Working from home is less healthy than you think
Many of the ill effects seem to relate to evolutionary biology and our innate need to move
As companies struggle to find the right balance between in-person and remote work and workers fight for autonomy, the debate about returning to in-person work has largely focused on productivity. If employees are equally productive in remote settings, why ask them to return to the office? All things being equal, remote work is cheaper and more convenient than commuting.
Although productivity is important, we have not given sufficient consideration to the potential negative health effects of remote work for some people. Those who have the luxury of working from home might end up realising that remote work is disadvantageous to their mental and physical well-being.
A recent compilation of evidence-based studies investigating the mental and physical effects of remote work found mixed results. Some workers thrived in the remote environment, citing more time for healthy behaviours, including exercising and bonding with family, while others became less active, gained weight and reported feelings of isolation and depression.
Much of this seems to relate to evolutionary biology. Despite the changes happening around us, our bodies remain the same.
Human bodies have been in their current form for roughly 300,000 years. Humans need to move. Strong evidence correlates increased movement with a reduced risk of developing cardiovascular conditions such as hypertension and high cholesterol, chronic diseases such as diabetes and certain types of cancer, and mental health conditions, including depression and anxiety.
Be on the move
The more we move, the healthier we are. Moving every day does not just make us feel better; it is among the most far-reaching and effective forms of preventive medicine. Furthermore, sedentary activity is strongly linked to disease. More sitting time and less movement throughout the day can make a person less healthy. Both life expectancy (lifespan) and health profile (health span) are negatively affected by prolonged inactivity.
Despite incredible technological advances, the human body has basically required the same amount of movement for preventive health for more than 100,000 years. Unfortunately, technology and convenience often work against our health. With each technological victory, from the horse and buggy to the car, the aeroplane, the computer and now the smartphone, we move less. In today’s world, one can order meals, conduct relationships and even work while never taking a step. Studies of age-matched skeletons exhumed from before the Industrial Revolution – when people walked and moved more – show less knee arthritis than knees of today.
The past three years have rapidly accelerated this trend. Data on step counts during the pandemic has shown a decrease in non-exercise activity thermogenesis (Neat) behaviours, daily steps from everyday living. These are not steps from exercise; they are steps from walking to lunch, taking the stairs at work and walking to the subway or through the carpark. While much attention is paid to exercise as a way of staving off ageing and disease, Neat behaviours are also linked to disease prevention. Background steps add up over days, weeks and months. Although daily exercise is part of a healthy movement profile, the Neat activities are the coals that keep the metabolic fire warm.
Right now, many of us are not getting enough. If you want to prove this to yourself, find a way to measure your steps, such as using the health app on your smartphone. If you work in a hybrid environment, check your steps on the days you commute. They are likely much greater than on the days you are working from home while sitting next to your primary food source, the refrigerator.
Inactivity can translate into disease
In the United States, we spend US$4.3 trillion (S$5.8 trillion), 18 per cent of our gross domestic product (GDP), on healthcare. Despite spending almost twice as much, on average, as other high-income countries, we are consistently ranked in the second tier of life expectancy among Western nations. As a nation, we are not especially healthy. Our two most expensive conditions, cardiovascular disease and diabetes, cost more than US$500 billion per year (including healthcare spending and lost productivity) and are largely preventable with a healthy diet and regular movement. We are spending the most and moving the least. A recent survey found working from home in the US still is the norm for roughly 50 per cent of the workforce, but is less common in Europe and Asia, where 75 per cent to 80 per cent of workers are back in the office. As we move less, the associated healthcare costs will rise.
Another important consideration of remote work is mental health. Humans are social animals. Much like our biological imperative to move is our need to interact. Despite advances in technology, our brains thrive with in-person relationships. When in person, we learn to read body language, understand unstated nuances in communication and work more effectively with others. Studies have shown increased rates of depression and anxiety during remote work. Even if it is easier, there is a sense of isolation that develops when real, in-person communication is substituted with virtual interaction. EEG studies of the brain found that face-to-face interactions produced stronger and longer-lasting psychological connections than virtual ones.
This is not to say that everyone who works from home is facing a health crisis. There are many people who are thriving in the remote work world. Parents with children have more time to spend with their families; people have more time to walk their dogs and sometimes even go to exercise classes.
In my office, I have treated patients who are making the most of their increased time at home and living more active and healthier lifestyles. But I also see patients who have developed back and neck pain and become less healthy over the past few years. National trends back this up.
In some form, remote work is here to stay. Data from the past three years shows that there are both benefits and pitfalls to working from home. The best way forward might be a hybrid of in-person and remote work to ensure socialisation and daily movement. If you are working fully remote, set up specific meetings and times to exercise that will keep you accountable and plugged in. If your company calls for a return to in-person work at least part-time, recognise this as favourable for your long-term health. NYTIMES
