Sunscreen Use Indoors: Clarifying UV Exposure Risks
Khaosod Online reports on the necessity of wearing sunscreen while indoors, highlighting that UVA rays penetrating windows pose a greater risk than household appliances.
A recent report from Khaosod Online addresses the common question of whether sunscreen is necessary when staying indoors. While many people worry about UV radiation from household electronics like televisions, computers, or fluorescent lights, the report clarifies that these devices emit negligible or no UV radiation that would harm the skin.
Instead, the primary concern for indoor skin health is UVA radiation that enters through windows. Clear glass allows approximately 75% of UVA rays to pass through, while tinted or reflective glass still permits between 25% and 50% penetration. UVB rays, conversely, are largely blocked by glass.
For residents and travelers spending significant time near windows, this information is relevant for maintaining skin health. Experts suggest that if one wishes to protect their skin from the UVA rays filtering through glass, applying sunscreen with appropriate SPF and PA ratings remains a recommended practice. While the report provides guidance on UV penetration, it does not establish specific medical requirements for individuals. The necessity of sunscreen use remains a personal choice based on one's proximity to windows and exposure to natural light throughout the day.
