Building the Evidence Outside the Lab by Morgan Pattison

Research in the field is uncovering lighting’s impact on human health and performance. LED lighting systems provide new opportunities for controlling the spectrum, intensity and duration of light exposure. These levels of control can be engaged as we come to better understand the effects of lighting on human health and performance. There is already good evidence that lighting can be alerting, affect melatonin secretion and affect sleep. Lab-scale studies have shown these impacts under highly controlled conditions. And these effects can have large-scale health and productivity implications. But right now, there’s still a lot we don’t know about physiological responses to light. Most research to date has been conducted in laboratories, where the conditions don’t always match what happens in the real world, so there’s a need for more studies in real-world settings where the light stimulus is realistic and the physiological responses can be collected from a sufficiently large group of participants. The U.S. Department of Energy (DOE) is working to address these needs.
