How to Hold Your Breath Longer for Freediving

Freediving is a form of underwater diving that relies on breath-holding rather than the use of breathing equipment such as scuba gear.

Freedivers can explore the depths of the oceans with minimal impact and enjoy magical encounters with marine life .

Freediving can also be a competitive sport, where divers attempt to attain great depths, times, or distances on a single breath . One of the most important skills for freediving is the ability to hold your breath for long periods of time. Breath-holding not only determines how far you can dive, but also how safe and comfortable you are underwater. Holding your breath for too long can lead to serious risks such as hypoxia, blackout, or drowning So, how can you improve your breath-hold for freediving? In this article, we will cover some

of the factors that affect your breath-hold, some of the techniques and exercises that can help you extend it, and some of the safety rules and precautions that you should follow. Factors that Affect Your Breath-Hold There are many factors that can affect your breath-hold, both physiological and psychological. Some of the main ones are:

  • Oxygen consumption. Oxygen is the fuel that your body needs to function, especially your brain and heart. The more oxygen you consume, the faster you deplete your oxygen reserves in your lungs and blood. Oxygen consumption depends on many variables, such as your metabolic rate, muscle activity, body temperature, etc. The lower your oxygen consumption, the longer you can hold your breath.

  • Carbon dioxide tolerance. Carbon dioxide is the waste product that your body produces when it uses oxygen. Carbon dioxide accumulates in your blood and tissues as you hold your breath, and it triggers the urge to breathe. Carbon dioxide tolerance

is the ability to resist this urge and cope with the discomfort and pain that it causes. The higher your carbon dioxide tolerance, the longer you can hold your breath.

  • Relaxation. Relaxation is the key to reducing oxygen consumption and increasing carbon dioxide tolerance. Relaxation involves both physical and mental aspects. Physically, you need to relax your muscles and minimize any unnecessary movements or tension. Mentally, you need to calm your mind and emotions and avoid any stress or anxiety. Relaxation helps you lower your heart rate, blood pressure, and energy expenditure, as well as increase your focus and concentration.

  • Equalization. Equalization is the process of adjusting the pressure in your ears and sinuses to match the ambient pressure as you dive deeper. Equalization is essential for preventing ear injuries and pain, as well as maintaining balance and orientation. Equalization also affects your breath-hold indirectly, as it requires you to use some of the air in your lungs to fill your ears and sinuses. The more efficient your equalization technique, the less air you waste and the longer you can hold your breath.

Techniques and Exercises to Improve Your Breath-Hold

There are many techniques and exercises that can help you improve your breath-hold for freediving. Some of them are:

  • Breathing exercises. Breathing exercises are designed to improve your lung capacity, oxygen delivery, carbon dioxide removal, and diaphragm strength. Breathing exercises can be done on land or in water, before or after diving, or as a separate training session. Some examples of breathing exercises are deep breathing, box breathing, diaphragmatic breathing, etc.

  • Apnea training. Apnea training is the practice of holding your breath for a certain duration or distance under specific conditions. Apnea training can be done on land or in water, with or without fins, static or dynamic, etc. Apnea training helps you increase

your oxygen efficiency, carbon dioxide tolerance, relaxation skills, and mental toughness. Some examples of apnea training are CO2 tables3, O2 tables3, max attempts3, etc.

  • Cross-training. Cross-training is the practice of engaging in other physical activities that complement freediving. Cross-training can help you improve your overall fitness, endurance, strength, flexibility, coordination, etc. Cross-training can also help you prevent injuries and boredom from overtraining. Some examples of cross-training are swimming3, yoga4, running3, etc.

Safety Rules and Precautions for Freediving Freediving is a rewarding but risky sport that requires proper knowledge, skills, and equipment. To ensure your safety and enjoyment while freediving, you should follow some basic rules and precautions:

  • Never dive alone. Diving alone is one of the most common causes of fatal accidents in freediving3. You should always dive with a buddy who can watch over you and assist you in case of an emergency. Your buddy should be trained and experienced in freediving, and should stay within your sight and reach at all times. You should also communicate your dive plan and signals with your buddy before each dive.

  • Never hyperventilate. Hyperventilation is the practice of breathing rapidly or deeply before diving to increase your oxygen levels and reduce your carbon dioxide levels. Hyperventilation is dangerous because it can mask your urge to breathe and make you prone to blackouts3. You should avoid hyperventilation and instead breathe normally or slightly slower before diving.

  • Never push your limits. Pushing your limits is the practice of diving beyond your comfort zone or capabilities to achieve a personal best or a competitive edge. Pushing your limits is dangerous because it can increase your oxygen consumption, carbon dioxide accumulation, stress, and fatigue, and make you prone to injuries or blackouts3. You should respect your limits and dive within them, and only increase them gradually and safely with proper training and guidance.

  • Never ignore the warning signs. Warning signs are the physical and mental indicators that tell you that you are running out of oxygen or that something is wrong. Warning signs can vary from person to person, but some common ones are contractions, tingling, dizziness, blurred vision, loss of motor control, etc3. You should never ignore the warning signs and instead abort your dive and return to the surface as soon as possible.


Freediving is a fascinating sport that allows you to explore the underwater world with nothing but your breath. To improve your breath-hold for freediving, you need to understand the factors that affect it, practice the techniques and exercises that enhance it, and follow the safety rules and precautions that protect it. By doing so, you can enjoy freediving more and achieve your goals safely and comfortably. I hope you like this article about the breath hold in freediving.
