What is the recommended waiting period before flying after scuba diving with no decompression?

The recommended waiting period before flying after scuba diving with no decompression is 12 hours. This recommendation is based on guidelines established by various aviation and diving safety organizations to minimize the risk of decompression sickness, also known as "the bends." After diving, especially with multiple dives or deeper dives, nitrogen is absorbed into the body's tissues. When ascending quickly to higher altitudes, the reduced atmospheric pressure can cause that absorbed nitrogen to form bubbles, which can lead to health issues.

The 12-hour waiting period allows time for nitrogen to safely leave the body and reduces the chances of these harmful effects. It is important for divers to adhere to these recommendations, as they are designed to ensure safety while transitioning from underwater environments to flying. While different organizations may suggest varying times for different types of dives, the 12-hour guideline specifically addresses no-decompression dives, making it the appropriate period to wait before flying.
