Typically, it’s not hard to get enough electrolytes from our food, but when we’re sweating a lot during activity-particularly in hot weather, for longer than an hour-we can lose more than we’re taking in.
Electrolytes are particles that conduct electricity in water, and they’re vital for normal human body function. If running in the summer leaves you feeling drained and depleted for the rest of the day, like you just sweat out your last remaining brain cell, there’s a good chance you need to take in more electrolytes.
