Combat Air Pollution To Prevent Harmful Health Effects

The nose is the first line of defence against air pollution, filtering, warming and humidifying the air we breathe. However, air pollution can damage this natural defence mechanism, causing swelling of the nose lining and congestion. To protect your nose from air pollution in open air, you can use protective barriers such as masks, nasal filters and nasal sprays. Nasal filters and masks can help reduce exposure to air pollutants and allergens, although their efficacy depends on their design and material. Saline nasal sprays can help wash away trapped air pollutants, providing relief from congestion. Additionally, staying informed about air quality, avoiding outdoor strenuous activity during high pollution levels, and keeping nasal passages moist with saltwater nasal washes are recommended.

Use a saline nasal spray to wash out pollutants

Saline nasal sprays are a great way to wash out pollutants from your nose. Saline is a simple mixture of salt and sterilized water. The solution used in nasal sprays is isotonic, meaning it has the same saline concentration as that naturally found in the human body.

Saline nasal sprays are available over the counter at most drug stores and are generally inexpensive. They are also available in online stores. You can also make your own saline nasal solution at home. To make the solution, mix 3 teaspoons of non-iodized salt (kosher salt with no additives is best) and 1 teaspoon of baking soda. Store this mixture in a small clean jar. When you are ready to use it, mix a teaspoon of the mixture into 8 ounces of distilled, sterile, or previously boiled and cooled water. You can also combine 1/4 teaspoon of non-iodized salt with 1 cup of distilled water and mix to dissolve. Place in a sterile squeeze bottle, and discard the contents after 24 hours.

Saline nasal sprays are a safe treatment and most people do not experience side effects. However, there is a small chance of developing mild but bothersome problems, such as mild irritation. Preservatives used in certain brands can also cause allergic reactions in some people.

To use a saline nasal spray, follow these steps:

• Sit or stand in an upright position.
• Gently blow your nose to clear any debris from your nostrils.
• Close one nostril by pressing your finger against it.
• Place the tip of the spray bottle into the open nostril.
• Close your mouth.
• Inhale slightly as you simultaneously squeeze the spray bottle.
• Repeat the process for the other nostril.

Wear a face mask with a filter to block particles

Face masks have become a common sight in recent years, with the COVID-19 pandemic making them a necessity for many. But beyond their use in preventing the spread of respiratory illnesses, they can also help to protect against air pollution.

When considering how to protect your nose from open-air pollution, wearing a face mask with a filter is an effective method. The nose is the first line of defence against pollution, filtering, warming, and humidifying the air we breathe. However, air pollution can damage this natural filter, so additional protection is beneficial.

There are various types of face masks available, each offering different levels of protection. Surgical masks, for example, are designed to protect against large droplets, such as those from a cough or sneeze, but they are too loose-fitting to guard against all germs and small particles. They are also not meant to be reused. To enhance the protection offered by a surgical mask, it is possible to wear a cloth mask over it. Alternatively, you can knot the ear loops and tuck in the extra material to create a tighter fit.

For protection against smaller particles, an N95 respirator is a better option. These masks are designed to fit tightly around the face, providing a seal around the nose and mouth, and are highly effective at filtering out airborne particles, capturing at least 95% of them. This includes the smallest particles, which are the most difficult for masks to capture. The N95 respirator is, therefore, a good choice for protection against air pollution.

Personalised nasal filters are another innovative solution. These small devices are placed inside the nose and are designed to conform to the unique anatomy of the wearer's nasal passage, ensuring a secure and comfortable fit. They can be used to specifically filter out inhaled environmental contaminants, allergens, and microorganisms, depending on individual needs. This technology has also opened up new possibilities for drug administration, allowing for the targeted delivery of treatments such as pain relievers.

Avoid outdoor activities during high pollution

Outdoor air pollution is a significant environmental health problem, causing an estimated 4.2 million premature deaths worldwide each year. The World Health Organization (WHO) reports that 9 out of 10 people globally breathe polluted air, which can have detrimental effects on human health. As the nose is the first line of defence against air pollution, it is crucial to take precautions to protect yourself when outdoors during high pollution levels.

