If you suffer from insomnia or keep on worrying before bedtime, the Dodow Sleep Aid is for you. The sleeping robot projects a blue ring of light on the ceiling that changes size. By adjusting your breathing to the rhythm of the blue ring, the robot helps you to relax. This reduces the risk of worrying before bedtime. The sleeping robot has a diameter of 9 centimeters and works on batteries, so it fits every nightstand. You decide whether the light projection takes 8 or 20 minutes. After this time the robot switches off automatically, so that the batteries last longer.
