The Hidden Dangers of Sunscreen: Protecting Your Skin Naturally
For decades, we’ve been told that sunscreen is essential for protecting our skin from sunburn and skin cancer. But what if the very products meant to protect us are doing more harm than good? Many commercial sunscreens contain harmful chemicals, disrupt our skin’s natural microbiome, and may even interfere with the body’s ability to produce vitamin D. Additionally, frequent use of soap strips away natural oils, preventing our skin from building a protective barrier. And even our eyes need natural sunlight for optimal health.
Let’s explore why conventional sunscreen isn’t always the best choice, how excessive soap use disrupts our microbiome, and how you can safely enjoy the sun without damaging your skin’s natural defense system.
The Chemicals in Sunscreen: What You Need to Know
Most sunscreens on the market contain chemical filters such as:
• Oxybenzone – A known endocrine disruptor linked to hormone imbalances. Studies show that oxybenzone can be absorbed into the bloodstream, where it may contribute to reproductive issues and developmental problems (Schlumpf et al., 2010).
• Octinoxate – Another hormone-disrupting chemical found in breast milk and linked to thyroid disruption (Krause et al., 2012).
• Homosalate – Accumulates in the body faster than it can be broken down, leading to potential toxicity concerns (Kariagina et al., 2020).
• Avobenzone – Becomes unstable when exposed to sunlight, breaking down into harmful byproducts that can increase oxidative stress on the skin (Hanson et al., 2015).
These chemicals don’t just harm human health; they also devastate marine ecosystems. Many sunscreen ingredients are linked to coral bleaching, which is why places like Hawaii have banned certain chemical sunscreens.
The Role of Sunlight and Vitamin D Production
Our bodies are designed to absorb vitamin D from the sun. This essential nutrient plays a crucial role in:
• Bone health (regulating calcium and phosphorus levels)
• Immune function (reducing inflammation and fighting infections)
• Mood regulation (low vitamin D is linked to depression and seasonal affective disorder)
But here’s the catch—our skin needs its natural microbiome and oils intact to properly convert UVB rays into vitamin D. When we apply sunscreen, we block UVB rays, preventing vitamin D synthesis. Additionally, frequent washing with harsh soaps strips the skin of its natural oils, further disrupting this process.
A study published in the Journal of the American Osteopathic Association found that nearly 1 billion people worldwide are deficient in vitamin D, largely due to lack of sun exposure (Holick, 2017).
Why You Should Stop Overusing Soap
Modern hygiene practices have led us to believe that we must scrub our skin daily with soap to be “clean.” However, this overuse of soap disrupts our skin’s natural microbiome and protective barrier.
The Role of the Skin’s Microbiome
Our skin is home to billions of beneficial bacteria, fungi, and microorganisms that:
• Protect against harmful pathogens
• Regulate inflammation and immune responses
• Maintain moisture and natural oil production
Washing with harsh soaps too frequently strips away this microbiome, leaving the skin vulnerable to:
• Dryness and irritation
• Increased susceptibility to infections
• Reduced ability to absorb vitamin D from sunlight
What Happens When You Let Your Natural Oils Build Up?
When left undisturbed, your skin’s natural oils:
• Act as a barrier against environmental toxins
• Help retain moisture, preventing dry and cracked skin
• Support vitamin D conversion by maintaining a healthy oil balance
Instead of washing with soap daily, consider rinsing with water and only using gentle, natural soaps when necessary (like underarms and groin areas). This allows your microbiome to flourish, keeping your skin healthier and more resilient.
How Our Eyes Need the Sun, Too
Just like our skin, our eyes also need natural sunlight for optimal function.
Sunlight exposure, particularly in the morning, helps regulate our circadian rhythm, improving sleep and overall well-being. Studies show that exposing our eyes to natural light (without sunglasses or artificial filters) helps signal our body to produce melatonin at night, leading to better sleep cycles (Figueiro et al., 2017).
Furthermore, getting natural daylight exposure reduces the risk of myopia (nearsightedness) in children and adults (Jones et al., 2012). Rather than avoiding sunlight altogether, spend some time outside without sunglasses—especially in the morning or late afternoon when the sun’s rays are gentler.
How to Enjoy the Sun Safely—Without Sunscreen or Harsh Soaps
Instead of relying on chemical sunscreens or overwashing your skin, consider these natural ways to protect yourself while still allowing for vitamin D absorption:
1. Choose Safe Hours for Sun Exposure
The sun’s rays are strongest between 10 AM and 4 PM. To minimize the risk of sunburn while still getting enough vitamin D:
• Aim for morning sunlight (before 10 AM) or late afternoon sunlight (after 4 PM) for longer, safer exposure.
• Gradually increase sun exposure over time so your skin adapts naturally.
2. Wear Protective, Loose-Fitting Clothing
If you need to be outside during peak sun hours, opt for:
• Long, loose, breathable fabrics like linen or cotton, which provide protection without overheating.
• Wide-brimmed hats to shield your face and neck.
3. Support Your Skin Through Diet
Healthy skin starts from within. Certain foods can naturally boost your skin’s resistance to sun damage:
• Antioxidant-rich foods (berries, dark chocolate, green tea) help reduce oxidative stress from sun exposure (Pappas, 2017).
• Healthy fats (avocados, olive oil, omega-3s from fish) support skin hydration and repair.
• Beta-carotene-rich foods (carrots, sweet potatoes) may help improve skin’s tolerance to UV rays (Stahl et al., 2012).
4. Use Natural Sun Protection If Needed
For extended outdoor time, mineral-based sunscreens with non-nano zinc oxide are a safer alternative. Zinc oxide sits on top of the skin rather than being absorbed into the bloodstream, offering broad-spectrum protection without the toxic effects of chemical sunscreens.
Final Thoughts
Instead of fearing the sun, we should learn to respect and embrace it. Our bodies are designed to absorb sunlight, produce vitamin D, and maintain a natural skin barrier that helps protect us. By avoiding chemical sunscreens, reducing soap use, getting proper sun exposure for both skin and eyes, wearing protective clothing, and eating a nutrient-rich diet, we can enjoy the benefits of the sun safely and naturally.
