    What's the easiest way to stay warm in the super cold？1.. At least that's what Santa Claus told me.

Over Christmas, Dennis and I went to Finland. We brought back some tips for keeping warm in a cold temperature.

Three layers（层）work wonders.

Start with the base layer, which sits right on your skin: choose something absorbent（有吸收力的）.2..

A sweater is a good choice. The most important layer is the outer clothes, which should be waterproof（防水的）and windproof.

3..

You lose heat from every millimeter of uncovered skin, which was the biggest lesson I learned on the trip. My whole body was well covered. But I missed one spot: my face. So it often felt like the wind was going to blow my nose off.

Exercise and don't just stand still.

When it's cold, exercising may be the last thing you feel like doing, but be smart.4.. When we first got to Finland, we were freezing. But after a couple of minutes jumping around, we felt less cold.

Have a heater.

You may want to turn it on all the way up, but it's best to keep it between 18 and 20 degrees.5.. Remember not to create a huge difference between inside and outside.
