Warm water
at about 90 degrees Fahrenheit can increase your metabolism and speed when swimming, but a cooler temperature of 70 degrees Fahrenheit is safer for swimming because the body can adjust better to colder temperatures than warm water, according to a 1993 study published in the “The Journal of Sports Medicine …
Do you swim faster in cold water?

Is it easier for humans to float in warm or cool water?

, so objects that float will float higher (easier) in warm water than cold water. Most things expand when they heat up. Their mass stays the same, but their size increases – thus they are less dense and more prone to float.

they generally float easier
.
Why do you think it seems to be easier for a person to float in salt water rather than in a swimming pool?
The reason is:
Buoyancy
– saltwater gives more buoyancy than freshwater because of the higher density of saltwater. Buoyancy makes it easy for the body to stay high in water, thus all other factors being kept equal, one can swim faster in salt water than in freshwater.
