Remember to drink plenty of fluids but be careful because if you hydrate too much, you may have an electrolyte imbalance, meaning:

"An electrolyte imbalance means that the level of one or more electrolytes in your body is too low or too high. It can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some of the more common reasons why you might have an imbalance of the water in your body include:

Certain medicines
Severe vomiting and/or diarrhea
Heavy sweating
Heart, liver or kidney problems
Not drinking enough fluids, especially when doing intense exercise or when the weather is very hot
Drinking too much water"
