At What Depth Is Freediving Dangerous?

August 18, 2022 4 min read

There are several reasons that freediving can be dangerous. Read on to learn about decompression sickness, nitrogen narcosis, blackouts, and lung over-expansion injuries. If you're interested in diving, make sure to learn more about the risks. Freediving is a great way to get active on your vacation, but it is not without risk.

Freediving Causes Nitrogen Narcosis

There are several factors that can cause Nitrogen narcosis in freedivers. This condition is caused by excessive pressure and nitrogen in the bloodstream. It usually clears up when the diver returns to shallow water. To avoid the effects of nitrogen narcosis, follow the tips below. It can also be a symptom of other conditions. Below, we will discuss how to treat it.

The most important step in avoiding narcosis during a freediving dive is recognizing the symptoms of narcosis while you're at the depth. Fortunately, most symptoms will clear up within a few minutes of ascent. If you've already experienced the symptoms, however, abort the dive and get help from a professional.

It Causes Decompression Sickness

Free diving is a risky sport for many people, and many experts warn that the danger of decompression sickness is more likely to occur at a deeper depth than one might think. As the partial pressure of nitrogen increases while you are underwater, the body's ability to absorb oxygen decreases. This condition is also known as decompression sickness, and it can develop as shallow as 30 meters. It causes mood swings, altered senses, and even mental impairment.

A diver can suffer decompression sickness by forcing themselves to surface too soon. This condition can range from mild to fatal. It happens when the body releases excess nitrogen too quickly, causing air bubbles to form in the bloodstream and blocking critical blood vessels. When free diving, be sure to allow the body to complete the decompression in the water before rising. Divers with insufficient flexibility in their diaphragm, or those who are tense can also suffer from decompression sickness.

It Causes Lung Over-Expansion Injuries

The most common cause of lung over-expansion injuries is breathing air that has reached a pressure greater than the alveolar volume. Pulmonary barotrauma can also occur when an explosion occurs during the decompression of a pressurised aircraft. The Space Shuttle Columbia disaster in 2003 illustrates the risk of pulmonary barotrauma in freedivers.

The alveoli in the lungs are very delicate and can rupture as soon as 70 mmHg or 2 psi of pressure increases in the alveoli. A full breath is enough to rupture the alveoli, but deep freediving can increase the risk of lung over-expansion injuries. Therefore, it is important to practice safety measures when freediving and wear a dry diving suit.

It Causes Blackouts

You may be asking yourself, "At what depth is freediving dangerous? It causes blackouts?" If you haven't experienced a blackout, you may think that it's a non-issue. Many freedivers don't think about the risk of blackouts, and if they did, they'd be fine. Fortunately, it can happen to you, too.

Blackouts are the result of low oxygen levels. A trained buddy can bring a diver to the surface and revive them. The danger of blackouts is greatest in the first few meters of freediving. Nonetheless, blackouts do happen, and it's a good idea to plan for these situations and have a gas supply at hand. While this isn't likely to happen to you, it's always a good idea to have a backup plan in case something goes wrong.

It Requires Physical and Psychological Skills

At what depth is freediving dangerous? The answer depends on how much you know about the sport. A professional freediving instructor can teach you the basics of safe diving, but a beginner should be careful. Freediving is dangerous because you can run out of air, get stuck, or hit your head. Blackouts are rare but can happen. You should always dive with a buddy. Also, keep a plan for a gas emergency.

The maximum depth at which freediving is safe is determined by an individual's comfort level. Most freedivers will try diving deeper, and will eventually find a comfortable level. The depth that is dangerous is any depth beyond what the individual has previously mastered. There's no reason not to try it, but don't do it without a safety diver with you. A buddy or two will be there for backup in case you have a problem.

It Requires Discipline

At what depth is freediving dangerous? This is an important question to ask yourself and your friends before venturing out into the ocean. As with any activity, aside from the possible health benefits, freediving has its risks. You could run out of air, hit your head, or get stuck somewhere. These events can occur to anyone, regardless of their training or experience. It's impossible to know for sure when you might experience one of these scenarios, so it's important to always dive with a buddy.

As with any activity, freediving requires training to maintain a high level of fitness. Free divers must maintain a high level of fitness, which is essential to ensuring a safe and comfortable dive. The human body performs at its optimal level when it's well-rested and well-conditioned. While short trips underwater are usually not dangerous, extending dives beyond the safe limits is a major concern. Modern freediving courses incorporate techniques to relax and reduce jerky movements, which prolongs the dive.
