What does the Center of Disease Control recommend regarding sunscreen?

The recommendation from the Centers for Disease Control and Prevention (CDC) emphasizes the importance of using broad-spectrum sunscreen with an SPF (Sun Protection Factor) of 15 or higher. This is because broad-spectrum sunscreens provide protection against both ultraviolet A (UVA) and ultraviolet B (UVB) rays, which are responsible for skin damage and increase the risk of skin cancer. An SPF of 15 or higher offers a more effective barrier against the harmful effects of sun exposure, helping to prevent sunburn and long-term skin damage.

The other options do not align with CDC guidelines. Using any sunscreen, regardless of SPF, does not ensure adequate protection, particularly because some products with lower SPF may not effectively shield the skin from significant UV exposure. Avoiding sunscreen altogether contradicts safety practices aimed at preventing skin cancer and sunburn. Applying sunscreen only once a day is insufficient because it can wear off due to sweating, swimming, and other factors, necessitating reapplication every two hours or more frequently if in direct sunlight. Thus, the recommendation for a broad-spectrum sunscreen with an appropriate SPF is critical for effective sun protection.
