What is a common consequence of not allowing adequate surface time after a dive?

• A. Increased risk of barracuda encounters.
• B. Decreased air consumption.
• C. Decompression sickness.
• D. Hypothermia.

Answer: (C)

Decompression sickness, also known as "the bends," occurs when a diver ascends too quickly after spending time at depth. During a dive, the body absorbs nitrogen from the air we breathe, which is then dissolved in the body's tissues. If a diver ascends without allowing sufficient surface time or performing a proper safety stop, the decompressed nitrogen can form bubbles in the bloodstream or tissues, leading to various symptoms ranging from joint pain to more serious neurological issues. Adequate surface time, which includes safety stops and gradual ascent, is essential for allowing nitrogen to be safely expelled from the body. This is critical in preventing the formation of those dangerous bubbles that lead to decompression sickness.
