Drysuit Squeeze: The Underwater Challenge


Drysuit squeeze – a term that resonates with divers and evokes a sense of both excitement and concern. As you prepare to embark on your next aquatic adventure, comprehending the intricacies of drysuit squeeze becomes paramount for a safe and enjoyable diving experience. In this comprehensive guide, we will delve deep into the world of drysuit squeeze, exploring its definition, the science behind it, signs and symptoms, prevention strategies, and, finally, concluding with essential insights to ensure you stay warm, dry, and comfortable during your underwater exploits. So, let’s take the plunge!

Demystifying Drysuit Squeeze

What is Drysuit Squeeze?

Drysuit squeeze, sometimes referred to as drysuit squeeze syndrome, is a phenomenon divers often encounter when they descend into watery depths. This sensation arises from the compression of the air trapped inside the drysuit as the diver goes deeper into the water. The increasing water pressure at greater depths exerts a force on the air within the drysuit, resulting in discomfort, potential pain, and even health risks for the diver.

To put it simply, drysuit squeeze feels like being tightly hugged by the underwater environment, and this discomfort can range from minor irritation to significant pain. Its impact goes beyond the physical sensations and can profoundly influence the overall diving experience.

The Science Behind Drysuit Squeeze

To truly grasp drysuit squeeze, you need to acquaint yourself with the science behind it. As you descend underwater, the hydrostatic pressure rises, causing the air within your drysuit to compress. The pressure of the water increases as you go deeper, leading to the compression of the air within your ears and sinuses, which, in turn, results in the discomfort associated with drysuit squeeze.

This pressure increase can be likened to the experience of ascending a mountain. As you ascend, the air pressure decreases, and your ears pop. In the underwater realm, the opposite occurs. As you descend, the increasing water pressure compresses the air within your ears and sinuses, potentially causing pain, especially if the pressure isn’t equalized.

The Importance of Equalization

Equalization is the diver’s secret weapon against drysuit squeeze. By equalizing the pressure inside your ears and sinuses, you can alleviate the discomfort and prevent potential injuries. We’ll explore the techniques and methods you can use for effective equalization.

Equalization involves adjusting the pressure inside your ears and sinuses to match the surrounding water pressure. When you dive, it’s essential to perform this technique regularly to ensure that the pressure inside and outside your body remains balanced.

One common equalization technique is known as the Valsalva maneuver, where you gently blow against your closed nostrils to equalize the pressure in your ears. Another technique, the Frenzel maneuver, involves moving the tongue and jaw to achieve the same effect. It’s crucial to learn and practice these techniques under the guidance of a certified diving instructor to ensure you’re doing them correctly.

Recognizing Drysuit Squeeze

Signs and Symptoms

Before you can effectively deal with drysuit squeeze, you must be able to recognize the telltale signs. From ear pain to facial discomfort, understanding the symptoms is the initial step in addressing the issue before it escalates.

  1. Ear Pain: The most common and noticeable symptom of dry-suit squeeze is ear pain. This pain can range from mild pressure to sharp, shooting discomfort. Ignoring this pain can lead to more severe issues, such as barotrauma, which can cause damage to your eardrums.
  2. Facial Discomfort: Drysuit squeeze can also cause discomfort in the facial area. This discomfort may include pressure around the eyes, nose, and forehead. It’s crucial to be attentive to these sensations, as they can be early indicators of a squeeze.
  3. Difficulty Equalizing: If you find it challenging to equalize the pressure in your ears and sinuses, it’s a sign that drysuit squeeze may be affecting you. This difficulty can lead to increased pain and discomfort as you descend further into the water.

Emergency Procedures

In severe cases, drysuit squeeze can become a serious problem. You’ll want to be prepared with emergency procedures to manage the situation effectively. Learning when and how to ascend slowly can make all the difference.

  1. Ascend Slowly: If you experience intense discomfort or pain due to drysuit squeeze, the best course of action is to ascend slowly. By ascending, you reduce the water pressure that’s causing the squeeze in the first place.
  2. Signal Your Buddy: If you’re diving with a buddy, communicate your discomfort and intention to ascend. They can assist you and provide support during the ascent.
  3. Seek Immediate Medical Attention: In severe cases where pain is intense and doesn’t subside, it’s crucial to seek immediate medical attention. Barotrauma and other complications can result from ignoring the issue.

Strategies for Preventing Drysuit Squeeze

Perfecting Your Buoyancy

Controlling your buoyancy is not only a core skill for divers but also an effective strategy for preventing drysuit squeeze. Proper buoyancy reduces stress on your body and contributes to a more enjoyable dive.

  1. Weight Distribution: Ensure that your weights are properly distributed. Imbalanced weights can lead to issues with buoyancy, making it harder to control your position in the water.
  2. Dive Practice: Regular practice can help improve your buoyancy control. Familiarize yourself with your drysuit’s buoyancy characteristics, and practice ascending and descending to gain confidence in your abilities.
  3. Master Your Equipment: Understanding your diving equipment is crucial. Know how your drysuit functions and how to manage the air inside it effectively.

Suiting Up Right

Selecting the right drysuit and ensuring it fits properly is crucial in minimizing the chances of experiencing drysuit squeeze. We’ll discuss the importance of a well-fitted drysuit and how it can improve your overall diving experience.

  1. Drysuit Selection: When choosing a drysuit, consider factors like the type of diving you’ll be doing and the water temperature. For cold-water dives, a thicker drysuit with sufficient insulation is essential.
  2. Proper Fit: Your drysuit should fit snugly but not be overly tight. A well-fitted drysuit reduces the risk of air getting trapped inside, which is a leading cause of drysuit squeeze.
  3. Inflate Carefully: When inflating your drysuit, do so gradually. Overinflating can lead to an uncomfortable or unsafe diving experience.

Getting Proper Training

Diving isn’t just about plunging into the depths; it’s about having the knowledge and skills to do so safely. Proper training is a fundamental aspect of preparing for and preventing drysuit squeeze.

  1. Certified Instructors: Seek out certified diving instructors who have experience in teaching drysuit diving. They can provide invaluable guidance on how to handle your drysuit, equalize properly, and manage various diving scenarios.
  2. Diving Courses: Enroll in diving courses that specifically cover drysuit diving. These courses provide hands-on experience and in-depth knowledge of drysuit management.
  3. Continual Learning: Diving is a dynamic and evolving field. Stay updated with the latest techniques, technologies, and safety measures by participating in continual learning and advanced diving courses.


In conclusion, drysuit squeeze is an inevitable challenge for divers. However, with the right knowledge, training, and equipment, you can effectively manage and even prevent it. Your safety and the enjoyment of your underwater adventures depend on your ability to understand, recognize, and respond to drysuit squeeze. So, as you embark on your next Blog title expedition, remember these tips and dive with confidence, knowing you’re well-prepared to face the depths.
