[Music] hi my name is Cassie in the next few minutes we are going to take a close look at some of the immediate effects of cigarette smoking to do that we’re going to use scientific equipment that will allow us to show smoking cigarettes can do to your body not twenty or thirty years from now but right now in a matter [Music] the instruments we’re going to use in our experiment are a pulse meter and a tremor tester I’ll show you how those work in just a few minutes now I’m sure you’re all aware of the long term effects of smoking you’ve heard that cigarette smoking has negative effects on many parts of the human body and that it’s a major risk factor for developing several types of cancer for example 90% of all cases of lung cancer occur in people who smoke cigarettes cigarette smoking also causes damage to the heart and circulatory system contributing to heart disease heart disease is the leading cause of death in the United States it is also the primary risk factor in respiratory diseases including emphysema and bronchitis it’s a fact that some of these diseases take a long time to develop sometimes 20 to 30 years so you may think that smoking isn’t really all that bad I mean after all why worry about something that could happen so far in the future right wrong because even though it may not seem like it when a person lights up there is an immediate impact on your body and particularly your lungs heart and central nervous system and we can prove it let’s talk about the immediate effect of cigarette smoking on your heart cigarette smoking causes your heart to beat faster this can be shown by measuring a person’s pulse it’s normal for everybody’s pulse or heart rate to change throughout the day in response to what your body needs any physical activity puts demands on the body to take more oxygen therefore there’s an increase in your heart rate when a person smokes the nicotine in cigarettes stimulates the heart to beat faster this increases the heart’s need for more oxygen the carbon monoxide in cigarette smoke replaces the oxygen in the blood forcing the heart to work harder to get the oxygen it needs these effects can easily be demonstrated by performing a simple experiment using a pulse meter an instrument that measures your heart rate to assist in our demonstration we’ve asked to smoker volunteers to help us John and Lisa first we use the pulse meter to get readings on John and Lisa before they smoke John will go first the towles meter tells us that John’s heart rate is 72 that’s 72 beats per minute now it’s Lisa’s turn her test results show her heart rate at 74 beats per minute now John and Lisa are going to step outside to smoke a cigarette when they’re finished we’ll test their heart rates again we’re ready to test our volunteers heart rates one more time and this time for John after smoking a cigarette the pulse from you two reads 121 that’s an increase of 49 beats per minute and for Lisa after smoking the reading is 125 and that’s an increase of 51 bits per minute smoking definitely accelerates your heart rate and an accelerated heart rate caused by smoking is not good for your body it puts an extra strain on your heart and reduces your endurance for physical activity as we’ve seen the nicotine in cigarette smoke acts as a stimulant we just saw in the pulse meter experiment how it increases your heart rate however the nicotine also affects another important part of your body your central nervous system you know lots of people think that smoking relaxes and calms their nerves in reality that’s not what happens at all as a matter of fact the exact opposite happens smoking tends to make people more nervous and again we can prove it this time by using something called a tremor tester the tremor tester consists of an impulse counter aluminum plate test probe in our demonstration we’re going to use the tremor tester to see whether smoking cigarettes really helps you relax or whether actually makes you more tense and nervous once again we’ve asked our smoker volunteers John and Lisa to assist with the demonstration before they smoke a cigarette they’re both going to take the tremor tester this is how it works all our volunteers have to do is hold the probe tip within the middle sized hole without touching the sides if they touch the sides they’ll complete an electric circuit and cause the meter on the impulse counter to move the meter keeps count as to how many touches they make the number of touches recorded in 30 seconds is the standard score let’s begin time is up and ELISA has got a score of 13 now let’s see how John does that was 12 touches now both Lisa and John will step outside to smoke another cigarette Lisa’s now ready to take the tremor test again let’s see how she scores Lisa’s hand shook much more after smoking her score went from 13 to 53 did smoking calmly sit down the answer is no let’s see how John does after smoking a cigarette John score went from 12 before smoking to 56 after smoking a cigarette once again demonstrating this smoking affects your central nervous system in a negative way so what did the results of the pulse meter and tremor tester tell us about cigarette smoking let’s review they both demonstrated that you don’t have to wait thirty ten or even two years for cigarette smoking to affect you the impact of cigarette smoking is immediate within seconds of lighting up your heartbeat increases dramatically the minute nicotine enters your body putting unnecessary physical demands on your heart and cigarette smoking doesn’t relax you instead it can actually make you more nervous that’s the truth about smoking cigarettes [Music] [Music]
