Sunscreen for Swimmers: What to Know Before You Buy

Swimming is a great way to enjoy the summer season, but it’s important to protect your skin from the harmful effects of the sun while you’re in the water. Sunscreen is a great way to protect your skin from sun damage, but not all sunscreens are created equal. In this article, we’ll take a closer look at what you should know before you buy sunscreen for swimming.

Why Do Swimmers Need Special Sunscreen?

When you’re swimming, you’re exposed to the sun’s harmful UV rays for extended periods of time. This means that you need a sunscreen that is both water-resistant and provides broad-spectrum protection against both UVA and UVB rays. Ordinary sunscreens may wash off in the water or may not provide enough protection for extended periods of swimming.

What SPF Should You Look For?

The SPF (Sun Protection Factor) of a sunscreen indicates the level of protection it provides against UVB rays. According to the American Academy of Dermatology, it is recommended that you use a sunscreen with an SPF of at least 30. However, it’s important to remember that SPF only measures protection against UVB rays, and not UVA rays, which can also cause damage to the skin. Look for a broad-spectrum sunscreen that provides protection against both UVA and UVB rays.

What Does “Water-Resistant” Mean?

Sunscreens that are labeled as “water-resistant” have been tested and shown to maintain their SPF level after 40-80 minutes of water exposure. However, it’s important to note that no sunscreen is completely waterproof or sweatproof, so it’s important to reapply sunscreen every two hours or immediately after swimming, toweling off, or heavy sweating.

Is Spray Sunscreen Okay for Swimmers?

Spray sunscreens have become popular in recent years because they are easy to apply. However, when it comes to swimming, it’s best to avoid spray sunscreens. Spray sunscreens may not provide an even coverage and may not adhere well to wet skin, which can leave areas of the skin unprotected. Additionally, the fine mist from spray sunscreen can make the pool or other water surfaces slippery, increasing the risk of accidents.

What About Mineral Sunscreens?

Mineral sunscreens use physical filters containing minerals such as zinc oxide or titanium dioxide to reflect UV rays away from the skin. These sunscreens are generally considered safe and effective for swimming, but they may be less water-resistant than chemical sunscreens and may require more frequent reapplication. Additionally, they may leave a white cast on the skin that can be noticeable, particularly on darker skin tones.

How Much Sunscreen Should You Apply?

Experts recommend applying one ounce (a shot glass full) of sunscreen at least 15 minutes before sun exposure. For swimming, it’s important to apply sunscreen to all exposed skin, including hard-to-reach places such as the back. Don’t forget to reapply sunscreen every two hours or immediately after swimming, toweling off, or heavy sweating.

How to Choose the Right Sunscreen for You?

The right sunscreen for you will depend on a variety of factors, including your skin type, sensitivity, and activity level. Consult with your dermatologist or healthcare provider to determine the best sunscreen for your individual needs. Consider a water-resistant, broad-spectrum sunscreen with an SPF of at least 30 for swimming.

How Often Should You Apply Sunscreen While Swimming?

When swimming, it’s important not to rely on a single application of sunscreen. Even water-resistant formulas break down with prolonged exposure in the water, so reapplication is key. Reapply at least every two hours, or after swimming or sweating heavily, to maintain your skin’s protection. For proper protection, you can’t rely on waterproof or sweat-proof screen. Waterproof sunscreens are myth and misleading, no sunscreen is invincible.

How Long Does Sunscreen Last for Swimmers?

Long-term exposure to water can make sunscreen less effective, requiring more frequent applications to stay protected properly. Even if it is water-resistant, sunscreens will eventually wear off after a certain amount of time spent in the water, so it’s important to reapply every 80 minutes at a minimum. Sweating and toweling off can also cause sunscreen to wear off faster, so be sure to reapply after being active or drying off.

What If You Have Sensitive Skin?

If you have sensitive skin, consult with your dermatologist or healthcare provider to find a sunscreen that is gentle on your skin. Look for sunscreens that are labeled “hypoallergenic” or “fragrance-free” to minimize the risk of skin irritation or allergic reactions. Additionally, you may want to do a patch test before using a new sunscreen to test for any adverse reactions. Always avoid sunscreens that contain oxybenzone and other harmful chemicals, especially for infants and young children.

Conclusion

Sunscreen is an essential part of any swimmer’s skin care routine. When choosing a sunscreen for swimming, look for a water-resistant, broad-spectrum sunscreen with an SPF of at least 30. Remember to apply enough sunscreen to all exposed skin, and to reapply every two hours or immediately after swimming, toweling off, or heavy sweating. Consult with your healthcare provider if you have any questions or concerns about choosing a sunscreen that is right for your individual needs.
