Lesson 11

  1. 1. 11 Concept of Health 11.1 Introduction You must have heard your mother, your grandparents, in fact, most elders, say- ing that if you want to remain healthy, you must follow certain rules. There are certain things you are asked to do everyday like brushing your teeth, having a bath, eating good and nutritious food at regular times, sleeping early and getting up early and doing regular exercise, etc. Have you ever asked yourself why you are told to do all the these things? What will happen if you do not bathe daily? What will happen if you sleep late every day? What will happen to your body if you do not take nutritious food? Can you imagine what your body will start looking like if you just kept on eating and do nothing? How can you find out whether you are healthy or not? What are the signs you would look for? These are some of the questions that will be answered in this lesson. 11.2 Objectives After reading this lesson, you will be able to the following: define ‘health’; describe the physical, mental and social aspects of health; list the indices of good health; explain the importance of health; relate prevailing conditions to their consequences.
  2. 2. 164 :: Home Science 11.3 Concept of Health There are a number of things you want to do, but there are times when you find that you are not well enough to do all that you want to do. Even on a regular morning, when every member of the house is getting ready, there is so much to do - someone wants breakfast, your sister wants her shirt to be ironed, your little brother realizes that his shoes are not polished. Your mother is trying to cope up with everything. You want to share some responsibilities with your mother, but you do not have enough energy to do so, because your body is so weak that it can not take extra stress. This shows that your body can function effectively only when it is healthy. Definition of health You may say ‘health’ is the absence of disease. According to the World Health Organization, “Health is a state of complete physical, mental and social well being and not merely the absence of disease.” Can you now list the signs of good health? Also, can you tell why this listing is necessary? Yes, you are right. If you know the signs of good health, you can recognize a healthy person, or know if you yourself are in a state of health. Let us study the signs in detail now. 11.4 Signs of Good Health To look for signs of good health, we must examine all the three aspects-physical, mental and social. A. Physical health Physical Mental A person who enjoys good physical health is one who - is energetic Social has good posture weighs normal for age and height has all body organs functioning normally has a clear and clean skin has bright eyes has good textured and shining hair has a clean breath has a good appetite gets sound sleep
  3. 3. Concept of Health :: 165 Physical health is easy to detect and describe. A person is physically healthy if he or she looks alert and responsive. B. Social heath A person with good social health - gets along well with people around has pleasant manners helps others fulfills responsibility towards others A person is socially healthy if he or she can move in the society confidently with others. C. Mental health Mental health implies - control on emotions sensitive to the needs of others confidence in one’s own abilities freedom from unnecessary tensions, anxieties and worries A person is mentally healthy if he or she is relaxed and free from any wor- ries PHYSICAL, SOCIAL AND MENTAL HEALTH ARE INTER RELATED You would be surprised to note that all three aspects of health are related. Have you noticed that when your brother has been through an illness, he becomes irritable? He loses his temper much faster than in his healthy days. Why? He lacks in physical energy and gets frustrated when he can’t do things that he wants Physical health Aspects of Good health Social Mental health health
  4. 4. 166 :: Home Science to do. Hence he gets angry, cries, shouts, screams and fights. Have you heard of cases where people develop high blood pressure because they worry too much or develop ulcers in the stomach because they are tens all the time? Hence, you can see that a change in any one aspect of health, that is social or mental or physical, has an effect on the other aspects also. All the three aspects are inter–related and to be called healthy, one must have good health in all the three aspects. INTEXT QUESTIONS 11.1 1. Choose the correct alternative: (i) A person is healthy if he is - (a) Physically and mentally healthy (b) Mentally and socially healthy (c) Physically and socially healthy (d) Physically, mentally and socially healthy. (ii) A mentally healthy person has - (a) Confidence (b) Energy (c) Pleasant manners (c) Good appetite 2. State whether the following statements are true (T) or false (F) (a) Health means absence of disease (b) A physically healthy person has well functioning organs in the body. (c) Freedom from tension implies good mental health. (d) If a person helps others it is a sign of social health. 3. State four characteristics of a person enjoying ‘Good health’. 11.5 Factors Affecting Health In the beginning of the lesson, we talked of a few things which your elders ask you to do everyday. Do you remember what they are? These are some of the things which affect your health. If you do them you remain healthy.
