Hook Breathing

How to do it

1. Sit or stand comfortably. Relax your shoulders, jaw and belly.
2. Breathe in gently through your nose for 2 seconds.
3. Hold for 2 seconds with your throat and belly soft. Do not bear down or squeeze.
4. Breathe out easily for 2 seconds. Let the air go; do not push it.
5. Repeat for 3 rounds, or more if you chose a longer session.
6. Finish with a few normal breaths.

Benefits

• Steadier in 18 seconds

  Three short, even breaths give a racing moment a simple shape. You'll feel steadier by the third breath.

• A reset that fits anywhere

  It is short and quiet enough for a desk, a locker room or the minute before you walk into a meeting.

• The diver's rhythm, without the pressure

  Spoon keeps the in, hold, out shape of freedivers' recovery breathing and drops the straining, so there is nothing to get wrong.

• A calm close to breath-hold training

  Add it after a dry CO2 or O2 Tables session to come back to easy breathing.

What the research says

For pilots, hook breathing is the breathing half of the anti-G straining maneuver (AGSM): a breath of under a second, then a strain against a closed throat (a Valsalva maneuver) to raise blood pressure, while the legs and trunk stay tensed^[1]. In U.S. Navy training, the pilot closes the throat by saying "hick", bears down for 2.5 to 3 seconds, then exhales and inhales in a second or less, and repeats^[2]. The first muscular straining maneuver was proposed in the UK in 1933, and a 2026 review reports broad agreement that AGSM is the most effective technique to prevent G-induced loss of consciousness^[1].

Freedivers use hook breathing right after surfacing: a full breath in, then an interrupted or resisted exhale that builds pressure in the lungs^[3][4]. In a crossover study of 22 male freedivers after 30 m dives, it helped only the 5 who recovered slowly: they reached 95 percent oxygen saturation in 60 seconds on average with hook breathing, against 120 seconds with normal breathing, while the other 17 showed no difference^[3]. In 13 trained divers after 40 m dives, oxygen saturation was higher with hook breathing only between 30 and 45 seconds after surfacing^[4].

Spoon's short, unstrained pattern has not been studied. The pilot research does not apply, since there is no G-force to fight, and the diving trials tested pressurized breathing after real dives. Spoon's version is a gentle reset, not dive recovery.

One name, three techniques

• Pilots (AGSM): a quick breath, then about 3 seconds of straining against a closed throat while tensing the legs and trunk, repeated under G-force. Learned in supervised flight training.
• Freedivers (recovery breathing): a full breath, then a pressurized or resisted exhale, right after surfacing, with a buddy watching.
• Spoon (Hook Breathing): 2 seconds in, 2 held softly, 2 out. No strain, no pressure, no water.

Tips

• Keep the hold passive: throat relaxed, belly soft, nothing to brace against.
• Breathe out slowly and let the air leave on its own.
• Choose 60 or 120 seconds for a longer, calmer reset.
• Use it after a hard set, a tense call or a dry breath-hold session.
