Question: How do different types of books affect your heart rate? “I am doing a science fair project on how different types of books affect your heart rate. I am planing to have people read a paragraph or two of different types of books, and check there heart rate before, durring, and after. My teacher recomended that I ask you guys for information or helpful ideas on what else I should do. Thanks” Asked by Chelsie. Answer: The effect of reading books on the heart rate that I have presumed here, as the rate of heartbeat is pretty hard to tell as it involves a number of matters. I would like to put forward the possible factors involved before venturing into more details. 1. Mood of the subject. 2. Composition, clarity and versatility of the reading material. 3. Environment in which the experiment is taking place. 4. Inclination of the subject towards different topics or subjects in the reading material. 5. Beliefs and background of the subject. Now I shall discuss each cause in a bit more detail. Cause 1. The subject or the person who is reading the book can have different types of moods at the time when the experiment is conducted. Though it may be argued that a person’s mood can be judged by seeing his/her face, this may not be the case in all conditions. Besides a person himself cannot always describe his/her thoughts precisely. For example you might be feeling happy because you had a nice breakfast in the morning but you may suddenly remember last night’s scolding and can have a dual mood condition. Please note that the mood changes that we experience in our everyday life do not change the heart rate to a great extent unless of course it’s a critical case. Then how is that its going to effect your experiment. Well the acceptability of the material to that person depends on his mood and if is unable to accept the material, the experiment would be useless to perform. It’s like keeping an open book on your lap and dreaming about tomorrow’s football match. Cause 2. The composition of the material is also of utmost important. If it’s a boring material, the person will only be a passive reader which no effects on his mind and it turn no effect on his body. Here I would like to put the basic science behind the changes in heart rate or for that matter any physiological changes that occur when a person reads a book or watches TV. It is basic human nature that we always put ourselves in place of the protagonist. (Please note that this only happens when we put in our full concentration and attention). We become so involved in the material (TV show or book) that we almost begin to feel as if the things are happening to us. In other words, we get involved with the material. Considering that the person gets involved with the material, if the book is of horror he might feel a bit shivery. A very good example can be cited here. Suppose you sit for an exam and the moment you turn the question paper, you are sure that you are going to fail because you know none of the answers. What happens? Your hands begin to sweat and you feel chilly. The temperature goes down a bit. As you know we are homeothermals, so our body tends to maintain a constant temperature. Hence, the heart beat decreases and arterioles contract and the body tries to conserve heat. Coming back to the composition of the material if the material is hard to understand the degree of involvement of the reader would be minimal. In a recent research, it was found that uttering certain words can actually produce direct reactions in your body. In case of clarity or versatility the same holds. Cause 3. The environment is another important factor. Too much noise won’t help. You won’t get the chill of horror book if you read it in your school compound instead of reading it in a dark room with only a table lamp on. Cause 4. The subject should know a bit about the subject and should be interested in it. Like if you give me to read a history book, you will only be wasting your time measuring my heart beat. Cause 5. Its always advisable not to use religious books as beliefs and backgrounds vary from person to person and if that person does not comply with that subject , he won’t concentrate. As you must have understood by now, our main goal is to make the subject concentrate on the material. This may be easy for an avid reader but can be otherwise as well. Giving the subject to read one or two paragraphs to read won’t help much unless ofcourse the paragraphs are very interesting to him/her. Researches have been conducted on similar topics like relation of heartbeat to exercise. It is well known that if the material is very adventurous or exotic, a sudden rush of adrenaline may follow. Increasing heartbeat would complement this. The reaction again depends on the subject’s age and interest. So if you conduct the experiment, (provided that the reading material is greatly appealing to the subject) you will most probably get different results for different age groups and that too will effect from person to person. Well that about sums up everything I know about the topic. Since, you have asked for ideas, I would like to provide this. If I were in your place, I would have used a television or perhaps a computer instead of a book because seeing and hearing is more effective than reading. First, put the subject in a dark room with a projector. Measure his heartbeat (should be around 72 to 80 per minute) if he does not have low or high blood pressure. It is advisable not to take people with high blood pressure. Now play a slide show with different kinds of pictures (horror, funny, romantic, etc). Also, if possible, include some sounds with it. You will get different rates of heartbeat in each condition. You will also find that there is a gross difference in it for each age group. It is advisable that you take a number of people from each age group and sum up a total conclusion. By, Abhishek Dey Das. KV (AFS), Barrackpore, India. Website: http://deydas.co.nr.