  5. 5. Concept of Health :: 167 Let us now study all the factors which can affect our health - (1) Personal hygiene (2) Exercise. (3) Rest and sleep (4) Posture (5) Clean home environment (6) Our eating habits (7) Climate and clothing (8) Safety measures at play and work (9) Influence of smoking, alcohol and drugs Let us now examine some of these in detail. 11.6 Personal Hygiene Personal hygiene means keeping oneself clean. There are some activities you perform everyday in order to keep yourself clean. Can you list these? Yes, some of these are going to the toilet, cleaning your teeth, having a bath, cleaning your eyes, washing your hands before and after eating, wearing clean clothes, combing your hair, etc. You must realise that all these are the rules of personal hygiene. 1. Regular use of the toilet: Why does your mother insist that you go to the toilet every morning? Because a regular bowel movement keeps your body free from waste matter. You probably have a toilet at home. But there are many people who do not have it. They have to go out to the fields to defecate. Here are some things you must remember when using the toilet. (a) Always wear shoes- Wearing shoes when going to the toilet is necessary because germs and dirt will not stick to your feet and make you ill. (b) Use clean water in a clean mug- Always use clean water in a clean mug to wash yourself after going to the toilet. Dirty water carries germs and is harm- ful for you. Can you say what will happen if you carry clean water in a dirty mug? The water will also become dirty. So, make sure to use clean water in a clean mug. If you scrub your mug everyday with a cleaning powder it will stay clean.
  6. 6. 168 :: Home Science (c) Wash hands after toilet- Make sure to wash your hands with soap and not mud after going to the toilet. Why is this necessary? This is necessary be- cause the dirt and germs on your hands must be removed. While washing hands see that your nails are also cleaned. Imagine what will happen if you eat food with these dirty hands! Why should you not use mud to wash your hands? Because mud may contain dirt and germs which can cause disease. 2. Washing hands before eating: When you eat with dirty hands, you also eat the dirt. This dirt is full of germs which can cause diseases. This is why, your mother always asks you to wash your hands with soap and water before you eat anything. 3. Bathing regularly: ‘Bathing’ does not mean that you simply pour water on your body. Taking a good bath means that you should thoroughly apply soap on the entire body. Also after taking a proper bath, it is very important that you use a clean towel to dry your skin. Otherwise, your skin would again become dirty if you do not use a neat and clean towel to wipe your body. Examine your skin carefully. Can you see very small holes in your skin? These are called ‘pores’ and your skin breathes through these pores. When dirt collects on the skin, these pores get blocked. Germs attack, and the result is pimples and boils. Hence, to avoid all these diseases and skin infections, it is necessary for you to have bath regularly, and keep your skin clean in sum- mer as well as in winter. 4. Brushing your teeth: Have you ever stood near a person with bad breath? Don’t you feel like turning your face away? What do you think causes bad breath in a person? Bad breath is caused due to unclean teeth. When teeth are not brushed regularly, small bits and pieces of food stick to them. Germs like bacteria come and attack this food and the teeth at the same time. Soon the teeth lose their shine, become yellow and the breath begins to smell. Do you understand now why it is important for you to brush your teeth regu- larly? You must remember that for brushing you should use a proper brush which is soft and do not hurt your teeth and gums. For proper care of teeth, it is very important that after every meal, you must wash your mouth with plain water. This would prevent decaying of teeth that is, your teeth would remain healthy. Sweet foods are more harmful than salty foods. This is why your mother tells you not to eat too many things like sweets, chocolates, ice creams, past- ries, etc. Drinking plenty of milk helps in making your teeth strong and healthy.
  7. 7. Concept of Health :: 169 5. Washing hair, cleaning eyes, ears, nails: Have you noticed what happens to your hair when you don’t comb them for a day? There are tangles in them and combing is difficult. If you don’t wash them for a few days, your hair becomes dirty and dull. It may also get infested with lice. To avoid all this, you should comb your hair daily and wash them frequently to keep them shining and smooth. What happens when you don’t wash your eyes? Dirt collects in the corners and makes them sticky. Flies come and sit on this dirt and cause infection. This infec- tion makes you rub your eyes which causes redness. Wash your eyes regularly with clean, cold water and keep them shining and clear. Your ears become blocked with a yellow wax which must be removed. Blocking can cause deafness, hence, wax must be removed. Be careful in removing wax. Never use pointed pins to remove it. Your ear drum may be hurt. Do not put any oil without consulting the doctor. Long nails gather a lot of dirt under them. Have you seen how dirty your nails look when dirt has collected under them? This dirt can have germs and can enter your stomach along with your food. You know that the germs can then make you ill. Therefore, what should you do? You should keep your nails short and clean. INTEXT QUESTIONS 11.2 Complete the sentence with the correct word: 1.

