Protect your skin while underwater with sunscreen and protective clothing for divers.

What should divers do to protect their skin while diving?

• A. Stay in deep water to avoid sun exposure
• B. Only dive at dusk or dawn
• C. Use sunscreen and wear protective clothing
• D. Avoid wearing any gear

Answer: (C)

Using sunscreen and wearing protective clothing is essential for divers to protect their skin while diving. Water surfaces can reflect sunlight, increasing exposure to harmful UV rays. Applying a broad-spectrum sunscreen with a high SPF helps shield the skin from sunburn and reduces the risk of skin cancer over time. Additionally, wearing protective clothing, such as wetsuits or rash guards, provides a physical barrier against both UV exposure and potential abrasions or stings from marine life. Staying in deep water may reduce direct sun exposure, but it does not eliminate the risk entirely, especially if the surface is reflective. Diving only at dusk or dawn minimizes sun exposure but may not be practical or safe for all diving activities. Avoiding gear entirely is not feasible or safe, as diving gear is crucial for safety and comfort underwater. Thus, using sunscreen and wearing protective clothing is the most effective strategy to protect oneself during dives.

Let me lay it out plainly: the skin protection you use above the water matters just as much as the gear you wear below. The sun doesn’t take a vacation when you’re in a wetsuit, and the water isn’t a perfect shield. In fact, surface reflections can crank up UV exposure, and that’s not a small thing. Skin that’s burned or irritated after a session can take days to recover and, over the years, sun damage adds up. The good news: a smart combo of sunscreen and protective clothing does the heavy lifting. Here’s how to make it work in real life.

Why the sun is a sneaky foe, even when you’re not baking on the beach

You might assume you’re safe if you stay in deeper water or keep your head under the surface, but UV rays don’t disappear just because you’re in the shade of a boat, a reef, or a wave. The surface acts like a mirror, bouncing sunlight back up and into whatever skin is exposed. UVA rays, which contribute to aging and long-term damage, can penetrate through clear water, while UVB rays—those who cause sunburn—are still a threat, especially during peak hours. And let’s be honest: the schedule of an underwater outing isn’t always at dawn or dusk. We’re talking mid-morning glare, a sun that seems friendlier than it is, and a tendency to forget that skin on the neck, ears, and backs of hands is part of the exposure too.

This is where sunscreen and protective clothing come in as a straightforward, practical shield. Think of them as your first line of defense, paired with sensible surface-time management and smart gear choices.

Sunscreen: what to look for and how to apply it

If you’ve ever stood at the edge of a float line and slathered on product, you know there’s more to it than just “slap it on.” Here’s the lean, useful version:

• Broad-spectrum coverage: Look for protection against both UVA and UVB rays. That means labels like “broad spectrum” are non-negotiable.

• SPF 30 or higher: SPF 30 is a solid baseline; SPF 50+ is a nice upgrade for long exposures or very sunny climates. The higher the SPF, the longer you can stay out of the burn zone—though reapplication every two hours remains essential.

• Water resistance: Because you’ll be splashed, swatted by spray, and possibly covered in salt, choose a sunscreen labeled water resistant (40 or 80 minutes). It won’t last forever, so plan to reapply during surface intervals or after an in-water break.

• Reef-safe formulas: If you’re sharing delicate marine ecosystems, pick mineral-based sunscreens with zinc oxide or titanium dioxide as the active ingredients. They’re gentler on coral communities and still offer solid protection. Avoid chemical filters that have raised environmental concerns in sensitive waters, and you’ll feel good about what you put on your skin and what ends up in the reef.

• Application timing: A good rule of thumb is to apply 15 to 30 minutes before you head into the water so it has time to bond with the skin. Reapply every two hours, more often if you’re sweating, toweling off, or taking long surface intervals. Pro tip: don’t rely on your skin’s memory—set a reminder if you’re in a busy trip schedule.

Simple, practical routine you can actually keep

• Do a quick clean and dry of hands and exposed skin before you apply.

• Target ears, neck, back of hands, underarms, and any exposed areas between the cuff of a sleeve and glove. You’d be surprised how easy these slip through the cracks.

• Reapply during surface intervals or after you’re wrapped up in a towel and ready to re-enter the water.

• Bring a spare bottle or a small spray version so you’re not tempted to skip reapplication just because you’re on a fast schedule.

Protective clothing: the fabric that does the heavy lifting

Sunscreen is terrific, but clothing adds a durable layer of protection that sunscreen alone can’t supply. Here are the wardrobe choices that actually make sense in a real-world setting:

• Wetsuits with UPF ratings: A 2–5 mm full wetsuit is a standard choice for many saltwater adventures. Look for UPF (Ultraviolet Protection Factor) 50+ on the fabric. It’s not just about staying warm; it’s about blocking a significant chunk of UV before it even gets a chance to land on skin.

