Because, sweat attracts mosquitoes.

sweat are salty.

Are salt water and sweat almost the same thing ?

Salt water does not attract mosquitoes, mosquitoes are attracted to sweat because of its odour, we give off hundreds and thousands of scents that bugs love, also mosquitoes are attracted to the lactic acid on the human skin.

Not particularly. But if it smells like "B.O."- you're "Breakfast, Lunch & Dinner"- as far as a Mosquito is Concerned. :(
