The process

Inspire and engage your workforce with
a high-value, short term programme



Measure your employees' light intake with the LYS Button, a wearable sensor, and track energy levels with the LYS app.



Employees learn about their light habits and sleep-wake cycles, gaining insight into how to improve sleep and energy levels.



Identify simple behavioural changes in the working environment that boost engagement and productivity.


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.
