During this extreme cold snap, are you preparing your house so the pipes don't freeze?

I set my thermostat up a degree or two and have opened all the cupboards and cabinets attached to an outside wall of the house.
The cupboards under the sink are open as are the medicine cabinets.
I do not want the water pipes to freeze. Allowing inside air to circulate will help keep the pipes and cabinet contents closer to room temperature.
I also leave nightlights on so I don’t trip over anything.
Are you doing anything special?
