Breathwork: slow breathing, sighing, holds, stress outcomes, and safety
On this page
Breathwork means deliberately changing aspects of breathing, such as pace or the relative length of an inhalation and exhalation. Gentle breathing for stress is one example. NHS guidance emphasizes comfort and an unforced breath; a more intense exercise is a different exposure.[1]
Similar names can describe different breathing patterns
| Pattern | What distinguishes it |
|---|---|
| Gentle slow breathing | A comfortable, regular breath without forcing depth.[1] |
| Cyclic sighing | The studied exercise emphasizes a longer exhalation.[3] |
| Box breathing | The studied exercise includes inhalation, holding, exhalation and another hold of equal duration.[3] |
| Cyclic hyperventilation with retention | The studied exercise combines faster breathing with breath retention; it is distinct from gentle breathing.[3] |
Deeper and faster breathing can reduce carbon dioxide
Hyperventilation means overbreathing. Excess ventilation can lower blood carbon dioxide and produce dizziness, tingling, muscle spasms or a sense of breathlessness. These effects should not be interpreted automatically as detoxification, emotional release or evidence of a successful treatment.[4]
Rapid breathing can have emotional or medical causes. MedlinePlus includes infection, heart or lung problems and metabolic illness among possibilities. New, unexplained or severe breathing symptoms need assessment; attributing them to stress and continuing a protocol can miss the cause.[4]
A basic stress exercise has a different aim from a challenge
The NHS example allows sitting, standing or lying comfortably. Counting is optional, and the breath should flow gently without forcing it. Its purpose is a calming routine. It does not require maximal lung filling, competitive breath retention or a progressively more intense sensation.[1]
Water changes the stakes of breath holding
CDC drowning-prevention guidance warns against hyperventilating before swimming and against prolonged breath holding. Loss of consciousness in water can lead to drowning. A land-based stress study supplies no safety evidence for underwater challenges, breath-holding competitions or combining a breathing exercise with a plunge.[5]
Medical breathing training is usually part of a broader program
Pulmonary rehabilitation may include pursed-lip breathing or other techniques alongside exercise, education and disease management. Clinicians adapt the plan after assessing lung function and activity capacity. This is different from a stand-alone wellness breathwork challenge. Benefits of a comprehensive rehabilitation program cannot be assigned automatically to one breathing exercise or to forceful hyperventilation and breath holding.[6]
Evidence & uncertainty
Selected trials suggest improvements in self-reported stress or mood. The evidence is limited by small studies, bias and inadequate longer-term follow-up. These findings do not establish that every breathing protocol treats a disorder or improves long-term health. Fast and slow practices cannot be treated as one proven intervention.[2]

A promising average stress effect is not a percentage cure
A 2023 meta-analysis pooled 12 randomized studies with 785 participants for self-reported stress. Its standardized effect was −0.35, with a 95% confidence interval of −0.55 to −0.14, favoring breathwork over control conditions. This is a difference in standardized scores, not a 35% reduction in disease risk.[2]
Ten of those studies mainly used slower breathing. Studies differed in populations, delivery and comparison groups, and every study had bias concerns. There were too few follow-up data for a pooled estimate of lasting stress benefit. A short-term improvement therefore leaves important questions about durability and clinical use open.[2]
What the widely discussed sighing trial actually compared
A 2023 remote randomized study compared three breathing exercises with an equal period of mindfulness meditation: five minutes daily over one month. The authors reported greater improvement in positive mood and a greater reduction in respiratory rate with breathwork, particularly exhalation-focused sighing.[3]
That comparison is narrower than “breathing is better than meditation.” It tested brief exercises, specific measures and a short follow-up. A change in breathing rate or reported mood is not evidence of preventing cardiovascular disease, curing anxiety disorders or extending life.[3]
