You need water to exercise—you thrive on it—yet so many of us spend their days dehydrated. It could be because, when it comes down to it, you may not even know exactly when you’re dehydrated. Here are some signs that show you that you need to get way more H20 happy
Unless you’re chugging water 24/7, your body is constantly losing fluid. That means you’re also losing essential salts like sodium and potassium because those are in the fluids you’re losing. Now get this: That salt loss actually changes the chemical makeup of your blood. Your brain, in turn, is super sensitive to that change—and it’s that sensitivity that triggers a headache. Make sense? The headaches get even worse, too, depending on how much water you lose. The more water you lose, the more your blood volume drops, which causes less oxygen flow to the brain, That causes your blood vessels to dilate, which can make your headache feel even worse. Moral of the story: Not enough water equals headache central.
The reason why our Urine has a dark yellowish colour is that your urine is over-concentrated with waste. When you’re fully hydrated, the waste is easily flushed out in a more efficient manner. But when there aren’t enough fluids in your body, the waste isn’t as easily flushed out, so it stays there.
Somewhat similar to our previous point; water helps move your waste through your colon and out of your body. But if that water isn’t there to begin with, it won’t be able to move your food waste onward and outward as efficiently. Hence the constipation.
