Briefly describe the environmental risk factors.

The main environmental risk factors are physical, chemical, biological, social and psychological.
The physical impact of the external environment on the human body consists mainly in the irradiation of electromagnetic radiation of natural or artificial origin, the effects of instruments and equipment using electrical energy. The most powerful natural factor in physical impact is sunlight. Powerful radio stations, radar stations, power lines and other energy facilities are dangerous to human health.
Chemicals are widely used in industry and in everyday life (preserving, washing, cleaning and disinfecting agents, as well as means for painting and gluing various objects). All chemicals used in everyday life in small quantities are safe for health. However, violation of the rules for their use can have an adverse effect on the human body.
From the first days of a person’s life, it surrounds the world of biological creatures that are not visible to the naked eye (the world of microorganisms). All microorganisms can be divided into three groups: completely harmless to humans; conditionally pathogenic (conditionally harmful); absolutely harmful (dangerous) to health.
The introduction of unconditionally harmful microorganisms into the human body almost always causes an infectious disease. Usually this is due to a violation of the rules of general and personal hygiene, food hygiene (food preparation rules), clothing hygiene, home hygiene and the estate hygiene.
Social risk factors (uncertainty about tomorrow; the destruction of public attitudes, customs, traditions, opinions; the inability to predict the outcome of events, phenomena and situations) almost always cause tension in society that negatively affects people’s health.
Risk factors of a psychological nature (quarrels, conflicts, unwillingness and inability to communicate), as a rule, lead to tension and stress that are not conducive to maintaining and strengthening health.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
