It’s clear…workers need the right amount of light at the right time of the workday to avoid performance problems. The World Health Organization described many workplaces as being dim (< 500 lux). Far too many workers are living in biological darkness during the workday. Increasing light by using dynamic lighting (lux changes over time rather than remaining constant) from 500 to 750 and 500 to 1000 lux improved alertness, cognitive performance, good mood, and visual comfort.
Practical Application: If you decide as a leader to your workers work in a windowless office which is not a good idea to begin with because of the proven negative impact on health and performance, then at least give them more light especially if you care about any of the following:
- Cognitive Performance
- Good Mood
- Visual Comfort
Finally, this is not about worker motivation. This is about LIGHT and its impact on workers who simply respond as humans respond.
