Busting the Myth: Is Air Conditioning Bad for You?

In hot and humid climates, such as Singapore, air conditioning tends to be more of a necessity than a luxury. It offers a welcome escape from the intense heat, keeping families, businesses, and communities comfortable and productive even during the hottest days. However, there is a persistent myth that air conditioning is bad for you, potentially compromising indoor air quality and posing health risks.

In this article, we’ll explore the validity of these claims by diving into the health risks and benefits of AC. We will also share practical tips on how to create a healthy and comfortable indoor space with your trusty air conditioner.

Is Air Conditioning Bad For You? A Deep Dive

Myth #1: Lower Indoor Temperatures Make You More Prone to Falling Sick

Many people believe that air conditioning is bad for you because it increases your risk of falling sick with a cold or respiratory infection. However, this is not necessarily true. 

When used correctly, air conditioning does not directly cause illness. In fact, it helps regulate temperature, reducing the risk of heat-related illnesses such as heat stroke or exhaustion. The real concern lies in sudden temperature fluctuations between indoor and outdoor environments. Rapid changes can potentially stress the body, but simply maintaining a comfortable, consistent temperature indoors does not inherently lead to illness.

Moreover, modern air conditioning systems often include advanced air filtration and humidity control features that lead to the improvement of indoor air quality. By removing allergens, dust, and pollutants from the air, air conditioning can reduce respiratory irritants, which can help prevent illnesses. Regular aircon servicing is key, ensuring that filters are clean to prevent the circulation of more particulate matter.

Myth #2: Air Conditioning Dries Out Your Skin and Respiratory System

Another common myth about air conditioning is that it dries out your skin and respiratory system, causing irritation and discomfort. While it’s true that it can reduce humidity levels and cause dryness in some cases, modern air conditioners are equipped with features that help mitigate this.

When used properly, air conditioners can actually help maintain a balanced indoor environment by preventing excessive moisture that can lead to mould growth while also avoiding overly dry conditions that can irritate your skin and airways.

Additionally, air conditioners with built-in humidity control features can help prevent the air from becoming too dry, which is especially important for people with sensitive skin or respiratory issues. So, the misconception that air conditioning is bad for you in terms of skin and respiratory health is not completely accurate.

Myth #3: Using Air Conditioning at Night is Bad For You

You may have heard about how using air conditioning at night is bad for you, disrupting sleep or negatively impacting your health. Some also believe that cool air from the AC can lead to stiff muscles, sore throats, or even colds. However, this is largely a misconception. In truth, air conditioning can actually enhance sleep quality by maintaining a cool, comfortable temperature that helps regulate your body’s natural sleep cycle. A cool room can promote deeper, more restful sleep while preventing overheating that can lead to restless nights.

To avoid potential issues, it’s important to set your air conditioner to a comfortable and moderate temperature, ideally between 23°C and 25°C, and ensure it’s well-maintained. This will help prevent extreme cold air that could lead to discomfort while still benefiting from a cool and restful environment. So, air conditioning is not bad for you when used responsibly at night and can actually help you enjoy quality sleep.

How to Enjoy a Healthier Home with Air Conditioning

Now that we’ve cleared the air by addressing whether air conditioning is bad for you, let’s explore how to create a healthier and more comfortable indoor environment.

Choosing the Right Air Conditioner

First, you’ll need to choose the right aircon system for your home. Consider the following factors before making your purchase:

1. Air Filtration Capabilities

Look for air conditioners equipped with High-Efficiency Particulate Air (HEPA) or electrostatic filters. These are highly effective at trapping airborne particulate matter that triggers or exacerbates respiratory conditions. 

HEPA filters use a dense, multi-layered mesh of fibres to intercept and trap at least 99.97% of particles that are 0.3 microns in diameter. This includes a wide range of allergens, dust, smoke, and even some bacteria and viruses. On the other hand, electrostatic filters—made of synthetic materials like polyester—are designed to use an electrical charge to attract and trap particles. 

