UV-Protective Clothing and Sunscreen: Expert Guidance on Sun Safety

UV‑protective garments are engineered with tightly woven fabrics, UV‑absorbing fibres such as polyester or polyamide, and designs that cover vulnerable skin. A UPF rating of 50+ blocks about 98 % of UV radiation, and the protection persists through washing if care instructions—gentle cycles, no fabric softener, shade‑drying—are followed. For water sports, the textiles must also retain elasticity, durability, quick‑drying and resistance to salt, chlorine and abrasion, meeting standards such as AS/NZS 4399.

Sunscreen use remains debated. While it reliably prevents sunburn, studies show mixed effects on skin‑cancer rates. Some research links high‑SPF (≥15) sunscreen to a 33 % lower melanoma risk in women aged 40‑75, yet behavioural factors—longer, more frequent sun exposure when users feel protected—confound results. Ultraviolet radiation is the principal cause of most skin cancers, accounting for roughly 80 % of melanomas diagnosed worldwide in 2022. Experts therefore recommend combined protection: sunscreen applied correctly, along with UPF clothing and physical shade.
