Gr10 lesson3

  1. 1. ALCOHOL
  2. 2. What is alcohol? <ul><li>Alcohol is created when grains, fruits, or vegetables are fermented . Fermentation is a process that uses yeast or bacteria to change the sugars in the food into alcohol (ethanol). </li></ul><ul><li>Fermentation is used to produce many necessary items — everything from cheese to medications. Alcohol has different forms and can be used as a cleaner, an antiseptic, or a sedative. </li></ul><ul><li>Ethyl alcohol, or ethanol, is the intoxicating substance in beer, wine and liquor. </li></ul>
  3. 3. How Does It Affect the Body? <ul><li>Alcohol is a depressant , which means it slows the function of the central nervous system. Alcohol actually blocks some of the messages trying to get to the brain. This alters a person's perceptions, emotions, movement, vision, and hearing. </li></ul><ul><li>In very small amounts, alcohol can help a person feel more relaxed or less anxious. More alcohol causes greater changes in the brain, resulting in intoxication . </li></ul>
  4. 4. <ul><li>People who have overused alcohol may stagger, lose their coordination, and slur their speech. </li></ul><ul><li>They will probably be confused and disoriented. </li></ul><ul><li>Depending on the person, intoxication can make someone very friendly and talkative or very aggressive and angry. </li></ul><ul><li>Reaction times are slowed dramatically — which is why people are told not to drink and drive. </li></ul><ul><li>People who are intoxicated may </li></ul><ul><li>think they're moving properly when </li></ul><ul><li>they're not. They may act totally </li></ul><ul><li>out of character. </li></ul>
  5. 5. <ul><li>When large amounts of alcohol are consumed in a short period of time, alcohol poisoning can result. Alcohol poisoning is exactly what it sounds like — the body has become poisoned by large amounts of alcohol. </li></ul><ul><li>Violent vomiting is usually the first symptom of alcohol poisoning. Extreme sleepiness, unconsciousness, difficulty breathing, dangerously low blood </li></ul><ul><li>sugar, seizures, and even </li></ul><ul><li>death may result. </li></ul><ul><li>This is also known as </li></ul><ul><li>Acute Alcohol Intoxication . </li></ul>
  6. 6. Dangerous Levels of Intoxication <ul><li>Not everyone who goes to sleep, passes out or becomes unconscious after drinking has a high Blood Alcohol Concentration (BAC). People who are already tired or bored may doze off after very little alcohol. </li></ul><ul><li>However, people who drink heavily in a short period of time are risking their lives, because a high BAC can result in Acute Alcohol Intoxication (alcohol poisoning). </li></ul><ul><li>Acute Alcohol Intoxication Seek emergency help when the person who has been drinking heavily: </li></ul><ul><ul><li>cannot be awakened </li></ul></ul><ul><ul><li>has a weak, rapid pulse </li></ul></ul><ul><ul><li>has an unusual or irregular breathing pattern </li></ul></ul><ul><ul><li>has cool (possibly damp), pale or bluish skin </li></ul></ul>
  7. 7. Blood Alcohol Concentration (BAC) <ul><li>Blood Alcohol Concentration (BAC) is the amount of alcohol in the blood at any given time. </li></ul><ul><li>Blood Alcohol Concentration </li></ul><ul><li>BAC Level and it’s Effects: </li></ul><ul><li>.02 % to .03% People often feel very loose or relaxed </li></ul><ul><li>.04%-.05% Judgement, speech and motor coordination are definitely affected. </li></ul><ul><li>.08% to .10% Reflexes and judgement are clearly impaired. </li></ul><ul><li>.2% Could result in unconsciousness. </li></ul><ul><li>.3% Could result in a coma. </li></ul><ul><li>.4% to .5% Could cause death due to suppression of the brain's breathing center, the cerebellum. </li></ul>
  8. 9. Why Do Teens Drink? <ul><li>Experimentation with alcohol during the teen years is common. Some reasons that teens use alcohol and other drugs are: </li></ul><ul><ul><li>curiosity </li></ul></ul><ul><ul><li>to feel good, reduce stress, and relax </li></ul></ul><ul><ul><li>to fit in </li></ul></ul><ul><ul><li>to feel older </li></ul></ul><ul><ul><li>From a very young age, kids see advertising messages showing beautiful people enjoying life — and alcohol. And because many parents and other adults use alcohol socially — having beer or wine with dinner, for example — alcohol seems harmless to many teens. </li></ul></ul><ul><ul><li>See Handout on how advertising makes drinking seem acceptable! </li></ul></ul>
  9. 10. Why Shouldn't I Drink? <ul><li>Underage drinking is illegal. </li></ul><ul><li>It can make you do stupid or embarrassing things. </li></ul><ul><li>It puts your health at risk. </li></ul><ul><li>See the Handout on the Effects of Alcohol on the Body. </li></ul><ul><li>http://www.youtube.com/watch?v=tZmDWltBziM (drunk people) </li></ul><ul><li>http://www.youtube.com/watch?v=xH97OBRwC-A&NR=1 (alcohol abuse) </li></ul>
