Backpacker Radio Skin Protection on Trail: Sunscreen, Clothing, and Supplements with Dr. Katie Manno
In today’s episode of Backpacker Radio presented by The Trek, we are joined by dermatologist, and my old pal, Dr. Katie Manno. This is a chat I’ve been wanting to highlight on this podcast for years now, and it lived up to my lofty expectations. Dr. Manno gives us a thorough runthrough on all things skin health related and how it pertains to extended time in the outdoors, including why sun protection is so important, the difference between chemical and mineral sunscreens and which is better for the trail, how much and what SPF sunscreen hikers should use, the safety profile of chemical sunscreens and what chemicals specifically to avoid, sun protective clothing and the science behind UPF ratings, vitamin D considerations when using sunscreen and/or sun clothing, what supplements and skin care products she recommends to optimize skin health, and much more. Needless to say, you will come away from this chat smarter than you entered it.
We wrap the show with why one former guest always uses a bear canister when thru-hiking, we opine on whether donating hair can land you in the slammer, I give an update on my 175-mile lap around Denver, and the triple crown of dog breeds.
