The thermal effect of the working environment, leading to overheating of the body of workers, can manifest itself as thermal injuries, accompanied by a deterioration in well-being, a decrease in working capacity, and various health disorders. In addition, an increased air temperature can become a trigger for the activation of biological effects caused by other industrial factors— noise, vibration, harmful chemicals, physical exertion, the combined effect of which has a potentiating effect. The aim of the work was to analyze the literature data on the study of the negative impact of the heating microclimate on the health of workers and to determine measures for its prevention. The analysis of domestic and foreign sources of scientific information and publications contained in Russian and international search systems (databases eLIBRARY, PubMed, etc.) devoted to the study of the features of the formation of a heating environment and its influence on the formation of health disorders of workers in various industries and agriculture. The importance of studies of the heating microclimate as a factor of occupational health risk is shown, the directions of primary prevention of its negative impact, aimed at protecting against overheating and normalizing the thermal state of the workers’ body, are determined. Analysis of literature data allowed us to conclude that the negative health effects of the thermal effects of the working environment are currently insufficiently studied, further research is needed to assess occupational risks associated with its exposure, as well as the processes of adaptation to the thermal load of workers in various industries and agriculture, taking into account their specifics.

In modern conditions there is a high need to improve methods for establishing the nature of the combined influence of factors using modern approaches for further development of prevention measures against the negative impact of factors on the body. The purpose of the study was to investigate the combined effect of electromagnetic radiation and low temperatures with subsequent determination of the level of contribution of each factor in the formation of biological effects within the experiment by mathematical analysis of data using the method of artificial intelligence. Materials and methods. The subchronic experiment (30 days) was performed on male rats. The animals were divided into groups: combined exposure to electromagnetic radiation (70 kHz, 600 V/m) and reduced temperature (40C), isolated exposure to reduced temperature, isolated exposure to electromagnetic radiation and a control group. The establishment of biological effects was performed at stages 5, 15 and 30 days of the experiment. Changes in the body were assessed by physiological, biochemical and immunological parameters of the blood (30 indicators). Data processing was performed using computational intelligence methods (Neuro-fuzzy system). Results and discussion. The combined effect of the factors was manifested by the following biological effects: intensification of peroxidation processes with simultaneous moderate suppression of antioxidant protection, intensification of lipid metabolism was characterized by dyslipoproteinemia, manifesting in: increase in triglycerides, cholesterol and its fractions. Changes of the immune system were decrease in the ability of neutrophils to phagocytosis at different stages of the experiment, imbalance of the activation of the system of reducing the concentration of C4 at the background of increased intensity of IgM and IgG synthesis. The method of determining the intensity of the factors, developed on the basis of factor and cluster analysis, allowed to determine that during the experiment the ratios between the factors changed, but the greatest contribution was made by reduced temperature by both biochemical parameters (63%) and immunological (53%) at the same time, the level of electromagnetic radiation contribution was 37% and 47%, respectively. Thus, the reduced temperature was the leading factor in the combined effect, which added 60% to the overall biological effect throughout the study, against the effect of electromagnetic radiation for which the level of contribution was only 40%. By means of the factor analysis informative indicators, making it possible to establish the characteristics of biological effects, and therefore leading indicators in formation of biological effects were the increase in concentration of DC with simultaneous decrease in concentration of SH-groups, increase in VLDL and suppression of oxygen-dependent metabolism of neutrophil-test. Conclusion. Thus, the tested mathematical approach allowed to determine the leading role of each of the studied factors under the conditions of their combined influence in different systems, which allows to predict probable appropriate reactions of the whole organism and gives a reasonable approach to the development of preventive measures

Abstract Embedded in the centuries-old assertion that the womb was a nomadic entity wandering about the body causing hysteria and distress, persistent menstrual misinformation and misconceptions remain prevalent wherein pain disorders like endometriosis are concerned. Affecting an estimated 176 million individuals worldwide, endometriosis is a major cause of non-menstrual pain, dyspareunia, painful menses and reduced quality of life among individuals of all races and socioeconomic backgrounds. Wide-ranging symptoms may be dismissed as routine by both patients and practitioners alike due to lack of disease literacy, and lengthy diagnostic delays can exacerbate the negative impact of endometriosis on the physical, psychological, emotional and social well-being of those affected. This chapter identifies some of these challenges and explores how obstacles to best practice can be reduced in part through adoption of early educational campaigns which incorporate endometriosis as a major component of menstrual health education.

