The work was performed by pupils of 10 "B" class Nadeeva Milya and Kaldina Anna

Human ecology is the science of human relationship with the environment in various aspects (economic, technical, physical and technical, socio-psychological) and is designed to determine the optimal conditions for human existence, including the permissible limits of its impact on the environment. The relationship with the human environment, as an organism, is studied by autecology, the ecology of human communities - synecology. F. Bacon

Chemical pollution of the atmosphere Industry household boiler houses transport Main source of pyrogenic pollution: thermal power plants, metallurgical and chemical enterprises, boiler plants (consuming more than 70% of the annually produced solid and liquid fuels.) Main harmful impurities of pyrogenic origin: carbon monoxide sulfur dioxide and sulfuric anhydride nitrogen oxides hydrogen sulfide and carbon disulfide fluorine compounds chlorine compounds

Human exposure to sulfur and sulfuric anhydride Poisoning symptoms: runny nose, cough, hoarseness, sore throat. Inhalation of high concentrations - choking, speech disorder, difficulty swallowing, vomiting, acute pulmonary edema is possible. Human exposure to nitrogen oxides gas mixed with oxygen is used for anesthesia. number of symptoms Small amounts of dullness of pain sensitivity. Small amounts feeling drunk. Inhalation of pure gas causes narcotic state and suffocation

weather and human well-being Biorhythm - a set of rhythmic processes in the body (rhythms of the heart, respiration, bioelectric activity of the brain). Circadian rhythms and biorhythms The study of changes in circadian rhythms reveals the occurrence of some diseases at the earliest stages Climate and health XVII century - the foundations of a scientific direction in medicine about the influence of climatic factors on human health were born 1725 - the beginning of studying the influence of climate, seasons and weather on humans in Russia

nutrition and human health Doctors say that good balanced nutrition is an important condition for maintaining the health and high performance of adults, and for children it is also a necessary condition for growth and development. For normal growth, development and maintenance of vital functions, the body needs proteins, fats, carbohydrates, vitamins and mineral salts in the amount it needs. Regular overeating, consumption of excessive amounts of carbohydrates and fats - the cause of the development of metabolic diseases such as obesity and diabetes. Many food products have bactericidal effects, inhibiting the growth and development of various microorganisms.

The surrounding landscape can have various effects on the psychoemotional state. landscape as a factor of health Nature increases vitality, calms the nerves. Forest, especially forest air, has one of the strongest health effects. Outdoor recreation is useful for city dwellers due to the intense rhythm of life and polluted air, including noise pollution and the overall urban environment.

The birth of a large number of premature babies, which means they are physically immature. It is associated with a violation in the genetic apparatus. 6. "Return" of infectious agents that are able to live in the human environment and become causative agents of influenza, viral cancer and other diseases. Today, for example, the incidence of tuberculosis has increased even in developed countries due to antibiotic resistance, impoverishment and high urban density. 7. Abiological tendencies, which mean such lifestyle features as physical inactivity, smoking, drug addiction, etc. They are the cause of obesity, cancer, cardiac diseases, etc. At present, all these tendencies are characteristic to varying degrees for all human habitats, but they appear most prominently in the urban environment.

One of the significant negative risk factors affecting the health of the population is alcoholism, tobacco smoking and drug addiction. A bad habit is a pre-illness if it is not stopped in time. Tobacco smoking has become an epidemic. Over the past 5-10 years, the number of drug users in the country has increased 4 times, the number of deaths from drug use has increased 12 times, including 42 times among children. Alcohol addiction remains the most widespread in Russia. Every 20 seconds a person dies from drugs and related diseases in our country, more often a young person. The share of Russia in the world drug trafficking has increased to 8%.

The share of Russia in the world drug trafficking has increased to 8%. Any addiction is the self-enslavement of a person by his desires. If some needs (for food, water, sunlight, safety, etc.) are important or even obligatory for survival, then others are maladaptive in nature, subjugating the will of a person, leading to harmful consequences. The problem of the formation of a healthy lifestyle is the problem of the formation of a worldview and the corresponding principles of behavior. Further improvement of the health status of the population requires an approach to health from the point of view of its broad understanding and taking into account all factors that determine health: lifestyle, social well-being, psychological climate, physicochemical factors of the environment. Drug addiction is understood as a painful attraction to substances of plant or synthetic origin that affect the central nervous system and cause feelings of euphoria, intoxication, stunning, pain relief, hallucinations. The word drug addiction is derived from the Greek words narke (numbness, sleep) and mania (madness, passion, attraction). The term "drug addiction" was used at first in relation to drug abuse in a narrow sense (opium and its drugs, hashish, marijuana, marijuana), and later was extended to a wide range of substances that stimulate the central nervous system, sedative drugs and others.

Place of the course “Human Ecology. Culture of Health "in the group of disciplines of the natural science cycle. "The only beauty I know is health." G. Heine Presentation by OV Polovnikova, Teacher of Ecology MBOU-Secondary School No. 1 R.p. Stepnoe Sovetsky District Saratov Region

In the modern world, the following factors play the greatest role in the occurrence of diseases: Physical inactivity Overeating Information abundance Psychoemotional stress

Diseases of civilization Cardiovascular Oncological Allergic Mental

Human ecology (anthropoecology) This is a complex science that studies the laws of human interaction with the surrounding cosmoplanetary environment. R. Park, E. Burgess - 1921

The purpose of human ecology To determine the nature and direction of the processes arising from the impact of the environment on human communities, and to assess their consequences on the life of people.

Health (WHO) is the absence of disease, a state of physical and social well-being.

Social factors affecting health: GNP allocation to health care Availability of primary health care Immunization rate of the population Nutritional status of children Infant mortality rate Average life expectancy Hygienic literacy of the population

Factors affecting health

Factors negatively affecting health ……… ……… ……… ……… ……… ……… …… ..
