Sunshine boosts our energy levels, lifts our mood and helps us perform at our best. So when we travel between timezones, days and seasons, we just don't get enough. The HumanCharger device sends UV-free, blue-enriched white light to where we need it most, so we remain forever in sync.

Our story

Living beings are designed to rise and fall with the sun. But we extend our days, live through our nights and gallivant across the globe. Our natural body clocks are at odds with modern routines. As a result, energy levels dim, moods flatten, and our minds have to fight through a fog.

Scientist and engineer Juuso Nissila and Antti Aunio launched Valkee in 2007, to fight through the long, dark winters of their home in northern Finland. Inspired by our brain as the central ‘mood’ system and our body as the timekeeper, Valkee – the world’s first bright light headset – brings light to the parts of ourselves that need it most. So together we can exist as complete living beings – happy, focused and inspired by another day, no matter the weather or time zone.
