Why is it easier to float in the ocean than in a swimming pool?

All that dissolves salt makes seawater more dense (or heavier) than freshwater – and objects float more easily in dense water  The saltwater of the ocean influences your buoyancy, or the ability to stay afloat. The buoyancy of salt water helps to increase your swimming speed as you will be closer to the surface. Unlike pool swimming, the germ factor in oceans is usually not as serious due to water circulation. Nevertheless, illnesses can result from microscopic sea life or swallowing too much sea water. Free space is also a benefit to ocean swimming; if one area is crowded, you can easily move elsewhere to find a location for uninterrupted swim.
