## Will Flying after Scuba Diving Cause the Bends?
### Understanding Decompression Sickness
Decompression sickness, also known as “the bends,” is a condition that can occur when a diver ascends too quickly from a dive, causing nitrogen bubbles to form in the body’s tissues. These bubbles can block blood flow, leading to pain, neurological damage, and even death.
### The Relationship between Flying and Decompression Sickness
Flying after scuba diving can increase the risk of decompression sickness because the change in pressure at altitude can cause nitrogen bubbles to expand, increasing their potential to cause damage.
### Recommended Waiting Periods
To minimize the risk of decompression sickness, divers are advised to wait a certain amount of time before flying after diving. The recommended waiting period depends on the depth and duration of the dive.
**General Guidelines:**
* For dives shallower than 30 meters (100 feet) for less than an hour: **12 hours** waiting time
* For dives between 30-40 meters (100-130 feet) for 1-2 hours: **24 hours** waiting time
* For dives deeper than 40 meters (130 feet) for any duration, or any dive requiring a decompression stop: **48 hours** waiting time
### Additional Precautions
In addition to following the recommended waiting periods, divers should also take the following precautions:
* **Hydrate well:** Drink plenty of water before, during, and after diving to help flush nitrogen from the body.
* **Fly at a low altitude:** If possible, choose flights that travel at altitudes below 2,000 meters (6,500 feet).
* **Avoid heavy exercise:** Strenuous activity can increase the risk of nitrogen bubbles forming.
* **Consider a dive computer:** A dive computer can help you monitor your depth and ascent rate, minimizing the risk of decompression sickness.
### Exceptions
There are some exceptions to the recommended waiting periods. For example:
* **If you have a decompression injury:** You should seek medical attention immediately.
* **If you are flying to a higher altitude:** The increased pressure at the destination may require a longer waiting period.
* **If you are a commercial diver or spend a lot of time diving:** You may need to follow different decompression protocols.
### Conclusion
Flying after scuba diving can increase the risk of decompression sickness. However, by following the recommended waiting periods and taking additional precautions, divers can minimize the risk. If you have any concerns about diving and flying, consult with a diving medical professional.
