Doesn't my regular summer clothing protect
me against the sun?
New research from the Morehouse School of Medicine in Atlanta, GA, suggests that the most popular summer garb - shirts and polo shirts - may not adequately protect against UV rays.
A number of factors affect the level of ultraviolet protection provided by any fabric:
- Weave - tighter is better
- Color - darker is better
- Weight (also called mass or cover factor) - heavier is better
- Stretch - less is better
- Wetness - dry is better
The warmer and sunnier it gets, the more we tend to wear light colored garments, which actually let through a surprising amount of UV rays.
The difference in certified UPF clothing is the use of titanium dioxide (a sun blocker also found in sunscreen) or an UV-Absorber. Certified UV-Protective clothing is a smart preven-tative to skin cancer and helps slow down the aging of the skin.
