How to Equalize Ears Freediving: A Comprehensive Guide


Freediving, the art of exploring the depths of the ocean with a single breath, offers a unique and exhilarating underwater experience. However, as you descend into the mesmerizing world beneath the waves, you encounter a significant challenge — equalizing your ears. In this comprehensive guide, we will delve into the essential techniques and strategies for successfully equalizing your ears while freediving, ensuring a safe and comfortable journey into the deep blue.

The Importance of Ear Equalization

Understanding Ear Pressure

Before we dive into the techniques, let’s grasp the importance of ear equalization. As you descend underwater, the water’s pressure increases, exerting force on your eardrums. Without equalization, this pressure differential can cause discomfort, pain, or even injury to your ears. Equalizing your ears is the key to balancing this pressure, allowing you to explore the underwater world with ease.

Ear Equalization and Safety

Safety is paramount in freediving, and ear equalization plays a pivotal role in ensuring your well-being during underwater descents. Failure to equalize your ears correctly can lead to a condition known as barotrauma, which can result in ear pain, eardrum injuries, and in severe cases, even hearing loss. Understanding the techniques and practicing them diligently is not just about comfort but also about protecting your hearing and preventing potential harm.

Mastering Equalization Techniques

The Valsalva Maneuver: A Fundamental Technique

The Valsalva maneuver is one of the most commonly used methods for equalizing ear pressure while freediving. It serves as the foundation for many divers. Here’s how to perform it effectively:

  1. Begin by pinching your nostrils closed with your thumb and forefinger, effectively sealing them.
  2. Take a small breath and gently exhale through your nose while keeping your mouth closed.
  3. This exhalation creates pressure behind your eardrum, equalizing the pressure inside your ear.

Exploring the Toynbee Maneuver

If you find the Valsalva maneuver challenging or ineffective, you can explore an alternative technique—the Toynbee maneuver:

  1. Start by pinching your nostrils closed, just as in the Valsalva maneuver.
  2. Now, swallow while keeping your mouth closed.
  3. This swallowing action helps open your Eustachian tubes, allowing air to flow and equalize the pressure in your ears.

The Frenzel Maneuver: An Advanced Technique

For those looking to elevate their equalization skills, the Frenzel maneuver is a valuable technique:

  1. Seal your nostrils by pinching them shut, as in the previous methods.
  2. While keeping your mouth closed, create a “k” or “g” sound in the back of your throat.
  3. This sound production compresses the air in your mouth and pushes it into the Eustachian tubes, effectively equalizing the pressure in your ears.

Exploring the Lowry Technique

The Lowry technique is another advanced equalization method that can be particularly useful for freedivers aiming to master their ear equalization skills. It involves the following steps:

  1. Pinch your nostrils shut to seal them.
  2. Gently push your jaw forward while keeping your mouth closed.
  3. This action helps open the Eustachian tubes and equalize the pressure.
How to Equalize Ears Freediving

Descend Gradually

As you begin your freedive, remember that patience is your ally. Descend gradually, taking your time to acclimate to the increasing water pressure. Rushing can make equalization more challenging, so proceed calmly and steadily into the depths.

Equalization Techniques for Depth

Equalizing your ears during a deep freedive presents unique challenges due to the increased pressure. To overcome these challenges, consider these techniques:

  1. Mouthfill Technique: This advanced technique involves holding a small amount of water in your mouth while equalizing. The added water pressure can aid in equalizing your ears at greater depths.
  2. Hands-Free Equalization: Some experienced freedivers can equalize their ears without using their hands. This technique, known as hands-free equalization, requires exceptional control over the muscles used for equalization.

Frequent Equalization

One of the key principles of successful ear equalization while freediving is to equalize frequently. Don’t wait until you feel discomfort or pain. Start equalizing as soon as you begin your descent and continue to do so every few feet or meters. This proactive approach helps maintain equilibrium and minimizes the risk of ear-related issues.

Listening to Your Body

Paying Attention to Signals

While freediving, it’s crucial to stay attuned to your body’s signals. If you experience pain, discomfort, or a sense of blockage in your ears, do not ignore it. These sensations are your body’s way of communicating that it’s time to address the pressure imbalance. When you encounter such signals, pause your descent, and ascend slightly. Attempt equalization again before continuing your journey into the depths.

The Role of Relaxation

Staying Relaxed and Calm

Tension and anxiety can hinder your equalization efforts. To equalize your ears effectively, maintain a relaxed and calm demeanor. Tension can affect the muscles responsible for equalization, making the process more challenging. As you descend into the underwater world, focus on maintaining a tranquil state of mind.

Practice Makes Perfect

The Importance of Practice

Equalization is a skill that improves with practice. Whether you’re a beginner or an experienced freediver, dedicating time to hone your equalization techniques is essential. Regular practice enhances your ability to equalize effortlessly, even in challenging conditions.

Seeking Guidance from Experts

If you’re new to freediving or struggling with equalization, consider seeking guidance from a certified freediving instructor. These experts can provide personalized instruction, tailored techniques, and valuable insights to help you overcome any challenges you may face.

Equalization Tips for Different Freediving Disciplines

Static Apnea

Static apnea, a discipline where freedivers hold their breath without moving, presents its own equalization challenges. To excel in static apnea, consider:

  1. Pre-Breathe: Take several relaxed breaths before your breath-hold attempt to ensure your Eustachian tubes are open and equalized.
  2. Equalize During Static Apnea: Continue equalizing gently during your static apnea attempt to maintain ear pressure balance.

Dynamic Apnea

Dynamic apnea, where freedivers swim horizontally underwater without fins, also requires effective ear equalization. To excel in dynamic apnea, remember:

  1. Streamline Position: Maintain a streamlined body position to minimize water resistance and reduce the need for forceful equalization.
  2. Practice Dry Equalization: Dry equalization techniques, where you practice equalization on dry land, can improve your skills and reduce the need for frequent underwater equalization.

Equalization Gear and Accessories

Freediving Masks

Investing in a high-quality freediving mask is essential for successful ear equalization. Look for a low-volume mask with a soft silicone skirt that provides a snug but comfortable seal around your nose, allowing for efficient equalization.

Nose Clips

Nose clips are useful tools for freedivers, especially when practicing dry equalization techniques. They help you focus on equalization without worrying about water entering your nostrils.


Earplugs designed for freediving can assist in keeping water out of your ears, minimizing the risk of infection and enhancing equalization comfort.


In the world of freediving, the ability to equalize your ears is a fundamental skill that ensures both comfort and safety as you explore the mesmerizing depths of the ocean. By understanding the techniques, practicing regularly, and listening to your body’s signals, you can master the art of ear equalization and embark on incredible underwater adventures with confidence and ease. So, prepare to take the plunge, embrace the wonders of the deep, and let ear equalization be your trusted companion on your freediving journey.
