Environment and Health: How Clean Air, Water, and Nature Shape Our Health
Introduction
A clean environment is not just about scenic beauty—it is a foundation for good health. From the air we breathe to the water we drink and the spaces we live in, the quality of our natural environment deeply influences our physical and mental wellbeing. In today's fast-changing world, where pollution levels are rising and ecosystems are under pressure, understanding the link between environment and health has never been more important.
In this article, we will explore how the environment affects our health, what global research says, and what we can do—individually and collectively—to protect both our planet and ourselves.
1. The Air We Breathe: Invisible but Powerful
Air Pollution and Its Health Effects
Air pollution is one of the most serious environmental threats to human health. According to the World Health Organization (WHO):
99% of the global population breathes air that exceeds WHO air quality guidelines.
Air pollution comes from sources like vehicle emissions, industrial smoke, construction dust, and even indoor cooking in some rural areas. Tiny particles, called PM2.5 and PM10, can enter our lungs and even the bloodstream, leading to:
- Asthma and other respiratory diseases
- Heart problems
- Stroke
- Premature death
In children, polluted air can impair lung development, while in elderly people, it can worsen existing health conditions.
Indoor Air Pollution
Indoor air is not always safer. In developing countries, millions still use biomass like wood, dung, or coal for cooking. This causes indoor air pollution, which is linked to:
- Chronic Obstructive Pulmonary Disease (COPD)
- Pneumonia in children
- Eye irritation and headaches
2. Water: The Source of Life and Health
Contaminated Water and Disease
Clean water is a human right, yet many around the world still lack access to safe drinking water. Waterborne diseases such as:
- Cholera
- Diarrhoea
- Typhoid
- Hepatitis A
...are all linked to unclean or unsafe water.
As per UNICEF, around 829,000 people die each year due to diarrhoea caused by unsafe drinking water, poor sanitation, and hygiene.
Chemical Contaminants in Water
Even treated water can carry harmful chemicals like:
- Arsenic (from natural deposits or industrial pollution)
- Lead (from old plumbing)
- Nitrates (from overuse of fertilisers)
Long-term exposure to these chemicals can cause cancer, kidney damage, developmental issues in children, and even cognitive problems.
3. Natural Surroundings and Mental Health
Green Spaces, Blue Spaces, and Emotional Wellbeing
Access to green spaces (like parks, forests) and blue spaces (like rivers, lakes) significantly improves mental health. Research shows that spending time in nature can:
- Reduce stress and anxiety
- Improve mood
- Enhance concentration and memory
- Boost creativity
- Help manage depression
A study published in Nature Scientific Reports found that spending just 2 hours a week in nature is associated with better health and wellbeing.
In urban areas, lack of access to natural surroundings has been linked to higher rates of mental health issues and lifestyle diseases.
4. Climate Change: A Growing Health Crisis
Climate change is not just about rising temperatures. It directly and indirectly impacts human health:
- Heatwaves cause dehydration, heatstroke, and can be fatal—especially for elderly people.
- Floods and droughts affect food and water availability.
- Vector-borne diseases like malaria and dengue are spreading due to shifting weather patterns.
- Mental health issues such as anxiety, depression, and PTSD are rising in communities facing climate-related disasters.
The Lancet Countdown 2023 report states that climate change is already reversing progress in global health made over the past decades.
5. The Social Side: Who Suffers the Most?
Environmental health issues do not affect everyone equally. Vulnerable groups like:
- Children
- Elderly people
- Low-income communities
- People with pre-existing health conditions
...often face the highest risks because they have limited access to healthcare, clean environments, and the means to move to safer areas.
This makes environmental justice a key part of public health. Everyone deserves to live in a clean, safe environment—regardless of their economic or social background.
6. What Can Be Done? Practical Actions for a Healthier Environment
While large-scale government policies are important, individual actions also matter. Here’s what we can do:
At Home
- Switch to clean energy sources like LPG or induction cooking.
- Use water filters and reduce plastic bottled water use.
- Plant trees or indoor plants to improve air quality.
- Avoid burning garbage, leaves, or plastic.
In Community
- Participate in local clean-up drives or green events.
- Support eco-friendly businesses and products.
- Educate others about pollution and sustainability.
As Citizens
- Encourage rainwater harvesting and solar energy adoption in your society.
Your health and the planet’s health are deeply connected. Clean air, safe water, and access to nature are not luxuries—they are essentials. By taking care of the environment, we are also investing in a longer, healthier life for ourselves and future generations.
Whether it’s by planting a tree, switching to a reusable bottle, or choosing to walk instead of drive—every action counts. The journey to a healthy life begins with a healthy planet.
