From the quality of the air you breathe to the condition of the roads you drive on, environmental factors can have a major influence on your health. What’s more, these factors have evolved considerably over time, due to both natural and human-caused events. Professionals in the environmental health field examine how people interact with the world around them, chronicling the many ways that these interactions can impact physical fitness, vulnerability to disease, and other aspects of human wellness. In this article, we will explore eight key environmental factors that affect health:
Why Is Environmental Health Important?Through strategic efforts to improve environmental health, public health professionals can enhance personal wellness for individuals, families, and communities. The Benefits of Optimizing Environmental HealthMaintaining a healthy environment is essential for helping people live longer and for enhancing their quality of life. Consider a sobering statistic from Healthy People, which notes that 23% of all deaths (and 26% of deaths among children ages 5 and younger) result from entirely preventable environmental health problems. By optimizing environmental health, communities can reduce exposure to disease, as well as to pollutants that have a toxic effect on the body. The benefits of environmental health interventions can improve life for everyone, but may have the most pronounced effect among those who are already in vulnerable health. As Healthy People points out, “Poor environmental quality has its greatest impact on people whose health status is already at risk.” How Environmental Factors Can Impact Personal HealthEnvironmental health advocacy is a top priority in the public health field, as environmental factors continue to adversely affect individual and population health. For example, consider the looming threat of climate change. Environmental health researchers say that climate change may result in changed disease patterns, making communities susceptible to different illnesses. Additionally, climate change has been linked to an uptick in floods, wildfires, and superstorms, all of which can play profound roles in harming human health. Poor industrial hygiene is another example of how environmental factors can impact wellness. As Verywell Health notes, “Many of the materials needed to advance industries and technology, like heavy metals or even some plastics, can also hurt the human body and even lead to serious medical conditions.” In other words, industries that are irresponsible with manufacturing and waste disposal may be poisoning the natural world, impacting our physical well-being. Environmental Health as a Community Health ConcernEnvironmental health isn’t just a matter of individual wellness; it’s also a matter of community well-being. Simply put, the conditions in and around our homes, schools, playgrounds, and workplaces can have a major impact on our families and neighbors. For example, factors such as pollution and litter can make residents less inclined to go outside for exercise and recreation, potentially making the entire community more prone to disease. Aspects of the built environment, such as infrastructure, can also impact community health. For instance, areas with poorly maintained roads have higher risks of car accidents that result in injuries, and inadequate sanitation infrastructure can increase the prevalence of disease in local populations.

It’s not only important to strive for optimal environmental health. It’s also beneficial, both for individuals and their surrounding communities. Some of the benefits include: cleaner air quality, cleaner water, reduced hazardous waste, increased access to healthy foods, safer outdoor environments for adults and children, improved population health, and improved health equity. The 8 Environmental Factors That Can Impact Your HealthA number of specific environmental issues can impede human health and wellness. These issues include chemical pollution, air pollution, climate change, disease-causing microbes, lack of access to health care, poor infrastructure, and poor water quality. 1. Chemical SafetyDifferent chemicals can impact human health in different ways, and often, exposure to dangerous or foreign substances creates health vulnerabilities. The chemical safety field is concerned with minimizing the effects of both natural and synthetic chemicals. More specifically, chemical safety seeks to safeguard human and environmental health from exposure to potential toxins; it focuses on chemicals that exist in the ambient world, as well as synthetic chemicals that are used in industrial processes or are the by-products of manufacturing activity. Public health officials who work in chemical safety often focus on toxicology, which is the study of substances that have a toxic effect on the human body, whether when ingested or when absorbed through natural surroundings. Another important aspect of public health is chemical risk assessment, which involves scientists and clinicians working to determine a substance’s full biological effects. This is a critical field of public health: According to the World Health Organization (WHO), more than 1.6 million deaths in 2016 were due to exposure to selected chemicals. Some examples of dangerous chemicals in the environment are heavy metals and toxins that find their way into the water supply and harmful pesticides that make their way into the food supply chain.

