The Most Important Rule of Diving: Never Hold Your Breath

As every good beginner diving student knows, never hold your breath is the most important rule of diving. Holding your breath underwater can lead to serious injury and even death. This is due to Boyle's law, which states that the air in a diver's lungs expands during ascent and contracts during descent. It is essential to maintain good buoyancy control underwater, as this will help you to stay safe and enjoy the experience of diving. If you are concerned about your buoyancy control, we recommend reading our article Tips for Better Buoyancy Control.

This will help you to understand the basic concepts of buoyancy theory and learn techniques to improve it. Scuba diving is an incredible experience, as it allows you to do something that is technically impossible: breathe underwater. It is essential that you never hold your breath, but instead breathe normally at all times while diving. Holding your breath can cause an atmospheric embolism, which is a serious and potentially fatal injury. This rule is closely related to the first rule of diving: go slow.

This will prevent your lungs from expanding too much, and also reduce the risk of decompression sickness, which is caused by the body's excessive absorption of nitrogen. To reduce this risk, divers should make a safety stop at a depth of between 3 and 6 meters. This will allow time for excess nitrogen to escape from the body. Recreational divers should never attempt decompression dives in order to return to the surface at any time.

Making a safety stop forces them to slow down and reduce most of the risk associated with diving


The PADI Open Water Advanced Course is a two-day experience in a small group of four students. During this course, divers will have the opportunity to explore new underwater activities through five special dives, including a dive charter on Rottnest Island. Here, divers can discover the beautiful waters that surround Rottnest Island, with its multitude of fish species and underwater attractions. It is important to understand that diving is a series of skills that require a lot of practice to develop. If you have any doubts about your abilities when considering taking up diving, it is best not to dive.

Additionally, make sure that you are covered both above and below water with insurance that explicitly states that diving activities are included. When scuba diving, there are several rules that must be followed at all times in order to ensure safety. These include never holding your breath, avoiding going below 40 m (130 ft), making a safety stop at a depth of between 3 and 6 meters, and never attempting decompression dives in order to return to the surface at any time. It is also important not to leave your diving equipment piled up on the deck of the boat when you return from diving, as this can be dangerous for both yourself and others. Finally, it is essential that divers receive the right training for the conditions and depth of the place they are diving in before entering the water. When teaching the PADI open water course, there are six rules that I want my students to remember before I can certify them.
