Sleeplessness in Singapore—why is it a problem?
One commenter chimed in: 'I think every country that has tech or light will have this issue.' It's a fair point. Artificial light and digital distractions are global. The struggle that's become a 'new normal'
In 2023, the Lee Kuan Yew School of Public Policy officially classified sleep deprivation in Singapore as a public health crisis — studies revealed that Singapore ranked as the third most sleep-deprived city in a survey of 43 cities worldwide. Startlingly, only one in four Singaporeans reported getting more than seven hours of sleep per night, and just 17% can sleep through the night uninterrupted.
The effects of sleep deprivation go far beyond grogginess. It has been linked to serious health problems, including heart disease, hypertension, stroke, obesity, and mental health conditions such as anxiety and depression. For a country known for its efficiency and excellence, running on empty is now quietly taking a toll on the very people who keep its systems going. See also Using Mosquitoes to Fight Dengue Fever
The reasons behind this trend are complex, layered, and increasingly cultural. One key issue is what psychologists refer to as 'revenge bedtime procrastination' — the conscious decision to stay up late in order to reclaim personal time after a long day of work. Given that Singaporeans work some of the longest hours in the developed world, it's no surprise that many feel the only control they have over their lives is in those quiet hours past midnight. But what starts as a form of freedom often ends up as a trap.
For many Singaporeans, the body remains on alert long after the laptop is shut. Corporate stress doesn't end at the work desk — it lingers into the night, disrupting rest. Many office workers report poor sleep, especially before early meetings, due to the anticipatory anxiety of having to be 'on' and 'KPI-oriented' from the moment the day begins.
For students and youth, the sleep situation is equally dire. Long school days, start times as early as 7.15 a.m., and academic pressure are made worse for many by constant digital-soothing and gaming habits. Teenagers are particularly vulnerable. Not getting enough sleep puts them at risk of weight gain, mental health issues, substance abuse, and poor academic performance. A Duke-NUS study even showed that early morning classes were linked to lower grades and reduced attendance among undergraduates. What can you do?
One commonly overlooked contributor to poor sleep is lighting. Most homes use cool white light, which mimics daylight and keeps the brain in a state of alertness. What many people don't realise is that this lighting, while useful for work or productivity, actively works against the body's natural sleep rhythm when used at night. '
Switching to warm lighting in the evening — or setting up lights to gradually dim — can help the body wind down, signalling that it's time to sleep. Even the screens on our devices, while dimming automatically at night, continue to emit artificial light that delays hormonal melatonin production, which is essential for sleep.
Sleep may feel like a personal matter, but it has become a societal one. Across all age groups — from students to PMETs to retirees — Singaporeans are quietly suffering from the same issue, each in their own way.
If we are to truly value well-being as much as we value efficiency, sleep can no longer be treated as optional or negotiable. Healthier lighting, more humane work hours, rethinking school schedules, and stronger boundaries between work and rest are becoming common conversations.

Singapore's sleeplessness is no longer a badge of honour, nor just an individual habit. It's a collective warning sign, and if we don't take it seriously, we may find ourselves burning out.

Heard of 'Japanese walking'? Here's why this fitness trend is worth trying
Going for a walk is one of the simplest workouts, but it can have powerful health impacts. Walking has been linked to improved mental and cardiovascular health, and it can be effective for managing back pain. But not all walking is equally effective. A method nicknamed 'Japanese walking' on social media – also known as interval walking training, or IWT – seems to offer greater advantages than a simple stroll, or even than walking at a moderate pace for 8,000 or more steps a day. The strategy was first introduced two decades ago in a study led by Hiroshi Nose, an exercise physiologist at Shinshu University Graduate School of Medicine in Japan. The country has one of the world's oldest populations, and Dr Nose hoped that, by applying interval-training techniques used by elite athletes to its senior community, he could improve older people's health and reduce the country's medical costs, he told The New York Times in an email. After seeing promising early results, he and his collaborator, Shizue Masuki, continued to study the method in depth. While this type of exercise isn't new, it has been a trend on TikTok this summer. Here's what the science says about the benefits of interval walking and how to get started. WHAT IS "JAPANESE WALKING"? As the name suggests, interval walking is a form of interval training, which involves alternating between bursts of intense activity and more gentle movement or rest. In this case, it's basically just alternating between fast and slow walking. But compared with more classic forms of high-intensity interval training, interval walking is more approachable for many people, especially those who haven't exercised in a while or who are recovering from injuries that make high-impact activities like running difficult, said