The Role Of Environment On Health

The environmental factors affect everyday living and play a key role in bringing health differences across the geographic areas. Health is a state of complete physical, mental and social wellbeing and is not merely the absence of disease or illness. Environmental health can be defined as the interconnections between people and their environment by which human health and a balanced non polluted environment are sustained or degraded. The interaction between human and ecological factors significantly impacts human health by either directly or indirectly. The environmental factors can be defined as the identifiable element within the environment that affects an organism’s survival operations and growth.

The natural environments have a benefit in our health and also in good quality life. We need a good and supportive environment for a good health.  The environment in which we live is a major determinant of our health and wellbeing. We depend on the environment for energy and the materials needed to our sustain life such as:

health problem is likely linked to physical, biological and even economic factor.

Importance of environment on health

• Safe drinking water
• Nutritious food
• Safe places to live.
•  Many aspects of our environment in which both built and natural environment can impact on our health. We live in cities, towns, or rural areas the environment around us significantly influences our well-being. It's vital to consider how the place we live affects our health and to address broader environmental issues that impact everyone.

Five Environmental Factors:

  The air we breathe, the water we drink, the food we eat and the homes, buildings and neighborhoods we live and work in can all contribute to environmental health problems.

The primary five environmental factors impacting our health are:

·         Pollution

·         Deforestation

·         Solid Waste Pollution

·         Chemical Exposure

·         Change in Climatic Conditions

Pollution:

  Pollution is the introduction of harmful materials into our environment. These pollutants can come from natural sources, like wildfires, or from human activities, such as vehicle emissions and industrial waste. The main types of pollution include:

• Air Pollution:  Leads to respiratory problems, heart disease and premature death.

• Water Pollution: Contaminated water can cause gastrointestinal diseases and developmental issues.

• Noise Pollution:  Constant exposure to loud noises can increase stress and lead to hearing loss.

• Soil Pollution: Contaminated soil can impact food quality and lead to long-term health issues.

• Radioactive Pollution:  Exposure to radiation increases cancer risk.

• Deforestation:

·           Deforestation refers to the cutting down of trees and the destruction of forests. The loss of forests for human development or natural causes can significantly impact health.  These can either be for human habitation and use or natural causes. Green spaces and natural environments improve mental health, reduce stress and encourage physical activity. Lack of access to these areas can contribute to higher rates of chronic diseases and mental health issues. A reduction in biodiversity can affect ecosystem services such as clean water, air and fertile soil, which are essential for human health and well-being.

Solid Waste Pollution:

 Solid waste pollution is also referred to as a type of pollution, along with air water noise and soil pollution. Garbage and industrial waste can accumulate leading to toxic environments that negatively affect air quality and increase the risk of diseases.

·         Air Quality

  Exposure to pollutants like particulate matter, nitrogen dioxide and ozone can lead to respiratory diseases like asthma, bronchitis, cardiovascular problems, and even premature death. Pollution from vehicles, industrial emissions, and wildfires are major contributors. Poor indoor air quality also due to sources like tobacco smoke, radon, volatile organic compounds (VOCs) from household products, and cooking with solid fuels, can cause respiratory issues, lung cancer, and exacerbate allergies and asthma.

Water Quality:

Drinking Water Contamination: Contaminants such as bacteria heavy metals, pesticides, and industrial chemicals in water supplies can cause gastrointestinal diseases, neurological problems, and developmental issues in children. And Lack of access to clean water, poor sanitation, and inadequate hygiene practices contribute to the spread of diseases like cholera, typhoid, and diarrhea, especially in developing countries.

 

Chemical Exposure:

                  Chronic exposures to the chemicals are commonly used in agriculture that can lead to health problems such as cancer, endocrine disruption, and neurological damage. Substances like asbestos, benzene, and solvents are associated with cancers, respiratory diseases, and reproductive health issues. Exposure to metals like lead, mercury, and cadmium, often through water, air, or food, can cause neurological damage, kidney dysfunction, and developmental delays in children.

    

Change in Climatic Conditions: 

                   Climate change is not just an environmental issue it has also effect on a health. Climate c change is increasingly recognized as a global health threat. There are several causes of climate change. The most significant effect on the climate is the increasing trend in the concentration of greenhouse gases and global warming in the atmosphere. Rising temperatures, extreme weather events, and shifting ecosystems contribute to a range of health problems. These include:

Heat-related illnesses during extreme temperatures

• Malnutrition: from disrupted food supplies

• Infectious diseases: like malaria and dengue, which thrive in warmer climates
• 
  
  
  

Environmental Threats to Health:

                Our environment can expose us to harmful physical factors, contributing to various health risks. Some key sources of environmental health threats include:

• Air pollution: From car exhaust to wildfire and e-cigarette smoke to ozone pollution is a mix of natural and manmade substances found both indoors and outdoors.

• Flame retardants: There are hundreds of chemicals used in consumer products from electronics to furniture that help prevent the spread of fires.

• Lead: Old paint contaminated soil and water pottery and even house dust are a few ways people are exposed to this metal.

• Per fluorinated chemicals: These compounds help reduce friction and also are used to make products resistant to stains water and grease.

• Smoke: A single cigarette is chock full of hundreds of chemicals including arsenic formaldehyde and lead.

• Pesticides: These chemicals kill repel or control pests from weeds and fungus to insects.
• 
  
  
  

Practical Steps to Reduce Environmental Issues

   Environmental problems often stem from human activities, but there are several practical measures we can take to reduce these issues: in order to stop deforestation

• Cut back on driving and encourage greener modes of transportation

• Plant more trees :to combat deforestation

• Reduce the use of cars: and promote cleaner transportation

• Use renewable energy sources: to lower greenhouse gas emissions

• Reuse and recycle: to manage waste more effectively

• Dispose of hazardous waste :safely to prevent contamination

Conclusion:

                      The environment is an integral part of the determinants of health. It can significantly influence human health both positively and negatively. Improving environmental conditions through better policies personal habits and community efforts can promote public health, reduce disparities and create a healthier future for everyone. We can significantly improve global health outcomes and create a more equitable world by addressing environmental risks and promoting healthier surroundings.