The aim of the paper was to investigate health aspects of high altitude trekking such as preparation for the physical exertion during trekking at high altitude, the impact of mountaineering on the daily life before and after the expedition, the effect of high-mountain conditions on health and well-being. It was found that in the pre-departure period trekkers commonly train to ensure that they are physically fit for the expedition. They train alone or under the supervision of a trainer. Self-prepared workouts may turn out to be insufficient due to the lack of appropriate training plans. The most challenging aspects of high altitude trekking for the body include carrying too heavy equipment, dealing with illegibly marked routes, wearing inappropriate clothing, having an unbalanced diet, not having enough water, which can lead to dehydration and infections. Misconduct by other people poses a risk. The specific type of effort involved in mountaineering requires balanced nutrition in terms of both micro- and macro-elements. To find the right combination, one has to either experiment or seek advice from a dietitian. However, relatively few people consult a nutrition coach. Among sanitary problems, the most serious one is inappropriate human waste disposal, the resulting lack of drinkable water. Some of the observed problems result from insufficient regulations regarding the conduct in the mountains and from trekkers’ lack of awareness regarding good practices in such extreme conditions.

Abstract. Introduction. When using personal protective equipment (PPE) against power-frequency electric fields (PFEF), there is a problem associated with the deterioration of the humans thermal state during a workshift when working in a hot environment. The shielding and shunting elements of the PPE increase the weight of the PPE and has an additional thermal load on a person working in a hot environment and so have a negative impact on his thermal state. The change in the indicators of the persons’ thermal state can be considered as a criteria for the impact of a complex of factors that determine the body heat exchange with the environment. Also, in addition to the impact of the PFEF and the hot environment, workers are exposed to physical exertion associated with moving around the area and lifting weights, which additionally burdens their functional state. Purpose. To study the thermal state of a person using PPE from the PFEF, when performing physical work at different thermal load levels of the environment. Materials and methods. Four practically healthy men were involved as volunteers. Before and after the experiment, the initial skin temperature indicators were recorded in 11 areas of the body surface as well as the tympanic membrane temperature and the heart rate (HR). During physical activity and rest, subjective heat and humidity sensations were also recorded every 5 minutes on the 11 areas of the body surface and the temperature of the inner surface of the clothing was determined. Before and after the experiment, the body weight of the naked volunteer and the weight of all the items included in the PPE kit were recorded. Results and discussion. During physical work at WBGT 28.0°C, ΔQts reached the permissible level (2.6 kJ/kg) after 10 minutes from the start of the work, and when working in WBGT 23.3°C – after 20 minutes, which indicated the highest rate of overheating of the human body at a higher level of the thermal load. The moisture sensitivity score at WBGT of 28.0°C by the end of the working period was 3.3. Stabilization of the HR was observed at a lower level of the thermal load, but at WBGT 28.0°C there was a HR continuous increase, which indicates a greater tension of the thermoregulation mechanisms. Conclusion. The obtained data allowed us to establish the fact of the negative impact of the use of EP-4(0) kits on the humans’ thermal state. When using the EP-4(0), it is necessary to regulate the time of continuous work in the open air: no more than 2 hours with a subsequent rest for at least 30 minutes in order to compensate heat loss as a result of using such PPE, which hinders heat and moisture exchange.

Environmental medicine generally addresses environmental factors with a negative impact on human health. However, emerging scientific research has revealed a surprisingly positive and overlooked environmental factor on health: direct physical contact with the vast supply of electrons on the surface of the Earth. Modern lifestyle separates humans from such contact. The research suggests that this disconnect may be a major contributor to physiological dysfunction and unwellness. Reconnection with the Earth's electrons has been found to promote intriguing physiological changes and subjective reports of well-being. Earthing (or grounding) refers to the discovery of benefits—including better sleep and reduced pain—from walking barefoot outside or sitting, working, or sleeping indoors connected to conductive systems that transfer the Earth's electrons from the ground into the body. This paper reviews the earthing research and the potential of earthing as a simple and easily accessed global modality of significant clinical importance.

