5. Warm up in Bed
On a cold winter night sometimes it just feels impossible to warm up. You can crank the heat (and crank up your bills), you can plug in a space heater (which has risks and costs associated as well), or you can take the old-fashioned route and use a hot water bottle. Simply fill it with hot water and stick it in your bed, under your blankets, about 10 minutes before you plan to hit the sack. Your sheets will be warm and ready for you to cozy up in no time.
