How to Hold Your Breath Longer for Freediving: A Comprehensive Guide

Freediving: A union of man and the aquatic world, where one dives deep into the blue, powered only by a single breath. This pure form of underwater exploration is as mesmerizing as it is demanding. Central to its practice is the art of breath-holding.

In the world of freediving, the ability to hold one’s breath for extended periods can be the difference between skimming the surface and plumbing the depths.

And whether you are doing it for the sport and the performance itself or, like me, to be able to explore the underwater world without all the bulky equipment, it all boils down to how long you can hold your breath. The importance of mastering this skill cannot be overstated, both for the experience it offers and the safety it ensures.

Understanding the Basics of Breath-holding

The Science Behind Holding Your Breath

When you take in a deep breath and submerge, your body instinctively begins to adapt. The heart rate slows down, a phenomenon called the mammalian dive reflex, conserving oxygen and directing it to crucial organs like the brain and heart.

As oxygen levels decrease and carbon dioxide (CO2) levels rise, the urge to breathe intensifies. Understanding and controlling this urge is essential for freedivers.

Static Apnea vs. Dynamic Apnea

These are two foundational practices in freediving. Static apnea refers to holding your breath while remaining still, typically practiced in a pool. It’s a test of pure breath-holding capability.

On the other hand, dynamic apnea involves traveling distance underwater, like horizontal swimming in a pool, while holding your breath. While static focuses on duration, dynamic apnea trains the diver to manage breath while in motion.

Risks and Safety Precautions

Potential Dangers: Holding your breath might seem benign, but when pushed to extremes, it carries real risks. Extended breath-holding can lead to hypoxia, where the body is deprived of adequate oxygen supply. This can result in a blackout underwater, a dangerous situation for any diver.

The Buddy System: A golden rule in freediving is to never dive alone. The presence of a buddy ensures immediate assistance in case of any emergencies. They can recognize signs of distress and provide the necessary support, making the diving experience safer and more enjoyable.

Recognizing Warning Signs: A good freediver knows their body and is alert to any warning signs. Early signs of hypoxia include tingling in the limbs, dizziness, and narrowed vision. Shallow water blackout can occur during ascent, typically when a diver has consumed too much oxygen during the dive. Recognizing these symptoms and ascending slowly and cautiously can help prevent such occurrences.

Breath-holding Techniques

Diaphragmatic Breathing

Explanation and Benefits: Diaphragmatic breathing, often referred to as “deep breathing,” involves the contraction of the diaphragm, a muscle located horizontally between the thoracic and abdominal cavities. By using this muscle effectively, you can increase your lung’s oxygen capacity, calm the mind, and prepare the body for a prolonged dive.

Step-by-step Technique:

  1. Sit or lie down in a relaxed position.
  2. Place one hand on your chest and the other on your abdomen.
  3. Inhale slowly through the nose, ensuring the diaphragm (not the chest) inflates with enough air to stretch the lungs. You should feel the hand on your abdomen rise.
  4. Exhale slowly through pursed lips, once again observing the hand on your abdomen descend.
  5. Repeat this process for a few minutes, focusing on the rhythm and depth of your breaths.

Full-lung Breathing

Explanation and Benefits: This technique involves filling the lungs to their maximum capacity. By using both chest and diaphragmatic breathing, you ensure optimal oxygen intake, which is crucial for extended breath-hold times.

How to Perform:

  1. Begin with the diaphragmatic breathing technique, filling the lower part of the lungs.
  2. Continue the inhalation by expanding the chest, further filling the lungs.
  3. Finish the inhalation by raising the shoulders and collarbone, ensuring the lungs are filled to capacity.
  4. Hold for a moment, then exhale smoothly and slowly, reversing the order: collarbone, chest, and then diaphragm.

Purge Breathing

Explanation: Purge breathing involves a series of quick, forceful exhalations followed by passive inhalations. This technique helps in expelling stale air from the lungs, increasing the intake of fresh oxygen on the subsequent breath.

When to Use: It’s best utilized just before diving to saturate the bloodstream with as much oxygen as possible. However, excessive purge breathing can lead to hyperventilation and should be practiced with caution.

Training Techniques to Increase Breath-hold Duration

CO2 and O2 Tables

Explanation and Benefits: These are structured breath-hold training schedules that help divers acclimate to higher levels of CO2 and lower levels of O2. This increases tolerance to both gases, crucial for longer dives.

Sample Tables for Training:

  • CO2 Table: After a 2-minute breath-hold, rest for 2 minutes. On each subsequent round, decrease the rest period by 15 seconds while maintaining a 2-minute breath-hold.
  • O2 Table: After a 1-minute breath-hold, rest for 2 minutes. On each subsequent round, increase the breath-hold duration by 15 seconds while keeping the rest period constant.

Static Apnea Training

Benefits: Helps in increasing pure breath-hold capacity, improving mental strength, and refining relaxation techniques.


  • Relax and perform your preferred breathing technique.
  • Take a deep breath and hold, lying still in a pool or on dry land.
  • Once you feel the urge to breathe, try to relax further, diverting your mind from the sensation.
  • When you can no longer hold, exhale slowly and take a few recovery breaths.

Dynamic Apnea Training

Benefits: Enhances underwater swimming skills, improves technique, and increases breath-hold capacity during movement.


  1. After a thorough warm-up, swim underwater in a pool for as long as you comfortably can.
  2. Focus on streamlined swimming and efficient movement.
  3. Upon surfacing, recover fully before attempting another dynamic apnea swim.

Dry Training Exercises

Benefits: Allows for regular training without the need for water, making it convenient and versatile.

Sample Exercises:

  • Apnea Walks: Take a full breath and hold it, then walk at a steady pace. Aim to increase the distance with each session.
  • Static Holds: Perform static apnea but in a seated or lying position on dry land.
  • Diaphragm Flexing: Inhale fully, then exhale just a small amount. Flex the diaphragm in and out, increasing lung flexibility and strength.

Remember, each individual’s capacity is different. It’s crucial to listen to your body, progress at your own pace, and always prioritize safety. Train with a buddy!
