We spend almost a third of our lives sleeping, but getting a good night’s rest has just as much to do with the other two-thirds of it. There is a lot that we don’t yet know about sleep. What we do know is that it is extremely crucial for our physical and mental health. Having consistent, proper rest has direct effects of improved health benefits, such as lower rates of high blood pressure, obesity and diabetes. It also makes a world of difference when it comes to our mental and work performance.
When there is so much at stake, it might be alarming to know that only 44% of all Singaporeans receive less than the recommended 7 hours of sleep1. In fact, a study of 43 major cities found that Singapore is actually the third most sleep-deprived city behind Japan and Seoul2. These statistics point to a long-standing culture of extended working hours and the lack of overall work-life balance. The relationship between work and sleep is undeniably interwoven, which raises the subsequent question - how is our sleep affected now that most of us are working from home?
How working from home affects sleep
When we work from home, the usual boundaries that we have between our working lives and our personal lives begin to blur as work encroaches into the home domain. For most of us, it means that it becomes harder to separate our working and non-working hours. There are no longer any clear indicators of when it is time to end work, like colleagues leaving the office, or the daily commute. Some may even feel guilty of being less productive than usual at home, even though this may not necessarily be the case. Meanwhile, our usual escapes such as outdoor activities and social life have been rendered almost non-existent by the pandemic, leaving us not much else to do but work.
As a result, this leads to many employees working longer hours at home, and also at more irregular hours, as work has become so much more accessible. In a 2020 Bloomberg article, it was found that employees work up to 3 hours more at home, because of the reasons mentioned3. Even in Singapore, psychologists at the Institute of Mental Health noted that some Singaporeans have been putting in 50-hour work weeks since the circuit breaker started, exceeding the 48 hour cap of the Ministry of Manpower’s Employment Act4.
One of the main problems with overworking is that it causes additional, unnecessary stress to build. This keeps us up at night, affecting our sleep. In the long term, it could even cause us to develop bad sleeping habits. This is backed by a study conducted by the United Nations International Labour Organisation, which found that 42% of the surveyed telecommuters woke up repeatedly at night, as compared to 29% of normal office workers . With irregular and extended working hours having such a profound impact on our sleep, it should be unsurprising to know that the reverse is just as significant.
Relationship between sleep and work performance
Sleep is crucial to almost every other aspect of our life, but none more so than our daily activities. All of us have our work routines, social life and personal time that we get through everyday. Getting through these activities effectively requires our brain and body to be rested and fresh. Having quality sleep is essential to this, as our sleep time is when our brain and body rest and recharge, allowing us to be more energetic, focused and attentive the next day. Only with this can we be more productive, efficient and creative at work, resulting in better work performance.
Conversely, poorer sleep means that the brain and body remain tired, leading to poorer memory and focus, and thus, poor work performance. Even worse, when we work slower and less productively, it goes on to create more stress and work overloads. This further exacerbates the sleep problem and creates a vicious cycle that becomes increasingly difficult to get out of.
A lack of sleep can affect our work performance in another way, through weakening our body’s immune function. This makes us more susceptible to illnesses, resulting in absenteeism due to the greater need for recuperation. Putting ourselves out of commission for some time would similarly create a backlog of work and affect our work performance. In some cases, some employees may even adhere to presenteeism , even when ill, resulting in longer recovery times and lower work productivity due to the illness.
Relationship between sleep and overall health
In fact, when it comes to physical health, sleep is not just linked to our body’s immune function. It has many other impacts on various long-term aspects of our health as well. Getting enough good quality sleep has been medically linked to a wide range of health benefits, including the following:
Sleep is clearly essential to us leading healthy, balanced lives. With working from home being the norm nowadays, we will have to take some simple steps to adapt our lives to ensure that our sleep quality remains unaffected.
Tips to sleep better, especially when telecommuting
The circuit breaker will come to an end eventually, and most of us will be required to get back to our daily work routines. Before then, we should be mindful of how our telecommuting activities can feed into a much larger problem of improper sleeping habits. After all, it is much easier to form good habits than break out of bad ones. The following are 5 of our top tips to help with quality sleep, especially as we continue to work from home.
With so many different factors in our daily lives that have the ability to influence our sleep quality, it can be easier than we think to fall into bad sleeping habits. With telecommuting in the mix, blurring the distinctions between work and home life, the risk is even higher. The key to tackling this is to stay as disciplined and consistent as we can. With the pandemic forcing us to self-isolate at home, choosing to make intentional decisions to practice self-care and maintain a healthy lifestyle has become more crucial than ever.
