In winter you can also become dehydrated: less thirst, increased diuresis due to cold, dry air (heating), and "invisible" sweat under layers.

When you have the flu, the most helpful things are simple: rest and fluids. Electrolytes don't cure the flu, but they can help you drink better and maintain balance. Support, not treatment. That's how they fit in.

You think you're tired due to stress, lack of sleep, or feeling "burnt out." But often, the truth is different: you've been losing water and electrolytes for hours without realizing it.