Dr Carlin Senter, the chief of primary-care sports medicine at the University of California, San Francisco. HOW DO YOU DO IT? All you need are comfortable shoes, a safe place to walk and a timer. In the studies by Drs Nose and Masuki, subjects typically walked quickly for three minutes and then slowly for three minutes. During fast periods, the idea is to feel as if you're working somewhat hard, to the point that you would have a hard time carrying on a conversation. The movement during the slow periods should be a gentle stroll. (The researchers capped the fast intervals at three minutes, they said, because that was the point at which many older volunteers started to feel tired.) They recommend taking longer strides during the fast intervals than during the slow ones, to make the activity more challenging. They also suggest engaging your arms, bending them at the elbows and swinging them vigorously with each step, which will help you maintain proper form during longer strides. In their studies, volunteers completed at least 30 minutes of interval walking four times a week. If you try it, those 30 minutes don't have to be continuous. The research suggests that breaking the sessions into roughly 10-minute segments three times a day can be just as effective. While conducting their research, they found that, by taking regular recovery breaks, many interval walkers spent more time exercising at a high intensity than they would have if they had walked continuously at that intensity, since they tired out sooner when they didn't have breaks. WHAT ARE THE HEALTH BENEFITS? In their original study of older adults, which was small, Drs Nose and Masuki found that interval walkers saw significantly greater improvements in blood pressure, cardiovascular health and leg strength compared with volunteers who walked at a continuous, moderate pace. In the decade since, a growing body of evidence from Drs Nose and Masuki and other researchers has reinforced these findings and has suggested the method may have even more benefits. A 2018 study found that, over a 10-year period, interval walking was linked to fewer age-related declines in aerobic capacity and muscle power. What's the best way to add interval walking to your exercise routine? If you haven't been active in a while, 'start low, go slow,' Dr Senter said. If three minutes feels too long for the faster intervals, start with a minute and work your way up. Over time, as your fitness improves, you will probably be able to push yourself harder during the fast bouts. Finally, if interval walking is your main form of exercise, aim to complement it with at least two days a week of strength training, along with balance and mobility training, Dr Senter said.

With a dream and a dictionary, this nurse left everything behind to start a new life in Singapore
In the depths of Ms Miao Lan's mind, the island of Singapore – some five thousand kilometres south from her birthplace of Henan, China – had always been somewhat of a promised land. The city-state is extremely small compared to the colossal "Middle Kingdom", but her father made sure to point it out every once in a while on the world map that was mounted in her bedroom. "You were both born in August 1965," he would say. "It's a small country but it's a great one." It might have been the littlest connection, but it was all that was needed for the young girl to develop a profound desire to one day step foot on Singapore soil. "(August 1965) is a coincidence but it was a connection with me ... It became one of my dreams since then, (that) maybe in the future, I would search for a better life in Singapore," Ms Miao said. In 2006, at the age of 41, she finally did, to "step out of my comfort zone". She was offered the chance by a recruitment agency – first to study and obtain a nursing board license, then to work as a staff nurse in a community hospital. It was the opportunity of a lifetime for the senior staff nurse who spent more than a decade working for a hospital in Zhengzhou. Nurses in China seldom leave the first establishment that employs them, she said. It was now or never for the woman who dreamt of living and working in the Little Red Dot. Last month, at the modest three-bedroom flat in Clementi where she lives alone, Ms Miao told me that it was one of the hardest decisions she has had to make. "I left everything behind me – my home, my stable job, my family. It was not easy," the 60-year-old said. Her husband – also born in August 1965 – was not able to leave his job as a dentist at the time while their daughter was still in school. "But I felt I needed to step out and challenge myself overseas. Deep down, I knew I didn't want to live the rest of my life wondering, 'What if I didn't do it this way?'" THE LANGUAGE OF THE HEART In 2010, she joined HCA Hospice as a palliative care nurse. It is Singapore's largest home hospice care organisation, which serves thousands of patients each year. Ms Miao's job entails providing specialised care for patients with terminal illnesses, managing their symptoms and providing emotional support during the last journey of their lives. However, she arrived in multiracial Singapore with little to no knowledge of how to speak English or any of the other vernacular languages, so it became quite a challenge when patients mostly understood English, Malay or Hokkien. It was a challenge she embraced, she told me. Over the course of our two-hour-long interview, she spoke slowly in English, paused often and furrowed her brow to find the right words to express herself, but I would not have minded at all if she just spoke in Mandarin. Yet she