This is particularly beneficial for households with pets, as pet dander can be a common trigger for allergies. An aircon with a high-quality filter will significantly reduce the circulation of pet hair and other particles in the air, creating an allergen-free space for all.

2. Antimicrobial Coatings

If your household has vulnerable individuals like the elderly, young infants, or individuals with weakened immune systems, opt for air conditioners with antimicrobial coatings on their filters and coils. These coatings serve a dual purpose: they help prevent the growth and spread of harmful bacteria, viruses, and fungi within the system, and they keep the air circulating throughout your home cleaner. This provides an extra layer of protection against common airborne diseases and allergies, promoting a healthier living environment. 

While antimicrobial coatings offer an extra layer of protection, air conditioners still require periodic cleaning. Arrange for an aircon chemical cleaning once every six months to remove any accumulated dirt, dust, and mould.

3. Humidity Control Features

Air conditioners with built-in humidity control features help maintain an optimal balance, typically between 30% and 50% humidity. As outlined earlier, excessive or low humidity levels can be bad for you, which is where air conditioning comes in handy. 

Some air conditioners have a dedicated dehumidification mode, where they lower fan speed to maximise moisture extraction. This helps reduce humidity without overcooling the room. Similarly, some models come with sensors that monitor the relative humidity and adjust

4. Air Purification Features

Air conditioning with integrated air purification systems uses various technologies, such as activated carbon filters and UV-C light, to remove air particles that are bad for you. This includes smoke, volatile organic compounds (VOCs), and other pollutants. VOCs, which can be emitted from paints, cleaning products, and other household materials, are particularly harmful to respiratory health. 

For individuals living in areas with high levels of air pollution, such as near major roads or construction sites, or those who suffer from asthma, an air conditioner with built-in air purification capabilities will go a long way in maintaining a home environment that is clean and safe.

5. Low Noise Levels

Noisy air conditioning can be bad for you, disrupting your rest and productivity, increasing stress levels, and affecting your quality of life overall. Thus, it’s best to choose an air conditioner designed for quiet operation. Key features to look for include an advanced compressor design that runs smoothly and quietly. Inverter compressors, for example, adjust their speed according to cooling needs, allowing them to operate at lower, quieter speeds compared to traditional compressors that cycle on and off.

Opting for a quieter air conditioner helps ensure better sleep quality, mental well-being, and overall comfort, making it an essential feature for any home.

Creating a Healthier Indoor Space

In addition to optimising air conditioning use, there are several steps you can take to improve the overall healthiness of your indoor environment:

1. Use Non-Toxic Cleaning Products

Certain cleaning products can contain chemicals and VOCs, which can release harmful fumes and irritate your respiratory system. If you are sensitive to these chemicals, consider switching to non-toxic, eco-friendly cleaning products. This allows you to keep your house pristine without compromising your health.

2. Create a Pet-Friendly Space

While pets bring joy and companionship into our lives, they can also introduce allergens such as dander, fur, and other particles that affect air quality. Regular grooming, using washable pet bedding, and cleaning pet areas frequently can minimise their impact on your indoor environment.

3. Regularly Check for and Address Mould

Mould thrives in damp, humid areas—usually bathrooms, kitchens, and areas near air conditioners—and can lead to significant health problems. They can appear as black or green patches on walls, ceilings, or floors. Regularly inspect these spaces for signs of mould and take prompt action to eliminate it.

4. Add Plants and Greenery

Certain indoor plants, such as snake plants, spider plants, and peace lilies, are known for their ability to purify the air by absorbing toxins and releasing oxygen. Moreover, the presence of greenery has a calming effect, making your home feel more natural and peaceful. Just be mindful of overwatering, as excess moisture can contribute to mould growth.

5. Dispose of Waste Properly

Improper waste disposal can cause foul smells, attract pests, and even lead to the spread of harmful bacteria or viruses. To combat this, use covered trash bins and dispose of your garbage once or twice a day. Consider separating food waste from non-organic waste, as food waste decays quickly and needs to be disposed of more frequently. Finally, take extra care to clean areas where you store waste—this will prevent bacteria buildup and improve the cleanliness of your home overall.
