Can You Get Sunburned Through Regular Clothes?
Yes. You can get sunburned through clothes —especially light-colored, loose-knit ones. In this article, we’ll explain why it happens, which fabrics offer real protection and how to prevent UV damage with smarter wardrobe choices.
🌞 The Myth: “Clothes = Protection”
Do all clothes block UV rays?
No. Most everyday fabrics—like cotton, linen and rayon—offer very little UV protection. A basic white cotton tee has a UPF (Ultraviolet Protection Factor) of just 5. That means 1 in 5 UV rays still reaches your skin.
Why do clothes let sunlight through?
UV rays can pass through fabric if:
The weave is loose
The fabric is thin
It’s light in color
It’s stretched or wet
🔬 What Is UPF—and Why It Matters
What does UPF 50+ mean?
UPF (Ultraviolet Protection Factor) measures how much UV radiation fabric blocks.
UPF 5: Blocks only 20%
UPF 15–30: Moderate protection
UPF 50+: Blocks 98% of UVA and UVB rays
Is UPF clothing really better than regular clothing?
Yes. Certified UPF clothing is lab-tested and engineered to protect—unlike a cotton shirt, which offers unpredictable coverage and degrades when wet or stretched.
🧵 What to Look for in Sun-Protective Clothing
#1. Certified UPF rating
Choose garments that clearly state UPF 50+ , and ideally mention lab testing.
#2. Tightly woven or synthetic fabric
Polyamide or polyester blends naturally block more UV than cotton.
#3. Long sleeves, longer hems
More coverage = less sunscreen needed.
#4. Performance features
Look for moisture-wicking, quick-drying and breathable construction for summer comfort.