In recent decades, the intensity of the use of pigs has increased significantly. In such conditions, the body of animals is used almost to the limit of its capabilities. In this regard, the administration of many physiological functions is disrupted, the morbidity and decrease in the performance of pigs significantly increase. The increase in the level of drug use does not solve these issues. For example, the uncontrolled use of antibiotics can lead to even more significant problems - the development of antibiotic resistance. Despite this, in modern pig breeding, considerable attention is paid to the development and implementation of methods for the prevention of diseases in pigs. An important component of such activities is to ensure optimal conditions for the comfort and well-being of animals. This, in turn, implies a reduction in the negative impact of stress factors in raising and fattening pigs. The aim of our research was to get acquainted with modern literature data on the features of the influence of stressors on productivity and physiological functions of pigs. During the writing of this review article, we reviewed data from current research on the effects of stressors on the productivity and physiological functions of pigs in rearing and fattening. For this purpose, the funds of the scientific library of Bila Tserkva National Agrarian University, scientific research systems Science-Direct and PubMed were used. An important task of veterinary service of modern pig breeding complexes is to ensure optimal parameters of the microclimate, feeding quality feed, reducing the negative impact of stress factors. Ensuring proper housing conditions contributes to the improvement of qualitative and quantitative indicators of pig productivity (at slaughter, during slaughter, etc.). In this regard, we believe that a promising area of research is to study the effects of certain stressors and their combinations on the body of pigs and find methods to correct them.

Insomnia is a widespread disorder affecting not only sleep quantity and quality, but also daytime well-being and performance, as well as having a negative impact on physical and mental health. Many people have problems falling asleep and maintaining sleep that do not reach the clinical criteria of insomnia. For all the prevalence of such sleep disorders, specialists often overlook a fundamentally important factor that affects sleep and wakefulness cycle, ease of falling asleep and daytime performance. These are circadian rhythms of the body under the control of the biological clock.This review highlights the specifics of the human biological clock and its relationship to insomnia and complaints of poor sleep. The phenomenon of the human chronotype as a set of individual preferences in sleep-wake rhythm is considered. Late chronotype, tat tends to wake up late and be active in the evening turns out to be the most vulnerable to the appearance of complaints of poor sleep and development of insomnia. This result is typical for different age groups. The reason for problems sleep for the late chronotype is the need to adjust to social demands and to fall asleep and wake up too early relative to the phase of one’s own circadian rhythm.Circadian rhythms may contribute to the formation and maintenance of insomnia. Both chronic and acute insomnia may have a chronobiological component that is not always considered. Late chronotype may be a factor further exacerbating the course of insomnia. The regularity of circadian rhythms may also be impaired in insomnia.The importance of the biological clock in the regulation of sleep and wakefulness also explains the successful approach to insomnia treatment with melatonin, which plays an important signaling role in the circadian regulation of the body.

One of the most important factors for a good result affect in sports are: lack of stress (emotional and nervous overstrain), rest, healthy sleep. The main condition is excellent food. The article considers the positive impact of the use of sports supplements to improve performance in sports and in general for the excellent well-being of the athlete. The aim of the work is to prove the use of nutritional supplements in the training of athletes, especially weightlifters, is quite effective and necessary for high athletic performance. Nutrition plays a huge role in achieving maximum results in fitness, bodybuilding and sports in general. When creating a training strategy, the basis of the nutrition program should be the use of certain types of products. Nutritional supplements, as it follows from this term, are only a supplement, a kind of support for proper nutrition and intensive training (especially with weights). Nutritional supplements are not a panacea, they can in no way replace proper nutrition and proper training. Nutritional supplements are substances that are a building material, protect and increase the function of cells in the body, and do not have a negative impact on human health. Maintaining excellent health is achieved through the use of sports supplements because the need for these drugs in athletes is very high. Athletes due to heavy physical activity spend a lot of energy, nutrients such as vitamins, minerals, amino acids. We see prospects for further research in a detailed consideration of the main components of sports supplements.

Objective. To estimate the associations between educational load and health, and elements of day’s routine among Lithuanian schoolchildren, attending classes of first stage of basic education curriculum. Material and methods. During 14–28 November, 2005, the study was performed in 108 secondary schools, providing basic secondary education in Lithuanian language. A total of 3744 schoolchildren and 1601 parents filled in an original, specially designed questionnaire. Results. More than two-thirds of the schoolchildren (69.2%) estimated their health as very good or good, and 19.2% indicated that they were not ill during the last year. Schoolchildren who reported educational load to be too high estimated their health worse (P<0.001), were ill more frequently (P<0.001), and due health disorders had to limit their regular activities. Educational load had an impact on schoolchildren’s well-being and relationships with parents. Elements of day’s routine depended on gender, grade, and place of residence. Less than one-third (32.8%) of schoolchildren reported 9–10-hour night’s sleep, 33.8% – spending 3 hours outdoors on workdays. Passive activities dominate during schoolchildren’s leisure time. More than half of schoolchildren (60.3%) spend 2–3 hours watching television, 30.7% – 2 or more hours working with computer on workdays. Conclusions. Too high educational load have a negative impact on schoolchildren’s health and well-being, relationships with parents. Schoolchildren with an adequate educational load follow recommendations of the day’s routine more frequently.
