Effects of working from home during Covid -19 - Physical problems, pain and posture
More people are working from home amid the COVID-19 pandemic. While avoiding the office and staying socially distant is crucial to stopping the spread of the virus, working from home can bring about other health concerns. Here are some risks to take into account – but also examples of how you can find variation at your home office desk.
In Sweden, sick leave due to physical and mental ailments has increased sharply throughout the beginning of autumn 2020 (Previa). A serious development for the work environment that does not seem to stop. New statistics from Swedish corporate health care business Previa, shows that mental illness has never been as high as it is today in Sweden's workplaces. Similar reports around the world have shown large strains for people working at home, sometimes simultaneously home schooling their children and sometimes with inadequate office equipment or working space.
Many expected that the difficult situation in the workplace and the widespread work from home would be relatively temporary. But it has now turned into a protracted state that entails increased challenges for occupational health.
There is no place like the office
A current research study, carried out in Italy, examined the impact home working had on employees. They observed the perceived job productivity and satisfaction, work-related stress, and musculoskeletal (MSK) issues. In the study, the individuals at-home workstations and its setup, was included as well as how the participants related to physical activity and sitting for long periods.
The participants in the study declared that they were less productive (39.2%) but less stressed (39.2%) and equally satisfied (51%) compared to the time of office working. Regarding the physical impact, the participants felt MSK disorders, such as low back pain (41.2%) and neck pain (23.5%). They even described the neck pain to be worsened in 50%, of the cases. The group suffering from physical conditions also reported a lower job satisfaction. The study stated that the home environment is not always an adequate place to work, with an increased risk for mental health and MSK problems.
Screen time and night time
Not only does working from home present new ergonomic problems, it can give other side effects as well. The pandemic has given us all different local prerequisites and a varied amount of freedom in our everyday life. It is easy to get stuck in front of the screen. Today we use many of our devices for other tasks than work. This has for some people resulted in sleep disorders and, sometimes, even depression.
There is a stated relation between the exposure of blue light from i.e. mobile devices and laptop screens and a disturbance in the circadian rhythm. While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours).
Break the circle – not the rhythm
So, what can we do to make the everyday home office be more ergonomic and productive? Well, try to work with the rhythm of your body, not against it.
- We must remember, that we have only been indoor creatures for a very brief period of the human history, says Henrik Clausen, director of the Fagerhult Lighting Academy. Our innate biological history is that of living outdoors, sleeping under the stargazed sky. We depend on the daylight rhythm for our inner balance. So, while you work from home - try to increase the intake of natural light during your workday. Maybe take a morning walk or a walk during your lunchbreak, or perhaps sit outside while drinking your coffee? If possible, place your work desk near a window and let the dynamics of the daylight outdoors help balance your inborn rhythm during the day. Also make sure that you have the right electrical light for your work desk, so you can see your work properly and not strain your eyes.
The key to prevent pain and posture problems, is to have variation and flexibility in your working space. The possibility to break a static circle and instead create a better flow, be it the blood flow to your head or a flow of ideas.
All in all, this new situation has been a vexing and challenging time for all of us and we hope that this unusual everyday life will soon find a more agreeable pace. Remember to be kind to yourself, and find the bright spots in your situation, where ever they might be.
Eight tips for a good workplace at home
- Sit properly - If the kitchen table is the only surface available, be sure to sit properly with a backrest. Putting a pillow in the lumbar region as extra support can be a way to help the back. If the usual chair is too low, sit on a pillow. The forearms should be able to rest on the table without the shoulders being pulled up.
- Be creative - Look around at home, are there other, less obvious places to work or vary your posture? A shelf or chest of drawers can, for example, work excellently as a standing table. Feel free to work in several different places in the home.
- Regard the light - Make sure you have good light. Perhaps you can use a floor lamp that you can move around. Be careful to avoid glare or flicker. Daylight is also a good contribution to your workplace. If possible, plan your stay-at-home-desk so you have the opportunity to look out the window sometimes.
