5 Health Benefits of Good Air Conditioning

Air conditioning has gradually become a modern day necessity for many of us, especially for those who live in a hot and humid city like Singapore. Situated close to the Equator and surrounded by the sea, even the rain here is humid and often leaves the air feeling thick and heavy rather than cool. According to the National Environment Agency, the average relative humidity level is 84.2%, and sometimes even reaching a full 100% on rainy days.
In fact, Singapore’s founding father Mr Lee Kuan Yew once said in an interview that the first thing he did after becoming prime minister was to install air conditioners in civil service office buildings.
“It changed the nature of civilisation by making development possible in the tropics. Without air conditioning you can work only in the cool early-morning hours or at dusk,” he said.
Indeed, a well-installed and properly maintained air conditioning system has many benefits for your home and living spaces, improving overall health and well-being for you and your loved ones.

1) Regulates humidity

Ever stepped into an air-conditioned space from the sweltering heat outdoors, and felt your frustration evaporate instantly with the moisture on your skin?
Perhaps the most conspicuous benefit of air conditioning is regulating humidity. Air conditioning works with a cold evaporator coil that condenses excess water vapour from the surrounding hot air. The moisture collected by the coil is drained and dispelled outside your home.
Humidity levels need to be regulated because an overly humid environment is a breeding ground for bacteria and harmful micro-organisms, while overly dry air can cause discomfort and aggravate skin conditions. It is also important to choose the right size and power of your air conditioner for your space. Only then will your air conditioner be effective at controlling humidity in your house and keep it within the healthy range.

2) Improves air quality

Air contains dust particles and fumes which become easily trapped inside buildings. A good air conditioning system circulates and filters air to clear these pollutants from the inside out, improving respiratory health.
This filtering effect also applies to odours, which no home owner should take lightly. More than just an unpleasant bad smell, odours are often an indicator of a deeper and more serious problem — stale air, fumes or even carelessly stored cleaning chemicals. If left unfiltered for a prolonged period, they will grow stagnant and affect your health.

3) Relieves asthma

On a related note, air conditioning also relieves allergy-induced asthma by filtering out the irritants that trigger an attack. Dust mites and mould are common culprits, both commonly found in confined spaces that are poorly ventilated.
Asthma is a chronic respiratory condition caused by inflammation of the airways, obstructing oxygen flow to the lungs. This triggers off symptoms like coughing, wheezing, shortness of breath and chest tightness.

While different people have different triggers, ranging from exercise, acid reflux to stress, allergic asthma is the most common type of asthma, especially among children. About 90% of kids with childhood asthma and 50% of adult asthma sufferers have allergies.
Allergy-induced asthma can be relieved by a well-maintained air conditioning system, which regularly removes pollutants and allergens from the air. It is especially important for families with asthma sufferers to clean and change the AC filters regularly — if not, they can actually contribute to indoor air pollution.

4) Enhances sleep

Sleeping in a cool environment lowers our heart rate and blood pressure, allowing us to fall asleep more easily and enjoy an uninterrupted night of deep sleep. A too hot (or cold) room interferes with the body’s natural temperature regulation which doctors say functions best between 18 and 24°C.
Other than temperature, sleeping in an air-conditioned room with the windows closed shuts out traffic and ambient noise from the outside environment, which is very common in Singapore due to the density of our land.

5) Boosts productivity and mood

A stable room temperature regulated by air conditioning contributes to your emotional well-being in two ways: boost your productivity and alertness with cool refreshing air, and calm you down in a consistent environment.
Instead of allowing the temperature in your home to fluctuate with Singapore’s unpredictable weather, installing an air conditioning unit can cool down your mind and body, so you can truly relax and unwind in the comfort of your peaceful home.
If you have work to do or have children cramming for a major exam, cooling down the room temperature with air conditioning helps prevent sluggishness and boosts productivity and concentration.
