According to NAUI, a repetitive dive is defined as more than one dive within a period of _____.

The definition of a repetitive dive as being more than one dive within a period of 24 hours aligns with safety protocols established by NAUI (National Association of Underwater Instructors) and other diving organizations. This timeframe is significant because it accounts for the changes in nitrogen levels absorbed by the body during the first dive. After a dive, your body needs time to off-gas or eliminate the excess nitrogen absorbed, and the risk of decompression sickness can increase if you perform another dive too soon after the first dive.

Therefore, waiting 24 hours allows divers to off-gas sufficiently before conducting additional dives, minimizing the potential for nitrogen-related complications. It is essential for divers to understand the importance of monitoring dive profiles and ensuring adequate surface intervals, especially when planning multiple dives, to maintain safety throughout their diving activities.
