ORLANDO, Fla. (Ivanhoe Newswire) -- Water is the most important thing you put in your body. Experts say humans can go up to two months without food, but would die after seven days without fluid.
It's essential for survival, but do you really need eight cups of water every day?
The Institute of Medicine recommends that women should drink about eight daily cups and men should drink about 12 cups of any fluid, not just water.
Can drinking water help you lose weight?
Water can replace other high-calorie beverages and help you feel fuller. A German study also found participants increased their metabolic rates by 30 percent after drinking about 17 ounces of water.
Does dark urine mean you're not getting enough water?
Not necessarily. Foods like blackberries, beets and asparagus can be the culprits.
What about drinking extra water to prevent wrinkles?
There's no evidence that H2O can improve skin in people who are well hydrated. Try a moisturizer instead.
Another popular myth is that if you're thirsty, you're already dehydrated. If you start to feel thirsty, you should drink, but it doesn't necessarily mean you're dehydrated.
