How can a lifeguard minimize sun exposure while on duty?

A lifeguard can minimize sun exposure while on duty by wearing sunscreen and seeking shade. This approach effectively reduces the risk of sunburn and long-term skin damage caused by UV rays. Sunscreen acts as a barrier that absorbs or reflects these harmful sun rays, protecting the skin, and it is vital to choose a broad-spectrum sunscreen with sufficient SPF, reapplying it regularly throughout the shift. Seeking shade, whenever possible, allows lifeguards to take breaks from direct sunlight, further decreasing their overall exposure.

While avoiding water and staying indoors might seem like an option to reduce sun exposure, it is impractical for a lifeguard whose job requires them to be present at a pool or beach. Swimming at all times does not help minimize sun exposure; in fact, it could increase it due to reflection off water surfaces. Wearing heavy clothing could technically provide coverage from the sun, but it often leads to discomfort and overheating, making it an unsuitable choice for lifeguarding duties. Thus, the combination of sunscreen use and finding shade presents the most effective strategy for ensuring lifeguards can perform their responsibilities safely while minimizing sun exposure.
