Sleeping cold is a better way of life. It forces your body to burn more calories throughout the night. It tunes you to the natural environment around you. It lessens the shock of cold nights spent under the stars.

This Fall and Winter, I’ve challenged myself not to use heating. The past week has been tough – my glasses frost over in the morning, the inside of my window blankets itself with ice. Today, I can still see my breath, but for the first time since returning from New York, the apartment is above freezing.

Many thanks to the sheep of New Zealand.
