The Science of Our Thermostat Settings

There's an ambient temperature that's particularly good for our mental state

As seasons change, the ambient temperature, inside and out, also changes.

In workplaces and homes, a debate often occurs: What is the best temperature setting for ambient air? Some people feel that no temperature inside is too cold, even one that would lead to the heat being turned on at a different time of year. For other people, no temperature is too warm. How can those two groups be reconciled?

Research consistently shows that our brains function best, and we’re in our best moods, when the thermostat is set to around 70 to 72 degrees Fahrenheit and indoor humidity levels are moderate (40 to 70 percent). Being in a good mood is important because when we are, analytical reasoning, creativity and the ability to get along with others are better than when we are not.
