Does air quality get worse with Heat?

In this blog post, we will discuss “does air quality get worse with heat?” Firstly, this blog will briefly describe the basics of air pollution. Secondly, it will emphasize how and why does air quality get worse with Heat? Additionally, the article will also share the effects of such pollution. Lastly, this report will also provide solutions to fight air pollution.

Does Air Quality get worse with Heat?

Yes,  air quality gets worse with Heat. Heat is responsible for increasing air pollution in the following ways:

  • Weather conditions
  • Transformation of primary sources air pollutants into secondary
  • High atmospheric pressure

Before diving into its details, let’s first see what air pollution is all about.

What is air pollution?

The introduction of harmful agents into the atmosphere is known as air pollution. The toxic agents are known as pollutants. These pollutants are derived from natural and human activities, and they can be chemical or biological.

Major pollutants present in the air are particulate matter (PM), ground-level ozone (O3), NO2, SO2, and CO. Air also has lead, allergens, bacteria, viruses and volatile organic compounds (VOCs).

Besides climate change, air pollution has become a significant environmental risk to human health. 

Therefore, striving towards minimising air pollution can also help to improve climate change mitigation efforts. In addition, reducing emissions will enhance the quality of air.

WHO has suggested some revised guidelines on 22 September 2021 to improve the overall air quality. This organisation has decided to implement permissible limits of the earlier significant pollutants.

These permissible limits of ambient air quality are as follows:

PollutantsHourly mean concentration (ug/m-3)Annual mean concentration (ug/m-3)
PM2.5155
PM104515
NO22510
SO240
CO4
O38 hour: 100Peak season: 60

Let’s know in depth how and why does air quality get worse with the heat.

How and why does air quality get worse with the Heat?

Heat parameters play a significant role in determining the quality of the air you will breathe in. You might have observed the air quality warnings popping on your notifications or weather forecast channels while waiting for the warm temperature updates during summertime. Well, some bad news for the summer-loving people—even summer times are not spared by the poor quality levels.

Heat is responsible for increasing air pollution in the following ways:

  • Weather conditions
  • Conversion of primary sources pollutants into secondary ones
  • High atmospheric pressure

Let’s look further at what does all mean

Weather conditions

During the summer season, the weather around you is hot and sometimes humid. These conditions are responsible for increasing all types of pollutants originating from primary sources. Due to increased Heat, you naturally tend to use air conditioners more often in your homes and cars—increased power usage results in increased particulate and other types of pollution. As per the US White House report, climate change clubbed with longer warm periods results in a more significant generation of plant-based allergens such as pollens.

Besides, a combination of dry, intense heatwaves or nearly drought-like situations with hot winds can be more problematic for you. These long spells of heatwaves can dry all vegetation and forest cover near you. When hot winds brush the branches of the trees against each other, it triggers wildfires. A massive amount of wildfires can cause high amounts of particulate pollution. This can get transported by winds to other neighbouring cities as well.

Transformation of primary sources air pollutants into secondary ones

The high amount of heat levels become favourable for primary airborne pollutants to develop further. Pollutants released from primary sources such as nitrogen dioxides and oxygen, when combined in sunlight and high temperatures, form ground-level ozone. While ozone in the atmosphere is good as it filters out ultraviolet rays, the ground level ones can be responsible for causing deadly lung and heart diseases.

Such produced pollutants are called secondary pollutants. These secondary particles, photochemically produced by sunlight, contribute to 90% of the total particulate matter.

High atmospheric pressure

Heatwaves cause high atmospheric pressure. Such pressures create a stagnant environment. If this is joined with light winds and minimal precipitation, pollutants don’t get cleared from the air and accumulate right above the land surface.

Worst air quality due to Heat can lead to adverse human health effects. It can cause various respiratory ailments such as decreased lung functionality, asthma, pollen allergies and cardiovascular diseases like stroke, chest pain, etc. In addition, it can lower productivity levels. Let’s see in deep how these pollutants affect you.

What are the health effects of air pollution?

Environmental studies have proved that PM2.5 and PM10 have caused relevant harm to public health. Both pollutants can deeply penetrate inside your lungs. PM2.5 can enter your bloodstream, which results in various respiratory and cardiovascular ailments. It can also affect other organs. WHO has declared these two pollutants as carcinogenic elements.

The detailed adverse effects on human health are as follows:

  • Respiratory ailments: COPD, asthma, bronchitis, whooping cough, common cold and cough, throat infection, lung cancer, chest congestion, sinus congestion, etc. 
  • Cardiovascular diseases: Heart attack, cardiac arrest, chest pain, heart blockage, stroke, etc. 
  • Mental disorders: Anxiety, insomnia, depression, low productivity, irritation, Alzheimer’s disease, Parkinson’s disease, dementia, brain stroke, paralysis, etc.

The other effects of air pollution are low sperm counts, low reproductive ability, infertility and congenital infant disabilities.

To prevent yourself from such deadly ill effects, I have shared solutions to reduce air pollution in the next section.    

What can I do to protect myself from air pollution?

I will elaborate on some of the measures to protect yourself from air pollution.

