Our adult human bodies are comprised of (at least) 50% - 60 % water. [*Dr. Jeffrey Utz, Neuroscience, pediatrics, Allegheny University*]. In the cold weather it is easy to trick ourselves into hydrating less because we just don’t feel as thirsty as we do when it is hot out. But do. Hydrate. Drink water, any temperature of water.
**PS. Wine does not count as hydrating more, just saying.
Electrolytes are electrically charged positive or negative ions that maintain nerve and muscle functions, maintain fluid balance and regulate body pH -- or acid-alkaline balance. To conduct normal biochemical functions your body needs the minerals calcium, potassium, sodium and magnesium, which also serve a dual role as electrolytes.
They conduct themselves in water.
If you catch a cold or flu and you lose fluids through sweat (and the other usual culprits), you lose electrolytes as well and, if you have an iffy diet, you may lack electrolytes to begin with.
The best way to build and maintain your electrolytes is through a well-rounded diet. The fastest way to replenish your electrolytes is with supplements. Preferably do both. There are electrolyte drinks on the market. Decide what works best for you, though I suggest you stay away from the ones that are fake any-colour and that you read the ingredients carefully before consuming.
Whichever way you do it, do it. Take care of you. Did we mention hydrate?
