A passage on the modern life of man
An overview of industrial life in today's world The growth of urbanization and increase in population in recent years has caused cities to face a lack of space, and as a result, apartment living has an increasing growth. On the other hand, as a result of lack of space, green space has also decreased in cities. Many of us spend our working days in closed spaces, under the moonlight and in front of computers, after that we go home and relax our mind and body under the light of the TV screen. Daily city chores are exhausting. 
Man today is exposed to all kinds of pollution. Pollution is the presence or entry of one or more polluting substances or elements or a set of polluting substances and elements in the air, landscape or any other purpose in a continuous quantity and duration, which is harmful to humans, animals, plants and buildings. or harms people's comfort and property in a serious way, that environment is called polluted. This definition is almost close to the World Health Organization's definition of air pollution.

In general, pollution is divided into several main categories, which include: • water pollution • air pollution • Noise • Soil pollution • Magnetic pollution • Visual pollution 
All of us engage our mind in different issues during our daily life and we neglect our inner state. Often these daily routines and conflicts cause worry and stress in us and disrupt our peace. The first important thing to have mental health is to have peace. By having peace, you will progress in life issues, of course, we mean peace, an approximate peace that can be maintained over time and not having any worries. In the era we live in, it is not an easy task to eliminate all worries and concerns, but the important thing is that a person can evaluate himself and the situation and help reduce his stress, and if there is an unsolvable problem, he can deal with it and that to release him so as not to deprive him of peace. Mental health does not mean physical peace and lack of noise, but it has a more general meaning and the quality of life affects it. Mental health affects your daily thinking, feeling, and behavior, and it also affects your ability to face stress, overcome life's challenges, build relationships, and recover from hardships. Strong mental health does not mean that you don't have any problems, mental and emotional health is more than getting rid of depression, anxiety or other psychological problems. Unfortunately, among the general society, mental health is not as important as physical health, while mental health is an important issue that neglects and overshadows people's lives, because the degree of mental health in how they think, feel and act People have a role in facing different situations, so it is necessary to try to maintain and improve mental health as well as those who care about their physical health. On the one hand, mental health refers to having a sense of peace, security, and being away from anxiety, depression, and chronic mental conflicts, and on the other hand, it means benefiting from the health of the mind and thoughts. The direct relationship between physical health and mental health has made the benefit of mental health have a positive effect on physical health, and physical health provides a suitable platform for achieving a sense of inner security and mental and mental health.
What artificial environments take from man, nature returns to him. In the past, by creating open and green spaces and gardens in the inner space of Iranian houses, this importance has been provided, and in other words, the best possible view and view. has emerged
According to the definition of urban green space, it is a part of the urban open space, whose natural or often artificial areas are covered by trees, shrubs and bushes, flowers, grasses and other plants, which are based on human supervision and management, taking into account the rules and regulations. And related specializations are built to improve the living conditions and well-being of citizens. This is while the results of various studies show that the presence of green spaces can have positive effects on the residents of these spaces psychologically and physiologically. In principle, suitable green spaces in cities, in addition to physical health, cause mental peace, greater work efficiency and better quality of life, and this is despite the fact that these aspects are not given much attention in the design of cities, and as a result, more in cities than in villages. Mental health and social health are vulnerable. Among the effects of living in the green space is the reduction of negative effects caused by stress, which has increased a lot nowadays.

According to this theory, being in natural situations expands positive emotional responses. This can help to a certain extent to improve the stress of someone who was already under stress. Evolutionary theories in the field of preference of landscapes explain the usefulness of natural landscapes in such a way that the features of landscapes satisfy the biological needs of humans. Researchers in environmental psychology investigate the issue of whether the improvement effect of natural landscapes is the reason that people They prefer natural landscapes to urban landscapes.
Natural situations have many absorbing stimuli and activate involuntary attention, which supports the restoration and recovery of fatigue. On the other hand, urban spaces such as buildings require more direct attention to overcome the stimuli they create. . Natural spaces increase restoration and improvement. In addition to the mentioned cases, it may be possible to consider part of the positive effects of being in nature as a result of the effects that colors have on humans. Colors stimulate different emotional and cognitive effects. Red, which is more likely to attract attention, causes activation and arousal and increases excitement and liveliness, and is a sign of aggression, anger and anxiety, while green, which is less likely to attract attention, has It has a calming and relaxing effect It also seems that colors influence people's cognition and excitement. In relation to the mentioned effects, studies have shown that living in nature positively affects cardiovascular function, reduces the amount of physiological responses to stress, and improves the ability to adapt to stressful events.
 It has also been found that seeing nature reduces heart rate, removes muscle tension, lowers blood pressure and increases the electrical conductivity of the skin.

He needs nature to grow and nurture. Due to the importance of this, there is a scientific branch called nature therapy or eco-therapy that deals with the benefits of this method. In this version, the person in question should devote time to walking and walking in nature and under the gentle sunlight every day. Studies by researchers at the University of Essex in England show that nature's prescription reduces depression by 71%. This method is especially effective for treating seasonal mood disorders. In addition to nature tourism and walking, doing things like gardening also has the same positive effect. Baltimore Medical Center researchers use this method to relieve fatigue caused by treatment in breast cancer survivors. In some centers, this method is a part of the treatment and has left wonderful effects. Research shows that walking and interacting with nature is essential for the human body and mind.