Personal Hygiene

You can also fight the effects of air pollution by maintaining personal hygiene:

  • You can cut your nails short to avoid the accumulation of dirt. 
  • You can also practice mouth gargling after coming home to free your mouth from unwanted guests.
  • You can also brush twice a day to keep airborne infections at bay.
  • You can also take steam therapy at home to cleanse your lungs.

Quit Smoking

Smoking cigarettes, hookahs (shisha), electric vape or any other types of cigars are not at all suitable for your health. It’s best to stop smoking. Active and passive smoking provides the direct entry of harmful pollutants into your body. This causes the risk to your respiration and other organs dependent on it. 

Physical Exercise 

Physical activities have many benefits to your body. It not only improves your stamina and immunity levels but also helps to increase your lung capacity. Yoga, sanas, swimming, running, cycling, brisk walking and dancing are some of the best forms of exercise to improve your health.

Breathing Exercise 

The majority of people in the world don’t breathe properly. However, correct breathing techniques can keep illnesses due to air pollution at bay. A pranayama is a form of yoga asana which helps to improve breathing methods and lung functionality.

Some of the pranayama types that help you fight air pollution are Kapalbhati, Anulom Vilom, Chandra Nadi, Surya Nadi and Bhastrika. It is strongly recommended to learn this art of breath from a well-certified yoga trainer. 

You can also increase your lung muscles by simply taking a deep breath and holding it for a count of 10. Then, slowly breathe out the air. If you can keep your breath for a longer time, then you have good lungs health.

Good diet 

Always go for a well-balanced diet to remain fit and strong. Consistent eating of junk and fast food will increase the risk of obesity and other diseases. In addition, such people are more vulnerable to the adverse effects of air pollution. Instead, add more fresh veggies and fruits to your diet. Also, you can consume less meat to minimise carbon footprints.

You can also add anti-inflammatory foods as these types of food help to cleanse your lungs effectively. Anti-inflammatory foods which I recommend are: 

Immunity booster drinks

You can do your immunity booster drinks by using readily available items in your kitchen. Immunity booster drinks help to cleanse your lungs. Some of the DIY immunity booster drinks are as follows:

  • Take a glass of warm white milk. Add half a teaspoon of turmeric powder to it. Also, add two strands of saffron to it. Drink it at night before sleeping. You will get good sleep, and you will be relieved from chest congestion. 
  • Boil water by adding half cinnamon stick. Drink the spice-infused water once a day. Your sinuses would be cleared up. 
  • Buy an excellent green tea. Prepare a green tea by following the packet instructions. Have it whenever you feel irritation in your throat. 
  • Take some crushed 1 or 2 peppercorns, a half-inch of a blade of lemongrass and 1 inch of grated ginger and half a teaspoon of turmeric powder. Add everything in one glass of boiling water and reduce it to half a glass. Drink two tablespoons of this spice-infused warm water every after three hours. Adding honey is optional. 
  • You can also drink warm water and add honey if you want. Honey helps to relieve throat irritation.

Use Mask

Mask can prevent you from inhaling the polluted air. You would be able to work in contaminated areas without any fear of allergy infections and stress.

How can I individually reduce air pollution?

You can always try your level best to minimise air pollution. The following are the methods to reduce air pollution at an individual level.

Plant Trees

Encourage tree plantation drives amongst the communities. You can be a green saviour of your region. Trees are the natural air purifiers of the environment, and it supplies us with clean air.

Municipal councils or the local authorities can develop urban forests to increase the green cover of the locality. They can also plan to create vertical green walls to improve oxygen levels of the region naturally. But don’t forget to plant only indigenous trees. 

Human/ religious celebrations in eco-friendly ways 

Nowadays, many couples celebrate gender (of their baby) revealing parties by bursting firecrackers. But, unfortunately, these firecrackers can transform into massive wildfires if they are burst near trees.

Thus, you can celebrate such celebrations by planting trees in your nearby barren land. Bursting firecrackers on any religious, festive or personal occasion are only going to harm your loved ones. 

You can also celebrate Christmas by not cutting Christmas Trees. Instead, you can buy artificial ones and use them in the coming years too.

Discourage Plastic

Single-use plastic has been one of the major concerns in the environment. Plastic pollution indirectly contributes to the degradation of air quality. Plastic, when burned, releases various toxic gases such as dioxins into the air.

Encourage alternative use of the plastic product. For example, you can wear a cloth bag for shopping. You can also carry your travel cutlery set to a restaurant. Additionally, you can take your water bottle instead of purchasing a packaged drinking water bottle every time.

Use of public transportation 

Increase the use of public transport to reduce air pollution and traffic congestion. You can also try carpooling or the cab sharing option. Then, you can also use bicycles instead of scooters. Lastly, you can always opt for walking a shorter distance. 

Alternative use of fossil fuel

It would be best to try switching to other fuel alternatives. For example, don’t use wood for the fireplace. Instead, you can wear multiple layers of clothes for warmth. In this way, you can conserve energy. Additionally, you can also install solar panels on house roofs to convert solar energy into electricity. 

You can also buy electric and hybrid vehicles to minimise tailpipe emissions. Finally, propose or discuss a plan with your mayor or any relevant local authority to promote your region’s renewable energy sector.

