How much time should be observed between dives?

The recommended time to observe between dives is at least 30 minutes. This interval allows your body sufficient time to off-gas any nitrogen that has accumulated during the first dive. When you dive, your body absorbs nitrogen from the surrounding water; if you go for a second dive too soon, the additional nitrogen exposure may increase the risk of decompression sickness, commonly known as "the bends."

The 30-minute duration provides a safer buffer, enabling more effective nitrogen elimination from your body, which is crucial for ensuring diver safety and health. It's important to remember that individual factors, such as dive depth, duration, and physical condition, can influence how much time is required between dives, but the general guideline for recreational diving considers 30 minutes to be a sound safety practice.
