea and coffee.
i will also attest from many years drinking no water, soda exclusively with a tea here and there that doing so will not dehydrate you or kill you. and i was mostly living on doritos, pringles and pizza at the time so it's not like i was getting a lot of water from foods. your body will take what it needs and what it can get from whatever you give it.
I try to drink atleast 9 to 10 glasses of water each day due to health issues. I don't know how many people realize that for every cup of coffee, tea or soda a person drinks, you need to drink 2 cups of water to replace the lost water in your body caused from that drink. That is why I try to limit my caffeeine intake. I wouldn't want my body to need 14 cups of water to make up for the lost fluid.

You can drink water to the point of dying but it would be nearly impossible for a person of sound mind to do that. The only time I've heard about that happening is when the person involved was doing some serious drugs that tricked them into thinking they needed more and more and more water.
Avoid drugs and you'll be fine.
You won't retain water by drinking more water. You body retains water when there is too much sodium/not enough water in your system. More water means less water retention because it flushes out any excess sodium.

similar work conditions and workouts, I drink about 12 cups of water daily. You're fine.

I think you can overdo anything, even drinking water. I try to drink 10 eight ounce glasses a day.
I do indeed sit in an air conditioned office all day. I will check my urine color the next time I go, which is often. Thanks for the help.
I drink a bottle of water each time I work out. Should be enough to cover the sweat each time. Other than that, I drink a bottle at breakfast, lunch and dinner, and then one in between each...that is 7 per day. 16.9oz per bottle so around 118 oz per day. I weigh 215 lbs.
I also drink two cups of coffee a day.

I recently saw a nutritionist who declared that I need to be drinking at least 72oz of water a day. She said that is the LOW end for my weight and lifestyle. Before her, I was happy just drinking when I was thirsty, and I feel that forcing water down all day long is not beneficial. But I am the one who can't lose weight, so I am trying to put aside my opinion and follow her professional advice. I doubt our ancestors sat around by the river drinking water all day and peeing every 15 minutes. I think they probably drank when they were thirsty and our bodies are adapted to that. But what do I know? Now, back to my water bottle.....ugh.
I drink 1/2 my weight in ounces daily which is roughly 125oz a day. I also eat plenty of veggies and some fruit which add to the water. Prior to weigh in-- I don't drink anything, eat anything, go to the bathroom.
My doctor is not even sure that 125oz is enough. He says that most people are really dehydrated so even if you think you are drinking a lot of water, you may still be dehydrated.
yes, drinking water can kill you. but you have to be talking measuring your drinking in gallons per hour [which you aren't] and you need to be not urinating as well. there are certain medical conditions where you should be limiting your water consumption, but you'd already be under a doctor's care and advised of that if it were the case.
as far as how much you should be drinking, it's the amount you're putting out. in other words, if you live in a hot climate and you work out and sweat a lot, 8-10 bottles of water might be a reasonable amount. if you sit at an air conditioned desk and don't move all day, it might be way too much. if your urine is a pale yellow color, you're doing just fine. if your urine is clear, you can scale back how much water you're drinking.