Reduction of personal carbon footprints

You can also keep a check on your carbon footprints. For example, you can delete unwanted photos, videos or emails from clouds and email boxes as and when possible. Unfortunately, this unwanted stuff takes a lot of energy, which indirectly contributes to air pollution.

You can also switch off the lights and electrical appliances of the vacant rooms. Try buying local products instead of imported ones. Be vocal about them. You can also discover your own country rather than travelling to different ones.

Create Awareness

Air pollution is unpredictable; air pollution in your vicinity can affect people living in Asia and vice-a-versa. However, you can create public awareness about air pollution amongst your community by teaching and interacting with your kids about the importance of good air. 

Educate youth by telling them the ill effects of poor air quality. Then, let your country’s future know that they deserve a better place to live!

How can the local authorities improve the air quality of your region?

You can always observe the changes happening in your surrounding nature. If you experience bad air quality or any activities producing air pollution, you can always concern relevant local authorities or the mayor.

Here are some methods which local authorities can do.

Proper disposal of waste 

Improper solid waste management of an area is an invitation to many diseases and infections. In addition, burning solid waste in public can cause air pollution, although such practices are rare in the US. 

The wastes are mainly disposed of in the engineered landfills and recycled before final disposal to landfills and waste incinerators. 

In addition, waste incinerators help to convert waste into energy.

However, many researchers have claimed that gasification technology or waste-to-energy technology may release harmful gaseous contaminants. Thus, it is necessary that waste collectors rigorously segregate the waste before sending it to waste incinerators. 

The best solution is to minimise waste at a personal level. Statistically, 70% of the waste generated can be recycled effectively. Thus, strive to recycle your waste at a personal level as much as possible.

Reducing air pollution from agriculture

Stubble burning is still practised in some parts of the US. This event contributes to the degradation of air. Local authorities can help farmers convert this waste into cattle fodder or be transformed into pellets as fuel. In addition, farmers should stop the usage of harmful pesticides or fertilisers to decrease air pollution.

How can I reduce indoor air pollution?

Maintaining household or indoor hygiene

You can decrease poor air quality by adequately maintaining indoor hygiene. For example, you can frequently clean your cupboards and open decks to avoid an accumulation of dust particles. You can then vacuum your carpets and sofas at least twice a week. 

Make sure your doggies and cats are well-groomed. Use chimneys and exhaust fans in kitchens. You can also install an exhaust fan in washrooms. Always make sure you are keeping your house well ventilated. 

Keep doors and windows open when possible. Maintain the health of electric appliances such as heaters, humidifiers, AC, fans, air ducts and so on at regular intervals of the year. Avoid overuse of strong perfumes or strong scented candles indoors. You can additionally use indoor plants to make your indoors more lively and fresh.

Indoor plants

Indoor plants do the same work as outdoor ones- they help to purify indoor air naturally. These indoor plants are also easy to maintain.

The indoor plants which I recommend are as follows: 

Air purifiers

Air purifiers help to improve indoor air quality. The risk of getting air pollution-related diseases decreases due to the use of air purifiers. Air purifiers having good HEPA filters do an adequate job of filtering pollutants.

Air Purifiers I recommend are as follows:

NameWhy I recommend it
Blueair Pro XL Air Purifier99.7% of airborne pollutants such as mould, allergens, smoke particles and pollens are captured. 
AIRMEGA 400SReduction of 99.97% of particulates of 0.3 microns. Also responsible for reducing more than 99% of VOCs, NH3 and CH3CHO.Washable and permanent pre-filters are available

Frequently Asked Questions (FAQs): Does Air Quality get worse with Heat?

Is air quality worse when it’s hot?

Yes, air quality is worse when it’s hot. Air quality deteriorates when temperatures increase. The toxic gases produced from different sources react with sunlight to generate poor air quality.

Why is air quality worse in the summer?

Yes, air quality is worse in the summer. During the summer months, the Heat and radiations generate more toxic elements when combined with the existing pollutants, pollens and mould. These conditions make the air quality worse in summer.

Does climate change worsen air quality?

Climate change certainly contributes to air pollution. Higher temperatures increase allergens, pollens and other harmful agents. In addition, higher temperatures related to climate change are responsible for rising in another hazardous pollutant, known as ground-level ozone. Such conditions affect human health as it becomes difficult to breathe good air.

Does humidity make air quality worse?

Yes, humidity affects air quality. High levels of humidity increase the levels of harmful chemicals in the air. It also promotes the growth of allergens, dust mites in your homes. However, low humidity levels are also not good for your health. Respiratory diseases such as asthma and bronchitis prevail in environments having low humidity.

How do heat and air quality affect jobs?

Air quality lowers your productivity levels and makes you sluggish all the time. An increased amount of heat levels at the same time can make you stressed and irritated all the time. Such a combination can force you to work for fewer hours, thus reducing your daily income.

Should I exercise in bad air quality?

No, it is strongly recommended to avoid outdoor physical activity when the air quality levels are unhealthy. Venturing out in polluted air can make you ill, and you might be at risk of several lung and heart diseases.
