What Happens When We Breathe in Polluted Air?

In this blog post, we will discuss “what happens when we breathe in polluted air?” This article will also outline a brief description of air pollution. Then, this blog will focus in deep on how polluted air causes damage to our bodies. Lastly, this article will also throw some light on taking care when surrounded by polluted air.

What happens when we breathe in polluted air?

Every cell of your body gets affected when you breathe polluted air. Various systems are affected due to the inhalation of the poisonous chemical cocktail. These systems are as follows:

  •  Respiratory system
  •  Cardiovascular system
  •  Nervous system
  •  Digestive system
  •  Excretory system
  •  Reproductive system
  •  Skeletal system
  •  Integumentary system
  •  Immunity system

Before entering into these details, let’s look at what exactly is air pollution.

What is air pollution?

The presence of toxic elements in the air you breathe is called air pollution. These harmful elements are pollutants; they can be available in liquid droplets, solid particles or a gaseous state. These contaminants can be biological as well as chemical in nature. These pollutants, which you inhale, can originate from nature or human activities. Particulate matter (PM), SOx, NOx, VOCs, ground-level ozone are some pollutants present in the air. These contaminants can cause detrimental effects on human health.

Let’s see how this breathed polluted air affects the human body.

Which organs get affected due to breathing polluted air?

Air pollution affects you from head to toe. The systems which get affected due to breathing polluted air are as follows:

Respiratory system

Your respiratory system consists of organs and tissues that help you carry out the inhalation and exhalation process. These organs comprise your airways, lungs and blood vessels. These sponge-like lungs are responsible for absorbing a large amount of air that you breathe. In addition, they are in close contact with your blood vessels which carry out the function of oxygen transport to your whole body.

Your respiratory system is one of the systems to get majorly affected due to polluted air. When you inhale, you take in oxygen and other dangerous pollutants too. This system is vulnerable to air pollutants as it comprises a mucous membrane covering its internal surface.

Contaminants such as ground-level ozone, metals and free radicals can damage cells of your lung tissue. For example, ozone can affect the air sac of your lungs, which are responsible for the exchange process of oxygen and carbon dioxide.

Poor air quality also affects your airway tissues. The bio-activation enzymes present in these tissues transform organic pollutants into reactive metabolites. This process can be responsible for lung injuries, neuro-behavioural disorders and even breast cancer.

Particle pollution can cause inflammatory responses to your respiratory system. Therefore, such a type of pollution can be responsible for pulmonary inflammation.

Airway inflammation also affects your response to the irritants such as cold air, dust, dirt and allergens. These actions may cause impairment of lung function. This is the particular reason why there are rising cases of asthma worldwide. Coughing, sneezing, wheezing, and sore throat are other effects on the respiratory system.     

Cardiovascular system

The second-most system affected due to air pollution is your cardiovascular system. This is because the airborne pollutants, along with oxygen, gets easily absorbed into the bloodstream. As a result, such polluted bloodstream circulates in the body.

While air pollution can bring small changes in blood pressure and other blood parameters, prolonged exposure to particulate pollution can cause the acute coronary syndrome, heart failure, ischemic stroke and cardiovascular mortality. Medical researchers also noticed that cases of arrhythmias increase with a surge in air pollution levels. Contaminants such as CO, NO, SO2 and PM are responsible for such conditions.

Nervous system

The polluted air you breathe in can affect your nervous system badly. It can directly affect your central nervous system (CNS). Air pollution also causes conditions such as neuroinflammation and reactive oxygen species (ROS). Such processes affect multiple CNS pathways.

Neuroscience research has observed that when children and older citizens are exposed to polluted air, they exhibit signs of cognitive dysfunctions. There has also been a rise in the cases of stroke incidences and mortalities in recent years. This situation is all because of the degrading air surrounding you. 

Air pollution is also linked to severe signs of neurodegenerative conditions such as dementia, Alzheimer’s disease and Parkinson’s disease.

The brain health of children is affected the most. Children exposed to high air pollution can develop autism, AHDHD, lower IQ and other neurobehavioral problems. Recent studies also suggested that poor air quality can affect children’s academic performance. In addition, air pollution can lead to memory loss in kids. In the older population, air pollution can accelerate ageing.

Digestive and Excretory System

Inhaled polluted air can create problems in your digestive and excretory systems too. In addition, air pollution can cause gut inflammation causing damage to good bacteria. Thus, poor air quality may not make you feel “light and fresh” every morning.

 Air pollution is also responsible for other gastrointestinal disorders. Infection of the gastrointestinal tract due to polluted air can also cause a risk of obesity and diabetes. Poor air quality is also responsible for irritable bowel syndrome (IBS).

Reproductive system

Air pollution is responsible for varied hormonal fluctuations in your body. Multiple studies in medicine have concluded that air pollution affects the fertility rate. Unfortunately, it also leads to birth complications, infant congenital disabilities and stillbirths.

It has also been reported that semen and sperm quality gets severely affected due to air pollution. Exposure to high dioxin levels can disrupt the healthy growth of the womb and lead to spermiograms in males. 

Skeletal and Integumentary System

Air pollution not only affects your organs and tissues but also affects your skeleton. Bones in your body can get brittle. Radioactive pollution also affects your bones and joints. Pollution can cause swelling of bone joints and even bone cancer.

Skin also acts as a giant sponge that absorbs all the toxins. As a result, it can lead to age spots, chronic skin inflammation, ageing, pimples, acne and psoriasis. Air pollution also has a direct impact on hair health. If you live in any region having poor air quality, you can experience hair fall. In addition, air pollution can affect scalp health and hair follicles.

Immune system

As mentioned earlier, bad air quality affects every cell of the body. As a result, our immunity system gets compromised. As a result, you can sometimes feel dizzy, can get nose and throat infections. Your eyes may also get dry and itchy. As a result, you can be more susceptible to infections. Again, this all happens due to a compromised immune system.

Well, this is what happens when you breathe in polluted air. Unfortunately, the effects sound too severe and problematic. But, not to worry, you can avoid all these issues by following some simple steps. So let’s look ahead to see what it is.

What to do next?

A sustainable lifestyle is key! Here’s how you can have:

  • Promote local produce:

 Buy local products more often. In this way, you are reducing the carbon footprint of logistics. Local foods also boost your metabolic activities, strengthening your immunity system.

  •  Good mask:

 It’s anytime better to invest in some good masks rather than paying bills on medicines and hospitals.

  •     Good diet

A well-balanced diet can do wonders for your body. First, make sure you are constantly hydrated. Drink at least 3-4 litres of water daily. Include anti-inflammatory foods in your diet.

Anti-inflammatory foods which I will suggest are:

  • Turmeric
  •  Blueberry
  •  Leafy Vegetables
  •  Beetroot
  •  Avocado
  •  Celery
  •  Almonds
  •    Carrots
  • Berries
  •   Broccoli
  •  Good external hair and skincare:

As much as it is necessary to stay fit inside, it is also essential to take care externally. Brush your hair frequently. Oil massage and brush your hair twice a week. Wash your face twice a day. Also, brush your teeth twice a day. Do cut your nails often.

  • Exercise:

Physical and breathing exercises can help you to increase your lung capacity. You can perform Surya namaskars to boost your immunity and breathing abilities. Breathing exercise or pranayama can help to strengthen your respiratory muscles.
