This book was written to give a clear, science-based understanding of tanning and sun exposure, separating myth from measurable fact, so that you can enjoy sunshine intentionally, responsibly, and without becoming a dermatology slideshow.
There’s some lighthearted tone, friendly science talk, and occasional humor to keep things lively, but the science is legit. If any joke hits a nerve, please know none was meant to offend.
Proudly sponsored by Sola: UV Index and Sun Exposure, the sun-savvy iOS app that makes sun exposure management feel effortless.
Disclaimer
The human researched, checked, and re-checked the science but GenAI helped polish the wording and create illustrations (shoutout to ChatGPT and Nano Banana). There’s art for nearly every section, in case flipping through pictures is more your style.
