How healthy is Sweating from exercice ?

Summer is coming in a few months.

How healthy is sweating (from cardio or exercice) ?

Sweating can make you lose water weight which can be a good thing if you have excess water

But it also makes you lose some important minerals right ?

Things are probably more complex than that. Is sweating healthy ? Does it make you expel toxins ?

I have an exercice bike at home, I sweat when I do my session, though in Summer it will make me sweat a lot more because the temperature in my flat will be higher

your opinions..?
