It is important to a healthy lifestyle to drink enough water. There are many recommendations out there about how much water we are supposed to consume. The Dietitians of Canada recommend a fluid intake of 3 L (12 cups) per day for men over 19 years old and 2.2 L (9 cups) for women over 19 years old. Fluid intake refers to just that: fluid. Water, coffee, juice, soda, and tea: they all count.
I am terrible for remembering to drink water. I usually have a cup of coffee or tea for breakfast. Once my day gets going, my fluid intake gets put on the back-burner. I usually realize sometime around lunch time that I am super thirsty. I then chug as much as I can, which isn't always helpful.
I am making a commitment to drink 8 cups of water every day in addition to my morning cup of coffee. I have been using a large plastic (BPA-free, of course) tumbler cup or a large water bottle to track my water intake. I know that I need to drink 2 of the tumblers and 2.5 water bottles in order to meet my quota. I keep it near me so that when I see it, I remember to take a sip. It has actually been working really well!
*NOTE* It is dangerous to consume too much fluid, so you should always trust your body. If you are not thirsty, you shouldn't force any more fluid into your body. Sticking near the 9 cups per day can help make sure you don't overdo it.
