Rowan Jacobsen has built a career writing about the science most people get wrong. His new book, In Defense of Sunlight: The Surprising Science of Sun Exposure (Simon & Schuster, June 16), goes after one of the most settled pieces of public health advice of the last forty years: stay out of the sun.
We're flagging it for a reason beyond a good summer read. The science he pulls together speaks directly to the work of one of our clients, Cytokind.

What the book says
Jacobsen's case rests on research that rarely makes it into a doctor's office:
| • |
A 20-year follow-up of nearly 30,000 Swedish women found the sun-avoiders died sooner, ranking sun avoidance as a mortality risk on the same order as smoking. |
| • |
Sunlight does far more than make vitamin D. It releases nitric oxide, sets circadian rhythm, calms inflammation, and shapes immune function. |
| • |
He gives real attention to narrowband UVB, the 300 to 310 nanometer band dermatology has used for decades to treat psoriasis, with no matching rise in skin cancer. |
Why it matters for Cytokind
Cytokind brings clinically established narrowband UVB phototherapy (the Phothera device line) to patients, extending a proven, physician-prescribed therapy to other conditions driven by systemic inflammation. When the public conversation starts treating light as something that acts on the immune system, the ground Cytokind is building on gets firmer.
