Although a new study finds that unplanned attempts to quit smoking and reduce cardiopulmonary risk factors can be successful, using alternative therapies to reduce stress associated with the change could benefit those looking to stop.

Researchers from the University of Pittsburgh found that long periods of subconscious dissatisfaction with the habit and noted that 40 percent of the participants had begun cessation programs spontaneously.

To improve success, co-author Dr Saul Shiffman says that, "all smokers should consider ways to manage tough situations such as cravings and withdrawal symptoms to ensure long-term success."

Beginning programs that incorporate yoga or Tai Chi could be effective for smokers of any age who want to stop smoking and reduce the associated stress, according to Dr Dolores Mendelow, clinical assistant professor of pediatrics and communicable diseases at the University of Michigan Medical School.

She says that both Eastern practices can be effective in helping patients remain calm even in children, adding "mind and body therapies, such as Tai Chi, help reduce the risk of depression and anxiety," and calls them a safe and effective way to improve health outcomes.
