The Effects of Smoking on the Body
Tobacco smoke is enormously harmful to your health. There’s ...view middle of the document...
As that effect subsides, you feel tired and crave more. Nicotine is habit forming.
Smoking increases risk of macular degeneration, cataracts, and poor eyesight. It can also weaken your sense of taste and sense of smell, so food may become less enjoyable.
Your body has a stress hormone called corticosterone, which lowers the effects of nicotine. If you’re under a lot of stress, you’ll need more nicotine to get the same effect.
Physical withdrawal from smoking can impair your cognitive functioning and make you feel anxious, irritated, and depressed. Withdrawal can also cause headaches and sleep problems.
When you inhale smoke, you’re taking in substances that can damage your lungs. Over time, your lungs lose their ability to filter harmful chemicals. Coughing can’t clear out the toxins sufficiently, so these toxins get trapped in the lungs. Smokers have a higher risk of respiratory infections, colds, and flu.
In a condition called emphysema, the air sacs in your lungs are destroyed. In chronic bronchitis, the lining of the tubes of the lungs becomes inflamed. Over time, smokers are at increased risk of developing these forms of chronic obstructive pulmonary disease (COPD). Long-term smokers are also at increased risk of lung cancer.
Withdrawal from tobacco products can cause temporary congestion and respiratory pain as your lungs begin to clear out.
Children whose parents smoke are more prone to coughing, wheezing, and asthma attacks than children whose parents don’t. They also tend to have more ear infections. Children of smokers have higher rates of pneumonia and bronchitis.
Smoking damages your entire cardiovascular system. When nicotine hits your body, it gives your blood sugar a boost. After a short time, you’re left feeling tired and craving more. Nicotine causes blood vessels to tighten, which restricts the flow of blood (peripheral artery disease). Smoking lowers good cholesterol levels and raises blood pressure, which can result in stretching of the arteries and a buildup of bad cholesterol (atherosclerosis). Smoking raises the risk of forming blood clots.
Blood clots and weakened blood vessels in the brain increase a smoker’s risk of stroke. Smokers who have heart bypass surgery are at increased risk of recurrent coronary heart disease. In the long term, smokers are at greater risk of blood cancer (leukemia).
There’s a risk to nonsmokers, too. Breathing secondhand smoke has an immediate effect on the cardiovascular system. Exposure to secondhand smoke increases your risk of stroke, heart attack, and coronary heart disease.
Skin, Hair, and Nails (Integumentary System)
Some of the more obvious signs of smoking involve the skin. The substances in tobacco smoke actually change the structure of your skin. Smoking causes skin discoloration, wrinkles, and premature aging. Your fingernails and the skin on your fingers may have yellow staining from holding cigarettes. Smokers usually develop...
