Normal clothing provides varying levels of sun protection, and it's important to understand that not all fabrics are created equal in this regard.
Sun Protection Factors of Common Clothing
| Clothing Item | Approximate SPF | Notes |
|---|---|---|
| Standard White Cotton T-Shirt | SPF 5 | Provides minimal protection. |
Factors Affecting Clothing SPF
The level of sun protection offered by clothing is influenced by several factors:
- Fabric Type: Densely woven fabrics generally offer better protection than loosely woven ones.
- Color: Darker colors absorb more UV radiation than lighter ones, providing better protection.
- Thickness: Thicker fabrics provide more protection than thinner ones.
- Wetness: Wet clothing offers less protection compared to dry clothing.
- Stretch: Stretched fabrics can become more porous, reducing their SPF.
Practical Insights
- Layering: Wearing multiple layers of clothing can significantly increase your overall sun protection.
- Specific Sun Protective Clothing: Consider purchasing clothing specifically designed for sun protection, which often has a much higher SPF rating (UPF).
- Sunscreen: Always apply sunscreen to exposed skin, even when wearing clothing. Remember, a standard white cotton t-shirt is equivalent to only an SPF 5 sunscreen, according to the reference.
Conclusion
While clothing offers some level of sun protection, it's not a foolproof method. Using a combination of protective clothing, sunscreen, and avoiding peak sun hours is essential for safeguarding your skin.
