There
are two positive effects of smoking cigarette. The first is smoking lower risk
of knee-replacement surgery. While smokers might go broke buying a pack of
cigarettes, they can at least save money by avoiding knee-replacement surgery.
Surprising results from a new study have revealed that men who smoke had less
risk of undergoing total joint replacement surgery than those who never
smoked. The study, from the University of Adelaide in Australia, appears
in the July issue of the journal Arthritis & Rheumatism. What could be the
connection? Knee-replacement surgery was more common among joggers and the
obese; smokers rarely jog, and they are less likely to be morbidly
obese. After controlling for age, weight and exercise, the
researchers were at a loss to explain the apparent, albeit slight protective
effects of smoking for osteoporosis. It could be that the nicotine in tobacco
helps prevent cartilage and joint deterioration.
The
second effect is smoking lowers risk of obesity. Smoking, in
particular, the nicotine in tobacco smoke is an appetite suppressant. This has
been known for centuries, dating back to indigenous cultures in America in the
pre-Columbus era. Tobacco companies caught on by the 1920s and began targeting
women with the lure that smoking would make them thinner. A study
published in the July 2011 issue of the journal Physiology & Behavior, in
fact, is one of many stating that the inevitable weight gain upon quitting
smoking is a major barrier in getting people to stop, second only to addiction.
The relationship
between smoking and weight control is complex: Nicotine itself acts
as both a stimulant and appetite suppressant; and the act of smoking triggers
behavior modification that prompts smokers to snack less. Smoking also might
make food less tasty for some smokers, and further curb appetite. As an
appetite suppressant, nicotine appears to act on a part of the brain called the
hypothalamus, at least in mice, as revealed in a study by Yale researchers
published in the June 10, 2011, issue of the journal Science. No respectable
doctor would recommend smoking for weight control, given the toxic baggage
accompanying cigarettes. This recent Yale study, however, does offer an inkling
of hope for a safe diet drug to help obese people control their appetites.
On the other hand, there are also
two negative effects of smoking cigarette. First, one big area of where
smoking harms the body is the heart and lungs. Smoking causes your heart to
work much harder and faster than normal, meaning tremendous stress on that
area. It is because of the blood pressure levels increase as well as the chance
of a heart attack or stroke because the blood vessels are constricted. Smokers
have a greater chance of developing irregular heartbeats than non-smokers. Even
though the heart is beating much faster, Effects on the Body (1997) it is not
able to fully circulate the blood and can result in congestive heart failure.
Because the lungs have to handle so much smoke, the bronchial lining must
thicken for protection. This thickening can lead to a greater chance of lung cancer.
Effects on the Body (1997) As the lungs continually push smoke toxins through
the body; they will lose the ability to add oxygen to the blood, which can
cause difficulty in breathing (emphysema).
Another
huge effect that smoking has on the body is on the skin and in the arms and
legs. Smoking causes vasoconstriction. This is where the blood vessels in your
skin narrow and oxygen and nutrients cannot get to the skin cells.
Vasoconstriction usually occurs in the facial area where one might get premature
wrinkling with, Effects on the Body (1997) feet around the eyes and pale, gray
skin on the cheeks. Smokers are usually the only group at risk of getting
peripheral vascular disease. This is where the blood vessels in the arms and
legs have narrowed, which in turn may lead to an amputation of a limb in the
future.
In summary, there are always positives and negatives
of smoking cigarette. As we know that, in public always show the negative
effect of smoking cigarette especially in the cigarette’s pack itself. People
can freely choose whether they want to smoke or to stop smoking cigarette. They
know the bad and the good effect of smoking cigarette. My suggestion is keep
health and take care of your body.
