1. Importance of Health

Existence is the rule of the Universe.

Fight for existence is the rule of nature .

Human life can exist only if other life exists.

Health of whole life is important for existence.

Protect other life to protect your life.

So protect your health to protect other life.

The ultimate goal of human beings is to lead a HAPPY LIFE. To achieve this, human beings formulated many diverse principles depending on individuals thinking and society needs. The ultimate aim of every religion, every culture and every social custom is to develop healthy and happy society comprising of individuals. Here, an effort is made to suggest a scientific way of leading a healthy and HAPPY LIFE, which can be achieved by individual effort.

Health is Wealth. This is a well known wise saying. Everybody likes to lead a happy life. Good health is the first and foremost basis of happy life. From birth to death we are governed by our fate. Keeping healthy is in our control and that is the primary source of happiness.

2. What is Health?

Health has got three dimensions and can be depicted by the so called HEALTH TRIANGLE and is defined as physical, mental and social well-being. (See Figure 1)

Health is not a natural gift and it is to be achieved by constant effort. Health cannot be gifted, stored or cannot be stolen. Health cannot be exchanged or borrowed. Healthy status is not a one-time achievement. It is the result of constant effort to keep our body fit and healthy. A healthy person is an asset to society and is liked by everybody. One’s health is not source of hate or jealousy; but one’s ill health is. An unhealthy person is a burden to society and is disliked by others.

3. Life and Health

Life always starts with a single cell. Life is the ability of the cells to regenerate and multiply. Our body starts as a single cell and multiplies in different types of cells to make our body perfect and complete as an organism to function. The structure of our body is decided by the genes, which are inherited from our ancestors. The genes control each cell of our body. Human beings are an intelligent form of life, which can visualize this universe, can appreciate the creation of the universe and can enjoy the nature.

Without human beings this creation is incomplete (All forms of life are important for the Earth’s biosphere to function in an ecological balance).

4. Structure and Function of the Human Body.

Human body is made up of billions of cells, which are always active and need energy for their survival. Activity within the cells is called metabolism. In the process of metabolism the cells produce metabolites or waste products, which are to be regularly drained. These impurities produced in our body are drained through eight drainage channels, the proper function of which is highly important. Our body comprises of many internal and external organs, 206 bones, 640 –800 muscles, 230 - 260 joints, countless ligaments and tendons. It has got countless nerves, billions of neurons, millions of blood vessels and capillaries. Survival and proper functioning of all the above structures need energy and energy is provided by nutrients. Distribution of nutrients to the cells depends on proper circulation of blood to all parts of the body.

5. Blood Circulation in our Body.

Our body is full of blood vessels and countless capillaries spreading to every part of the body. Under normal conditions these capillaries mostly are collapsed and no blood flows through them. Only 10 –15% of capillaries are open supplying the blood to the tissues. In inactive and lazy people more blood vessels and capillaries are collapsed and body circulation is much more diminished leading to various diseases. So it is important to keep our body active and free from diseases by activating our circulatory system to fight effectively against diseases.

6. Ten Secrets of Healthy Living.

6.1. Balanced food and drinking clean water
6.2. Adequate rest and sleep
6.3. Proper body posture
6.4. Prevention of disease (vaccination and precautions)
6.5. Abstinence from smoking and drinking
6.6. Exercises and Yoga
6.7. Early treatment of disease
6.8. Positive thinking
6.9. Breathing and meditation
6.10. Social well-being

Disease cannot be prevented altogether. Increasing our body defense can minimize the severity of a disease and fast recovery can be ensured. To increase our body defense is within our control.

