The Essential Guide to Sunscreen Application for Outdoor Activities During Summer

When engaging in outdoor activities during the summer, applying appropriate sunscreen is a must for effective sun protection. Most sunscreens available on the market feature an SPF (Sun Protection Factor) rating, an internationally recognized standard for UVB protection. SPF values can range from 15 to 100, indicating the multiple of time by which sunburn risk is reduced. For example, using SPF 15 sunscreen can extend the time before sunburn occurs from 10 minutes to 150 minutes. The PA rating, on the other hand, addresses UVA protection, with more plus signs signifying stronger protection.

Cooling off and soothing sunburn

For general outdoor activities, selecting a sunscreen with PA++ or higher and SPF 15 to 30 is sufficient, and there is no need to pursue excessively high protection levels. The key to effective sun protection lies in the correct application of sunscreen. It is advised to apply sunscreen at least 30 minutes before sun exposure, ensuring an even and adequately thick layer. Use at least a teaspoon-sized amount for the face and a minimum of 30 milliliters for the entire body. Reapply after sweating, swimming, or every two to three hours to maintain sun protection.

If the skin turns red or feels hot during sun exposure, it indicates sunburn. In case of sunburn symptoms, immediately stop sun exposure and stay in the shade or indoors. Cool the skin with room temperature water, such as taking a cold shower or applying a damp towel, and keep the affected area moisturized with hydrating products. If severe sunburn with blisters occurs, seek medical attention promptly, as damaged blisters can easily become infected.
