Do you ever have thermostat wars in your house? You like it a few degrees cooler while your significant other likes it a few degrees warmer.... So where is the ideal setting for your thermostat?
Most homes and offices keep the temperature set at about 68° to 70°. According to research done by the Helsinki University of Technology, the ideal temperature for productivity is between 70° and 73°. Research has also shown that the ideal sleeping temperature is between 65 and 72°.
But when you're talking about your home, it really doesn't matter what the research says. You should set your thermostat where you feel most comfortable. But if you find yourself in the middle of a thermostat war, keep in mind that you don't want to be changing the temperature more than a couple of degrees or you could be sacrificing efficiency. If you are constantly changing your thermostat temperature more than a couple of degrees either way, your unit will have to work extra hard to keep up. So try to find a happy medium if you can!