  8. 8. 170 :: Home Science ACTIVITY Select ten children in your neighbourhood. Observe their nails, teeth, hands, hair, clothes, shoes, etc., and find out how many of them are clean. Record this information in the format given. Name Nails Teeth Dress Hair Clothes Shoes Cut clean washed clean washed polished 1.Ritesh √ √ √ √ √ √ 11.7 EXERCISE Suppose you decide to clean your kitchen and store on the same day. How do you feel after doing all the heavy work? You feel very tired, your whole body and specially your arms ache and pain. Why is this so? This is because you have used those muscles of your body which you generally do not use. These muscles are not used to exercise and, hence, start aching. Exercise means making all the muscles of the body work so that they re- main fit and active. In order to be beneficial, exercise must be - systematic regular adequate, that is, neigther not too little, nor too much. It is important to remember that sick and weak people should not do strenuous exercises which may make them sick. You already know that extra fat is stored in the muscles of your body. Exercise helps to remove this fat. Can you imagine how fat you will become if this fat is not removed through regular exercise? During exercise, all the organs of the body start functioning efficiently. Have you noticed how your legs start tingling after you come back from a walk? Do you also feel hungry after exercise? Exercise makes you active physically and mentally, and ready for work. Can you now say, why exercise is important for us? Yes, exercise is important because it:
  9. 9. Concept of Health :: 171 helps to reduce body fat ensures better digestion and respiration ensures efficient blood supply increases mental alertness adds to physical mobility makes one feel more energetic What do you think is the best way to exercise? You can- play any game you like go swimming go walking or jogging do yoga, etc. You can choose any exercise, depending on your interest. Exercise can be done either in the morning or in the evening, depending on your convenience. But remember the best time for exercising is early morning. Because this is the time when the air is fresh and free from pollution. When you breathe this air, you feel very fresh throughout the day. 11.8 Rest and Sleep Although regular exercise is essential for the upkeep of health, regular rest and sleep are equally necessary. This is for the tired muscles to relax. Do you remember what happens after you wash a lot of clothes in a day? Your arms start aching and you feel very tired. At that moment, you feel you cannot do any more work. But after sitting for some time, you feel fit and start doing some- thing else. When you work, your body uses oxygen which gives you energy. When this oxygen is used by the body, some waste products are produced which collect in the muscles. Normally, these waste products are removed as soon as they are formed. But when you do heavy work, these waste products are formed faster than they are removed, so they start collecting in the muscles. As a result you feel tired. This tiredness is also known as “fatigue”. ‘Fatigue’ is the body’s inability to do further work or it is the body’s reduced capacity to do work. When you sit down and rest, your body finds the time to clear this waste and your muscles become active once again. Similarly, sleep not only relieves your tired muscles but also your mind.
  10. 10. 172 :: Home Science Work Refreshed Tiredness Rest and Sleep Every one does not need the same amount of sleep. You have seen that small children and babies sleep more than you or your parents do. A person who works hard the whole day, will also need to sleep more than one who does little work during the day. Can you tell why? 11.9 Posture Have you noticed that some people walk and sit with their back straight and some others walk with their backs bent? Which do you think looks better? The straight back or the curved back? Yes, the straight back looks much better and is also the correct way to walk and sit. The manner in which one sits or walks is known as posture. If you do not hold the body properly when standing or sitting, your posture is incorrect. If you stand or sit with your back bent, it will put extra pressure on the organs of your abdomen and chest. You will also develop a curved spine which will result in backache. So you can see why maintaining a correct posture is important if you want to remain healthy? Remember, correct posture is not only important while sitting, walking or stand- ing. It is equally important that while doing any household task, one must have good posture. Do you know what is a correct posture? ‘Correct posture’ in doing any task may be defined as the position which requires the utilization of the smallest amount of energy. For example, a correct standing posture is the one in which the head, neck, chest, and abdomen are balanced vertically one upon the other. ACTIVITY In your family, make a note of all the members who have improper posture while sitting at a desk or while walking. Recommend to them the right way of main- taining good posture.

