How might smoking increase the risk of cancer in the breast, an organ that is not exposed to smoke?
Both engaged and aloof tobacco smoke display have been connected to non-respiratory tumors. Animated cigarette smoking has been run around with tumor of the bladder, cervix, stomach, pancreas, and kidney. The impacts of latent display to tobacco smoke have been examined significantly less, but affiliations with cervical growth in grown-up ladies, as well as leukemia and mind disease in tykes, have been reported.

What happens to my body as I inhale cigarette smoke?
It just brings seconds for nicotine to range the mind, but its belongings can final for a whole day. Unfortunately, corticosterone, the anxiety hormone, decreases nicotine's effectuality. This implies that if you’re focused on you will utilize more nicotine to feel an effect. As you are able to picture, the more you smoke, the higher your tolerance for nicotine, and the more ward you come to be on the pill. When compelled to strive for an extended period without smoking you will no doubt feel bothered and more onrushing. Moreover, in case you observe or not, your cognitive working should most obviously be disabled.
What are the short-term and long-term health risks of smoking?
Short-term:
* Stained nails and teeth
* Bad breath
* Wrinkled, aged skin
Long-term:
* Lung cancer
* Emphysema
* Heart disease
* Earlier menopause in women
* Death

ATHEROSCLEROSIS
Research has shown conclusively that smoking accelerates arteriosclerosis (hardening of the arteries) and atherosclerosis (a type of arteriosclerosis characterized by fatty deposits in the artery walls), increasing the risk of heart disease, stroke, and peripheral vascular disease. Consequently, smokers have a higher risk of cardiovascular disease in general, and heart attacks in particular, than nonsmokers.
Cigarettes may promote atherosclerosis by a va- riety of mechanisms. Smoking increases the levels of carbon monoxide, a poisonous gas that is inhaled in smoke. Over the long term, this increased level of carbon monoxide from the inhaled smoke itself contributes to damaging the lining of the blood vessels and accelerates the process of atherosclerosis.
Smoking also affects serum cholesterol. Smokers tend to have decreased levels of high-density lipoproteins (HDL—the “good cholesterol) and increased levels of low-density lipoproteins (LDL-the “bad’ cholesterol) and triglycerides (a blood fat), thereby raising the risk and severity of atherosclerosis.
Blood levels of fibrinogen, a component of blood necessary for clotting, are raised by smoking. This may increase the likelihood of blood clots forming and blocking the coronary arteries, leading to a heart attack or stroke. Such clots are most likely to form on areas of the endothelium (the inner lining of blood vessel walls) that are clogged by atherosclerotic plaque and have been roughened by prior damage, rather than on those that remain smooth and intact. Smoking may also cause blood platelets to clump abnormally, adding to the risk of clotting.
Stopping smoking results in an increase in the ratio of HDL to LDL cholesterol and lowers the level of fibrinogen in the blood. Both of these changes help reduce the risk of a heart attack.

Birth Weight
A definite, well-established relationship exists between smoking and low birth weight defined as birth weight less than 2500 grams. In general, the average reduction in birth weight seen in smoking women is 200 grams. This results in a doubling of the incidence of low birth weight infants. The risk and magnitude of low birth weight is related to the number of cigarettes smoked during pregnancy. The critical period during which smoking exerts its deleterious influence has not been determined, but it has been shown that if women cease smoking during pregnancy the infant’s birth weight will be comparable to a non-smoker.
The exact mechanism for decreased birth weight is unclear. At the present, there is evidence that smokers do not consume fewer calories or have less weight gain during pregnancy so it has been concluded that the decrease in birth weight seen in infants of smokers is not due to nutritional factors. Anthropomet- ric studies comparing the differences in body composition in infants of women who smoke with those of non-smokers have found a decrease in the fat-free mass. Specifically, weight and length were decreased in the infants of smokers, but no differences in skinfold and limb circumference measurements were seen. It is unknown whether the physiological effects of smoking on fetal growth are due to the vasoconstrictive properties of nicotine on uterine blood or the decreased oxygen availablity due to carbon monoxide and the formation of carboxyhemoglobin.

Smoking – now it makes me sick!
I bet, you’ve read lot’s of articles and get acquainted with variety of ways people go in order to quit. And then, you understand that all of them are not precisely what you need. Why?
This question can be answered differently. Maybe, your health is not good enough to accomplish success in one of those or your financial possibilities are too small to take an expensive course.
So, first I will clarify the way I advise you here.
This method is for those who are not suffering from serious diseases (exept smoking). Your general state of health has to be good enough to use this method.
In order to quit you must leave smoking for a few days – better a weak – and then sit and smoke out from five to ten cigarettes, one after another. It is a big chance you’ll get yourself poisoned with nicotine, but you’ll probably forget about smoking for a long-long time.
The method has its psychological and physiological factors.
When you stop smoking for a few days, your organism starts to feel “nicotine hunger”. Then you smoke out a big number of cigarettes at a time, you get an overload, which leads to a situation, when nicotine makes you sick (even it’s smell). It takes not much time to forget about your bad habit.
Psychological factor of this method is that of over satisfying your necessity.
Good luck, and look forward to the next post!

Smoking and Pregnancy
Cigarette smoke contains more than 2000 chemicals. We don’t know which of these chemicals are harmful to the developing baby, but both nicotine and carbon monoxide play a role in causing adverse pregnancy outcomes.
Smoking nearly doubles a woman's risk of having a low-birthweight baby. The more a pregnant woman smokes, the greater her risk of having a low-birthweight baby. However, if a woman stops smoking even by the end of her second trimester of pregnancy, she is no more likely to have a low-birthweight baby than a woman who never smoked!
There are so many symptoms, that you can get during the pegnancy, that it is better not to smoke at all. Diabetes, depresssion...
But how can a woman say “no” to a cigarette that had attracted her every day? Studies suggest that certain factors make it more likely that a woman will be successful in her efforts to quit smoking during pregnancy. These include:
- Attempting to quit in the past
- Having a partner who doesn't smoke
- Getting support from family or other important people in her life
- Understanding the harmful effects of smoking
