Why is it easier to swim in salty water than in fresh water?

Salty Water

Explanation:

Swimming in Salty water gives us more buoyancy when freshwater does not.

The salt adds mass to the water and makes it more dense, therefore you are able to float a little more than that of freshwater, as there is no salt in there. The denser the water, the more ability you have to float in it.
