The 2nd rule of scuba diving is to equalise early and often while descending.
Why is Equalization Important?
Equalizing pressure in your ears and sinuses is critical for a safe and comfortable dive. Failure to do so can result in discomfort, pain, and potentially serious injuries like a ruptured eardrum. The provided reference emphasizes this point: "Never go deeper than you can comfortably equalise. It is common sense, but many divers forget this rule and take the risk to burst an ear drum."
Practical Advice for Equalizing
Here are some practical tips to help you equalize effectively during your descent:
- Start early: Begin equalizing as soon as you start your descent, even before you feel any pressure.
- Equalize frequently: Equalize every few feet, rather than waiting until you feel discomfort.
- Stop if you experience pain: If you cannot equalize, ascend slightly until you can equalize comfortably. Do not force it.
- Use proper techniques: The most common technique is the Valsalva maneuver (pinching your nose and gently blowing), but there are other techniques you can learn, such as the Frenzel maneuver.
- Stay relaxed: Tension can make it more difficult to equalize. Try to stay calm and relaxed.
- Avoid diving with a cold or congestion: Congestion can make it difficult or impossible to equalize.
By following these tips and remembering to equalize early and often, you can greatly reduce your risk of ear injuries and enjoy a safer and more comfortable scuba diving experience.
