At this point you've probably heard of electrolytes, but do you know what they are and why they are important? Electrolytes are the key minerals that allow our cells to absorb water - think of them as the sponges that soak the water in. When our electrolytes are low, no matter how much water we drink we remain dehydrated.
What types of minerals are electrolytes? Sodium, calcium, potassium and magnesium in specific forms and in specific ratios. Do you regularly crave salty foods? Chips, pretzels, popcorn? Can't get enough salt on your food? Yup, your body is talking to you! It's letting you know that your electrolytes are low and you are getting dehydrated.
We lose electrolytes in 2 ways - urination and perspiration. That's why (sometimes) if you're drinking a lot of water, no matter how much you drink you are still thirsty and have "cotton mouth". That's why when you finish a workout, you think you're starving and need to eat.
