Valkee promises to help mitigate with northern darkness and even jetlag. The product looks a lot like an iPod with headphones that emit light instead of music. Valkee claims that it’s not just eyes that are sensitive to light, but the whole brain. The reason why the product looks like it does is that ear channel is the simplest and the most socially acceptable way to bring the light to your brain.

Valkee concept is so new that some scientists have rejected the whole idea. But what does the common sense tell you? Why do we hate the idea of working in a room with no windows? Is that because we want an escape route in case of fire or because we want to see a climbs of sun during the day. Why is the south-west facing apartment more valuable than the one facing north-east. Why do we feel so energetic after vacationing in warm sunny places. Light seems to have a powerful impact on us.

Valkee is a classic example of a product that requires some believing. I don’t think many will wear light emitting head phones for 8 minutes a day if they don’t want to believe the benefits. And once you really believe in something it tends to happen.
