How does the Valkee Humancharger work?

The Valkee Humancharger is a quick, effective, and convenient way to get your daily dose of light during the dark autumn and winter months – even on the go. This practical device hangs around your neck, leaving your hands free and allowing you complete mobility.

The Humancharger (Valkee 4) directs bright light into the light-sensitive regions of the brain. This convenient device only needs to be used for 12 minutes a day to mimic a sufficient dose of sunlight.
