Sun-kissed or Sun-cursed?
Developing a Healthy Relationship with the Sun
Sunscreen, sunblock, SPF, UVA, UVB… we’re all too familiar with these summer-time terms and yet they perplex us all the same. Is SPF 50 really that much better than SPF 45? And how do they calculate those numbers anyways? Why does it burn when I rub it into my face, and how often should I reapply?
Yes, we want to protect our skin from excessive exposure, but it is only natural to seek the sun after a winter filled with cold and clouds. And of course, most can’t deny the desire for that sun-kissed, summertime glow.
But that’s just it: sun-kissed has become equated to cancer-kissed in the modern world. We are scared to go outside and rightfully so: study after study confirm that the sun is determined to fry us to a crisp and turn all our skin cells against us. And now there’s all this talk of sunscreens actually causing cancer and destroying coral reefs.
Interestingly, even though there are more sunscreens and media coverage than ever before, cases of malignant melanoma are rising every year, representing a 200% increase from 1975 to 2013¹. How could this be if our awareness and product access is better than ever?
Well, the answer is complex, but here are some key points:
In a nutshell, UVA and UVB represent different wavelengths. UVB is highest around solar noon (11 am- 2 pm) and is critical for Vitamin D absorption. UVA rays are much more intense, seeping deeper into your skin cells and causing more free radical damage. UVA is also present all hours of the day whereas UVB is low in morning and afternoon 6.
While supplements exist and offer some benefit, the most efficient and effective way to absorb Vitamin D is through direct sun exposure- 15-25 minutes a day, especially during the sun-rich spring and summer months around noon (remember this is when beneficial UVB is at its highest!). The more skin exposed the better! Our body stores up Vitamin D during the warm months to use all year long. This partially explains why many of us come down with the flu or other viral and bacterial infections in the late winter months; our bodies Vitamin D stores have dropped to their lowest point. The darker your skin, the more time you will need in the sun. You can always get your Vitamin D levels checked- 40 ng/ml is minimum; 50-70 ng/ml is ideal 6. As a supplement during the dark days of winter, we like Bio-emulsified Vitamin D by Biotics.
