Deep dives

The Role of Light in Sun Exposure Research

Research on UV light has largely been conducted in isolation, neglecting that only less than 10% of sunlight is UV. The majority of sunlight, over 50%, consists of red and infrared light, which can mitigate the harmful effects of UV on the body. This revelation raises the question of why studies do not consider the real-world context of sunlight exposure. Understanding the balance of light wavelengths is crucial, as red and infrared light can help reduce skin inflammation and DNA damage, suggesting a need for a more comprehensive approach to studying sunlight's effects on health.
