You’re not a mood ring. You don’t have to change color every time someone walks in angry.

Someone else’s state is information, not an instruction. A person arriving upset creates a strong pull to match them or to manage them, and if you follow it automatically your own condition ends up set by whoever is loudest in the room. Staying steady is not coldness, and it is often the most useful thing available to them.

When the temperature shifts around you, notice the pull before you follow it. Take a breath and stay where you were. You can be warm toward someone without adopting their weather as your own.