• Rash guards and long-sleeve tops: Even if a full wetsuit isn’t on the agenda, a fast-drying rash guard (UPF 50+) is a lightweight, practical option for day trips with a lot of surface time. It covers arms and shoulders—areas that love to burn—and won’t cramp your movement on a buoy line or a gentle current.

• Protective gloves and booties: For people who tend to sunburn on the backs of the hands, gloves are more than a comfort feature. They shield tendons and knuckles during long surface waits or when you’re working near coral or rocky substrates.

• Hats and sun sleeves for surface intervals: When you’re waiting for your turn on the boat or waiting for the current to settle, a wide-brim hat and a sun sleeve can keep necks and ears from turning pink.

Sizing up your local sun and tailoring protection

Climate, season, and latitude all color the protection you’ll need. A tropical noon session in a bright, clear sea calls for more coverage than a cooler, overcast morning in temperate waters. The same goes for altitude: higher UV exposure at altitude is a real thing—though it’s less of a factor underwater, surface time in a windy, sun-baked area can feel brutal. The trick is to know your skin and respect your past burns. If you’ve got history with sun sensitivity or freckles that pop up faster than you expect, lean toward higher UPF garments and stronger sunscreen, and plan more frequent reapplications.

Surface time, reapplication, and a few practical tips

Let me explain the rhythm of protection that fits real-life sessions:

• Before you head out, sunscreen up. Slather every exposed inch, including ears, back of the neck, and the top of the feet if they’re getting sun-exposed during surface intervals. If you’re wearing booties, remember the tops of the feet and any ankle skin.

• Reapply during long surface breaks. You’ll be surprised how quickly sunscreen wears off with spray, salt, and perspiration.

• Use protective clothing during gaps in exposure. A quick top-up from a rash guard or a light hood can dramatically cut the UV load.

• Hydration helps the skin too. Water might quench your thirst but not your skin’s moisture loss. Sip regularly and choose a non-alcoholic beverage to support overall skin health.

A few extra skin-health tips you’ll actually use

• Aftercare matters. Rinse off careful, pat skin dry, and apply a light moisturizer after sessions. Salt and chlorinated water can dry skin out; a mild lotion helps keep your barrier intact.

• Check skin regularly. A burn doesn’t always show instantly. If a patch looks red, irritated, or sunburned, give it a rest from sun exposure and hydrate. If you notice unusual spots or changes, it’s worth a quick check with a clinician or a dermatologist.

• Don’t forget the lips. The lips deserve protection too. A lip balm with SPF 15 or higher is a small, essential habit to form.

• Consider pre- and post-session skincare. Gentle skin care before a long day on the water can prep your skin; after your time in the water, a quick refresh helps you recover faster.

Myth busting: what not to do

• Staying in deep water forever will magically prevent sunburn. Not true. UV rays find skin, especially when the surface reflects light back up.

• Only dawn or dusk outings protect you from UV. The windows of exposure vary with your location, weather, and season. It’s a smart choice to protect consistently.

• You can skip sun protection because you’re wearing gear. Gear helps, but it isn’t magic. Sunscreen and proper clothing work in tandem with good habits.

• Avoiding all gear isn’t a realistic safety plan. Protection is a practical mix of sunscreen, clothing, and sensible exposure management. Gear is part of the safety equation.

Your quick skin-safety checklist (one-minute version)

• Broad-spectrum sunscreen, SPF 30+, water resistant, reef-safe if possible.

• Reapply every two hours, and after water exposure or toweling off.

• UPF 50+ rash guard or full wetsuit for longer sessions.

• Hat with a wide brim for surface intervals.

• Lip balm with SPF 15+.

• Hydration and post-session skincare.

A note on the bigger picture

Skin protection isn’t just about avoiding a sunburn. It’s a long-term habit that pays off with healthier skin and more enjoyable adventures in the water. The sun’s glare, salt spray, and the sometimes rough edges of underwater environments make protection a practical, everyday part of your kit. When you combine sunscreen with protective clothing, you get a simple, effective strategy that fits into busy days and ambitious itineraries alike.

In the end, the correct answer to how to protect skin while in the water isn’t a complicated riddle. It’s a straightforward, balanced approach: use sunscreen and wear protective clothing. A little planning, the right products, and thoughtful gear choices—these are the quiet, reliable tools that help you stay out there longer, feeling secure and comfortable.

If you’re curious, there are plenty of approachable resources that break down what makes a reef-safe formula and what UPF ratings really mean in everyday terms. It’s worth a quick read, not just for your skin, but for the oceans you’re exploring. After all, a healthy you and a healthy reef go hand in hand, and that’s worth protecting with every surface interval and every splash of spray.
