Get the light that your mind and body need

When we don’t receive the right light at the right time of the day, our sleep, health, and productivity suffer. At Rhythm, we create physical and digital products to help people feel the psychological and physiological benefits of sunlight.

We take our light nutrition for granted

When we spend 90% of our time indoors, our body is built to survive the day. As a result, we become desensitized to living in sub-optimal, under-lit indoor environments. However, when we get the light we need, we become the best versions of ourselves. There are decades of research that have shown shown that light has a profound, positive impact on:

Cognitive performance

Reimagining light therapy

At Rhythm, we believe that everyone deserves light therapy, not just those with a seasonal affective disorder (SAD) diagnosis. We strive to reimagine light therapy so that every human has the energy they need to shine in this world.
