Air hunger anxiety: when you can’t get a full breath

Why do I feel like I can’t get a full breath?

When you’re anxious, your breathing changes in small ways you might not notice: a few extra sighs, a yawn, breaths that sit high in your chest. Each one tops your lungs up a little. When your chest is already fairly full, the next breath has nowhere to go, so it feels blocked or shallow. You try harder, breathe more, and the feeling grows.

Breathing more than you need also lowers the carbon dioxide in your blood a little. That makes breathing feel odd and unsatisfying, and adds the urge to take another big breath. Doctors call this kind of pattern dysfunctional breathing, and frequent deep sighing is one of its recognised forms (Boulding et al. 2016).

It’s more common than most people think. In a UK survey, about 8% of adults without asthma had scores suggesting dysfunctional breathing, and it was far more common in women than in men (Thomas et al. 2005).

How do I stop air hunger anxiety?

Breathe less, not more. It sounds wrong, and it works the other way round from how it feels.

In a study of 47 adults, one 5-minute session of slow breathing with a longer out-breath was followed by lower anxiety, though without a comparison group (Magnon et al. 2021).

If 4 and 6 feels too long, start with the shorter breath below: 2 in, 4 out through soft lips.

Why do I keep yawning to get a deep breath?

Yawns and sighs feel like they should fix it, and for a moment they do: a big breath brings a small wave of relief. Then the urge comes back. Lab experiments suggest sighing can even become a learned habit, reinforced by that brief relief (Vlemincx and Luminet 2020).

When the urge to yawn or sigh comes, try letting it pass. Breathe out slowly through your nose, wait a moment, and let the next breath arrive on its own. It gets easier with practice. There’s more on sighing in why do I sigh so much?.

Is air hunger a sign of anxiety?

Often, yes, especially when it comes and goes with stress, eases when you’re distracted, and arrives with other anxious feelings like a racing heart or a tight chest. Many people notice it’s worse when they’re sitting still and thinking about it, and better when they’re busy or moving.

If the breathing gets fast and you start to tingle, how to stop hyperventilating has the next step. For daily practice, an even 5 in and 5 out for 10 minutes on calm days helps the slower rhythm feel familiar. In Breathform, choose the rounds before you start, and the clock is its job, not yours.

When is shortness of breath not anxiety?

Breathlessness has many causes, and anxiety is only one. See a doctor if it’s sudden or severe, gets worse when you’re resting or comes on mainly with effort rather than worry, if it comes with chest pain, a wheeze, a cough or a fever, or if you have a heart or lung condition. Once you’ve been told it’s anxiety, the breaths on this page are a good place to start, and breathing exercises for anxiety has more.

• Boulding et al., 2016: Review: dysfunctional breathing describes breathlessness and other symptoms from chronic changes in breathing pattern, without (or out of proportion to) heart or lung disease; patterns include hyperventilation syndrome, periodic deep sighing and thoracic dominant breathing.
• Thomas et al., 2005: In a UK general practice postal survey of adults aged 16 to 65 without asthma, 8% had screening scores suggesting dysfunctional breathing (14% of women, 2% of men), against 29% of adults with asthma.
• Magnon et al., 2021: In 47 younger and older adults, anxiety was lower after one five-minute slow-breathing session, though the study had no comparison group.
• Vlemincx and Luminet, 2020: Two experiments showed that sighs can become learned behaviours through operant learning, which may contribute to maladaptive sighing and breathing complaints.

Questions people ask

Why does anxiety cause shortness of breath?

Anxiety switches on your body’s threat response, which speeds up your breathing and tenses the muscles around your chest. You start breathing a little more than you need, often high in the chest. That shifts your blood chemistry slightly and makes each breath feel less satisfying. Then you notice it, worry about it, and the loop tightens.

How long does air hunger from anxiety last?

It varies. For some people it’s a few minutes in a stressful moment. For others it comes and goes for days or weeks during an anxious stretch. Checking your breathing often tends to keep it going, so once you’ve done a few minutes of slow breathing, turn your attention to something else and let your body breathe on its own.

Can air hunger happen when I don’t feel anxious?

Yes. Over-breathing can carry on as a habit after a stressful time, an illness or a chest infection, even when you feel calm. That pattern is sometimes called dysfunctional breathing. Respiratory physiotherapists teach breathing retraining for it, so it’s worth asking your GP about a referral if it keeps coming back.

Should I try to take a deep breath?

It’s better not to chase one. A deep breath taken on top of a chest that’s already fairly full often feels blocked, which makes you try harder. Breathe out slowly first, then let a small breath come in through your nose. The satisfying breath usually turns up on its own once you stop reaching for it.
