Learn more about LYS for work


In modern urban environments, we spend more than 90% of our time indoors. Mainly because of our indoor jobs.

54% of employees say that their work environment negatively impacts their wellbeing and studies shows that 60% of staff don’t have access to natural daylight.

Sleep disruption costs the UK economy more than £38bn each year due to lost productivity. Research shows that light intake is one of the main influencing factors on sleep.

What people are saying

An innovative idea for tackling a problem by looking at people’s consumption of light during the day, and addressing this behaviour in order to get a good night’s sleep.

— Dr Chris Tomkins, Head of Proactive Health, AXA PPP

With their innovative technology, LYS allows us not only to understand how our buildings affect people from a user experience side, but also let’s us give something back to our users: insights in how they can nudge their light-related behavior to sleep better and feel more energized.
