Rowan Jacobsen - In Defense of Sunlight

How much sunlight is too much? Is sunscreen necessary or harmful? What is the difference between UVA and UVB and what, exactly, is SPF? What’s the deal with red light? If you have questions about our human interactions with sunlight, join Rowan Jacobsen at The Galaxy Bookshop on Tuesday, July 14, at 7 p.m., for a talk on his new book, "In Defense of Sunlight: The Surprising Science of Sun Exposure." Jacobsen’s explorations into our relationship with the sun led him on several fascinating journeys, including a month-long stay in the Sonoran Desert, in search of answers to these and other questions.
