Which is better, freediving or scuba diving?
Whether you’ll feel safer scuba or free diving comes down to personal preference. Free divers love that limits are constantly being stretched, and that dedication and practise can create incredible possibilities for underwater exploration. A common misconception is that freediving is inherently more dangerous than scuba diving. However, the reality is quite different. Freediving, by its very nature, involves fewer risks as it requires minimal equipment and allows divers to surface anytime they feel the need to breathe.Never hold your breath. This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls.Provided you are flexible enough or do not dive very deep, your lungs simply reduce in volume as you descend. So you usually only need to equalize the pressure in your ears, sinuses and mask.Professional divers always practice and also take a deep breath before diving. By holding their breath, the divers can expel carbon dioxide out of their bodies when stay underwater. Almost all healthy adults easily hold their breath for one to two minutes.Scuba divers are at risk for a condition known as Diver’s Mouth Syndrome — a painful problem that affects the mouth and jaw due to the unique pressures and equipment used underwater. By visiting your dentist before diving, you can ensure that your teeth, gums, and jaw are in good health.
Why can freedivers go deeper than scuba divers?
Lung Compression: As freedivers go deeper, the water pressure compresses their lungs, making them smaller but denser with oxygen. Oxygen Conservation: Trained freedivers can use oxygen more efficiently, allowing them to stay underwater longer. As a freediver descends, increasing water pressure compresses the lungs within the chest cavity. If this compression exceeds the body’s ability to compensate, it may cause stress or damage to the lung tissue, like small leaks or tears.
What is the 120 rule in scuba diving?
Here’s how it works: Your max depth (in feet) + your bottom time (in minutes) should be less than or equal to 120. That’s it. So if you plan to dive to 60 feet, the rule says you shouldn’t stay down longer than 60 minutes. It’s mainly for recreational divers using air, not Nitrox or other fancy gas mixes. Here’s how it works: Your max depth (in feet) + your bottom time (in minutes) should be less than or equal to 120. That’s it. So if you plan to dive to 60 feet, the rule says you shouldn’t stay down longer than 60 minutes.Because excess nitrogen remains dissolved in the body tissues for at least 12 hours after each dive, repeated dives within 1 day are more likely to cause decompression sickness than a single dive.Going back to depth and ascending fast could affect the nitrogen off-gassing, and as we know, this is what triggers decompression sickness. Scuba divers generally follow the same rules for freediving as for flying: Wait 12 hours after one dive, and 18 hours after two or more.
Why can’t you freedive after scuba?
The risk for depths beyond 50 feet increases before or after scuba diving — before, because of potential exertion and middle-ear stress issues, and after, because of exertion, shunting and, increasing as a function of depth, direct gas loading from the freediving. The percentage of accidents in freediving is very small compared to scuba diving. Many people don’t understand the urge to breathe and think that it is something you cannot control; therefore they assume that diving deep on a single breath of air is a very dangerous thing to do.Individuals should not dive if they have cardiac disease that might result in incapacity underwater (e.
