Work in the light: WELL certification and healthy lighting as a key to well-being and productivity
In the modern working environment, we have become accustomed to inspiring offices, ergonomic office chairs and state-of-the-art technology. But one crucial aspect often remains underexposed: the quality of lighting and its effect on our biological clock. The WELL certification system provides guidelines for putting people at the centre of the working environment, and healthy (circadian) lighting plays a key role in this. It is time to stop working in biological darkness and invest in a factor that can make a huge positive difference: natural and dynamic light.
The impact of light on mood, sleep and concentration
Our bodies function according to a biological rhythm that is largely controlled by light. The circadian rhythm regulates our sleep-wake cycle, hormone production and mood, among other things. Research shows that insufficient exposure to natural light leads to sleep disturbances, decreased concentration and poorer mood. Artificial lighting with the wrong colour temperature or intensity can exacerbate this problem.
WELL certification underlines the importance of healthy lighting by focusing on light levels, dynamics and exposure times. Implementing a lighting plan that matches our natural rhythms can significantly improve employee productivity and well-being.
From biological darkness to optimal lighting
Standard lighting in offices is of a low light level. The power of outdoor light is not approached at all. Because outside, we are in the thousands of luxen luminosity, and inside regularly at only 500, often lower. Despite the windows, we lack luminosity. This creates a workplace where employees feel tired and lifeless. The lack of dynamic light - which adapts to the time of day - keeps our biological rhythms out of balance. WELL certification therefore encourages lighting that synchronises with our natural needs, for example by offering intense bright blue light during the day and softer, warmer light in the evening.
This concept is increasingly used in innovative offices that recognise the benefits of a healthy working environment. Studies show that employees in offices with circadian lighting sleep better, experience less stress and feel more alert throughout the day. This translates directly into better performance and lower absenteeism.
The best business case: investing in people
Companies often invest in technological improvements and efficiency improvements, but sometimes forget that the biggest investment should be in people. A healthier and happier working environment leads to more engagement, fewer mistakes and higher talent retention. WELL certification helps organisations make tangible improvements that not only increase employee well-being, but also productivity and profitability.
Research shows that employees in an environment with optimised lighting are on average 12% more productive and their mood improves significantly. The payback on an investment in healthy lighting is often realised within a few years, while the positive impact on employees is permanent.
Moreover, WELL certification level Gold focuses on achieving 60 points, of which up to 10 can be earned with lighting. This is a relatively high number of points, while implementation can be done easily and without an installer. With Sparckel's dynamic lighting, which can simply be placed on work desks, earning these points is accessible and effective.
Conclusion: work in the light!
It is time to move away from outdated lighting concepts and move towards a working environment that is truly healthy. WELL certification provides guidance for this, and circadian lighting is an essential component. By investing in dynamic, people-oriented light, we not only create a pleasant workplace, but also improve concentration, mood and sleep quality. Employers who embrace this not only make a difference for their employees, but also realise the best business case: a sustainable and productive working environment in which people thrive.
Stop working in biological darkness, step into the light and see how wellbeing and performance improve exponentially
