Make your presence improve the environment.

You change a room whether or not you intend to. Your attention, tone, and standard all set something that others adjust to, and the effect is largest with the people who have the least power. Most of that influence is exercised without any awareness of it.

Pick one setting you are regularly in and take responsibility for its temperature this week. Ask a real question, notice someone, lower the tension. Small deliberate acts change environments more than any policy does.
