Sunlight: Friend or Foe?

The session titled "Sunlight: Friend or Foe?" explored the effects of sunlight on skin health and overall well-being, presented by Henry Lim and Yolanda Giliberti. They discussed the dual nature of sunlight, emphasizing both its harmful and beneficial effects. Lim reviewed the dermatological implications, highlighting how ultraviolet (UV) light causes skin damage and increases the risk of skin cancer, while newer research indicates that visible light also has significant biological effects, particularly on darker skin types. Giliberti then discussed the systemic benefits of sunlight, such as improved mood, cardiovascular health, and even potential protection against infections. She provided evidence linking sunlight exposure with reduced incidences of respiratory illnesses and depression, while noting the historical importance of sunlight in treating diseases like tuberculosis. The duo concluded with thoughts on personalized photo protection strategies that consider individual skin types and their unique responses to sun exposure. They stressed the need for balanced recommendations on sun exposure, promoting both protection against harmful effects and acknowledgment of sunlight's health benefits. Finally, they invited participants to the upcoming World Congress of Dermatology in 2027.
