How much water am I supposed to drink in a day? I've heard 8 glasses, 6 glasses, 10 glasses - but how do I know what's right for my own body?
Take the pee test. Sounds classy, I know. But it can be quite informative.
After you pee in the toilet, take a look. Really. I'm serious. What color do you see? Is it dark yellow, light yellow, or does it look clear?
The color of pee is caused by bile, the chemical your liver produces to break up fat. When our bodies break down bile, the pigment urochrome turns pee yellow. The lighter the color, the more it's watered down.
Here's the deal. If you are drinking enough water for your body, your urine will be as clear as water. If your pee is - then you passed the test.
Also, your water needs can change from day to day, so monitor it by checking your pee. If it's clear, you're all good. You can also check out Fit's Calculator to see how much water you should be drinking daily.
