Spraying water onto floor to reduce temperature may not bring up the expected outcome; instead, you may feel hotter than before.

Evaporated water vapor can condense on the body skin. Evaporation energy of water is 40.65 kJ/mol, so, assume 5.56mol (100g) water condense on the body skin, this would provide at least 225.5 kJ to the body. Assume the specific heat of the human body is 3.47 kJ · kg⁻¹· °C⁻¹, weight around 50 kg, it would increase the body temperature for 1.3 °C.

However, the condensation is not happened momentary in real life, so above calculation is not fully correct. Still, the raise of body temperature would happen and drive you to turn on the air con.