One way to avoid the harmful effects of outdoor air pollution is to limit your exposure by reducing outdoor activities. This is especially important for vulnerable groups, including children, pregnant individuals, the elderly, and those with pre-existing health conditions such as respiratory or cardiovascular diseases. By avoiding prolonged periods outside when pollution levels are high, you can minimize the amount of polluted air you inhale. Check the air quality index (AQI) or air-pollution maps to stay informed about the daily air quality in your area. Public health websites and apps can also provide valuable information about the air pollution levels and associated health risks.

If you must go outside during periods of high pollution, consider wearing a protective face mask with a filter that can effectively remove fine particles and harmful gases. Personalized nasal filters, designed to fit snugly and comfortably in the nose, offer a more tailored solution to blocking inhaled contaminants, allergens, and microorganisms. These innovative filters can be customized to meet individual needs and can even facilitate targeted drug administration.

In addition to wearing protective gear, try to avoid peak traffic times if you must drive. Keep your car windows closed to prevent exhaust fumes from entering the vehicle. By taking these precautions, you can help safeguard your health and reduce the negative impact of air pollution on your body, particularly your nose, which plays a crucial role in filtering the air you breathe.

Check air quality reports and health warnings

It is important to stay informed about the air quality in your area to protect yourself from the harmful effects of air pollution. The Air Quality Index (AQI) is a system used to warn the public about dangerous levels of air pollution. The AQI tracks ozone (smog) and particle pollution, as well as four other common air pollutants.

You can find information about the daily AQI for your area in newspapers, on local radio and TV stations, or by checking a weather app on your phone. Websites like AirNow.gov and WAQI.info also provide real-time air pollution data for specific cities and countries. These websites use maps to show how pollution levels change and move throughout the day. The AQI values are ranked on a scale from 0 to 500, with values at or below 100 considered safe for the public. Values above 100 indicate unhealthy air quality, and the higher the number, the greater the health risk.

By staying informed about the AQI, you can take the necessary precautions to protect yourself and your loved ones from the harmful effects of air pollution. This is especially important for children, teens, the elderly, pregnant women, and individuals with asthma, lung diseases, diabetes, or cardiovascular disease.

In addition to checking the AQI, it is also important to be mindful of any health warnings related to air pollution. These warnings may be issued by local health authorities or environmental agencies and can provide specific guidance on protecting yourself during periods of high air pollution.

Avoid indoor pollutants like tobacco smoke

Exposure to tobacco smoke, especially secondhand smoke, is a serious health risk. Tobacco smoke is a major contributor to indoor air pollution and has been linked to a range of adverse health effects, including respiratory illness, eye and throat irritation, allergies, and even lung cancer. Children are particularly vulnerable to the harmful effects of secondhand smoke, which can trigger asthma attacks and increase the risk of ear infections.

To avoid indoor pollutants like tobacco smoke, it is important to take preventative measures. If you are a smoker, consider quitting smoking or, at the very least, refrain from smoking indoors. If others around you smoke, kindly request that they do not smoke inside your home or in enclosed spaces where you spend time. It is important to communicate your concerns about the health risks associated with secondhand smoke exposure.

Additionally, proper ventilation is crucial. When people are smoking indoors, ensure that the area is well-ventilated by opening windows or using exhaust fans to reduce the concentration of smoke and pollutants. If possible, avoid spending prolonged periods in poorly ventilated spaces where smoking occurs, such as indoor smoking cafes or specific rooms where smokers tend to gather.

You can also invest in air-purifying devices to improve indoor air quality. Air purifiers with HEPA filters can help capture and reduce tobacco smoke particles and other indoor air pollutants. Regular cleaning of surfaces and fabrics can also minimize the buildup of smoke residue and help maintain healthier air quality.

Lastly, be mindful of your clothing and personal belongings. Tobacco smoke particles can adhere to your clothes, hair, and belongings, transferring pollutants to other spaces you occupy. If you have been exposed to tobacco smoke, consider changing your clothes and washing your hands, hair and skin to remove any lingering smoke particles.
