Smokers who are trying to cut down or quit might want to go
for a jog the next time a cigarette craving overcomes them,
according to a British study.
Researchers, whose findings appeared in the journal
Addiction, combined the data from 19 previous clinical
trials and found that a bout of exercise generally helped
hopeful quitters reduce their nicotine cravings - although
whether that translated into a greater chance of quitting was
"Certainly, exercise seems to have temporary benefits, and as
such can be strongly recommended," said Adrian Taylor, a
professor of exercise and health psychology at the University
of Exeter in Britain, who led the study.
In the trials used for the study, smokers were randomly
assigned to either exercise - most often, brisk walking or
biking - or some kind of "passive" activity, such as watching
a video or just sitting quietly.
Overall, Taylor's team found, people said they had less
desire to smoke after working out than they did before.
Exactly why is not clear. Exercise may serve as a
distraction, while being active might also boost people's
mood, so that they don't feel as great a need to feel better
by smoking, Taylor said.
None of the smokers in the studies was in a quit program or
using nicotine replacement products, such as gums or patches.
Since nicotine replacement therapy curbs cravings, exercise
might have less of an effect on smokers using these products.
