8 Natural Ways to Prevent a Sunburn (And Sunscreen’s Not One of Them)

beachAs summer descends upon the world, a young Primal eater’s fancy turns to playful frolicking in the sunshine. And when you’re frolicking, the last thing you want to do is slather a bunch of horrible-smelling, greasy, overpriced sunblock all over your body. It makes you slippery and imbues your countenance with a deathly pallor that is very unbecoming. If you could, you’d love to avoid the nasty practice altogether. You’d love to use more alternative methods. Methods that may not have the support of the medical community, but for which supportive research does exist. Seeing as how a common refrain throughout the newly Primal is that sunburns seem fewer and further between than ever before, I’m guessing that there’s something to it. Dietary? Supplementary?

Seeing the Light: Why Sun Exposure May Be Good for Your Eyes

iStock 000011181239XSmallHaving immersed myself in all things Primal for so long, I find myself viewing nearly everything through the prism of human evolution. Is this food, activity, environmental stimulus, or social more an evolutionary novelty? If so, might it possibly conflict with or impede our pursuit of good health? Is it benign? An improvement, even?

Grok logic will only get you so far. It’ll give you a nudge in the right direction – that is, headed straight to honest inquiry and further research – but it’s not enough. You shouldn’t rest on your laurels if Grok logic suggests what you’re doing is right, and you shouldn’t make big changes just because Grok logic suggests you’re doing something wrong. Instead, use those insights to generate hypotheses, then try to explore them. Research, read, ask more questions. At least, that’s what I try to do. It’s awfully tempting to just go with conjecture (especially if it turns out to be right on a fairly regular basis!).

The Importance of Play, Long Walks and Outdoor Workouts, or Why the Optional Stuff Isn’t Actually Optional

optinBefore I get to today’s Monday Musings I wanted to give a shout out and big thanks to everyone that came out the inaugural PAST in Southern California this weekend. It was wonderful meeting each of you in person. And because of you the first event was a smashing success. So thank you!

Coming out of the gate, this event surpassed my expectations by a large margin. 30 devoted Primal enthusiasts trekked from all over SoCal and even as far as Phoenix to spend 7 hours immersed in all matters Primal. We convened at Karma Crossfit in Manhattan Beach thanks to our gracious hostess Katy Rickman. I was particularly impressed by the knowledge and passion from the audience about the Primal Blueprint, and how quickly they absorbed and appreciated the message. The guests added so much to the event and kept me excited and energized for 7 hours, which I must admit is about twice as long as I’ve ever talked in a single day.

Dear Mark: Seasonal Affective Disorder and Light Box Therapy

SADWith holiday fun come and gone, it’s the time of year when we all truly settle into winter. Spring is a long way off at this point. The cold and darkness aren’t going anywhere any time soon. Most people find their way through the season with a mixture of enjoyment and impatience (and maybe a warm weather vacay), but others have serious reason to dread it each year. Few of us, I think, like giving up our extra hours of daylight. The relative darkness of winter, however, presents a particularly harsh challenge to those who battle SAD – Seasonal Affective Disorder – a form of depression associated with fall and winter’s more limited sunlight.

Dear Mark,

I’m curious if you’ve done any research into the viability of full spectrum light lamps in combating SAD. I can’t get outside much during the limited daylight hours this winter and I’m noticing a marked dive in my mood – I was diagnosed as clinically depressed in college and while I’ve been able to combat it mostly through living Primally, I’m finding it especially difficult this winter (again, probably due to the fact that I really can’t go out during the day right now.) So have you done any research or know of any studies stating how harmful or beneficial these lights are, especially regarding UV rays? Thank you!

Katie

Monday Musings: Vitamin D, Toxic Strawberries, New PUFAs Coming Soon

sunA quick look at Google Trends shows a clear, undeniable trend: that of regular folks armed with curiosity, questions, and Internet connections taking their health into their own hands and searching for information on “vitamin D.” Search traffic for the keywords is at an all-time high, having steadily increased for years. But just as people are discovering importance of getting enough vitamin D, either through sunshine or supplementation, out comes the official paltry new vitamin D guidelines.

As far as I’m concerned, vitamin D deficiency is one the biggest health issues in this country. I’ve written extensively on the topic here, here, here and here. I’ll continue to get sunlight when it’s available and supplement when it’s not. And I’m sure my fellow paleo bloggers will do the same. (As mentioned yesterday, Dr. Davis does a good job explaining exactly how paltry the new recommendations are.) This is a perfect example of why we distance ourselves from CW. What do you say? Has the latest report changed how you view vitamin D?
