Did you know you have a 20% higher chance of sustaining an injury during exercise when you are dehydrated?
A better gage for daily water requirements is to drink half your body weight in ounces of water. More if you exercise. (not all at once).
I found a great website to calculate your exact water needs, it factors in your climate, exercise times, and other factors to give you a daily water intake goal. To find out how much you should be drinking click Here.
I love these 24 oz. Contigo autoseal BPA free water bottles. I strive to drink at least three of these water bottles every day, four when I do a hard workout. I carry one of these pretty much wherever I go and sip water throughout the day. I bought the three pack at Costco several years ago for under $20. They are easy to use (just squeeze the top around the neck), they never leak, I can measure how much water I drink, the kids love them, they're hard to break (we have managed to crack them on the tile floor). I can't find them on the Costco website, but I just bought another 3 pack right before Christmas, so I think they still have them?
As always, consult with your doctor if you have a preexisting health condition. If you aren't a huge water drinker, it's a little difficult at first to adjust to this much water intake. You might want to start on a day when you have easy bathroom access. Don't worry your body will adjust quickly.
