True or False: Long-sleeved shirts can provide protection against the sun's rays.

Long-sleeved shirts can indeed provide effective protection against the sun's rays. The fabric of a long-sleeved shirt acts as a barrier between the skin and ultraviolet (UV) radiation. This barrier can significantly reduce the amount of UV exposure, which is important in preventing skin damage, including sunburn and long-term effects such as skin cancer.

Furthermore, the level of protection offered by a long-sleeved shirt can depend on several factors, including the type of fabric, its color, and how tightly the fibers are woven. Darker colors and tightly woven fabrics tend to offer better UV protection compared to lighter colors or loosely woven materials. Additionally, many garments are now specifically designed with UV protection in mind and may have UPF (Ultraviolet Protection Factor) ratings that indicate their effectiveness against UV rays.

Incorporating long-sleeved shirts into outdoor attire can be a practical choice for those looking to shield themselves from the harmful effects of sun exposure while enjoying activities in the sun.
