More light makes people more alert

People feel more energetic and alert when there is more light. This is not only true during the night, but also during the day, research done at the TU/e shows. Researcher Karin Smolders is presenting her thesis on light today.

Smolders had several trial subjects perform tasks in a lab with bright light and a lab with dimmed light. It is already known that people perform better at night and feel more alert when light is bright. The effect of light on people performing tasks during the day had never been shown before.

Karin Smolders is the first doctoral student of TU/e’s so-called Intelligent Lighting Institute. The programme started in 2010, the objective being to research ‘intelligent lighting’ enabled by LEDs.
