Secondhand Smoke Exposure For Just 20 Minutes Leads To ...

It only takes 20 minutes of secondhand smoke exposure before breathing is impaired, a new study shows.

Researchers from the University of Athens, the Hellenic Cancer Society and the Harvard School of Public Health had 15 healthy study participants go inside a chamber meant to simulate a bar or car filled with secondhand smoke particulates for 20 minutes to see how their breathing was impaired.

In just that short amount of time, air flow through the participants' airways was impeded.

"The observed short-term effects of secondhand smoke tell us that even a short exposure is indeed harmful for normal airways," study researcher Dr. Panagiotis Behrakis, M.D., FCCP, of the University of Athens, said in a statement.

The new findings were presented at the annual meeting of the American College of Chest Physicians; because the study has yet to be published in a peer-reviewed journal, findings should be regarded as preliminary.

Similarly, a study published in 2007 in the American Journal of Public Health showed that cancer-causing NNK -- a compound that comes from the smoke of cigarettes -- builds up by 6 percent every hour in bar- and restaurant-workers who are exposed to secondhand smoke during their night shifts, TIME reported.

"We were somewhat surprised by the immediacy of the effect and the fact that we could measure the average hourly increase," study researcher Michael Stark, principal investigator at the Mulmomah County Health Department in Oregon, told TIME.

Earlier this year, a study in the American Journal of Public Health showed just how many lives secondhand smoke claims in the U.S. each year: 42,000, Livescience reported.

Trying to kick the habit? Click through the slideshow for some natural options that could help:

• Mindfulness

  Mindfulness training helped participants in a <a href="http://www.ncbi.nlm.nih.gov/pubmed/21723049" target="_hplink">2011 <em>Drug and Alcohol Dependence</em> study</a> to stay off cigarettes. That study included 88 people who smoked 20 cigarettes daily, on average, who were split up into two groups: One received four weeks of mindfulness training, while the other group went through four weeks of an <a href="http://www.ffsonline.org/" target="_hplink">American Lung Association stop-smoking program</a>. The researchers found that more of those who went through the mindfulness training smoked fewer cigarettes -- and stayed off them -- than those who went through the other stop-smoking program. The mindfulness training included <a href="http://www.psychologytoday.com/blog/minding-the-body/201204/can-mindfulness-help-you-quit-smoking" target="_hplink">realizing when you're facing a craving</a>, accepting it, thinking about what's happening and then taking note of the sensation (whether it's tightness or pressure), <em>Psychology Today</em> reported.

• Weight Lifting

  Jogging and bicycling aren't the only exercises that could help you kick the smoking habit -- <em>Shape</em> magazine reported that <a href="http://www.shape.com/latest-news-trends/study-says-weight-lifting-can-help-smokers-quit-and-lose-weight" target="_hplink">weightlifting could help</a>, too. The research, published in the journal <em>Nicotine & Tobacco Research</em>, showed that doing two hour-long weightlifting sessions for 12 weeks <em>plus</em> undergoing treatment to quit smoking was linked with greater success in quitting smoking, compared with just undergoing the stop-smoking treatment.

• Eat Produce

  <a href="http://www.huffingtonpost.com/2012/06/10/fruits-vegetables-quit-smoking-smokers-tobacco_n_1581465.html" target="_hplink">Eating lots of fruits and veggies</a> could help smokers maintain a tobacco-free lifestyle, according to research from the University of Buffalo. The study, published in the journal <em>Nicotine and Tobacco Research</em>, included 1,000 smokers ages 25 and older. The researchers had the participants answer surveys about their smoking habits and their fruit and vegetable intake. Then, they followed up with them 14 months later and asked them if they used tobacco over the past month. The researchers found that there was a relationship between the <a href="http://www.huffingtonpost.com/2012/06/10/fruits-vegetables-quit-smoking-smokers-tobacco_n_1581465.html" target="_hplink">amount of fruits and vegetables</a> the study participants ate, and the likelihood that they quit -- and stayed off -- tobacco. In fact, people who ate the most produce in the study were three times more likely to report that they'd been tobacco free in the previous month. The researchers also found a link between increased produce consumption and taking longer in the day to have the first cigarette, smoking fewer cigarettes, and decreased dependence on nicotine (based on test results).

• Acupuncture And Hypnosis

  A review of studies suggests there is evidence that <a href="http://www.huffingtonpost.com/2012/05/07/acupuncture-quit-smoking-hypnosis_n_1497348.html" target="_hplink">acupuncture and hypnosis</a> can work to help quit smoking, Reuters reported. Researchers, who published their findings in the <em>American Journal of Medicine</em>, said that other options -- like medications and counseling -- should be tried first, but that <a href="http://www.huffingtonpost.com/2012/02/11/hypnosis-quit-smoking_n_1248444.html" target="_hplink">hypnosis</a> and acupuncture could help if those options don't work, or if people don't want to go on medications, according to Reuters.

• Text Messages

  Who knew your phone could be used to help you quit smoking? A recent study published in the <a href="http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(11)60701-0/abstract" target="_hplink">journal <em>The Lancet</em></a> showed that smokers who enrolled in a <a href="http://www.huffingtonpost.com/2011/07/05/smoking-text-message_n_888188.html" target="_hplink">program called "txt2stop"</a> -- where they received encouraging text messages to quit smoking -- were twice as likely to kick the habit after six months, compared with smokers who didn't get any encouraging messages. In the study, conducted by the London School of Hygiene & Tropical Medicine, one group was able to text words like "lapse" and "crave" to a phone number, and <a href="http://news.cnet.com/8301-27083_3-20075843-247/want-to-quit-smoking-try-text-message-support/" target="_hplink">received an encouraging text</a> message in return, CNET reported. The other group of people, however, only got one text message every two weeks, and that message just thanked them for being part of the study.