- Avoid shoulder pain and ”vulture neck” - Find ways to place the computer at a good height for the eyes. Having the laptop in your knee is not ideal for the neck.
- Change position often - Remember not to sit statically for several hours. Do not stay in the same place when it's time for digital meetings. Get up during group meetings, or sit on the couch for a while. The most important thing is variety and changing body position often.
- Rest your eyes - If you spend a lot of time at the computer, make sure to rest your eyes sometimes. Look out the window or change direction, pause your eyes for a few minutes.
- Offer distance coffee - Add regular digital coffee breaks with a colleague or workgroup to check in on each other, and see how you all are doing.
- Make a dance break - Be sure to get up and move every hour for better blood circulation in joints and muscles. An easy way to fit in some everyday exercise in your workday, is to take a break and sit/rise from your chair 10 times – or maybe take a dance break to your favourite song? If you have a phone call planned, try to do it while going for a short walk.

Melanopic lux: lighting for education influenced by human biology
Light is essential in our daily lives, influencing our ability to see, overall well-being and performance. In educational environments, lighting quality can significantly impact students' focus, mood, and energy levels. So, how do we know what is the right amount and quality of light for this setting? Traditionally, light has been measured in lux, a unit of measurement for the intensity of light. It's used to measure how much light falls on a surface or the amount of light in a given space. One lux is the amount of light that falls on a surface that is one square meter in area when one lumen of light is spread out evenly. Recent advancements in research have unveiled the importance of melanopic lux, which goes beyond mere visibility. This measures how effectively light stimulates specific eye cells that regulate crucial non-visual functions such as sleep and alertness. In classrooms and lecture theatres, the melanopic ratio has become vital in lighting design, enabling educators to create spaces that support visual tasks and align with students' biological rhythms. In this article, we explore how lighting solutions can align with our biology, and how this helps to create optimum conditions for educational environments. The science of vision and light The human eye is a remarkable organ designed for high-resolution colour vision within a small area (approximately 2 degrees of the visual field) while relying on peripheral vision for motion detection. This dual-function system, shaped by evolution for survival, continues to influence how we perceive and interact with our surroundings. Our eyes are particularly susceptible to green and yellow light, reflecting our evolutionary adaptation to naturally lit environments. In contrast, blue light, which is chief in modern LED lighting, requires higher intensity to be perceived at the same level. Effective lighting design carefully considers brightness, timing, and distribution to support visual clarity and biological functions like mood and alertness. For example, exposure to bright light in the morning helps regulate circadian rhythms, boosting alertness and mitigating the effects of seasonal darkness. This is particularly important in educational environments, such as schools and universities, where lighting impacts mood, focus, and overall performance. Our Organic Response system provides an innovative solution tailored for these spaces. This smart lighting technology automatically optimises light levels, featuring daylight-responsive sensors and advanced occupancy detection, maintaining a balance between natural and artificial light. Doing so supports visual comfort and reduces energy consumption, making it an ideal choice for creating dynamic, efficient, and student-friendly learning environments. To further support students, well-lit spaces with minimal glare are essential for reducing eye strain and maintaining focus during extended study sessions. Adjusting light intensity and colour temperature for different tasks—such as reading, group discussions, or creative activities—enhances light's visual and non-visual effects. By integrating thoughtful lighting strategies like those offered by Organic Response, educational environments can promote healthier, more productive, and engaging learning experiences. Integrative lighting: Supporting health and well-being. Integrative lighting (also referred to as human-centred lighting) combines visual and non-visual benefits (such as emotional effects) to support biological rhythms and psychological well-being. This approach goes beyond traditional lighting solutions by considering how light impacts circadian rhythms and hormonal balance. Light exposure in the morning is critical for suppressing melatonin (the sleep hormone) and increasing cortisol (the alertness hormone). Proper timing helps align students' natural rhythms with school schedules, which often require a lot of focus. Consistent exposure to bright, cool light early in the day can enhance energy levels and cognitive performance. The