EFFECTS OF SMOKING ON YOUR BODY

Do you smoke? If you do, it is really important to know some things about the damage done in your body by smoking. In our days is very common to see people smoking and sometimes under age people. Smoking a lot causes some effects like lung and mouth cancer, ulcers and also the passive smokers can be damged by people who smoke.

Tobacco smoke contains dangerous chemicals

The most damaging compounds in tobacco smoke include:

• Tar – this is the collective term for all the various particles suspended in tobacco smoke. The particles contain chemicals including several cancer-causing substances. Tar is sticky and brown, and stains teeth, fingernails and lung tissue. Tar contains the carcinogen benzo(a)pyrene that is known to trigger tumour development (cancer).
• Carbon monoxide – this odourless gas is fatal in large doses because it takes the place of oxygen in the blood. Each red blood cell contains a protein called haemoglobin – oxygen molecules are transported around the body by binding to, or hanging onto, this protein. However, carbon monoxide binds to haemoglobin better than oxygen. This means that less oxygen reaches the brain, heart, muscles and other organs.
• Hydrogen cyanide – the lungs contain tiny hairs (cilia) that help to clean the lungs by moving foreign substances out. Hydrogen cyanide stops this lung clearance system from working properly, which means the poisonous chemicals in tobacco smoke can build up inside the lungs. Other chemicals in smoke that damage the lungs include hydrocarbons, nitrous oxides, organic acids, phenols and oxidising agents.
• Free radicals – these highly reactive chemicals can damage the heart muscles and blood vessels. They react with cholesterol, leading to the build-up of fatty material on artery walls. Their actions lead to heart disease, stroke and blood vessel disease.
• Metals – tobacco smoke contains dangerous metals including arsenic, cadmium and lead. Several of these metals are carcinogenic.
• Radioactive compounds – tobacco smoke contains radioactive compounds, which are known to be carcinogenic.

Effects of smoking on the respiratory system

The effects of tobacco smoke on the respiratory system include:

• Irritation of the trachea (windpipe) and larynx (voice box)
• Reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages
• Impairment of the lungs’ clearance system, leading to the build-up of poisonous substances, which results in lung irritation and damage
• Increased risk of lung infection and symptoms such as coughing and wheezing
• Permanent damage to the air sacs of the lungs.

Effects of smoking on the circulatory system

The effects of tobacco smoke on the circulatory system include:

• Raised blood pressure and heart rate
• Constriction (tightening) of blood vessels in the skin, resulting in a drop in skin temperature
• Less oxygen carried by the blood
• Stickier blood, which is more prone to clotting
• Damage to the lining of the arteries, which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls)
• Reduced blood flow to extremities like fingers and toes
• Increased risk of stroke and heart attack due to blockages of the blood supply.

Effects of smoking on the immune system

The effects of tobacco smoke on the immune system include:

• The immune system doesn’t work as well
• The person is more prone to infections such as pneumonia and influenza
• Illnesses are more severe and it takes longer to get over them.
• Lower levels of protective antioxidants (such as Vitamin C), in the blood.

Effects of smoking on the musculoskeletal system

The effects of tobacco smoke on the musculoskeletal system include:

• Tightening of certain muscles
• Reduced bone density.

Other effects of smoking on the body

Other effects of tobacco smoke on the body include:

• Irritation and inflammation of the stomach and intestines
• Increased risk of painful ulcers along the digestive tract
• Reduced ability to smell and taste
• Premature wrinkling of the skin
• Higher risk of blindness
• Gum disease (periodontitis).

Effects of smoking on the male body

The specific effects of tobacco smoke on the male body include:

• Lower sperm count
• Higher percentage of deformed sperm
• Genetic damage to sperm
• Impotence, which may be due to the effects of smoking on blood flow and damage to the blood vessels of the penis.

Effects of smoking on the female body

The specific effects of tobacco smoke on the female body include:

• Reduced fertility
• Menstrual cycle irregularities or absence of menstruation
• Menopause reached one or two years earlier
• Increased risk of cancer of the cervix
• Greatly increased risk of stroke and heart attack if the smoker is aged over 35 years and taking the oral contraceptive pill.

Effects of smoking on the unborn baby

The effects of maternal smoking on an unborn baby include:

• Increased risk of miscarriage, stillbirth and premature birth
• Low birth weight, which may have a lasting effect of the growth and development of children. Low birth weight is associated with an increased risk for heart disease, stroke, high blood pressure, being overweight and diabetes in adulthood
• Increased risk of cleft palate and cleft lip
• Paternal smoking can also harm the fetus if the non-smoking mother is exposed to second-hand smoke.

If the mother or father continues to smoke during their baby’s first year of life, the child has an increased risk of ear infections, respiratory illnesses such as pneumonia and bronchitis, sudden infant death syndrome (SIDS) and meningococcal disease.

To conclude, smoking is bad for your health, because it produces a lot of damage and in extreme cases: the death. Smoking is like a slow death, so if you are smoker, you are in risk, you are dying, so be careful with that.
