Have you ever experienced difficulty sleeping or wrecked your sleeping schedule working on a late night project? As we are living in a century surrounded by—and immersed in—various technologies, the artificial lights in our environment have a direct effect on our biorhythm and health because of the way it influences circadian rhythm. The artificial light can easily disturb our sleep cycle when used around nighttime because the high frequency blue light makes us less sleepy. Through research, it is known that abnormal circadian rhythms have been associated with obesity, diabetes, depression, insomnia, sleep disorder, and bipolar disorder.

These findings led me to develop sol, a light lamp that mimics and uses different spectrums of sunlight to help re-adjust our circadian rhythm. The main color component transitions between red and blue light. Since the blue light suppresses production of melatonin (the hormone that puts us to sleep), it will be effective in the daytime. On the opposite side, red light induces melatonin production during the night.

sol not only helps users to re-adjust their circadian rhythm, but also allows them to customize their own 24-hour light setting to keep in sync with their internal clock.  Additionally, interacting with the lamp and sol’s mobile application will give the user a quick overview of their biorhythm, enable them to set alarms, and will promote a healthier lifestyle through tracking their sleep pattern and increasing sleep quality.
