Singaporeans are terrible at sleeping

- Singaporeans sleep just over six hours of sleep on both weekdays and weekends, against the recommended eight

- Four in 10 Singaporeans admit their sleep has worsened in the last five years, with 65% experiencing daytime sleepiness

- Perceived high costs of sleep consultation and treatment, and downplaying the seriousness of sleep problems hinder Singaporeans from seeking professional medical help

Singaporeans are among the world’s worst sleepers, getting just 6.3 hours of sleep on the weekdays and 6.7 on the weekend, lower than the global average of 6.8 and 7.8 hours respectively and the daily recommended eight hours. This finding was announced by Royal Philips, a global player in health technology, in the report*, The Global Pursuit of Better Sleep Health.

Philips' annual global sleep survey, carried out in conjunction with World Sleep Day (March 15), surveyed over 11,000 adults in Australia, Brazil, Canada, China, France, Germany, India, Japan, the Netherlands, Singapore, South Korea, and the US to capture attitudes, perceptions, and behaviours around sleep.

Results showed that while awareness of sleep’s impact on overall health is on the rise, achieving good sleep health remains elusive. Besides being one of the top two nations having insufficient sleep, 70% of Singaporeans describe their sleep as ‘somewhat’ or ‘not at all’ well, and four in 10 (39%) say that their sleep has worsened in the past five years. The impact of this is demonstrated daily, with as many as 65% of Singaporeans saying they have experienced several episodes of daytime sleepiness throughout the week.

Stress was the main reason keeping Singaporeans up at night, with 61% of them losing sleep over worry or stress – higher than the 12-country average of 54%. Additionally, other factors that keep Singaporeans up at night include their sleeping environment (35%), distraction from entertainment such as television, social media (30%) and their partner’s snoring (14%) or sleep schedule (10%).

Eight in 10 (81%) respondents from Singapore say that they want to improve their quality of sleep. They are experimenting with a variety of methods, including instituting a set bedtime/wake-up schedule (28%), reducing their caffeine consumption (25%), playing soothing music (19%), and even sleeping in a different location from their partner (12%). Additionally, 11% of Singaporeans have also used connected care devices to track their sleeping habits, according to Philips’ Future Health Index (FHI) study**.

“It’s worrying that Singaporeans are still ranked among the world’s poorest sleepers, despite public awareness around the importance of quality sleep for overall health,” said Ivy Lai, Country Manager, Philips Singapore.

“Philips is deeply rooted in its commitment to developing clinically-proven solutions that help people take control of their sleep health. Philips aims to provide solutions that meet the growing and evolving needs of consumers and healthcare professionals alike. To bridge the current gap in diagnosis and treatment of sleep disorders, last year we launched Southeast Asia’s first Sleep and Respiratory Education Center in Singapore to upskill healthcare professionals across the region, aimed at enabling better access to sleep and respiratory care.”

In seeking a better sleep, 43% say they would be willing to use online search engines to learn more about sleep and/or treatments to improve their sleep, 41% would be open to seeing a sleep specialist. Yet, 80% of Singaporeans have not sought help from a medical professional, mainly due to the perceived high costs of sleep consultation (48%) and treatment (43%).

“Sleep is a key pillar of good overall health, as equally important as having a healthy diet and getting regular exercise. While most are aware that sleep is fundamentally important, achieving the recommended eight hours of quality sleep is still an elusive goal for many people each night,” said Dr Mark Aloia, (PhD), Global Lead for Behavior Change, Sleep & Respiratory Care at Philips.

“The lack of quality sleep may not only induce low productivity and daytime sleepiness, but also pose serious health issues if not addressed. Those who suffer from prolonged poor sleep should consult their doctor to identify contributing factors and determine if they or their partner are at risk of underlying health issues such as obstructive sleep apnea.”

Obstructive sleep apnea (OSA) is characterised by repeated interruptions in breathing throughout the sleep cycle and prevents oxygen from reaching the lungs***. As many as one in three Singaporeans suffer from sleep apnea, and 91% have not been diagnosed****.

Symptoms of OSA include choking or gasping for air during sleep, loud and persistent snoring and excessive daytime fatigue and poor concentration during the day. If left untreated, sleep apnea can have serious short and long-term health risks including heart disease, type 2 diabetes, stroke and high blood pressure.

*This survey was conducted online by KJT Group on behalf of Philips from January 9–28, 2019 among 11,006 adults ages 18 and older in 12 countries (Australia: n=750; Brazil: n=1,001; Canada: n=750: China, n=1,001: France: n=1,000; Germany: n=1,003; India: n=1,000; Japan: n=1,000; Netherlands: n=750; Singapore: n=750; South Korea: n=1,000 and the US: n=1,000). The survey was web-based and self-administered in the primary language(s) of each country. These were non-probability samples and thus a margin of error cannot be accurately estimated.
