4. "If your feet are cold, put on a hat." Fact: We do not lose more heat from our heads than from any other portion of the body with the same surface area.

Let's say there's nothing special about your head - fine. So if you're feet are cold, don't bother putting on a hat? According to the article, your head is 10% of your body's surface area and therefore responsible for 10% of the heat loss. It is also the only part of the body I've seen people routinely neglect to cover in the coldest of weather.

If your feet are cold and every other part of your body is covered, put on a hat. Trust me.
