| 0:00.0 | Well, hello, hello guys. You're listening to Beauty Bites with Dr. K's Secrets of a Plastic |
| 0:19.5 | Surgeon. And today's podcast is going to be so |
| 0:21.9 | interesting we have Zaid Dahaj. He is a citizen scientist. He's a champion of photo |
| 0:28.4 | biomodulation and that is saying that sunlight is actually good for you and maybe we're too |
| 0:34.7 | indoctrinated in the sunscreen. Sun is bad culture. |
| 0:38.4 | So I'm so curious. |
| 0:39.5 | I've been reading your posts and also your newsletter and just I love, he has a lot of scientific, |

| 1:25.3 | And I think the most important thing on my end is to try to |
| 1:28.3 | educate myself and other people through this work. And so a quick breakdown of circadian biology |
| 1:34.7 | is we're essentially just talking about the 24-hour cycle that your body follows in relation to the |
