(also since we're on the topic of hydration haha -- pulling out some stuff I learned in uni)For normal people doing normal work outs, water is generally enough to keep you hydrated and you don't need the extra salts from sports drinks like gatorade to re-hydrate and replenish your electrolytes. It's only when your body is lacking in electrolytes that water is not enough. This occurs when one is:
1) Serious athlete - doing lots of strenuous activity like sports, training/running a marathon2) Exercising in really hot/humid conditions --> lots & lots of sweating3) Not getting enough electrolytes and important minerals through your diet byeating lots of vegetables --> electrolyte deficiency symptoms felt throughout the dayThe Electrolytes: Sodium, Calcium, Potassium, MagnesiumIn particular, sodium is very important for maintaining the electrolyte balance in the body. It's all about maintaining a healthy balance of sodium (and other electrolytes) to water in your body. You can do so by drinking enough liquids (water, green coconut water) throughout the day and making sure that food rich in electrolytes are regular fixtures in your daily diet.
You don't need to be consuming gatorade and other sports drinks every day just to get your electrolyte fix (unless you're doing lots of sports/strenuous activity). It would be better to add/fix foods naturally containing electrolytes such as dairy (calcium), potatoes (calcium, magnesium), spinach (calcium, magnesium), or bananas/sweet potato/squash (potassium) to your regular diet.
For cases when electrolytes are lost through a fever, vomiting, or diarrhea, you can make this healthier
Oral Re-hydration Solution at home --> also contains less sugar than your average 20 ounce serving of gatorade if you want to watch your sugar intake.
TL;DR - For the normal lay person doing regular workouts (i.e. not an athlete), eating a diet rich in minerals will keep your body's electrolyte balance happy; you don't really need that bottle of gatorade.***Also, beware of drinking too much water as that also upsets the body's electrolyte balance. Chugging down too much water in a short amount of time can lead to what's called "water intoxication."
