What is the primary preventive measure against decompression sickness?

Taking antihistamines before diving
Rapid ascent to the surface
Carefully controlling the rate of ascent and descent
Wearing a double-layered wetsuit

The correct answer is: Carefully controlling the rate of ascent and descent

The primary preventive measure against decompression sickness is carefully controlling the rate of ascent and descent when diving. This is because decompression sickness occurs when dissolved gases in the body form bubbles when the pressure decreases too quickly. Taking antihistamines may offer some relief from symptoms, but they do not prevent the condition from occurring. Rapid ascent to the surface can actually increase the risk of decompression sickness, as it does not give the body enough time to adjust to the changing pressure levels. While wearing a double-layered wetsuit may offer some insulation against temperature changes, it does not directly address the issue of controlling the rate of ascent and descent. Therefore, the most effective preventive measure against decompression sickness is carefully controlling the rate of ascent and descent when diving.
