Why is it important to wear sunscreen while on duty?

Wearing sunscreen while on duty is essential because it prevents sunburn and long-term skin damage. Lifeguards spend extended periods outdoors, often in direct sunlight, which exposes them to harmful UV rays. Sunburn is not only painful but can also lead to more severe skin conditions, including skin cancer, over time. Regular use of sunscreen helps create a barrier that protects the skin, allowing lifeguards to focus on their duties without the distraction or discomfort caused by sun damage. This proactive approach to skin health is crucial in ensuring that lifeguards remain physically capable and healthy throughout their careers. Other options, while they may have some validity in different contexts, do not address the primary health concern associated with extended sun exposure that sunscreen directly mitigates.