melanopic ratio compares the spectral composition of a light source with daylight. Using this information, you can determine its melanopic lighting intensity. This enables the design of lighting setups that precisely meet both visual and biological lighting needs. Lighting recommendations for educational spaces Each learning environment has unique lighting needs. Libraries benefit from direct lighting on the floor, paired with ambient lighting on walls and ceilings. Vertical shelf lighting (200-300 lx) makes it easier to browse titles. Lecture halls, on the other hand, require glare-free, comfortable lighting with flexible control, ideally with pre-programmed scenarios. In auditoriums and classrooms, strong vertical lighting is crucial for clear visual communication, especially over greater distances, enhancing facial expressions and engagement. General lighting recommendations apply to all educational spaces. Our solutions meet industry standards, ensuring reading and writing areas maintain 500 lx for effective visual tasks. Using daylight-responsive sensors for luminaire rows can reduce energy consumption while maximising natural light. The number and arrangement of luminaires should be adjusted based on the room's size and function to ensure consistent illumination. The role of dynamic lighting A Double Dynamic lighting system can be a game-changer in educational environments. It allows for intensity and colour temperature adjustments to match the specific needs of activities, from quiet reading sessions to collaborative group work. Fagerhult's distinct approach to lighting means that our design is human-centric; we integrate scientific insight into light and human psychology, creating environments that support academic performance and well-being. Our focus on energy efficiency also means our advanced control systems optimise light usage while minimising energy consumption, contributing to a building’s sustainability goals. The customisable setting and flexible solutions ensure that educational environments can create tailored lighting profiles for different times of the day or specific learning activities. Long-term benefits of melanopic lighting Melanopic lighting, designed to mimic the natural light spectrum, helps regulate the circadian rhythm, which is essential for maintaining focus, energy, and emotional balance. In classrooms and study areas, proper lighting can reduce eye strain, improve sleep patterns, and enhance mood, which are critical for students' mental health and academic performance. By incorporating lighting that aligns with our biological needs, schools and universities can foster healthier, more productive learning environments,. This is particularly important during the winter months when daylight is limited. Whether through advanced tuneable white light systems, designs that maximise daylight, or energy-efficient solutions, we are dedicated to leading the way in lighting innovation for educational environments, delivering brighter futures—one classroom at a time.
The inspiration behind Nobel Week Lights: ”Light, art and technology intertwined.”
Nobel Week Lights has quickly become a beloved public celebration. During Nobel Week, Stockholm residents flock outdoors to marvel at the spectacular light installations, where contemporary lighting technology meets artistic expression. ”We aim to create a moment of gathering: around light and around something meaningful”, says Lara Szabo Greisman. Nobel Week Lights is a light festival that illuminates Stockholm during the darkest time of the year – a free cultural experience for everyone. Presented by the Nobel Prize Museum, the festival invites international and local artists, designers and students to create light artworks inspired by the Nobel Prize. The installations shed new light on the scientific discoveries, literature and peace efforts of Nobel laureates while offering a fresh perspective on the city. Fagerhult is Principal Partner of Nobel Week Lights 2024, and this year’s edition features 16 different light installations across Stockholm. The artworks can be experienced from 7–15 December, including ”The Wave”, a light installation by the art collective Vertigo, located in front of the Parliament House where visitors can walk right through the luminous wave. The Wave by Vertigo ”Light and art and creativity is incredibly intertwined because these are technologies that are constantly evolving. So part of the fun working with the artists is that they are constantly testing new technologies. And we see these incredible visual results which are based on just pure innovation”, says Lara Szabo Greisman, co-founder and producer of Nobel Week Lights. Lara Lara Szabo Greisman and Leading Lights by Les Ateliers BK The significance of light as a collective force, its ability to encapsulate life and death, joy and sorrow – indeed, the very essence of what it means to be human – makes lighting a powerful medium of artistic expression, she argues: ”The dream for the festival is that this becomes a personal experience for each and every member of the audience. A moment that they remember and cherish . A moment that they think about later and bring forward as their story of connecting with the city.”
