Love it or not, your nose can't be ignored. It is a small but mighty part of
our being. And a little pampering -- when a cold or allergies strike -- can go far.
The upside to having a nose is its faithful ability to detect wondrous
aromas. Our nose serves as a sensor, helping us determine if a potential food
source is toxic or edible, friend or foe. The nose knows whether it's
coffee we're sniffing, spoiled leftovers -- or worse.
"In evolution, odors told us what was good for us, what was bad,"
says Pamela Dalton, PhD, MPH, a member of The Monell Chemical Senses Center in
Philadelphia. "It was part of our survival system. If something smelled
bad, it was toxic. If it didn't smell good or bad, it was worth investigating.
If it was the smell of cooked fat, it meant survival."
In fact, scientific evidence suggests -- though far from conclusively --
that a pleasing fragrance actually affects our physiology, helping us
"When animals are exposed to certain scents, there are changes in their
brain chemistry and hormone levels. There is also a reduced activity level, a
measurable change in their behavior. But are they relaxed? It's hard to ask
them," Dalton tells WebMD. "We're also not sure what that means in
terms of people."
After all, there's another factor at work: "Our expectations affect our
reactions," she says. "That's why bakery smells are enjoyable, probably
because they take us back to our childhood."
Taking a Peek Inside
For the best advice on pampering your snout, WebMD contacted those who know
"When you've got a runny nose, the small blood vessels lining the nose
become irritated," says Pedro Cazabon, MD, an internist at the Ochsner
Clinic in New Orleans. "Blowing or rubbing your nose aggravates the nose skin, which is sensitive anyway."
Crazy temperature changes don't help either. In frigid outdoor air, blood
vessels clamp down; warm indoor air opens them up, says Michele McDonald, MD, a
professor of dermatology at Vanderbilt University School of Medicine in
"Any extremity, whether it's the nose or fingers, is affected by
temperature changes because blood vessels are the first to react," she
tells WebMD. "When blood vessels are clamped down, there's less blood flow
to the skin, so skin becomes irritated; it's more susceptible to
The lower humidity indoors and outdoors wreaks its own havoc -- further
irritating nasal skin inside and out. "Your nose tends to dry out,
especially the skin right underneath or between your nostrils," McDonald
Pampering Your Nose
Saunas and steamy showers might seem like the answer to dry indoor
air - and it's true that steamed heat will open up nasal passages. But that's a
temporary fix that really doesn't help much. "Once you go into the cold
air, they will clamp down, which only causes more nose irritation," Cazabon
