It's winter. Here are some easy tips to follow to get through it.

Warm yourself first.

It's easier to change your body temperature than room temperature, not to mention more eco-friendly. Instead of turning up the heat, put on another layer of clothing.

Your mom may have said that you lose 80 percent of your body heat through your head, but that's not actually true. If you're otherwise clothed, you'll lose heat from any surface that's exposed. So put on your hat, even if you're inside.

Warm air rises to the ceiling. Run your fan on its lowest setting in a clockwise direction to push the warm air back down to where you can feel it.

Hot showers immediately warm you up, but cold showers improve blood circulation between your skin and organs. Cold showers are also correlated with a stronger immune system.

Keep heat in and cold out by cutting a pool noodle in half lengthwise, wrapping it in fabric, and sliding it under your door. It'll stay put all winter, and you can re-use it at the pool come summer. (But we recommend you spring for a new one.)

Another two words: Obvious, right?Stay toasty on schedule, so you never go home to a living room that's colder than outside. You can even do it with your smartphone.

Not everyone has access to adjust the thermostat in their apartment or office building. If that's the case, you may need to outsmart the device by making it "think" the room is colder than it actually is. Putting ice near itoften does the trick.

If you're not wearing a tank top or going sleeveless, your windows shouldn't, either. Replace thin curtains with heavier wool or fleece drapes in the winter. But be sure to open them on sunny days for free heat.

Using your oven heats up the whole house. You'll feel even cozier if you invite friends—and all their body heat—over to eat four dozen cookies.

Using these easy tips will make winter way easier to deal with.
