At What Level of SPF Should Sunscreen Be Used When Swimming?
Introduction: Sun protection is essential for protecting skin from harmful ultraviolet (UV) rays, especially when swimming. Sunscreen is recommended with a Sun Protection Factor (SPF) of at least 30.
Understanding SPF: SPF indicates the sunscreen's ability to block UVB rays, which cause sunburns. Higher SPF values offer greater protection. However, it's important to note that SPF does not protect against UVA rays, which cause skin aging and damage.
SPF for Swimming: When swimming, the water reflects sunlight, increasing UV exposure on the body. Therefore, it's recommended to use a sunscreen with an SPF of 50 or higher when swimming.
Broad-Spectrum Sunscreen: Sunscreens with "broad-spectrum" protection block both UVA and UVB rays. It's essential to choose a broad-spectrum sunscreen when swimming to provide comprehensive protection.
Reapplication: Sunscreen washes off in water, so reapplication is crucial. Reapply sunscreen every two hours, or sooner if you're sweating or swimming.
