Sun Protection & Diving: What You Need to Know

As scuba divers, we often focus on the importance of protecting ourselves underwater, but it’s equally vital to prioritize sun protection before, during, and after our dives. Sun exposure can have damaging effects on our skin, and the combination of water and reflection intensifies the risk. In this article, we’ll explore the key aspects of sun protection for divers and provide valuable tips to keep your skin safe and healthy.

Understanding the Risks:

Sun exposure poses several risks for divers. The two primary concerns are the risk of sunburn and the long-term effects of UV radiation on the skin. UV radiation can penetrate the water’s surface, causing damage to unprotected skin. Additionally, the reflection of sunlight off the water can intensify the UV exposure, increasing the risk of sunburn. Prolonged and repeated sun exposure without proper protection can lead to premature aging, skin damage, and an increased risk of skin cancer.

Pre-Dive Sun Protection:

Apply Sunscreen:
Before heading out for your dive, it’s essential to apply a broad-spectrum sunscreen with a high SPF (Sun Protection Factor) of 30 or higher. Choose a water-resistant sunscreen that will offer protection even while you’re underwater. Apply it liberally to all exposed areas of your skin, including your face, neck, ears, arms, and legs. Don’t forget commonly overlooked areas like the back of your neck and tops of your feet.

Timing is Key:
Try to plan your dives for early morning or late afternoon when the sun’s intensity is lower. The strongest sun rays are typically between 10 a.m. and 4 p.m. By diving during off-peak sun hours, you can reduce your exposure and minimize the risk of sunburn.

Wear Protective Clothing:
Consider wearing a rash guard or dive skin with built-in UV protection. These garments provide an extra layer of protection against harmful UV rays. Opt for long-sleeved shirts and long pants to cover as much skin as possible. Additionally, choose lightweight and breathable fabrics that won’t retain heat, keeping you comfortable during your dives.

During-Dive Sun Protection:

Seek Shade:
When you’re on the dive boat or at the surface between dives, seek shade whenever possible. Use the boat’s canopy or umbrellas to shield yourself from direct sunlight. Staying in the shade during surface intervals reduces your exposure to harmful UV rays and helps prevent sunburn.

Protect Your Face:
Use a wide-brimmed hat, cap, or visor to protect your face, neck, and eyes from direct sunlight. These accessories provide shade and help reduce the risk of sunburn on these sensitive areas. Additionally, consider wearing UV-blocking sunglasses to protect your eyes from the sun’s glare both on the surface and underwater.

Post-Dive Sun Protection:

Reapply Sunscreen:
After your dive, it’s crucial to reapply sunscreen, especially if you’ll be spending more time in the sun. Even water-resistant sunscreens can wear off during a dive, so reapplication is necessary to maintain protection. Follow the instructions on the sunscreen packaging for recommended reapplication intervals.

Moisturize and Soothe:
Saltwater and exposure to the sun can leave your skin feeling dry and irritated. After diving, moisturize your skin with a soothing lotion or after-sun gel to replenish moisture and soothe any potential sunburn or skin irritation. Look for products that contain aloe vera or other natural ingredients known for their calming properties.

General Sun Protection Tips:

Stay Hydrated:
Proper hydration is essential for overall health and helps maintain healthy skin. Drink plenty of water before, during, and after your dives to stay hydrated and support your skin’s natural resilience to UV radiation.

Check UV Index:
Before heading out for a dive, check the UV index for your location. The UV index indicates the intensity of UV radiation and helps you gauge the level of sun protection required. Plan your dive accordingly and adjust your sun protection measures based on the UV index.

Stay Hydrated:
Proper hydration is crucial for maintaining healthy skin and overall well-being. Drink plenty of water before, during, and after your dives to stay hydrated and help your skin stay moisturized. Hydrated skin is more resistant to sun damage and recovers better from exposure.

Monitor Your Skin:
Regularly examine your skin for any changes, such as new moles, growths, or discoloration. If you notice any suspicious or concerning marks, consult a dermatologist for a professional evaluation. Early detection of skin issues can be crucial in preventing further damage or addressing any potential concerns.

Educate and Encourage:

Spread awareness among your dive buddies and fellow divers about the importance of sun protection. Share knowledge and tips to help everyone prioritize sun safety during dives. Encourage the use of sunscreen, protective clothing, and seeking shade to minimize the risk of sunburn and skin damage.

Remember, sun protection is not just for sunny days or tropical destinations. UV radiation can still be harmful on cloudy or overcast days. It’s important to make sun protection a consistent part of your diving routine, regardless of the weather conditions.

By following these guidelines and integrating sun protection practices into your diving routine, you can safeguard your skin from the harmful effects of sun exposure. Remember that sun protection is not just about short-term comfort but also about long-term skin health. Prioritize your skin’s well-being and enjoy safe and memorable dives for years to come.