7. Exercises and Yoga.

Why the exercises are important for our body?
One of the most important secrets of keeping good health is body exercise. Regular exercises make our body active and keep the diseases under control. Human beings are physically the weakest of all creatures on earth. They need external support to keep their body safe and out of danger and through their intelligence they create many artificial things for safety, health and happiness, where as other creatures are naturally provided with various defense systems to protect their bodies and secure their food and safety. Other creatures do not cultivate food, store food or depend on others for their daily needs. They have themselves to search for food and defend themselves through self defense mechanisms. So they are always physically active and go through natural exercises. So they do not need additional exercises to keep their body active and vigorous.
Besides that animals know what to eat and what is fit for their body. They do not eat what is not good for their health and safety. They don't drink or smoke. They can detect poisonous foods by smelling them and avoid eating them. In this way they protect their bodies and remain comparatively healthier than humans. Hence animals are indirectly doing exercises to keep their body fit and healthy and they have high digestive power as they do not cook foods and consume natural raw foods. It means that natural foods are healthier than artificial and junk foods.
Even in human beings up to certain age nature acts to force us to undergo physical activity in natural way. After fertilization the fertilized egg has to travel a long distance before gestation. In the mother's womb the fetus is always moving and limbs are actively stretched and flexed and Mother feels the fetus movements and gets worried if the fetus is not hitting the mother’s womb. After birth the newborn baby suddenly gets stimulated and cries and moves body vigorously. Babies constantly and vigorously move their limbs and make several gestures from the time of birth itself. Small children try to run, play and try to keep themselves physically active by doing all sorts of movements in the home and parents are sometimes worried about their children without knowing that it is nature’s way of keeping the children healthy and promote their growth. Young children are always keen to play and keep physically active. All this is nature’s way of keeping our body active and forcing the body to do natural exercises to keep healthy and promote normal growth in children.
Nature takes care of our body before we realize the importance of exercises. As we grow it is left to our choice to do exercises and to keep our body healthy and active. Every body knows that it is important to keep healthy and health is a source of happiness. But how many are working in this direction to follow the nature’s rule to keep fit? Here it should be stressed that that in humans, nothing comes naturally except eating and drinking, without learning. We have to learn everything to perform our tasks in beneficial ways; so also the exercises. Exercises are to be learned to perform in a systematic way for the beneficial effects on our body, mind and thereby health. 

Why we become sick and suffer? 

It is a vast subject. It is very difficult to go into full details. But a brief explanation is given below. Our life is supported by nature around us. Nature is created to support life on earth and more so the human life. Without other life on earth human life cannot exist. But without Humans all other life can exist. Human life is created after all other creation is perfected. Till now human life is the latest form of life in the process of evolution of the various life forms. 

Why human life cannot exist without other form of life on earth? Life started on earth with formation of single cell organisms. That is the first step in creation. Next step is two cell organisms. In this way life is built up step by step to the present form of vertebral species – the humans. Every step is supported by the step below. If the first step that is the single cell organisms perishes from earth the bottom foundation is gone and all other steps( forms of life) collapse and life vanishes from our planet. Because 1st foundation step is support for upper steps. In each step there may be several types of organisms. If some organisms in that step perish it may not affect much. If all the organisms of one step perish the steps above will collapse. Suppose first step single cell organisms perish on earth whole life on earth will perish. So life on earth depends on one on another. Earth’s biosphere is a grand “society” of living things-plants and animals, in which life forms live in an ecological balance which is essential for life to sustain. Why so?

How the exercises can help to promote our health?

There are several ways that the exercises and yoga help our body to keep healthy and fast recover from illness. Exercises need supply of energy and supply of energy is possible through good blood circulation. So good circulation in the body is possible through opening of the already closed vessels. Hence the capillaries, which are mostly collapsed during sedentary stage of our body will open up and improve circulation to meet the energy needs of active body. Improved circulation of the body tissues promote the regeneration and drainage of accumulated impurities and make the body tissues healthy and vitality of the tissues. If the tissues are healthy they fight against the disease producing forces and keep the body healthy. Our body constantly fights against micro-organisms which are all around us and try to attack our body. Our body’s defense mechanism to defend our body, from disease producing external forces, will be improved by body exercises.

Micro-organisms which are all around us,on one way support our life on earth by clearing the poisonous materials in our climate, and on another way attack our body in a harmful way to generate disease in our body tissues. So it is our body which has to develop immunity against the disease. So the exercises do this job by improving the circulation and providing energy needs of our body to defend against disease producing forces..

