The notion of Health usually linked to the absence of a disease , although specialists emphasize that the concept is associated with complete physical and psychic well-being of a person. Environmental , meanwhile, is that linked to ambient (the context or the environment).

The idea of Enviromental health , thus, mentions the health dimensions that are found determined by different environmental factors , whether biological, chemical, social or otherwise.

To understand what environmental health refers to, we must understand that the environment (the environment, the scope of work, etc.) can affect the health of the current population and even the Next generations . Therefore, carrying out activities that improve their conditions has a positive impact on people's health.

In other words: the evaluation, control and correction of environmental factors that affect health effectively results in better health for people . Environmental health, therefore, acts on these issues.

In general, environmental health is associated with the fight against contamination . A factory that produces fumes of toxic smoke and pollutes water with its discharges is a problem for environmental health: it can cause from poisoning to cancer in people who live near it. That is why it is necessary to control its operation.

The precarious housing and the poor feeding They are also factors that analyze environmental health. Two people with the same genes will have different state health if one lives in a neighborhood without drinking water and feeds on junk food and the other resides in an urban environment with all the comforts and has a varied diet.

The factors that influence environmental health are many and are grouped into several categories. Listed below are some of them.

Physical factors

* Atmospheric : are those related to air and changes in weather , which affect both our mood and our physical health. A clear example are the pains and diseases that appear with sudden changes in temperature, such as certain respiratory problems and allergies;

* Sidérico : it is about the general characteristics of our planet, the Moon and the Sun, as well as the other surrounding bodies and comets, since all this affects the environment and, consequently, our lifetime and our environmental health;

* Electricity : The use of appliances or industrial machinery can cause electric shocks of various magnitudes, with consequences ranging from disability to death. Paradoxically, lack of access to electricity can also lead to accidents , since the use of fuel to light a home can cause poisoning or burns, for example.

Chemical factors

They are the ones that most commonly act on environmental health, since they are found in the air, in the water and in all products that we consume daily ; In fact, they can enter our body through the nostrils, digestive tract or through direct contact with our skin or the different mucous areas of the body. It is worth mentioning that his action It can occur individually or in combination.

Some of the chemical factors are inorganic natural elements; in this group are mercury and lead, among other metals and nonmetals that can be inhaled, absorbed or ingested , in solid or liquid state, as appropriate. There are also natural organic substances, and both types in their synthetic versions (a very common synthetic organic substance is the pesticide used in agriculture).

Biological factors

In this category we find: bacteria , parasites (this includes unicellular and multicellular, in addition to their toxins), viruses, various microorganisms (such as mycoplasmas), fungi and mycotoxins, allergens of biological origin, vegetables (for their toxins or those derived from pesticides, by example), vaccines (especially those that include aluminum and mercury).
