The environment we live in has a significant impact on our human health.
From the foods we eat and the water we drink to the air we breathe and the places we visit, our environment plays a pivotal role in maintaining our well-being. Unfortunately, more and more research is showing that aspects of our environment are having a detrimental effect on our health.
Nature’s influence on our health is a broad topic, so it can be overwhelming to navigate. That’s why it’s important to be aware of how different aspects of our environment affect us. In this article, you will learn about the ways in which nature affects your health, including air pollution and exposure to toxins. You will also learn about positive forms of contact with nature such as spending time in green spaces and being active outdoors.
By understanding these relationships between nature and health, you can make informed decisions when it comes to protecting both your physical and mental well-being.
Pollution and Disease
Living in a polluted world has far-reaching effects on our physical and mental health. The most obvious and direct consequence of air and water pollution is an increase in infections and diseases. Poor air quality, contaminated water, and other forms of environmental damage can lead to a range of respiratory illnesses, digestive issues, immunodeficiencies, cancers, heart disease, reproductive problems, neurological disorders, birth defects, and more.
Environmental pollution does not just put people's health at risk—it also affects ecosystems worldwide. Each ecosystem has its own balance of plant and animal life that affects the overall sustainability of that environment —and thus our own health. Fish migrating from polluted rivers to lakes can spread toxins throughout a water system; plants may be unable to reach their full potential if the soil is contaminated; birds can carry pathogens from one place to another through their flight paths. As these environmental changes take place around us, the risk of human exposure to disease rises as well.
It's important to remember that environmental pollution doesn't just affect our physical health—it can have mental health consequences as well. Stress caused by living in a polluted environment or worrying about becoming ill due to environmental pollutants can lead to anxiety and depression. Taking action to reduce our impact on nature by adopting sustainable practices is key for protecting both the environment—and ourselves—from harm.
Climate Change and Human Health
No matter your age, gender, or background, climate change affects all of us and our health. We breathe in the same air, drink the same water, and eat the same food, so it’s inevitable that our bodies are affected by changes in the environment.
From air pollution to extreme weather events, climate change-infused environmental stressors can have a severe impact on one’s health and well-being. Here are a few key effects of climate change on human health:
Air pollution: increasing carbon dioxide concentrations in the atmosphere leads to higher levels of ozone and other pollutants that can cause respiratory problems.
Heat waves: prolonged periods of hot weather can cause heat exhaustion but may also lead to more serious conditions like heat stroke.
Food insecurity: rising temperatures and changing weather patterns make it more difficult to produce crops, leading to food shortages and malnutrition.
Vector-borne diseases: warmer temperatures create a more favorable environment for disease-carrying insects to thrive and spread illnesses like malaria, dengue fever, and Lyme disease.
Climate change is impacting both physical and mental health now—and unfortunately, these effects will continue if we don’t act fast by doing our part in reducing our carbon footprint.
Mental Health and Nature
Nature not only has a physical effect on our health but also has an immense influence on our mental health. Research has shown that spending time in nature can stress, anxiety, and depression. A study conducted by the University of Rochester Medical Center found that people who lived within a mile of green space reported improved self-esteem and overall mental health.
Not only does nature provide physical activity, but it can also be a form of therapy for many individuals. Spending time in nature away from city noises and distractions can give us the chance to reflect, relax and just enjoy being outside. The quiet can help to provide clarity and clear thoughts, improving focus and creativity. Taking a break from the hustle and bustle of everyday life to connect with nature is beneficial for our physical and mental health.
Surrounding yourself with plants can also reduce stress levels. A study published in the Journal of Physiological Anthropology showed that having plants around can decrease cortisol levels (a hormone related to stress), as well as blood pressure in order to provide calming effects.
Air Quality and Health
Air quality is one of the major factors impacting your health, as poor air quality can worsen existing conditions and lead to a number of symptoms.
Pollutants
Air pollutants come from combustion sources such as car exhaust, industrial plants, and burning coal. These pollutants can cause respiratory issues such as asthma, coughing, wheezing, and chest tightness. Longer-term exposure to these contaminants has even been linked to heart disease and stroke.
Ozone
High ozone levels can irritate your lungs and throat, making it harder to breathe. In extreme cases, ozone levels may even trigger asthma attacks. Ozone clouds form in areas with high air pollution when pollutants like nitrogen oxides and hydrocarbons mix in the presence of sunlight.
Not sure if you need to be concerned about air quality? Here are a few signs that indicate it's time to take action:
Do you or someone close have ongoing respiratory illnesses or allergies
You’re noticing more irritability or coughs
Your local area has noticeable smog, especially on hot days
As with most health concerns, prevention can go a long way toward keeping you healthy. Air quality reports are available online - so check them before you plan any outdoor activities.
The Benefits of Natural Light Exposure
It is no surprise that one of the most important benefits of natural light exposure is improved physical health. Studies have reported that people who keep their windows open and get regular exposure to natural light on a daily basis are less likely to suffer from depression, obesity, diabetes, and even cancer.
The greater the exposure to natural light, it seems, the less likely you are to suffer from one or more of these conditions. Moreover, natural light has been proven to reduce blood pressure levels, while also helping boost cognitive performance by increasing alertness and concentration.
Additionally, exposure to natural light can help improve our sleep patterns and circadian rhythm. Some studies have shown that people who get regular sunlight throughout the day tend to fall asleep quicker and stay asleep longer than those who don't. This improved sleep pattern can ultimately lead to an overall better sense of well-being during waking hours as well as better quality physical health in general.
The Role of Green Spaces in Well-Being
Studies have shown that time spent in green spaces, such as parks and gardens, can have a positive effect on mental health. Whether it’s simply sitting on a park bench, going for a walk, or participating in activities like yoga or Tai Chi outdoors - spending time in nature has been linked to greater life satisfaction and improved cognitive functioning.
Research suggests that the key to these benefits lies in something called ‘attention restoration theory’ (ART). This idea centers around the concept of ‘involuntary attention’, which is when we focus on something without actively trying to do so. The sounds and sights of nature help to activate this unconscious mental state, allowing our brains to relax and reboot.
The physical environment also plays an important role in our well-being; as humans, we respond reflexively to elements like humidity and temperature. We are naturally drawn towards comfortable environments that stimulate us without overwhelming us; studies suggest that being in nature can help us achieve this balance of stimulation while also providing comfort.
Green spaces can be used to de-stress, build resilience, and foster creativity - all important factors when it comes to maintaining good mental health. So next time you need some downtime from your busy life - why not take some time out in nature?
Conclusion
Nature has an undeniable effect on human health, and we should take this seriously when it comes to our well-being. From air and water pollution to climate change, environmental contamination has the potential to cause physical ailments and mental health issues.
To secure our health and that of the planet, we must educate and inform ourselves about the consequences our lifestyles have on the environment. Governments and citizens alike should strive to understand environmental vulnerability when making decisions and strive to protect ecosystems, both near and far, to reap the benefits of a healthy environment impacting our overall health
