Baby, it's Cold Outside
Today, December 28, 2017, the temperature in Montclair, NJ,
is 12 degrees Fahrenheit. It’s not only below freezing, but it’s also a shock
after a beautifully hospitable and warm fall and a mild winter---at least until
now.
So what else is there to do besides drink hot drinks
indoors? In fact, I’ve been drinking lots of hot, healthy coffee indoors (and
out)---at the ice skating rink, with friends at cafes, alone at home, and at
the office (of course).
Coffee increases the
perception of likability
So the obvious takeaway is that hot drinks in cold weather
make us feel better. However, there’s more to hot coffee-cold weather
arithmetic than physiologic comfort. In one study,
conducted at the University of Colorado, researchers recruited 41 undergrads,
who were primed with either hot coffee or iced coffee before walking into the
testing site.
They were then asked to complete a personality impression questionnaire, in which they were given information about a particular individual (Person A). Some of the highlighted traits were being cautious, competent, and industrious. Subsequently, the investigators asked the students to rate the individuals on warmth and likability. Students who were primed with hot coffee (versus cold coffee) were significantly more likely to rate Individual A as warm and likable.

The implications for these findings, which have been
reinforced in numerous studies, with different designs and various endpoints,
are numerous, but pretty intuitive. For example, if you are trying to sell
someone an idea or product, give them a hot cup of coffee (or tea or hot
chocolate) when they arrive. Likewise, in social interactions, when you want to
put others at ease simply to make them happy and improve the experience, get
the coffee pot brewing, because therein lies the secret to feeling warm and
cozy in new surroundings.
Coffee + Coldness=Amped-up Calorie Burning
In reality, we can’t always be inside drinking coffee---just
because it’s cold outside. Sometimes we have to be outside, or we choose to be
outside. I like hiking in cold weather (not frigid weather like today though).
It feels more vigorous, challenging and ultimately rewarding when there’s the
added cold-weather factor. Plus, there’s a major upside. Scientists have found
that cold weather increases metabolism. In fact, some people consider enduring
cold weather a form of exercise, because the body has to work harder to
generate body heat.
And when you add the calorie-busting, metabolism-boosting
effect of coffee, which increases basal metabolism by 5%-8%, you can really
burn a bunch of calories, and even lose weight if that’s on the agenda for you.
Baby, it's Cold Outside (stay for coffee)
And now, an ode to the cold, featuring Louis Armstrong and
Ella Fitzgerald: “Baby it’s Cold Outside”---such a sexy, sultry, romantic song
that makes one yearn for coffee….amongst other things.
Happy New Year to you all!
