What should divers do to protect their skin while diving?

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.
