Knowledge, Perceptions and Photoprotective Behaviors Against the Damaging Effects of Direct, Indirect, and Blue Light: There Are No "Cheat Days".

ABSTRACT

Objective: We sought to evaluate the impact of the coronavirus-19 (COVID-19) pandemic on sun-seeking and sun-safe behaviors. Methods: We conducted an online, cross-sectional, population-based survey. Results: In total, 1,001 respondents participated in the survey and reported being exposed to 12 or more hours of sunlight (i.e., direct and indirect ultraviolet light, and blue light) each day. Participants self-reported a net increase in all types of light exposure since the onset of the COVID-19 pandemic, especially to blue light (+38%). Notably, while the effects of direct sunlight were well known among survey respondents, they were less aware of the potential damaging impact of indirect sunlight and blue light. Limitations: As the survey was only conducted among residents of the United States, results might not be generalizable to all geographical regions. Conclusion: Social outreach strategies are required to improve sun-safe behaviors. Future behavioral interventions should encourage the implementation of broad-spectrum sun protection.
