There are a lot of people who are interested in scuba diving. One of the reasons being the curiosity to explore the ocean. However, there are some basic rules of diving that you must know:
Breathe Continuously Like Normal
This is the most important rule of scuba diving, as any proper entry-level dive student knows. The reasoning behind that is pretty reasonable since holding one’s breath underwater can inflict major harm, if not death. The air in a diver’s lungs expands during ascent and contracts during descent, according to Boyle’s law. This is not a concern as long as the diver breaths constantly because surplus air can escape. When a diver holds his breath, however, the air cannot leave as it expands, and the alveoli that make up the lung walls eventually break, causing catastrophic organ damage. Pulmonary barotrauma is an injury to the lungs caused by over-pressurization. It can cause air bubbles to leak into the chest cavity and bloodstream in the most severe cases. These air bubbles can cause an arterial gas embolism, which is generally lethal once they enter the bloodstream. This is why you should never try to hold your breath while diving.
When You’re Done, Ascend Safely
Being careful to ascend gradually and securely is almost as crucial as breathing continually. The nitrogen absorbed into the bloodstream at depths does not have time to dissolve back into solution when the pressure decreases on the trip to the surface if divers exceed a safe ascent velocity. Decompression illness is caused by bubbles forming in the bloodstream. Maintain an ascending rate of no more than 30 feet per minute to avoid this. If you dive with a computer, you’ll be warned if you’re ascending too quickly, but if you don’t have one, a general rule of thumb is to ascend no quicker than your smallest bubble.

Double-Check If Everything Is Working Fine
When it comes to checking your gear before a dive, don’t be a slacker. Your equipment is critical to your survival underwater. So, conduct a thorough buddy check. If either your or your buddy’s equipment fails, it might result in a life-threatening situation for both of you. Make sure you understand how to operate your equipment. The bulk of equipment-related mishaps occur because divers are unsure of how the equipment works, rather than because the equipment breaks.

Don’t Go Beyond Your Limit
Overall, keep in mind that diving should be enjoyable. Never put yourself in circumstances that you don’t want to be in. Call it if you aren’t physically or mentally capable of diving. It’s easy to give in to peer pressure, but you must always determine whether or not to dive for yourself. If the conditions are risky on a given day, don’t be afraid to cancel a dive or alter the location. Depending on changes in surface conditions, temperature, and current, the same place maybe within your capabilities one day and not the next. Never try a dive that is beyond your level of qualification.