  12. 12. 174 :: Home Science 11.10 Clean Home Environment A clean and healthy environment around you does a lot in keeping you in good health. You have already learnt how to keep your environment clean in lesson 10. It would be helpful to go back and read that lesson once again. 11.11 Our Eating Habits The food we eat can affect our health in many ways. So it is very important to know which foods to choose and why. All of you know food is very important for us. Food is required:- (a) provide energy in our body (b) build muscles and bones (c) protect the body from diseases It you want to be healthy, you must eat proper food which is balanced and pro- vides you with all the nutrients. If you look around, you will find that many children are thin and small and may be very weak. Do you know what would be the reason for this? All these may be due to the fact that: (a) They do not eat the right kind of food (b) They have poor eating habits Apart from eating the right kind of food, it is important for you to develop good eating habits. These are: (1) Eating the right quantity of food (2) Eating food at proper times (3) Avoiding snacks between the meals (4) Keeping a check on too much of fried or fast foods (5) Eating more fruits and vegetables (6) Avoiding sweets, chocolates, etc. 11.12 Climate and Clothing You have already studied about clothes and the need for clothes in lesson 8. If you like, you can go back and read it once again. You know that clothes are made of various fabrics which are suitable for different types of climate. It is very important for us to select the right kind of clothes to wear according to
  13. 13. Concept of Health :: 175 the climate, otherwise we will be uncomfortable and this may also affect our health. For example, if one wears woolens in summer season, one will develop rashes on the skin. Similarly, if one wears light, cotton clothes in winter, one may catch a cold and suffer. Similarly, if the clothes worn are not clean or according to the prevalent fashion, the wearer feels conscious. It generates a feeling of inadequacy or inferiority. This will affect the manner of working of that person. The following tips can help you: You can be comfortable by wearing cottons in summer and silk or woolens in winter. You will find synthetic or non-crushable fabrics more suitable for office or long time wear. Festive occasions call for bright colours whereas hospital visits and funer- als call for softer shades. Remember, even though you may not have many clothes, you can still be smart and well dressed if you keep your clothes clean and well pressed. You can also mix and match your clothes to get different combinations. 11.13 Safety Measures at Play and Work You know that safety has a direct influence on your health. If the environment around you is not safe, your health will immediately suffer. If floors are slippery or stairs uneven, or the roof top has an unprotected edge, there may be accidents. You will study more about safety measures to be taken at home and the conse- quences of not observing safety measures in lesson 29 in this course. We can say that in order to maintain a healthy life, one must take precautions every where - at home, in the play ground, on the roads, at work, etc. 11.14 Influence of Smoking, Alcohol and Drugs SMOKING Smoking is a habit. It does the most harm to your body, whether it comes from pipes, cigars or cigarettes. It is due to the harmful carbon monoxide and nicotine. They damage many different parts of the body. When people first smoke (breathe the smoke into their lungs), their eyes start watering and they may cough. It is very important to break this habit. Continuous smoking become a cause for cancer of the lungs and mouth. It also makes a person prone to heart diseases and heart attack.
  14. 14. 176 :: Home Science ALCOHOL Like smoking, drinking alcohol becomes a habit. Although young people start drinking under peer pressure, they soon become addicted to it. Alcohol slows down working of the brain. As a result, the person becomes disoriented or con- fused. Excessive consumption of alcohol can delay responses. This is why people under the influence of alcohol are not permitted to drive. Alcohol consumption leads to hardening of arteries and may result in heart at- tacks. Thus, drinking is a habit everyone must avoid at all costs. DRUGS Drugs are the medicines used to cure illness, reduce pain and prevent the spread of disease. Drugs have been used for thousands of years. There are many sources from which they are obtained–basically, they come from chemicals in the roots, leaves, seeds and juices of plants. Drugs are beneficial to us when taken in the prescribed dosage only. When over- doses of certain drugs like cocaine, morphine, are taken, the person becomes addicted to them. Over a period of time, this may prove fatal and the person may die. INTEXT QUESTIONS 11.4 1. If you want to be healthy, you must eat: a) Fried food b) Chocolates, in addition to food c) Meals at regular time d) Meals at odd hours 2. Indicate the kind of clothes most suitable for wearing in- i) Summer __________ ii) Winter ____________ iii) Rainy season ___________ iv) Weddings ______________ 3. State two ill-effects that smoking can have on a person’s health. 4. What can be the consequences when a person under the influence of alchol drives a car? 5. State one benefit of taking drugs. 6. What can happen to a person addicted to drug use?
