Interactive Therapy Light Combining Real and Artificial Daylight

Currently, a large portion of the population lives and works in artificial environments with limited access to sunlight, leading to the experience of symptoms similar to seasonal depression. Electronic therapy lights that supplement simulated sunlight have been used to treat seasonal depression, and they can also help users maintain a healthier circadian rhythm. This study presents a working prototype utilizing a hybrid system comprising real and artificial sunlight that serves two purposes—synchronizing the user’s circadian rhythm with the natural daylight cycle, and supplementing the user’s exposure to daylight when required.
