冬天必备技能：9种不开暖气的保暖法

It's freezing out and we wish our homes could be a little warmer. And while we all know the standard practices from adjusting the thermostat to making sure our windows are sealed and lighting a fire, there are definitely some tricks we're missing.
外面天寒地冻，我们真希望屋里能暖和点。我们熟知的保暖标准方法无外乎调高空调的温度，把窗户关严实，壁炉里生起火。还有些保暖小绝招是你不知道的哟。

1. Close off unused rooms.
不使用的房间就关上房门。

Keeping doors closed won't just prevent cold air from moving into the rest of the house -- it will help contain the heat you've generated.
保持房门关闭不仅可以防止冷空气进入其他房间，还可以保存已经产生的暖气。

2. Set your ceiling fans to rotate clockwise.
让吊扇顺时针旋转。

Whether you know it or not, your ceiling fan needs to be changed seasonally. By setting them clockwise in the winter at a lower speed, you can drive warm air down towards you and your guests.
你可能不知道，你应该按季节调整吊扇的运转方向。在冬天，让吊扇以顺时针方向低速运转，可以将暖空气抽下来，为你和家里的客人保暖。

3. Change your sheets.
换张床单。

Again, sometimes simple is tremendously effective when it comes to keeping warm. Swap cotton for flannel sheets, grab a down comforter and don't forget about the value of extra blankets.
这再一次证明，小小的保暖绝招可以发挥大大的用处。把棉布的床单换成法兰绒的，铺床羽绒被，别忘了再铺上毯子哟。

4. Add some layers to your floor.
加层地毯。

Area rugs aren't just a way to add color and style -- they were invented for the practical reason of keeping your floors cozy. Floors account for as much as 10 percent of heat loss if they're not insulated, according to the National Energy Foundation, and rugs can be that missing insulation. They'll keep cool air from seeping up into the room, and your toes will definitely thank you.
区域地毯不仅可以使地面看起来有色彩层次，格调十足，还有很实际的作用——使你家的地板踩上去暖绵绵暖烘烘。根据英国国家能源基金会研究表明，因为没有对地板采取隔热措施导致的热量流失占到了10%之多，而区域地毯正可以解决这一问题。地毯可以防止冷空气渗入室内，你的脚趾一定会感激你的。
