The right time，the right light

In the era of the covid-19 epidemic, working from home has become the norm. More and more people are suffering from delayed sleep-wake disorder (DSWPD). This project will modify the window system in the home environment, changing the colour temperature and intensity of light to affect melatonin production, in order to regulate the rhythm of sleep and wakefulness. By transforming the building components, the building can no longer be just a living space, but also a space where light can be used to heal the mind and body.
