How do divers deal with ear pressure?

Most divers are taught to equalize by pinching their nose and blowing gently. This gentle pressure opens the eustachian tube and flows air gently to the middle ear. You may do it already – at the surface, exhale fully as much as you can, squeezing out as much as you can, then pinch your nose and gently pop your ears.

How can freedivers go so deep?

So how is it that freedivers are able to dive so deep and last so long without taking a breath? One reason is the diving reflex, an evolutionary adaptation that enables seals and dolphins to dive deep and stay underwater for extended periods by slowing and/or shutting down some physiological functions.

How do free divers equalize?

The most common equalization technique that Scuba divers and people new to freediving use are the Valsalva maneuver. You simply pinch your nose and create pressure from your diaphragm by trying to exhale through your nostrils against your pinched nose.

How can I improve my free dive?

The key to advancing and lasting longer underwater is to get used to taking slow, deep breaths. Breathe in for five seconds, and then breathe out for 10-15 seconds. Make sure that you breathe out for much longer than you breathe in to avoid hyperventilating. When you have this breathing pattern down, record your pulse.

How do you do the Frenzel maneuver?

To perform the frenzel technique:

1. Pinch your nose.
2. Fill your mouth up with a little bit of air.
3. Close the epiglottis.
4. Move the soft palate to the neutral position.
5. Use the tongue as a piston and push air towards the back of your throat.

How deep can you dive without hurting your ears?

The technique is only effective up to 30 meters, however, so there are limitations. To perform the Valsalva Maneuver: Using your thumb and forefinger, pinch your nose cavity closed. Attempt to exhale with force through your nose as if it were opened.

What is the deepest free dive recorded?

214m
The record for deepest no-limit freediving is 214m (702ft), held by Austrian world champion Herbert Nitsch, who set the record on 14 June 2007 in Spetses, Greece.
