Scientists have already given their blessings to guilty
pleasures such as nibbling chocolate (it's high in antioxidants) and
sipping wine (red vino is heart-healthy). Now, studies are finding
upsides to other so-called bad behaviors. Some things — like smoking or
an addiction to cookies 'n' cream — we'd never endorse, but these six
naughty habits can feel good and be good for you.
1. Getting pissed off can keep stress in check
A little anger may be a tonic for both your mind and body. For
example, new studies suggest that riled-up people make better decisions.
And researchers at Carnegie Mellon University found that anger — as
opposed to fear or anxiety — can prompt your brain to release less
cortisol, the powerful stress hormone linked to problems like obesity,
bone loss, and heart disease. "Traditionally, it has been difficult for
women to express anger effectively, because we're 'supposed' to act
nurturing and sensitive," says Julie K. Norem, Ph.D., author of The
Positive Power of Negative Thinking. So let your ire out. Just don't go
overboard; chronic rage is unproductive.
2. Downing coffee could cut your cancer risk
Coffee's most exalted attribute — energy-boosting caffeine — has
nothing on its real health superpowers. Studies show that drinking daily
joe may minimize your risk for Parkinson's disease, cancer, and type 2
diabetes. Why? Most chronic diseases are related to inflammation, and
coffee is chock-full of anti-inflammatory compounds, says Shelley
McGuire, Ph.D., an associate professor of nutrition at Washington State
University. Coffee also has more antioxidants than almost any other
food. Sip one to three high-octane or decaf cups a day, but make sure
you steer clear of fat traps such as whipped-cream-topped lattes. "If
you're piling on calories," warns McGuire, "you're probably wiping out
the benefits."
3. Being a slob may help you breathe easier
Messy women everywhere cheered when a British study found that an
unmade bed could nix in-house allergens (turns out, tucked-in sheets can
offer dust mites a covered breeding area). But here's even more
encouraging news for the not-so-tidy: Environmental and internal
medicine expert Kenneth Rosenman, M.D., says you should focus on keeping
your home reasonably clean, not entirely pristine. "The huge push to
disinfect our homes isn't healthy," he explains. "A little messiness is
OK." Zapping every germ around — including the harmless ones — can clear
the way for more serious or resistant strains. Plus, certain household
disinfectant sprays and air fresheners release chemicals that can
heighten asthma risk. Skip spray cleaners in favor of environmentally
friendly pourable ones — and don't forget that a simple clean damp cloth
can do wonders.
4. Drinking beer may benefit your heart and bones
Go ahead, crack open that brewski: Research indicates that beer could
be an even better heart-disease fighter than red wine, says Charles
Bamforth, Ph.D., a professor of food science and technology at the
University of California at Davis. The refreshing stuff is made with
malted barley, which happens to contain the same heart-protecting
antioxidants that give red wine its good name. But beer also packs high
levels of vitamin B6, which keeps our bodies from building up
homocysteine, a chemical linked to increased coronary risk. And your
whole body gets a boost in the form of silica, a compound that helps
strengthen bones. Bamforth suggests sticking to one beer a day. Look for
brews made with ample pale malt and hops (i.e., pale ales), which are
especially rich in silica.
5. Surfing the Internet might tune up your brain
All that online shopping may yield more than a fab pair of heels. A
new study at the University of California at Los Angeles found that just
one week of frequent Web browsing can fire up your brain's
complex-reasoning hubs. "Time online may improve your ability to make
decisions," says study coauthor and psychiatrist Gary Small, M.D. It's
possible that the more we surf, the more efficient our brains can become
at strategizing, he explains. "It's like going to the gym. After a
while, you can lift more weight with less effort." But scientists aren't
giving i-geeks free license to click around all day and night. Take
regular breaks and, adds Small, be sure to socialize with actual humans.
6. Chewing gum can keep you trim
We hate to burst the bubble of etiquette watchers, but recent
research shows that chomping on gum — ever so politely, of course — can
improve both short- and long-term memory (scientists are still figuring
out exactly why). And chewing the stuff might also help you slim down,
according to new research from the University of Rhode Island. Animal
research suggests that frequent chewing can stimulate the brain's
satiety center, which is responsible for making us feel full, says lead
study author Kathleen Melanson, Ph.D., R.D. (Bonus: Her subjects also
had higher energy levels.) Go with a stick of the sugar-free kind.
