Why sleep matters and how much of it you need

Sleep is an essential function that enables our body and mind to recharge and stay alert when we are awake. Healthy sleep plays a crucial role in helping our body remain healthy and prevent illnesses.

According to research, most adults require at least seven hours of nightly sleep, while children and teenagers need significantly more sleep, especially if they are younger than five years old.

In such a fast-paced busy world nowadays, we often downplay the importance of sleep in our daily lives, hence there is a lack of focus on optimizing our night-time sleep. As a result, Singapore is the 3rd most sleep-deprived city out of the 43 cities according to a recently published report.

Long-term effects of poor sleep quality

Poor sleep quality may come as a result of various environmental and behavioral factors including uncomfortable sleep environment, sleep deprivation, poor bed-time routine, stress, anxiety, etc.

Long-term poor sleep quality poses serious risks of many health issues and has a lot of negative impact on our health. Some of these negative effects include:

Impaired cognitive function

Without enough good sleep, your brain struggles to function properly. This leads to poor attention span, impaired memory, difficulties with concentration, problem-solving, and decision-making.

Weakened immune system

A lack of quality sleep weakens your immune system, which makes your body more susceptible to infections and lower its ability to defend against illnesses and diseases.

Risk of chronic diseases

Long-term poor sleep quality has been linked to an increased risk of having weight gain, obesity, type 2 diabetes, high blood pressure, cardiovascular diseases, and certain types of cancer.

Mental health disorders

Having a lack of good quality sleep has been linked to the development and increased severity of mental health disorders such as depression, anxiety, bipolar disorders, and an increased risk of suicidal behaviors.

Having trouble sleeping? This may be the reason

It comes as no surprise that our sleep quality is greatly influenced by our sleep environment. Noise and light levels, temperature, mattress and bedding, and comfort are often referred to as common factors that play a role, major or minor, in affecting our sleep quality.

However, one key factor that is less often discussed, but may be amongst the biggest culprits for your trouble sleeping, tossing and turning, and poor sleep quality, is poor indoor air quality. In fact, a recent study done by a group of esteemed American researchers revealed that exposure to harmful indoor air pollutants in the sleep microenvironment (bed) can negatively impact our sleep quality.

How poor indoor air quality cause poor sleep quality

Poor indoor air quality is when the air in your home is contaminated with pollutants, allergens, or other harmful substances that may affect your health and impact your sleep quality. Some common indoor air pollutants and allergens that can negative affect your sleep quality include:

Dust Mites

Mold Spores



Pet Dander

Skin Flakes


PM2.5 & PM10



These indoor air pollutants and allergens, when inhaled through our nose and mouth, can have a negative effect on our health and negatively impact our sleep. Here is why they may cause poor sleep quality:

Indoor allergies

Exposure to these harmful indoor allergens can trigger allergy symptoms like sneezing, runny nose, coughing, sore throat, etc. that can disrupt your sleep.

Sleep disorders

Studies show that exposure to Particulate Matter PM2.5 and PM10 increases the risk of sleep disorders like sleep apnea, and difficulty falling/ staying asleep.


Indoor air pollutants like smoke, VOCs, strong odors, and unpleasant smells, can cause irritation and discomfort, making it difficult to fall and stay asleep.