2. Air PollutionStudies have shown that air pollution effects on humans are a significant public health concern, not only because of their role in climate change, but also because exposure to air pollution can increase morbidity and mortality. When environmental scientists talk about air pollution, they’re describing any solid or liquid particles, as well as gases, that are suspended in the air and have harmful or poisonous effects. When we think about air pollution, we tend to think in terms of human-caused pollutants, and rightly so: Some of the most dangerous and ubiquitous examples of air pollution include car and truck exhaust, as well as polluting by-products of industrial processes. However, many natural air pollutants can cause health concerns; for example, pollen and mold spores are often linked with asthma and allergies. According to the WHO, air pollution effects on humans are significant. For example, air pollution causes:

3. Climate Change and Natural DisastersAnother environmental issue with serious ramifications for human health is climate change, along with the increase in natural disasters that has accompanied the shift in Earth’s climate. The National Environmental Health Association lists climate change as the single biggest human health threat of the 21st century. Climate change disrupts the natural world in a number of ways that can impede health and increase vulnerability to disease; these include increases in the planet’s temperature and more frequent heavy rains and runoff. The various impacts may result in greater vulnerability to nervous and respiratory diseases, diarrhea, and more. Additionally, climate change increases the frequency of natural disasters, often having a ravenous effect on homes and communities and sometimes resulting in loss of life. Wildfires, hurricanes, cyclones, and droughts are just a few examples.

4. Diseases Caused by MicrobesDiseases caused by microbes — also known as microorganisms — present another area of public health concern. Trillions of microbes exist within the human body, and they also live in water, soil, and air. Most of them have no negative health effects, and many microbes perform important biological functions, such as supporting digestive and immune health, according to the National Human Genome Research Institute. Bacteria, viruses, and fungi are types of microbes. Harmful microbes, which are more commonly called pathogens or germs, can infect humans and cause illness. Eating is one of the primary ways in which humans can contract diseases caused by microbes. One example is food poisoning from E. coli, a type of bacteria that can be found in the environment and in foods, and which can cause respiratory illness, urinary tract infections, and other adverse health effects. There are also a number of harmful microbes that live in the soil. Humans can come into contact with them by ingesting them (through contaminated food) or through inhaling them (through soil particles in the air). Tetanus and botulism are examples of diseases caused by soil-borne microbes. More Resources About Diseases Caused by Microbes
5. Lack of Access to Health CareAnother environmental factor that contributes to disease and overall poor health outcomes is living in an area with a lack of access to health care services. According to Healthy People, “Many people face barriers that prevent or limit access to needed health care services, which may increase the risk of poor health outcomes and health disparities.” Some factors that contribute to lack of access to health care are economic instability, unreliable transportation to clinical facilities, and simple lack of education about the importance of preventive care. Individuals who don’t have access to health care services (including pharmaceuticals as well as dental care) are at a higher risk for chronic conditions, which may include asthma, cancer, diabetes, or heart disease.

6. Infrastructure IssuesInfrastructure issues can also have a major impact on community health. Examples include the following:
Overcoming poor infrastructure requires the right allocation of resources from local, state, and federal governments, as well as a qualified workforce to keep infrastructure properly maintained. More Resources About Infrastructure Issues To learn more, consider these resources:
7. Poor Water QualityVerywell Health reports that across the world, more than 780 million people don’t have access to clean drinking water; shockingly, about a third of the world’s population lacks access to proper sanitation services (e.g., clean bathrooms). The health implications are sobering: Each day, more than 2,200 children die due to diseases caused by poor water quality. A number of factors can contribute to poor water quality, including industrial waste and pollution, lack of access to proper water treatment and sanitation services, and outdated plumbing infrastructure.

8. Global Environmental IssuesGlobal environmental issues account for more than 12.6 million deaths each year, according to WHO data. Along with the issues mentioned here, these can include soil pollution, ultraviolet radiation, and biodiversity loss. According to the data, more than 100 illnesses and injuries can be directly linked to environmental health concerns. Often, these issues have the greatest impact on communities that are poor and already have significant health care vulnerabilities.
