What is the waiting period to fly after diving, due to the risk of decompression sickness?

Explanation:
After a dive, nitrogen absorbed in the body's tissues needs time to off-gas safely. Flying exposes you to lower cabin pressure, which can cause any residual dissolved nitrogen to form bubbles more easily and raise the risk of decompression sickness. Giving the body about a day (24 hours) to off-gas before flying is the standard, conservative guideline for typical recreational dives, balancing safety with practicality. Shorter waits like 6 or 12 hours don’t provide enough off-gassing time, while 48 hours is more cautious than necessary for most cases. So the recommended waiting period is 24 hours.