pressed on to speak in English, even when I posed questions in her mother tongue. She was determined to prove that she could be heard and understood in Singapore's lingua franca. "(There were) many things I needed to learn from my patients and my colleagues," she said of overcoming the language barrier. In her initial years here, Ms Miao's friends were limited to other nurses from China who had come to Singapore for work and she admitted that it often got lonely without the presence of her family. To fill her spare time, she often had a dictionary by her side, looking up words and practising their pronunciations. She had some help, too. "My Malay patients and teammates taught me the Malay language. The older people taught me Hokkien and Teochew," she said. She does not consider herself fluent in these languages, of course, but her working knowledge of key phrases have been invaluable in her job. "I can use some Malay to ask patients (about) their symptoms, like, 'Ada sakit?' (Are you in pain?), 'Banyak sakit?' (Is there a lot of pain?), 'Sini sakit?' (Is the pain here?)," she said. 'Sometimes, I cannot catch the words (they use), but I think when you use your heart and have compassion, the family and patients can understand what you are doing for them. Then they will trust you. "I feel that language is a connection bridge. It's a bridge to connect with the patient and their families." Ms Miao became a Singapore citizen in 2018 and through the years, she has amassed a photo album's worth of thank-you cards. At her home, I looked on as she took them out and perused the contents with a sense of nostalgia. One card from a family read: "Even though palliative care may seem a thankless job, the great compassion you have shown to patients and families will carry them a long way. Thank you for making a difference." Another woman thanked Ms Miao and the hospice in Chinese, informing them that she had donated S$7,500 in support of the centre "to continue serving society". I asked which patient left the most impression on her. Judging by her quick but pensive glance on the floor, I sensed that she knew who it was immediately. Mrs Koh was a home hospice patient in her 90s who lived alone and Ms Miao Lan used to care for her at her residence. One day in 2018, the older woman was hospitalised. "She called me to say, 'Miao Lan, can you come and see me? I know my time is quite short, I probably will be leaving tomorrow'. "I couldn't believe it because she was still able to talk to me, but I still felt that I needed to visit this patient." So she rushed to the hospital the moment her shift at the hospice ended. When she got there, all Mrs Koh asked her to do was to sit beside her and hold her hands. Few words were exchanged. "At the end of the visit, she told me, 'Thank you for coming. I'm not afraid anymore'," Ms Miao recalled. The next morning, Ms Miao received a phone text message from Mrs Koh's sister informing her that she had died. At this point, Ms Miao's voice quivered slightly during our interview: "I know some patients treat me like family … Usually, patients ask their family members to visit them, (so) if they call you, it means you are a very important person to them." EMBRACING ALL THINGS THAT MAKE ONE SINGAPOREAN This year, the management at HCA Hospice promoted Ms Miao to the position of nurse manager – a role she believed would have been "impossible" back in China due to her age. Such leadership roles are normally given to younger nurses, she explained, so she was surprised when the hospice had put its trust in her. It was a show of warmth and recognition for the work she had done for nearly two decades. It felt like the embodiment of the culture of acceptance and harmony that she had come to experience and love about the nation, and that is her favourite thing about Singapore. "People from different cultures, different races, different religions – they can work and live together side by side," she said. She recalled how heartwarming it was when her Muslim neighbours offered her homecooked food to eat during their Hari Raya Puasa celebrations. To her, being "Singaporean" transcends where one was born. "It's about showing your kindness, respecting differences and showing strength in unity. "It's being hardworking, practical … and contributing to society." It is also about a shared language, something she knew intrinsically would be key to her integration into society here. Singlish quips such as "cannot tahan" (cannot bear it) and particles such as "lah" and "lor" now come naturally to her. Then, of course, there is the food culture: growing to love curry puffs, laksa, and chilli crab – dishes she once could not fathom enjoying. On one of his visits to Singapore, when her husband expressed puzzlement at her liking for those dishes, she said to him with amusement: "People can change all the time." Ms Miao will celebrate her 60th birthday just two weeks after Singapore celebrates its 60th year of independence. And to the naturalised citizen, it feels very much like it is a joint celebration of a milestone together. Asked if she has any retirement plans, she said she was hoping that she and her husband would spend the rest of their days in Singapore eventually. Their daughter, now in her early 30s, has started her own family in Australia. For now though, Ms Miao is looking forward to becoming a better nurse and hopes that Singapore retains the modern exuberance that made it the shangri-la of her youth. "We go through the same things, experience all (sorts of) changes and challenges, but it's not too late to keep improving. I'm still growing up with Singapore."
