Introduction. In the conditions of large-scale Russian aggression, the question of overcoming stressful conditions, which are common to both the military and the civilian population, arises. The mechanisms of overcoming stress through special exercises recommended by professional psychologists are not always perceived by the general public as something effective and convenient for him personally, and therefore there is a need to develop an approach that is based on the cultural tradition of Ukrainians and is less prescriptive, which requires compliance with clear algorithms and rules. After all, the use of nature as a resource provides an opportunity for a creative understanding of this category and the development of a personal trajectory of psychological recovery by means of nature. Purpose. to substantiate the concept of nature as a resource of recovery in the conditions of military actions and to determine the disclosures of this phenomenon in the self-regulation of mental states. Methods. In the course of the research, the methods of analysis, synthesis, proof, comparison, abstraction, generalization, and specification were used in order to objectively study the phenomenon of nature as a resource of recovery in the conditions of military operations. Results. The concept of a resource in psychology is related to the self-creation and self-expression of an individual, which has cognitive, emotional-volitional and activity or behavioral disclosures. In the conditions of military operations, it is advisable to consider the resource as a way out of stress. According to G. Selye, stress has three phases: 1) anxiety; 2) resistance; 3) exhaustion. The signs of stress include: 1) inability to focus on a certain type of activity, when the number of errors at work increases; 2) deterioration of memory, rapid fatigue; 3) excessive excitability, rapid speech; 4) loss of food taste, appetite; 5) increasing frequency of smoking, alcohol consumption. In the conditions of military operations, we can diagnose the following signs of acute stress: shortness of breath, rapid heartbeat, increased pressure, feelings of anxiety, panic, doom, increased excitability or numbness, clumsiness, inhibition. The reaction to stress depends on the adaptive abilities and individual vulnerability of the organism. Despite the popularity of the classification of the main actions in stressful situations based on the so-called ancient brain: "fight, "freeze", "runaway", each person reacts to stress individually and it is quite difficult to predict behavior in stressful situations. It is optimal in this situation to have an arsenal of tools that help overcome stressful situations and get out of them. And using nature as a resource for recovery is a secondary aid after the primary one, which involves de-stressing through self-reality or re-reality with the help of another person nearby. Why are such methods used as shaking, removing from the scene, hugging, including the method of self-hugging; methods of included reality, such as naming objects, shifting the gaze to what is around; the method of using a pincer, a rubber bracelet that, when pulled, peels off the hand and returns to the state of "here and now, I understand what is happening and know what to do next." In acute crisis situations, the military uses a shout, a slap, a push, in order to return a person caught in a stressful situation to reality. Nature is a means of secondary help or self-help, to which the approach of S. Hobfoll’s COR theory is related, according to which a person tries to preserve the best for himself: to record memories, save them and remember his “place of strength” in moments when you it is difficult and there seems to be no way out. It can be memories of time spent with the dearest people in picturesque places, rest in the forest or near the sea. According to S. Hobfoll, a person has external and internal resources. In the case of using nature as a resource, the external can include contemplating the beauty of nature, developing the ability to rejoice in the smallest, such as: I am alive and I see the beauty of a new day, the rising sun, the morning dew, the trembling of leaves in the wind, I hear the rustling of grass, singing of birds, smelling grass, river, flowers. The use of these techniques allows you to maintain a "here and now" position, not to delve into negative thoughts and experiences, and to form a reserve bank of positive impressions. If possible, if conditions allow, it is good to use walks in picturesque places. Internal resources, in the case of using nature as a resource, include pleasant memories associated with contemplating nature or spending time in nature with friends, family, and loved ones. Also, internal resources include goal setting, which allows you to build perspectives related to time in nature or even vacation, travel for the near future (within a week), somewhat postponed (within a month) and distant (about six months to a year). Lahad, researching the symptoms of post-traumatic stress disorder, at the end of the 20th century, came to the "BASIC Ph" model, which partially incorporated E. Fromm's ideas about personality resources. The use of nature as a resource of recovery requires the unity of cognitive, emotional-volitional and activity or behavioral disclosures. Cognitive disclosure involves an understanding of the value of nature, the need to treat it with care, awareness of the psychotherapeutic effect of contemplating the beauty of nature and the life-giving force for restoring the body by staying in nature. Thanks to the cognitive disclosure, it is possible to trace the connections between the formation of an understanding of the need for a valuable attitude to nature and its real implementation. Cognitive disclosure becomes more significant when an analysis of his emotional states is added to the assessment of the characteristics of a person's knowledge. Emotions also play the role of a motivating factor. A strong emotion can activate the whole body. Emotions stabilize the mental state when they actualize a positive experience in a person's memory, which gives hope for a successful future interaction. Thus, emotions help to diagnose life situations of interaction with oneself, other people and the surrounding world. Emotional-volitional disclosure shows exactly which emotions and feelings lie at its base, and which are not characteristic of it. Human knowledge and skills find practical implementation in behavior. An activity or behavioral disclosure characterizes the practical aspect of a person's life. It reveals the degree of formation of skills of humanistic interaction with the world, attitude to nature as a value. Active disclosure allows you to compare the level of knowledge and practical skills, abilities and habits of implementing the basic provisions of life in specific behavior. Active disclosure provides space for both contemplative and nature conservation activities, which become a source of energy and a resource for recovery. Originality. The article considers the essence of the concept of " nature is an important resource for recovery in the conditions of military actions " and determines the disclosures of this phenomenon in the self-regulation of mental states. Conclusion. Therefore, in our opinion, nature is an important resource for recovery in the conditions of military operations, a means of secondary care or self-help in conditions of stress. The use of nature as a resource of recovery requires the unity of cognitive, emotional-volitional and activity or behavioral disclosures. Prospects for further research consist in the study of methods of using nature as a resource for recovery in the conditions of military operations and the development of practical recommendations for their use.
