(Meredith) - You may need to adjust your thermostat after reading this.
According to the Department of Energy, the coolest you should keep your home is 78 degrees -- and that's during the summer months.
Energy Star, a federal program managed by the DOE and the Environmental Protection Agency, also recommends setting your thermostat to 82 degrees when you're sleeping and 85 degrees when you're not at home.
The agency said following these guidelines can help you save energy and money.
"Set your thermostat as high as comfortably possible in the summer," the DOE said on its website. "The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be."
Several people objected to the department's recommendations on Twitter.
"If you're setting your thermostat above 72 degrees Fahrenheit in the summer, you need to speak to a doctor," one user wrote.

Another person joked that anyone who sets their thermostat to 82 degrees at night "should be arrested."
