Environmental Health: How Our Surroundings Shape Our Well-being
Angel Okoli 
Environmental health looks at how our environment affects our general health and well-being. It is about realizing how our living, working, and recreational environments impact our health. we redefined what health is here
Have you ever woken up feeling exhausted because of poor sleep in a hot, noisy, bug-infested room? Or worked in a space next to a factory or construction site, filled with harsh chemical smells and constant noise?
The word "awful" hardly begins to capture how unpleasant it is.
We briefly covered sleep and some effects of insufficient or poor-quality rest on your health in our previous article. These kinds of surroundings don't just disrupt sleep; they also interfere with your peace of mind and place constant strain on your body. Over time, this can affect both your physical and mental health, creating an environment that makes it difficult to rest, focus, or work effectively.
What is environmental health?
According to the World Health Organization (WHO), environmental health addresses all physical, chemical, and biological factors external to a person, and related behavioral factors, encompassing the assessment and control of these elements to prevent disease and create supportive environments, excluding purely social/cultural behaviors or genetics.
So, as we have said above, environmental health is all about how the world (external factors) around us affects our health. When our surroundings support us, our bodies and minds function better. When they don't, our health often feels the strain.
What Counts As Our “Environment”?
When we think of the environment, it’s easy to imagine forests, oceans, or outdoor spaces. But our environment is much closer and more personal than that. It includes the spaces we wake up in, work in, learn in, and relax in every day.
Our environment covers things like the air we breathe indoors and outdoors, the water we use, the level of noise around us, the cleanliness of our surroundings, and how safe or comfortable a place feels. It also includes natural elements like sunlight, fresh air, and green spaces, as well as built environments such as homes, schools, roads, and workplaces.
In simple terms, anything in your surroundings that can affect how you feel, function, or stay healthy is part of your environment.
How The Environment Affects Our Health
Our topic is “how surroundings shape our well-being”. Here are some examples of how:
• Air pollution: Living in places with high levels of dust, smoke, or pollution can cause headaches, exhaustion and respiratory problems.
• Noise pollution: Constantly loud noises from factories, construction sites, or traffic can cause stress, interfere with sleep, and make it difficult to focus.
• Housing conditions: Frequent illness, allergies, or a persistent sense of discomfort can be caused by damp, poorly ventilated, or dirty spaces.
• Access to nature: Areas with trees, sunlight, or fresh air can improve mood, lower stress levels, and increase concentration.
• Community safety: People who live in unsafe neighborhoods may experience anxiety or have limited mobility, which may have a negative effect on their mental and physical health.
Did You Know?
Even if you don’t smoke, being around secondhand smoke can harm your lungs, increase the risk of heart disease, and quietly affect your health.
Every aspect of “our environment” counts. While we can not control everything in our environment, simple changes like opening a window, tidying your home, or even adding a plant can make a noticeable difference.
Seven Concepts Of Environmental Health
To fully grasp how our environment affects us, it helps to break it down into seven key concepts. Each one explains a part of the connection between the environment and our health.
1. Toxicity
The term "toxicity" describes a substance's potential harm to the body. Certain chemicals, pollutants, or natural substances can cause illnesses, harm organs, or even have an impact on long-term health.
For instance, inhaling smoke, much exposure to chemicals used in household cleaning, or drinking contaminated water can irritate the lungs, trigger skin reactions, or eventually result in more serious health problems.
2. Exposure
How, when, and how frequently we come into contact with potentially dangerous substances is known as exposure. If exposure occurs frequently or for an extended period of time, even safe environments can become dangerous.
For instance, living close to a busy road exposes you to car emissions every day, which can eventually harm your breathing and general health. We can take basic safety measures, such as using air purifiers, when we are aware of exposure.
3. Dose/Response
The concept of dose-response demonstrates that exposure level is important. A hazardous material may not have much of an impact in small doses, but large or frequent exposures can be harmful.
For instance, inhaling smoke for a short while may be acceptable, but prolonged or frequent exposure can cause major harm to internal organs.
4. Individual Susceptibility
Different people respond differently to environmental risks. A person's susceptibility is influenced by a number of factors like age, genetics, current health conditions, and lifestyle.
For instance, compared to a healthy adult, children, the elderly, and those with chronic illnesses are frequently more vulnerable to chemical exposures, intense heat, and air pollution. When choosing a neighborhood or setting for your home, it's critical to consider factors such as these. Just because you can survive there doesn't mean it's healthy for everyone else.
5. Risk and Benefits
Every environmental factor carries potential risks but sometimes there are benefits too. Understanding both helps us make better decisions for our health.
For instance, excessive exposure to sunlight raises the risk of cancer or skin damage even though it provides vital vitamin D. We can maximize benefits and minimize risks by striking a balance between the two.
6. Environmental Justice
This ensures that regardless of social status, location, or income, everyone has equal access to safe and clean environments.
For instance, Some neighborhoods may experience higher pollution or lack green spaces, which can impact the health of residents over time. Environmental justice reminds us that healthy surroundings are a basic right, not a privilege.
7. Community Resources
People are better equipped to safeguard their health and promote healthier environments when they have access to trustworthy information, support networks, and neighborhood resources.
For instance, local health departments, environmental organizations, and government websites provide guidance on safe air quality, clean water, or reducing chemical exposure. Knowing where to turn makes it easier to take action and improve both personal and community well-being.
We can gain a better understanding of how our environment affects our health by understanding these seven ideas. From recognizing harmful substances to taking advantage of community resources, small, informed steps in daily life can create a healthier environment for ourselves and those around us.
Creating Healthier Surroundings
Here are a few tips on how to take better care of your environment.
• Keep your space clean and clutter-free.
• Focus on the 3 Rs (Reduce, Reuse, Recycle).
• Open windows for fresh air.
• Let in natural light every once in a while.
• Add plants or greenery to your environment.
• Keep hazardous chemicals in a safe location.
• Be mindful of indoor air quality (avoid smoking indoors and consider using air purifiers if needed.)
• Conserve energy and water at home.
• Always make sure to dispose your waste properly.
• Use non-toxic and eco-friendly products.
• Add personal touches that make you feel calm.
• Spend time outdoors whenever possible.
• Cut down on single-use plastics by using reusable bags and bottle.
• Support green initiatives.
Summary
Environmental health is a shared responsibility. It's one aspect of health that affects the entire community just as it affects one person. As we make our homes a sanctuary and breathing space, we should also allow that special care touch our public environment. That way we'll create a safer and healthier environment for everyone.
