Factors affecting human health
A person, during his life, experiences a number of factors that both positively and negatively affect his health. Factors affecting human health are estimated at more than a dozen. In addition to the genetic and biological characteristics of a person, environmental, social and physical factors also have a direct impact on him. This affects not only directly on human health, but also on the duration of his life.
The following factors, as a rule, affect the person:
- Health care
Influences on human health of this type of exposure, as a rule, have a strong influence on the further existence of a person. Pollution of our atmosphere is directly related to the deterioration of health, and, consequently, life expectancy. This has always remained, and will remain a pressing issue.
The most likely factors that accompany chemical poisoning or contamination are manufacturing plants that emit waste into the atmosphere, soil, and water. As a rule, harmful substances get into the atmosphere - gases that can have a direct effect on a person, that is, a person inhales harmful fumes together with air, like a double one, that is, through water or land. So, when released into the soil, harmful substances can be absorbed by plants, which then a person eats. The same goes for water. A person uses water for personal purposes, without even knowing what harmful substances are contained in it, and what they threaten. Since most of the gases emitted into the atmosphere can easily be combined with water, the regions with active industry have not only a polluted atmosphere, but also polluted water and soil.
Thus, the factors shaping human health, in this case, cannot exceed pollution factors, and therefore in industrial areas, children are more likely to get sick and residents are more likely to suffer from oncological diseases, which significantly reduces their life.
It should be noted that the impact of polluted atmospheric air on the population is due to such objective principles:
Variety of pollution - it is believed that a person who lives in an industrial area can be affected by about several hundred thousand chemical and toxic substances. In a certain area, a limited amount of harmful substances may be present, but in a higher concentration, moreover, that a combination of certain substances may cause an increase in their negative impact on a person.
Massive exposure - a person inhales approximately 20,000 liters of air per day, and even minor concentrations of a toxic substance that are contained in the air, comparable to such inhaled volumes, can cause a significant intake of toxins into the body.
Access toxins in the internal environment of the body. As you know, the lungs have a surface of about 100 square meters, which allows them to absorb harmful substances and disperse them over the large surface of the organ. Toxins have direct contact with blood, because from the lungs, they immediately fall into the systemic circulation, passing the toxicological barrier, the liver, on its way.
The difficulty of protection.Refusing to eat contaminated food or water, a person still continues to absorb toxins through the atmosphere and air.
Atmospheric pollution, as a rule, negatively affects the body's resistance, the consequence of which is increased morbidity and a number of physiological changes in the body. Factors affecting human health in this case, reduce the average life expectancy.
If we compare atmospheric pollution, it is ten times more dangerous than pollution of water or soil, because through light toxins directly enter the blood.
The main pollutants of the soil are chemical waste leaks, improperly buried or improperly stored, the deposition of harmful substances from the atmosphere on the soil, as well as the abundant use of chemicals in agriculture.
In Russia, the soil is contaminated with pesticides by almost 8%. At the moment, it is most likely that almost all water bodies are amenable to anthropogenic pollution.
The factors influencing human health in chemical terms are so diverse that it is impossible to cope with them all.Since the scale of production every day grows in a geometric sequence, and to restore the resources of nature requires dozens or even hundreds of years.
The main physical factors that adversely affect a person are noise, electromagnetic radiation, vibrations, and electric current.
Let us examine each of the types of negative influence separately.
Noise - a complex of sounds and sounds that can cause disturbances or discomfort in the body, and in some cases even the destruction of the hearing organs. So noise at 35 dB can cause insomnia, noise at 60 dB can irritate the nervous system, noise at 90 dB causes hearing loss, depression of the state, or, conversely, leads to excitation of the nervous system. Noise greater than 110 dB can lead to noise intoxication, which is expressed, like alcohol intoxication, as well as to excitement and neurasthenia. The main sources of noise are transport, both automobile, and railway, and aviation, and also enterprises.
Vibration is oscillatory processes that can have a wide range of frequencies resulting from the action of a mechanism transmitted vibrational energy. It can be both transport and enterprises.
Electromagnetic radiation, as a rule, is transmitted by radio or television stations, radar installations, various industrial devices. Constant exposure to electromagnetic fields or radio waves can lead to changes in the nervous or endocrine system.
As a rule, it is caused by the previous influence on previous generations of the population of toxic or polluting substances, which can eventually result in hereditary diseases of the descendants, and as a result - low life expectancy of certain parts of the population. Also, the next generation may be predisposed to certain diseases.
In many ways, it all depends on the development of the health infrastructure in a particular country. Since this directly depends on the state of health of the population and the duration of its life. The factors that determine human health are significant in this case. It takes into account general public awareness, funding of medical structures, the development of innovative technologies and methods of treatment, as well as timely diagnosis, which can be successful only with the availability of expensive equipment for manipulation.
Try to eat right, maintain a healthy lifestyle and not be nervous. From this, your life expectancy will increase by many years. Be healthy!
