Sun Care on Dive Trips: A Prudent Approach for Divers

Diving inherently exposes us to environments where UV radiation is abundant. On the surface, reflections off the water amplify solar intensity, while at depth, though UV penetration diminishes, prolonged surface intervals, boat travel, and pre/post-dive activities still present significant exposure risks. Cumulative exposure can lead to acute sunburn and, over time, increase risks of more serious dermatological issues.

Leading medical organisations and dive safety agencies consistently highlight the importance of proactive sun protection. Protecting your skin is not merely a cosmetic concern; it is a critical component of overall diver health and safety, preventing discomfort that could impair your diving experience or, in severe cases, necessitate medical attention.

Effective sun care involves a multi-faceted approach. Begin by seeking shade whenever possible, especially during peak UV hours (typically 10 AM to 4 PM). Wearing sun-protective clothing, such as rash guards, long-sleeved shirts, wide-brimmed hats, and sunglasses, offers a physical barrier against harmful rays. Many modern dive skins and suits also incorporate UV protection, a feature worth considering when selecting gear.

When applying sunscreen, opt for broad-spectrum products with an SPF of 30 or higher. Crucially, choose 'reef-safe' formulations to protect delicate marine ecosystems. These products typically avoid oxybenzone and octinoxate. Apply generously at least 15-30 minutes before sun exposure and reapply frequently, especially after towelling off, sweating, or spending time in the water, even if the product claims to be water-resistant. Manufacturers' instructions regarding application and reapplication intervals should always be followed diligently.

Maintaining proper hydration is vital, as sun exposure and physical activity can accelerate dehydration. Drink plenty of fresh water throughout your dive trip. Dehydration can exacerbate the effects of sun exposure and contribute to fatigue, potentially affecting your performance and enjoyment of dives.

After sun exposure, particularly if you've experienced any redness or mild sunburn, gentle after-sun care is recommended. Use moisturisers containing aloe vera or other soothing ingredients to rehydrate the skin. If sunburn is severe, blistering, or accompanied by symptoms like fever or chills, seek medical attention promptly. Consult your doctor or a medical professional if you have any concerns about sun exposure or skin changes.
