prevention 
Treatment is distressing, but prevention can be exhilarating. A lot of money is spent on treatment in a short time. But in prevention, a person spends money in a long time. Treatment is a waste of time. If prevention is at the disposal of the person himself and over time. Prevention is more accurate and easier. For example, prevention is possible by consuming fruits and vegetables, but treatment is done with expensive chemical drugs. Treatment is to affect a specific disease, but prevention can be to prevent several diseases. Prevention is a culture and treatment is a science. The culture of prevention is higher than the science of treatment.
Prevention is always more important than treatment. One of the reasons for the greater importance of prevention is that it prevents the imposition of exorbitant treatment costs and also helps prevent the spread of disease in society.
Also, another feature of the importance of prevention is that in prevention, the time required for training is short and the cost is low.
Because prevention is usually a less expensive measure, even sometimes it is free and very easy and more reassuring and only requires a little patience, but the treatment requires the use of drugs that are usually associated with side effects. You will experience pain and difficulty when you use treatment, during which you will have to stop doing many things in your life and wait for healing.
No one likes illness, and almost everyone rushes to specialists and treats the illness after feeling the slightest symptoms of illness and weakness. But why not do this when it is possible to prevent the disease before it occurs. The treatment of the disease certainly involves costs and makes the patient himself unable to handle daily tasks.
In Iran, patients are treated more than prevention and clinical control of health. Instead of needing the advice of a doctor and psychologist, people need his prescription drugs. Now, people's daily situation is moving towards fantasizing about health rather than ensuring longevity and life expectancy, because longevity is probably not beneficial for anyone and maybe the duration of the disease is more important. Unfortunately, in today's world, especially in our country, the competition to have a production market is more about treatment than prevention. As a result of prevention, which can prevent the spread of diseases by quickly transmitting information and awareness to the people with the occurrence of any kind of disease, it makes people need information at hand and to meet the need through the advice and advice of relatives and acquaintances. The lack of awareness causes May people's daily life be lived with fear of disease, and the last way is treatment by taking medicine and... This causes even insurance and other welfare institutions to not be able to provide extensive services to this huge flood of patients and lose money. Is it too much to expect that the essential part of health activities is to generate awareness for health promotion by people themselves in their daily life?

Adam Smith considered the hand of the market to be effective in guiding the society, and in this regard, we have to think about what causes the prevention and production of awareness to be replaced by disregarding the neglect of the people and the development of the treatment and medicine market. In such a situation, health turns into luck and people are constantly in fear and delusion, because they are not aware of their daily physical condition and remain more like cultural patients who always need doctors' bedsides to know about life and They are their own death. In previous years, various types of cancers, MS, various cold viruses, low-quality food products and contaminated with extra antibiotics, palm oil, etc. became common in our society, and its consequences are the loss of hope and quality of life in the society. to give But the invisible hand that thinks about the business of individualistic treatment is still ahead of its opponents, and with this state of society, it is unlikely that clinical treatment, prevention, awareness generation, health control of daily consumption and other types of health will reach him.

Today, the progress of human knowledge, despite the provision of comfort and well-being, has caused the occurrence of many physical and mental diseases and abnormalities, which imposes huge costs on governments every year, and due to the human need for rejuvenation and morale, the tourism industry is important. It is considered the most important factor in reducing these pains and restoring vitality and freshness to humans.
Health tourism is a new phenomenon in travel, nature and medicine, which is known in many countries and has been taken into consideration in the direction of the development and continuation of tourism. Man and environment are two words tied together and have spent a long history together. , and health and nutrition is one of the links between humans and the environment, which together with tourism brings health. Today, the desire of people to use natural resources and vitamins, to reduce pain, control stress and increase mental health is very impressive. Therefore, one of the most important subcategories of the tourism industry is medical tourism. Health tourism, which originates from the human need for treatment as well as the sense of nature-friendliness. On the other hand, the importance of tourism, especially in the field of ecotourism (nature tourism), has been revealed at the national and international level. In today's car-filled and busy life, humans need more and more connection with nature. In today's world, which is full of stress and anxiety, nature can rejuvenate the body and soul. 
Communicating with nature, listening to the sounds of nature, roaring streams, blowing winds, etc. can relieve the mind of all mental pressures. Getting used to nature evokes inner peace, and after that, man looks for the pleasure and the moment of happiness that he feels in his being. In practice and experience, it has been proven that leisure-leisure planning and design and the determination of human-environmental abilities is art and science, which is a mixture of information and techniques related to environmental architecture, the principles of environmental ecology and social sciences for the development of options. It is used for the purpose of using leisure time, space, energy and money (capital) in order to create adaptation and harmony and in a way that is compatible with the needs and wishes of people (tourists) (Mikaili, 2019).
