A study published in Reuters highlights research conducted by Eindhoven University of Technology in the Netherlands, which found that installing personalized and adjustable lighting in offices can help employees extend their average sleep time by 26 minutes. The study revealed that employees experienced improved sleep quality when exposed to cooler, brighter lighting with adjustable intensity and color temperature. This suggests that lighting conditions have a significant impact on our circadian rhythms and overall well-being. During the experiment, office workers were first placed in a randomly assigned lighting environment for three weeks, followed by a new experimental setup for several more weeks. The control group was exposed to standard office lighting—around 500 lux with neutral white light—while the test group used dynamic lighting systems that adjusted color temperature and brightness based on individual preferences and age. Researchers measured light exposure near the eyes and found that participants in the personalized lighting group experienced higher illumination levels in the morning and more suitable color temperatures around their workspace. This tailored approach helped align their internal clocks more effectively with natural daylight cycles. According to the findings, the personalized lighting group reported an average increase in sleep duration of 26 minutes. While this may seem small, it could have meaningful long-term effects on health, mood, and productivity. To ensure the validity of these results, the researchers plan to conduct further analysis to account for variables such as individual light sensitivity, general sleep quality, and the actual light levels recorded by optical devices. These steps will help confirm whether the observed improvements are truly due to the lighting system or other external factors. Although the current study is still in its early stages and no final conclusions have been drawn, it underscores the growing importance of personalization in workplace design. As people become more aware of how environmental factors affect their health and performance, custom solutions like adaptive lighting could become a standard feature in modern offices. Another key takeaway from the study is the diversity of individual preferences when it comes to light intensity and color temperature. The team emphasized that “personal control over lighting is clearly needed.†They also noted that even when users don’t fully understand the science behind lighting, they tend to appreciate and use the ability to customize their environment. Interestingly, only a small number of participants recognized the impact of lighting on their sensitivity, health, or productivity. However, most of them adjusted the lighting to a comfortable level when given the option. This suggests that while people may not be consciously aware of the benefits, they instinctively seek out environments that feel right for them.
