Updated May 2026: This guide has been expanded with additional instructor advice, equalisation troubleshooting tips, safety notes and dive-trip preparation guidance.

Learning how to equalize ear pressure when scuba diving is one of the most important skills every diver needs to master… Equalizing your ears is one of the most essential — and often most frustrating — parts of scuba diving. Even the most experienced divers occasionally struggle with it. As a dive instructor who’s taught hundreds of students across Asia (and someone with tiny Eustachian tubes myself), I’ve experienced the challenge firsthand.

Over the years, I’ve learned that equalisation isn’t just about technique — it’s about preparation, relaxation, and awareness of your own body. Here are five proven equalisation tips that can make a world of difference underwater.

💡 Note: This is a simplified version of my full “Equalisation Master Guide,” which includes advanced drills, anatomical visuals, and pre-dive exercises. You can grab it at the end of this article.

Why Equalization Becomes Harder in Certain Dive Destinations

Equalization does not happen in isolation. Your body, your stress levels, the dive conditions and the way you descend can all affect how easily your ears clear underwater.

After teaching divers across Komodo, Raja Ampat, the Gili Islands and the Maldives, I noticed the same pattern repeatedly: divers who had no major issues in calm, easy conditions would suddenly struggle during multi-day dive trips or in more advanced environments.

This is especially common in destinations with stronger currents, deeper sites, negative entries or repetitive diving schedules.


Fast descents and negative entries

In places like the Maldives and Komodo, some dives require a faster descent so the group can get below the surface current together. This can be challenging for divers who need more time to equalise.

The biggest pressure change happens in the first 10 metres, so if you descend too quickly without equalising early and often, your ears can quickly become painful or blocked.


Stress and jaw tension

Stress has a huge impact on equalisation. When divers feel rushed, cold or anxious, they often clench their jaw without realising it.

This tension can make it harder for the Eustachian tubes to open properly, which may make equalization feel inconsistent or impossible.


Repetitive diving and inflammation

Multi-day dive trips can also make equalisation harder because the body is under more strain. Dehydration, tiredness, sinus irritation, minor inflammation and repeated pressure changes can all build up over several dives.

This is one reason some divers find the first dive of the day easier than the second or third.


Cold water and thermoclines

Cold water can also trigger jaw clenching and facial tension, especially when divers are not wearing enough exposure protection. Even a small amount of tension around the jaw and ears can make equalisation feel more difficult.


Common Equalisation Mistakes Divers Make

  • Waiting until it hurts
  • Descending too fast
  • Forcing pressure
  • Diving congested
  • Holding tension in the jaw
  • Skipping hydration

How to make equalisation easier on dive trips

  • Equalise before you feel pressure
  • Descend slowly whenever conditions allow
  • Signal early if one ear is not clearing
  • Stay hydrated between dives
  • Avoid diving congested or unwell
  • Relax your jaw and breathe slowly
  • Tell your guide before the dive if you equalise slowly

If you know equalisation is sometimes slow for you, speak to the dive centre before booking challenging dives. A good operator can help choose suitable sites, avoid unnecessary stress and give you more time during descent.


Our Top 5  Tips to Avoid Ear Pain and Help with Equalisation

1. Avoid Inflammation Before You Dive

Equalisation begins before you even reach the dive site.

Foods like dairy, alcohol, refined sugar, and processed meals can increase mucus production and inflammation — making your Eustachian tubes swell and block airflow. For divers prone to ear issues, eliminating dairy for two weeks before your trip can dramatically improve results.

🧠 Scientific note: Studies show inflammation in the upper respiratory tract increases barotrauma risk (source: Divers Alert Network).

If you can’t give everything up, just skip the cheese and ice cream — your ears will thank you.


2. Protect Your Ears From Cold Air and AC

Sleeping or relaxing with a fan or air conditioner blowing directly on your head might feel great after a hot dive day, but it can quickly cause sinus irritation and swelling.

If you’ve ever had one ear that equalises more slowly than the other, this could be why.
Try turning your pillow or sleeping position away from airflow to give your sinuses time to rest and recover.


3. Loosen Your Jaw and Neck Muscles

A tight jaw can literally block your Eustachian tubes.

Before every dive, I do a simple masseter massage (the large jaw muscle just in front of your ears) and a few gentle neck rolls. You can also mimic chewing gum or yawning to relax the muscles that help regulate ear pressure.

Small habit — big difference.


4. Try the “Wiggle-Swallow” Method (My Secret Technique)

If the traditional Valsalva manoeuvre doesn’t work for you, try this variation that’s saved countless dives for my students.

When descending:

  1. Use one hand to hold your regulator gently.
  2. Wiggle your jaw side-to-side.
  3. Swallow while tilting your head ear-to-shoulder — alternating sides.

This motion opens the side of your neck and stretches the Eustachian tubes, allowing air to pass more easily. It also helps prevent reverse squeeze when ascending.

This trick alone has helped divers who thought they’d never equalise comfortably again.


5. Equalise Early, Equalise Often

Don’t wait until your ears hurt. Start gently equalizing them with the Valsalva manoeuvre before your descent — even before your giant stride.

As you descend, equalise gently with every breath. It keeps the pressure differences small and easier to manage.

If one ear blocks, never force it. Ascend slightly, relax, and try again. The key is calm breathing and patience. Equalisation is about finesse, not force.


What Is The Valsalva Manoeuvre?

The Valsalva manoeuvre is the equalisation method most divers learn during their Open Water course. Here’s a simple visual guide showing how it works.

Important: Equalisation should always be gentle. If you experience pain, stop descending immediately and ascend slightly until the pressure resolves.


When to Stop & Seek Help

If equalising becomes painful or impossible, stop your descent immediately. Continuing can risk eardrum damage or barotrauma. Persistent issues may indicate sinus inflammation, allergies, or earwax buildup — all worth checking with an ENT or dive physician.

Final Thoughts from an Instructor

As instructors, we see ear issues far more often than you’d think — from beginners to divemasters. The truth? Most cases aren’t caused by “bad ears,” but by stress, poor prep, and rushing descents.

Relaxation and patience solve more equalisation issues than any other technique.
Take your time, stay calm, and remember: the ocean isn’t going anywhere.
