Summer Sun Smarts: Why Your Sunscreen Matters More Than Ever
As the weather warms up and long summer days call us outside, it’s the perfect time to revisit an important question: How can we enjoy the sun without damaging our skin? The answer starts with understanding what’s really in your sunscreen… and why it might not be protecting you the way you think.
Chemical Sunscreens: Not as Safe as You’ve Been Told
We’ve known for years that many chemical sunscreens contain ingredients like oxybenzone, avobenzone, and octinoxate—substances that are now recognized for their potential to disrupt hormones and absorb easily through the skin into the bloodstream.1,2
In fact, research published in the Journal of the American Medical Association (JAMA) and conducted by the FDA confirmed that these ingredients show up in the blood within hours of application—at levels exceeding safety thresholds.3,4
And that’s from using sunscreen exactly as directed.

We still don’t know the long-term health effects of this type of absorption—but what we do know is that these chemical ingredients are not considered safe or effective by the FDA . and the risks may be significant.5

So what can you do to protect your skin—without the chemical concerns?
The Safe Alternative: Mineral Sunscreens
The FDA currently classifies only two sunscreen ingredients as generally recognized as safe and effective (GRASE). They are zinc oxide and titanium dioxide.5
These mineral-based sunscreens absorb UV rays, preventing damage to the skin beneath.6 Zinc oxide has been found to be superior to titanium dioxide in absorbing UVA rays.7
Mineral sunscreens are a top choice for anyone looking to protect their skin without risking exposure to potentially risky chemicals—and they’re especially ideal for kids and people with sensitive skin. I recommend using a non-nano zinc oxide sunscreen.
Sun Exposure and Vitamin D
Some sun exposure is healthy—it’s how your body produces vitamin D. But burning or overexposing your skin isn’t the path to better health. Use common sense: seek shade when the sun is strongest, wear a hat and long sleeves when needed, and use mineral sunscreen on exposed skin.

Smart Sun Habits for a Healthier Summer
Sunscreen is important—but it’s only one part of a complete sun protection strategy. Here's what I recommend:
Avoid peak sun exposure: Limit your time outdoors between 10 a.m. and 4 p.m., when UV rays are strongest.
Cover up: Wear lightweight, long-sleeved clothing, a wide-brimmed hat, and UV-protective sunglasses.
Seek shade: Use umbrellas, canopies, or natural shade whenever possible.
Use mineral sunscreen: Apply generously to exposed skin and reapply every two hours or after swimming or sweating.
Nourish your skin from the inside out: Eating a diet rich in colorful fruits and vegetables—especially those high in carotenoids and polyphenols—can help reduce UV damage at the cellular level and enhance your skin’s natural defenses.
Final Thoughts: Be Smart in the Sun This Summer
You don’t need to be afraid of the sun—but you do need to be informed about how you protect yourself from it. Avoid chemical-laden sunscreens. Choose safe, mineral-based options. And if you’re ever unsure, always look to the science. Protect your skin without compromising your health. That’s the Nutritarian way.
The Bottom Line
Enjoy the outdoors—but do it safely. Skip the chemical sunscreen aisle and choose a non-nano zinc oxide formula that works with your body, not against it.
And remember, sun safety doesn’t have to mean staying inside all summer. With smart habits and the right protection, you can enjoy all the benefits of sunshine—without putting your skin at risk.