8. Differences between Normal Body Exercises and Yoga Exercises. 

What is Yoga?

There are many differences between normal physical exercises and Yoga exercises.

Most important differences are mentioned below.

9. Benefits of Body Exercises and Yoga.

Benefits of Yoga exercises are plenty. To explain mechanism of each benefit is very lengthy process. Benefits are well explained wherever necessary. In general the benefits are achieved through meeting the energy requirements of the body tissues by effective blood circulation and timely removal of toxic materials from the body cells.

9.1. Regulate the sleeping mechanism- Sleep and relaxation is most important factor for healthy life. Irregularity of sleep is a common problem. Sleep is affected      through accumulation of toxic chemicals in the brain which are effectively drained through exercises and mental relaxation.

9.2. Activate  our mind's biological clock and inform us about what is to be done at what time. By activating biological clock, so many daily activities are time bound,sleep, hunger, mental alertness ( working time) and even exercise time is set and we get mental alarm at exactly same time every day if the biological clock is set properly. We do not need alarm clock if we strictly follow the mind's biological clock.

9.3. Control the restless leg syndrome, which is the most common problem in the present society.

9.4. Control the restless night syndrome – Here people suddenly wake from sleep and feel disturbed and become restless for hours and do all sorts of efforts to sleep again. But they do not get sleep for long time.

9.5. Exercises improve the range of joint movements by effectively stretching the joint ligaments and increasing the ligament elasticity, strengthening the ligaments to their maximum capacity. Ligament stretching and strengthening of ligaments prevent from injuries of joints and occurrence of fractures to a great extent.

9.6. Muscle strength is improved by full contraction of muscles and stretching of muscles during exercises. Strong muscles are needed for our healthy and happy living.

9.7. Regular exercises strengthen the heart function by improving its circulation and formation of flakes in the heart vessels is prevented.

9.8. Not only the joint ligaments but all other ligaments of our body are stretched and strengthened.

9.9. Tissue perfusion is improved and timely tissue repair is undertaken.

9.10. Regulate digestive system, improve the digestion, increase appetite, reduce acidity and promote regular bowel function.

9.11. Improve the function of internal organs like liver, spleen, pancreas, kidneys and other internal organs (endocrines) by massage like effect on these organs by certain special exercises so that sluggish organs get stimulated and function well.

9.12. Reduce the dosage of medicines by improving the absorption of medicine and distribution of the medicine to cells by improved perfusion of the cells. So the dosage of medicine in many chronic diseases like diabetes and hypertension can be reduced to half by regular yoga.

9.13. Effectively overcome disuse atrophy of muscles and in bones and joints in degenerative joint diseases like joint pains, osteoarthritis, osteoporosis and other joint diseases.

9.14. The exercises may not totally prevent diseases but can protect and fight against the disease producing micro organisms and natural forces by timely response of the body defense mechanism.

9.15. Promote the effective repair of the tissues after injury or disease and aid early recovery.

9.16. Increase the body resistance by promoting healthy external organs like skin, ears, mouth, nostrils and eyes.

9.17. Rejuvinate body and aging process of the tissues and brain will be delayed and person looks younger.

9.18. Improve the mental performance, increase memory and activate mind of right judgment and quick decision-making.

9.19. Calms the mind and reduce anxiety, fear, and depression and reduce the ill effects of chronic illnesses like hypertension, diabetes and many other diseases.

9.20. Generate positive thinking and lead to realization of self and meaning fullness of life .

So exercises should be part and parcel of our life. Our concentration is focused not on physical body exercises meant for body building but on yoga exercises which are meant for long term health of every part of the body and personality development. Here the subject is focused on all body health and also prevention and cure of each part of the body like joints, muscles, ligaments and internal organs. Here suggestions are made on individual needs depending on how much time they can afford each day for their body fitness and how to overcome disabilities of each part of the body by yogic exercises along with medical treatment. These yogic exercises should be performed in a systematic way to get maximum benefits and should be carefully observed and learned before practicing.

Before starting daily yoga exercises a basic routine should be followed.
