We all love the joy of cooking at home rather than going out. If you’re someone who enjoys cooking, it can be an exciting experience.

Even from our early years, we’ve always preferred our mom’s homemade lunch over dining out. It’s a significant part of our cooking culture. However, one aspect we often overlook is the potential health hazards associated with the smoke in our kitchens.

While we may not pay much attention to it, the individuals who prepare our delicious meals daily are unknowingly exposed to an unhealthy atmosphere filled with kitchen indoor smoke.

These individuals may suffer from various respiratory diseases without even realizing the cause. Therefore, starting today, let’s learn the facts about this hazardous condition caused by kitchen indoor smoke and increase our awareness. So, keep reading and enjoy the journey of knowledge.

Did you know that according to the World Health Organization records, over 3.8 million deaths worldwide are caused by household air pollution annually?

Furthermore, more than 3 billion people around the globe rely on polluting energy sources. Such as kitchen indoor smoke, for cooking. Surprisingly, indoor air pollution can be even worse than outdoor air pollution, as estimated by the Environmental Protection Agency (EPA). Can you imagine why that might be the case?

Why Kitchen Smoke Gives Worst Experiences?

When it comes to cooking, many people believe that the burning process is the sole reason behind air pollution. However, air pollution in the kitchen can be categorized into two main parts:

  • Burning (heating source)
  • Cooking (from foods)

In daily cooking, people typically use different heat sources such as

  • Gas
  • Wood
  • Kerosene
  • Coal
  • Electricity.

Among these options, electricity is ranked as the energy source that generates the least amount of air pollutants during the burning process.

Unlike gas and wood, it is more efficient and requires less time for cooking. Electric energy is converted into thermal energy without burning any material, minimizing the release of contaminants.

In contrast, burning wood, gas, and coal produce significant amounts of contaminants. Such as carbon dioxide, toxic carbon monoxide, and formaldehyde.

Exposure to these contaminants can have severe consequences. Especially for individuals with respiratory conditions like,

  • Asthma
  • Pneumonia
  • Lung cancer
  • Chronic obstructive pulmonary disease (COPD)
  • Cardiovascular diseases.

Unfortunately, these conditions can become uncontrollable if there is prolonged exposure to high levels of air pollutants.

Barbeques and Grilling are the Worst kitchen smoke

In addition to the smoke generated by the energy source, the smoke released by the food during the cooking process, and the smoke absorbed by food can also be toxic to our health.

This is particularly true during barbecuing and grilling, which create an inhospitable environment in the kitchen. That’s why barbecuing is often done outside, as the resulting smoke is considered unhealthy and toxic.

Toxic Contaminants Form in Kitchen Smoke:

When discussing indoor air pollution caused by kitchen indoor smoke, we need to be aware of several air contaminants.

These contaminants include:

1. Carbon Oxides ( CO2 and CO):

Carbon oxides are common by-products of burning hydrocarbons. The levels of carbon monoxide (CO) are particularly critical as they directly impact the respiratory system.

It also can cause sudden and fatal consequences. According to records, 51% of kitchens in the United States have CO levels exceeding the EPA standards of 9 parts per million (ppm).

Also, 5% exceeds the standards for CO2 levels of 200 ppm. Although CO2 is a non-toxic gas produced by burning, in confined spaces. It can lead to drowsiness, headaches, and a “stuffy” feeling due to limited air circulation.

2. Nitrogen Oxide:

Nitrogen, the most abundant gas in the atmosphere, can generate its oxides when exposed to high energy levels, causing respiratory irritation.

Ignition of burners in the kitchen can release nitrogen oxide gas, which is a health hazard for individuals with asthma. Direct exposure to nitrogen oxides can also lead to eye irritation and associated membrane problems.

3. Particulate Matter (PM2.5):

If you are using Energy Sources unless Electricity, Always Be careful

In residential kitchens, particulate matter, specifically PM2.5, is often generated from cooking oil fumes at higher levels.

Unlike other air pollutants, PM2.5 particles can penetrate the respiratory system and enter the bloodstream, impacting various organs in a short amount of time.

When barbecuing or grilling occurs indoors, these contaminants can be found throughout the home. It is always recommended to carry out such activities outdoors for better protection.

4. Water Vapor:

You might be surprised to learn that water vapor can act as a contaminant indoors. During the daily cooking process in the kitchen, water vapor is released from food while heating or boiling.

Just like burning kitchen indoor smoke, food can also release air contaminants. These vapor droplets can settle on indoor walls and other surfaces, promoting the growth of indoor molds and leading to various diseases, even if we tend to disregard it.

Apart from these, there are several other air contaminants and factors related to food that can impact our health differently. The impact varies depending on the type of contaminant and the individual’s health condition.

Medical Conditions Coming with Bad Smoke

Exposure to kitchen indoor smoke can lead to several medical conditions, particularly for individuals with pre-existing respiratory issues. Some common health problems associated with bad smoke include:

Respiratory Infections: Inhaling smoke regularly can weaken the respiratory system, making individuals more susceptible to infections such as bronchitis and pneumonia.

Asthma Exacerbation: Kitchen smoke can trigger asthma attacks, causing breathing difficulties, wheezing, and chest tightness for individuals with asthma.

Chronic Obstructive Pulmonary Disease (COPD): Long-term exposure to kitchen indoor smoke can worsen COPD symptoms, leading to progressive lung damage and decreased lung function.

Cardiovascular Diseases: The toxic substances present in kitchen indoor smoke can also contribute to the development of cardiovascular diseases, such as heart attacks and strokes.

Understanding the potential health risks associated with bad smoke reinforces the importance of taking proactive measures to minimize exposure.

Minimizing the Hazards of Kitchen Indoor Smoke

1. Upgrade the Ventilation System:
