Natural Stone Tile Surface Finishes. The face of stone tile flooring typically has one of three types of finishes applied: natural, honed, or polished. The finishing process of natural stone begins once the stone is quarried and cut into a rough slab. The rough slab face is polished with abrasive pads.
The best air conditioning temperature for sleeping is whatever you can get by on with just a sheet over you. If you have the air conditioner set so low that you need pajamas and a comforter, you have it set too low. Try working your way up from that 82F to 84F, 86F, or even higher.
The difference in where you set the thermostat only affects how much cold air it blows into the room. The lower temperature at which you set the thermostat in summer, the more air it blows in. Setting the thermostat at 78 degrees typically keeps enough cool air in the room for comfort. Unless you developed a keen temperature sensitivity, you won't likely notice the difference between 73 degrees and 78 degrees.
