What is the recommended waiting period after completing a single dive before flying?

• A. 12 hours
• B. 18 hours
• C. 24 hours
• D. 36 hours

Answer: (C)

The recommended waiting period after completing a single dive before flying is 24 hours. This guideline is based on the need to allow the body adequate time to eliminate any nitrogen absorbed during the dive. When divers are underwater, especially at depths, their bodies absorb nitrogen under pressure, and if they ascend too quickly or fly soon after diving, the rapid decrease in pressure can lead to decompression sickness, commonly known as "the bends." By waiting 24 hours after a dive, divers significantly reduce their risk of nitrogen bubbles forming in their bloodstream, which can occur if they fly too soon after a dive. This precaution is particularly important for those who have made multiple dives, as the risk factors can increase. Furthermore, medical professionals and diving organizations generally endorse this 24-hour waiting period as a safe approach for divers to ensure their health and safety.
