Why Is Natural Light Important in Offices

The Importance of Natural Light and Ergonomics in Office Design

Research by the British government suggests that most people spend between 80–90% of their lives indoors. With the rise of remote work, this percentage is even higher for some, contributing to issues like Seasonal Affective Disorder (SAD) during the darker winter months.

While working indoors has its benefits, it can also impact mental health and well-being. Employees who spend long hours at their desks, often staring at screens, may experience increased stress, sleep disturbances, and reduced productivity.

Taking regular breaks and stepping outside for fresh air and natural light can help alleviate stress. A short walk outdoors can make the difference between feeling overwhelmed and staying calm.

Access to natural light is a crucial element of office design and should not be overlooked when searching for a workspace. Natural light enhances employee well-being and productivity. Many office providers recognize this, often offering lower rental rates for offices without windows.

Studies show that employees working in well-lit offices with windows experience better sleep, higher physical activity levels, and reduced stress compared to those in windowless environments. If your office lacks natural light, take advantage of good weather by stepping outside for a few minutes—it can make a significant difference.

The Downside of Blue Light

While natural light is beneficial, poor lighting conditions—particularly excessive blue light exposure—can cause eye strain and stress.

Blue light, although different in sensation, is one of the most uncomfortable wavelengths for the human eye. It is a common trigger for migraines and eye fatigue. Historically, offices were lit by fluorescent bulbs, which have largely been phased out. However, screens, laptops, and smartphones have taken their place as the primary sources of blue light exposure.

If you’ve ever experienced dry, burning, or sore eyes, blurred vision, headaches, or increased sensitivity to light, excessive blue light exposure may be the culprit.

Poor lighting can lead to eye strain, headaches, and fatigue, all of which hinder work performance. On the other hand, a well-lit workspace can make an office feel more inviting and spacious, improving overall morale.

How Important Is Natural Light in an Office?

Natural light is more than just a design feature—it’s a necessity. Beyond boosting productivity and well-being, it enhances the visual appeal of a workspace, creating a bright and positive atmosphere. Features like glass partitions, skylights, and reflective surfaces can help maximize daylight, leading to happier and more energized employees.

Balancing Natural and Artificial Light

Here are a few ways to strike the right balance between natural and artificial lighting in your workspace:

  • Natural Light: Position workstations near windows to maximize daylight exposure. If your office is south-facing, consider blinds or shutters to reduce glare.
  • LED Lighting: Energy-efficient and available in various colour temperatures, LED lighting can mimic natural light cycles. Warmer tones help offset the harsh blue light emitted by screens.
  • Task Lighting: Adjustable desk lamps can provide focused illumination and reduce glare. LED strip lighting is also a great option for evenly illuminating larger spaces.
  • Ambient Lighting: A combination of overhead and indirect lighting creates a well-balanced brightness level. However, avoid excessive use of large screens and neon signs—after all, it’s an office, not a sports bar!

Does Natural Light Improve Employee Productivity?

Yes—numerous studies confirm that natural light directly impacts workplace productivity. Employees in naturally lit offices report higher alertness, improved focus, and greater job satisfaction.

A study published in the Journal of Clinical Sleep Medicine found that workers exposed to natural daylight during office hours experienced better sleep quality and improved work performance. Additionally, incorporating more natural light can reduce reliance on artificial lighting, leading to energy savings and a lower carbon footprint.

Office Lighting: If It’s Worth Doing, It’s Worth Doing Properly

Investing in quality lighting and smart features can be costly. While prices have decreased, research suggests that the average cost of an office lighting refit ranges from £7 to £14 per square foot.

In many coworking, serviced, and managed office spaces, lighting is managed by the provider. This means you don’t need to invest thousands of pounds in upgrades—simply find a building with the lighting conditions that suit you. If issues arise, it’s the landlord’s or service provider’s responsibility to resolve them.

Tips for Evaluating Office Lighting

  • Optimum Desk Placement: Position desks where they benefit from natural light without excessive glare.
  • Smart Lighting Systems: Automate lighting to adjust brightness levels throughout the day for consistency and comfort.
  • Smart Design & Adjustable Furniture: Use window films and desktop screens to filter excessive brightness. Adjustable desks and chairs also help minimize discomfort caused by harsh lighting.
  • Biophilic Design: Incorporate plants and natural materials to improve air quality, diffuse light, and create a more calming workspace.
