Last week, three prominent neurosurgeons told CNN interviewer Larry King that they did not hold cell phones next to their ears. Dr. Keith Black, Dr. Vini Khurana, and CNN’s chief medical correspondent, Dr. Sanjay Gupta all maintained that the practice could be unsafe.

Along with Senator Edward M. Kennedy’s recent diagnosis of a glioma, a type of tumor that critics have long associated with cell phone use, the doctors’ remarks have helped reignite the debate about cell phones and cancer.

According to the Food and Drug Administration, three large epidemiology studies since 2000 have shown no harmful effects. However, that the average period of phone use in those studies was about three years, which provides no information about the long-term exposures that could lead to cancer.

“What we’re seeing is suggestions in epidemiological studies that have looked at people using phones for 10 or more years,” says Louis Slesin, editor of Microwave News, an industry publication that tracks the research.

Little exercise can help smokers quit

[amazon_link asins=’B071RGB6KD,0615482155,B01N6OYT6B,B01N7KMSCB’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’7266958a-6456-11e7-b739-8f0ec31b4940′]

As little as five minutes of exercise could help smokers quit, says a new study.

CLICK & SEE

Research published in the international medical journal Addiction showed that moderate exercise, such as walking, significantly reduced the intensity of smokers’  nicotine withdrawal symptoms.

If we found the same effects in a drug, it would immediately be sold as an aid to help people quit smoking,  said Dr Adrian Taylor, the study’s lead author and professor of exercise and health at the University of Exeter.

Taylor and colleagues reviewed 12 papers looking at the connection between exercise and nicotine deprivation. They focused on exercises that could be done outside a gym, such as walking and isometrics, or the flexing and tensing of muscles.

According to their research, just five-minutes of exercise was often enough to help smokers overcome their immediate need for a nicotine fix.

After various types of moderate physical exertion, researchers asked people to rate their need for a cigarette. People who had exercised reported reduced a desire. “What’s surprising is the strength of the effect,” said Dr Robert West, professor of health psychology at University College London. West was not involved in the review.

“They found that the acute effects of exercise were as effective as a nicotine patch,” he said. West cautioned that it was unknown how long the effects of exercise would last. “You could in theory use exercise to deal with short bouts of nicotine cravings, but we don’t know if it would help in the longer term,   he said
