Smoking &
Physical Activity
According
to the public agency of Canada, physical activity plays an important role in
the health and well being of all Canadians. Those that live physically active
lives generally live more productive lives, and are more likely to avoid
illness and injury.
It’s no surprise that smoking impedes physical
activity. Research reports illustrate 18% of deaths each year are associated
with the harmful effects of cigarette smoking. These harmful effects are most
often linked to diseases within the cardiovascular system. Quitting smoking today could greatly improve your cardiovascular
fitness in as little as two to eight hours.
Tar is the toxic chemical that is found in
cigarettes. This tar slowly clouds the alveoli in your lungs. Alveoli are delicate microscopic bubbles that fill
your lungs and are connected to airways that carry air in and out of them. They
are extremely thin sacks of tissue holding a network of capillaries, or minute
blood vessels. Alveoli expose all of your blood, one single red blood cell at a
time; to the fresh air you fill your lungs with every breath you take.
Perfusion, or blood flow, must match ventilation so oxygen diffuses into your
blood and CO2 diffuses out properly. You cannot ventilate properly without
healthy alveoli.
Smokers’ lungs
have less surface area and fewer small blood vessels. So the lungs receive less
food and oxygen than they need to function normally. Every puff of smoke
inhaled causes the airways to constrict. Over time, the narrowing of
airways causes irreversible lung damage.
Cardiovascular fitness and heart rate response to
exercise are already reduced in young healthy smokers. In men, the adverse
effects of smoking become stronger with increasing age but appear to be
reversible at age 36.
A number of physical endurance
studies have shown that that smokers reach exhaustion before non-smokers do and
can’t run as far or as fast as non-smokers. Additional results noted that
smokers:
o Obtained less benefit from physical
training
o Had less muscular strength and
flexibility
o Experienced disturbed sleep patterns
o Suffered from shortness of breath
almost three times as often as non-smokers
Smoking also affects your bones and
joints, putting you at increased risk for developing the following conditions:
o Osteoporosis
o Hip fractures
o Rheumatoid arthritis etc.
Young people who smoke experience the
same negative effects of tobacco that adult smokers do. This includes not only
lower physical endurance and performance compared to their non-smoking peers,
but also shortness of breath, increased sports-related injuries, and poorer
overall health.
Smoking young adults can also slow
down their lung growth, impair lung function, and cause their hearts to beat
faster than those of non-smokers.
Fortunately for both adult and young
smokers, many of the effects of smoking can be reversed if and when they quit
smoking.
Habitual physical activity is easier than you
think. It can be met through planned exercise sessions, active forms of
transportation like walking or biking, as well as recreation and sports.
To make physical activity apart of your daily
routine check out Leave the Pack Behinds’ QUITRUNCHILL program for smokers and non-smokers. This free, online-based
program assumes that everyone wants to be a bit healthier. It offers facts
about quitting, being active, and managing stress in a healthier manner. Be
