Environmental Factors that Affect Health

What are Environmental Factors?

According to the WHO, environmental degradation causes 23% to 25% of global illness cases and deaths, respectively, posing a substantial danger to public health globally.

Environmental variables may have a significant impact on your health, ranging from the quality of the air you breathe to the state of the roads you travel on. Furthermore, due to both environmental and human-caused activities, these elements have altered significantly throughout time.

Here, in this study, we’ll look at different but significant environmental elements that impact health. But, before that, we’ll discuss the environment and the importance of environmental health.

Importance of Environmental Health

The word “environment” can be defined as the total of all components, variables, and situations in the environment that can affect the development, activity, or survival of an organism or group of organisms.

It is critical to maintaining a healthy environment in order to help individuals live longer and have a better standard of living. Communities can limit their exposure to illnesses and chemicals that have a damaging effect on the body by improving their ecological environment. Environmental health measures can enhance people’s lives in a variety of ways, but they may have the greatest impact on individuals who are already in poor health.

Environment and Personal Health

Extensive research on the interplay of human health and environmental dangers has shown that direct or indirect exposure to hazardous agents and modification of life-sustaining ecosystems have a substantial influence on public health. Large-scale economic expansion and exponential population growth, agricultural intensification, industrialization, and excessive energy use have all contributed to environmental destruction and public health issues.

Significant environmental health risks are linked to a severe lack of public infrastructure, pervasive poverty, issues with drinking water and sanitation, a lack of healthcare facilities, and rising industrial waste concerns. Climate change, according to environmental health specialists, may modify disease patterns, rendering populations more vulnerable to various ailments. Global warming has also been linked to an increase in floods, wildfires, and superstorms, all of which can have serious consequences for human health.

5 Environmental Factors Effecting Your Health

A variety of environmental concerns can obstruct people’s health and well-being. Chemical pollution, air pollution, climate change, disease-causing organisms, a lack of access to health care, inadequate infrastructure, and poor water quality are all examples of these problems.

1. Air Pollution

Air pollution’s impact on people has been proved to be a major public health problem, not only because of its part in climatic changes but also because it can enhance illness and death.

When ecologists talk about polluted air, they’re referring to any solid particles and liquid droplets, as well as gases, floating in the air and causing injury or poisoning. Automobile emissions, as well as damaging by-products of industrial activities, are some of the most severe and common types of air pollution. Several organic air pollutants, on the other hand, might be harmful to one’s health; pollen and mold spores, for example, are frequently connected to respiratory problems.

2. Poor Quality of Water

More than 780 million people lack access to safe drinking water, and about a third of the world’s population does not have access to adequate sanitation (e.g., clean bathrooms). The health consequences are staggering: each day, more than 2,200 children die as a result of illnesses caused by contaminated water. Industrial waste and pollution, a lack of access to efficient water treatment and sanitation services, and antiquated plumbing infrastructure are all issues that can contribute to poor water quality.

3. Toxic Chemicals

Chemicals can have a variety of effects on human health, and frequent exposure to hazardous or alien compounds can lead to health problems. The discipline of chemical safety is concerned with reducing the harmful effects of both natural and manmade substances. Chemical safety, in particular, aims to protect human and environmental health against possible poisons; it focuses on naturally occurring chemicals as well as manufactured chemicals utilized in industrial processes or produced as by-products of manufacturing activities.

Toxicology is the study of compounds that have a hazardous impact on the human body, whether eaten or absorbed through natural surroundings. Public health authorities who specialize in chemical safety frequently focus on toxicology. Chemical risk assessment, which includes scientists and doctors determining the complete biological consequences of a drug, is another crucial part of public health.

4. Climatic Changes

Climate change, as well as the increase in natural catastrophes that have followed the shift in Earth’s climate, is another environmental concern with major implications for human health. Climate change, according to the National Environmental Health Association, is the single greatest human health danger of the twenty-first century.

Increases in the planet’s temperature, as well as more frequent heavy rains and runoff, are all examples of how climate change disturbs the natural environment, which can hamper health and increase disease vulnerability.

As a result of the varied effects, people may be more susceptible to neurological and respiratory disorders, diarrhea, and other problems. Natural catastrophes are becoming more common due to global warming, wreaking havoc on cities and neighborhoods and occasionally resulting in fatalities. Droughts, wildfires, storms, and cyclones are just a few examples.

Global Environmental Issues

According to WHO estimates, global climate challenges cause more than 12.6 million fatalities per year. These include soil contamination, UV radiation, and biodiversity loss, in addition to the challenges discussed below. More than a hundred illnesses and injuries have been connected to environmental health risks, according to the statistics. These challenges often have the biggest impact on disadvantaged populations who are already vulnerable to health care.
