MALADIES OF THE 21ST CENTURY
We entered the 21st century with such maladies as heart and vascular system diseases, environmental diseases, cancer, AIDS (Acquired Immune Deficiency Syndrome). The risk factors causing these diseases are poor environment (especially after Chernobyl disaster), constant stress and bad habits. We witness more and more cases when people suffer from such environmental diseases as food allergies, chronic fatigue syndrome, asthma, thyroid gland. They all have a huge impact on the quality of life, darken our prospects for future. Alcohol, drugs, smoking have also become the reality of our life, especially among young and middle-aged people. Today we'll read the texts about the diseases which have come as a result of people's ignorance and lack of healthy habits.
Smoking
Smoking is very dangerous. Most young people smoke because their friends pressure them to do so. They may be copying their parents who smoke, or other adults they respect. At one time this would have been accepted as normal. But in the past 30 years attitudes about smoking have changes. Smoking is now banned in many places so that other people don't have to breathe in smokers' shocking tobacco smoke.
Passive smoking, when you are breathing someone else’s smoke, can damage your health just like smoking can. Smoking becomes addictive very quickly, and it's one of the hardest habits to break.
A chemical called nicotine is a substance that causes addiction. It is a stimulant that increases the pulse rate and a rise in the blood pressure. Cigarette smoke also contains tar - a major factor for causing cancer.
Chronic bronchitis occurs when tar and mucus damage the air sacks in the lungs. The sufferer has a bad cough which is worse in the mornings, and may get breathless easily.
Gases in cigarette smoke increase your blood pressure and pulse rate. This can contribute to heart disease. Smokers as twice as non-smokers are likely to have heart trouble.
Smokeless tobacco that is chewed rather than smoked, is also harmful, causing mouth sores, damage to teeth and cancer.
If you've ever watched an adult trying to give up smoking, you know how hard it can be. It's easier, healthier and cheaper never to start.
Facts about smoking
Alcohol
Another poison of many young people is alcohol. Remember, alcohol is a drug. It can make you sick, and you can become addicted to it. It's a very common form of drug abuse among teenagers.
Alcohol drinks are made up chiefly of water and ethanol, which is an alcohol produced by fermenting fruits, vegetables or grain. Beer is about one part ethanol to 20 parts water. Wine is stronger, and spirits are about half ethanol and half water.
Alcohol is a drug. In fact, it is a mild poison. It is absorbed quickly into the bloodstream, within 4 or 10 minutes of being drunk. Absorption is slower if there's food in the stomach. Once inside the body it passes through the bloodstream to the liver, where poisons are digested.
But the liver can only process 28 grams of pure alcohol each hour.
This is a small amount - just over half a glass of beer. Anything else you drink is pumped round the body while it waits its turn to enter the liver.
When alcohol reaches your brain, you may immediately feel more relaxed and light-hearted. You may feel you can do crazy things. But after two or three drinks, your actions are clumsy and your speech is slurred. If you over-drink, you might suffer from double vision and loss of balance, even fall unconscious, hangover.
Drugs
In facts, all medicines are drugs. You take drugs for your headache or your asthma. But you need to remember that not all drugs are medicines. Alcohol is a drug, and nicotine is a drug. There are many drugs that do you no good at all.
There's nothing wrong with medicinal drugs if they're used properly. The trouble is, some people use them wrongly and make themselves ill. Most of the drugs are illegal, but some are ordinary medical substances that people use in the wrong way.
People take drugs because they think they make them feel better. Young people are often introduced to drug-taking by their friends.
Many users take drugs to escape from a life that may seem too hard to bear. Drugs may seem the only answer, but they are no answer at all. They simply make the problem worse.
Depending on the type and strength of the drug, all drug-abusers are in danger of developing side effects. Drugs can bring on confusion and frightening hallucinations and cause unbalanced emotions or more serious mental disorders.
First-time heroin users are sometimes violently sick. Cocaine, even in small amounts, can cause sudden death in some young people, due to heartbeat irregularities. Children born to drug-addicted parents can be badly affected.
Regular users may become constipated and girls can miss their periods. Some drugs can slow, even stop the breathing process, and if someone overdoses accidentally they may become unconscious or even die.
People who start taking drugs are unlikely to do so for long without being found out. Symptoms of even light drug use are drowsiness, moodiness, loss of appetite and, almost inevitably, a high level of deceit.
First there's the evidence to hide, but second, drugs are expensive and few young people are able to find the money they need from their allowance alone. Almost inevitably, needing money to pay for drugs leads to crime.
