Should divers wear protection even in warm waters?

Yes, to protect against marine life
No, protection is unnecessary
Only if they are sensitive to temperature
Only in cold murky waters

The correct answer is: Yes, to protect against marine life

Wearing protection in warm waters is essential for divers primarily to guard against potential encounters with marine life. While warm waters may seem inviting, they are often home to a variety of organisms, some of which can pose risks through bites or stings. For instance, jellyfish, sea urchins, and other potentially hazardous creatures are more prevalent in tropical regions. Protective gear, such as wetsuits or dive skins, not only provides a barrier against these organisms but also helps prevent cuts and abrasions from coral or sharp rocks, which are commonly found in many diving environments. Furthermore, sun protection is also a factor. Although it may not be the primary reason for wearing protective gear, having coverage helps prevent sunburn during long exposure on the water's surface. Additionally, it's important to consider that even in warm-water conditions, wearing appropriate protection contributes to overall safety and comfort while diving.
