Why sleep deprivation is Singapore’s hidden health concern

While it is relatively easy to spot the short-term effects of sleep deprivation such as fatigue, reduced concentration and irritability, lack of sleep can also adversely affect life longevity. 

The less sleep a person gets, the worse these health effects can become, though the exact risk varies from person to person. Failure to recognise sleep problems not only delays diagnosis and treatment—it also increases the possibility of developing long-term health problems.  

Beyond these long-term health risks, insufficient sleep can also increase the risk of accidents. According to research by the US Institute of Sleep Medicine, nearly 20% of serious car crash injuries are associated with driver sleepiness, independent of alcohol consumption. 

A common misconception is that sacrificing sleep leads to greater productivity. For example, in January 2025, Channel News Asia reported that many Singaporeans struggle with sleep deprivation because the culture has long associated staying up late with productivity and success. This belief is deeply ingrained in society, where long hours and constant availability are viewed as signs of dedication. All-nighters, late-night emails, and working beyond standard office hours are often considered symbols of hard work and commitment. 

In reality, studies have shown that chronic sleep deprivation impairs attention, memory, decision-making and overall cognitive function. While working late may be perceived as a sign of dedication, it can result in reduced efficiency and lower-quality output. 

Quality sleep enhances performance, improves mood and supports long-term cognitive health. Prioritising rest is not about doing less—it is about performing at one’s best. 

The effects of sleep deprivation are not only confined to adults; it also affects children, particularly those with Obstructive Sleep Apnoea (pediatric OSA). OSA is a condition where breathing repeatedly stops during sleep, leading to poor rest and potential developmental delays, cognitive impairments and behavioral issues.  

Among adults, OSA is directly tied to an increased risk in cardiovascular and metabolic health, such as type 2 diabetes, strokes and heart attacks. 

Research indicates that children with severe OSA are three times more likely to experience these neurobehavioral challenges. 

Untreated OSA can lead to chronic health problems, including high blood pressure, elevated cholesterol levels, and increased blood sugar levels, raising the risk of diabetes. These can cause lifelong health challenges that should be addressed as early as possible.

Despite growing awareness of sleep deprivation, many solutions focus only on short-term relief, such as melatonin supplements or sleep aids. While these may offer temporary benefits, they do not address underlying issues like sleep disorders, stress management or lifestyle adjustments
