re.BO.rn - Non-visual biometric response to polarized and non-polarized lights and their effect on sleep pattern

Sammanfattning: Obliged to respect the newly established regulations during COVID-19,  people worldwide had been forced for an extended period to a 24/7 stay at home. Due to the lack of movement, daylight, and fresh air, anxiety, depression, bad mood, sleep disorders, etc., could have been noticed in humans. As our comfort in a relaxing home environment grew, so did the exposure to a large amount of light in the evening. The Covid era was undoubtedly challenging as people spent most of their time indoors, but it is only an extension of a trend going on for a while. Light is necessary for life. Light exposure improves visual performance and safety, but there is an increasing concern about the potential impacts of light on health and thus the sleep pattern of a healthy human. Light exposure could irreversibly damage our eyes, affect brain function, and impact general physical health and well-being. Supporting the circadian health of users through electric lighting interventions could help improve sleep, mood, and cognitive functions. While researching how to enhance light characteristics in our favor while trying to find a way to upgrade sleep quality, I discovered polarized filters. Fullerene-coated polarized filters are a possible solution for transforming light into a more pleasant experience for humans. Following the examples of the scientists being their own "guinea pigs,” this study is based on a self-reported experiment, considering personal biometric parameters compared to vitality and sleepiness scale and lighting characteristics during different phases of this investigation. After reviewing the collected data, I conclude that my sleep quality improved after installing polarized filters.
