Controlled Breathing – Official Medicine on Controlled Breathing
Controlled breathing is a practice where a person consciously regulates their breathing process by changing the rhythm, frequency, depth, and duration of inhales and exhales.
Breathing and Its Impact on the Immune System: Wim Hof’s Method
Conducted by: Dr. Matthijs Kox and Professor Peter Pickkers.
Location: Radboud University, Nijmegen, Netherlands.
Year: 2014.
Method: Participants trained in Wim Hof’s breathing technique were injected with an endotoxin (a bacterial lipopolysaccharide) to induce an inflammatory reaction. The control group did not use any breathing techniques.
Results: The Wim Hof group showed a 50% reduction in inflammatory markers (cytokines like IL-6) compared to the control group. Participants also reported reduced symptoms such as fever and headaches.
Study on the Effect of Pranayama (Yoga Breathing) on Depression
Conducted by: Dr. Patangali Kunti and his team.
Location: Institute of Mental Health, Bangalore, India.
Year: 2021.
Method: 50 patients with moderate depression practiced the technique of pranayama (Ujjayi) daily for 15 minutes over 12 weeks.
Results: Participants showed a 25% reduction in depression symptoms according to the Beck Depression Inventory, along with improved overall well-being, increased serotonin levels, and better sleep quality.
Buteyko Method and Its Impact on Asthma
Conducted by: Researchers from the Australian Institute of Asthma under Professor Simon Dors.
Location: Australia.
Year: 2018.
Method: 90 asthma patients were divided into two groups: one practiced the Buteyko Breathing Method, while the other received standard medication.
Results: After 3 months, the Buteyko group experienced a 50% reduction in asthma symptoms, a 40% reduction in the need for bronchodilators, and improved quality of life. This method helps reduce hyperventilation and normalize blood CO2 levels, preventing bronchial spasms.
Breathing’s Impact on Inflammation of the Airways in Asthma Patients
Conducted by: Dr. Matthijs Kox and Professor Peter Pickkers.
Location: Radboud University, Nijmegen, Netherlands.
Year: 2021.
Method: Participants practiced Wim Hof’s breathing technique (intense breathing with holds and cold therapy) for 4 weeks.
Results: Asthma patients showed a reduction in inflammatory cytokines (IL-6 and TNF-α) and symptom improvement, linked to enhanced autonomic nervous system activation and a stronger anti-inflammatory response.
Coherent Breathing for Easing Asthma and Allergy Symptoms
Conducted by: Dr. David Otto and his team from New York University.
Location: New York, USA.
Year: 2022.
Method: 50 allergy and asthma patients practiced coherent breathing (slow, rhythmic, and shallow breathing at a rate of 5-6 breaths per minute) daily for 15 minutes over 2 months.
Results: The study showed improvements in respiratory function and a reduction in anxiety. Controlled breathing helped reduce asthma attacks and enhanced quality of life.
Diaphragmatic Breathing in Chronic Asthma
Conducted by: Dr. Peter Lucas and colleagues from the University of Southampton.
Location: United Kingdom.
Year: 2020.
Method: 120 adults with chronic asthma practiced diaphragmatic breathing (15 minutes daily) for 8 weeks.
Results: There was a 10-15% improvement in lung function (measured by FEV1), along with fewer nighttime asthma attacks and reduced shortness of breath. Diaphragmatic breathing facilitates more efficient ventilation and reduces the strain on respiratory muscles.
Study on the impact of slow breathing on reducing stress and anxiety
Conducted by: Dr. Lucio Annicchiarico and colleagues.
Where: Faculty of Medicine, University of Sapienza, Rome, Italy.
When: 2020.
Method: 40 healthy adult volunteers participated and were divided into two groups. The first group practiced slow breathing (6 breaths per minute) for 10 minutes daily. The second group used normal breathing.
Results: Participants in the first group showed a significant reduction in cortisol levels (by 20%) and improved heart rate variability (HRV), indicating better adaptation to stress. Anxiety levels were also reduced (15% decrease in the Hamilton anxiety scale).
Use of the 4-7-8 breathing technique to improve sleep
Conducted by: Researchers from Harvard Medical School under Dr. Andrew Weil.
Where: Harvard Medical School, Boston, USA.
When: 2018.
Method: 100 participants with sleep issues were divided into two groups. One group practiced the 4-7-8 breathing technique before sleep for 8 weeks, while the other continued their usual pre-sleep routines.
Results: Participants practicing 4-7-8 breathing fell asleep 25% faster on average, and their sleep quality, measured by the Pittsburgh Sleep Quality Index (PSQI), improved by 17%.
Diaphragmatic Breathing and Reduction of Blood Pressure in Hypertension Patients
Conducted by: Dr. Thomas Reiber and his team from Munich University.
Conducted by: Dr. Thomas Reiber and his team from Munich University.
Year: 2019.
Method: 60 hypertension patients practiced diaphragmatic breathing for 10 minutes daily for 6 weeks.
Results: A reduction in systolic blood pressure by 9 mmHg and diastolic by 6 mmHg was observed. There was also an improvement in autonomic nervous system function and stress reduction.
Impact of Yogic Breathing on Allergic Rhinitis
Conducted by: Dr. Rohit Sharma and colleagues.
Location: Allergy and Immunology Institute, New Delhi, India.
Year: 2019.
Method: 60 patients with allergic rhinitis practiced pranayama (alternate nostril breathing, “anuloma-viloma”) daily for 10 minutes over 6 weeks.
Results: Participants showed reduced nasal congestion and sneezing frequency, as well as decreased mucosal swelling. This was linked to improved airflow and activation of the parasympathetic nervous system, reducing inflammation.
Coherent Breathing to Improve Cognitive Function in Alzheimer’s Disease
Conducted by: Dr. Ronald Harper and his team.
Location: University of California, Los Angeles (UCLA), USA.
Year: 2019.
Method: 45 patients with mild cognitive impairments and early-stage Alzheimer’s disease practiced coherent breathing (5-6 breaths per minute) for 15 minutes daily over 12 weeks.
Results: Participants showed improvements in cognitive function (evaluated using the Mini-Mental State Examination), mood, and a reduction in anxiety levels. Additionally, there was improved circulation in the hippocampus, an area crucial for memory and learning.
Study on the Effect of Slow Breathing on Cognitive Function in Older Adults
Conducted by: Dr. Sandra Bond Chapman and her team.
Location: Brain Research Center, University of Texas at Dallas, USA.
Year: 2020.
Method: 108 older adults (aged 65+) with early signs of cognitive decline practiced slow breathing (6 breaths per minute) for 20 minutes a day, 5 times a week for 8 weeks.
Results: Significant improvements were observed in memory and attention tests. There was also an increase in heart rate variability (HRV), indicating better parasympathetic nervous system function and reduced stress. The researchers noted that improved blood circulation and oxygen delivery to the brain help slow down neurodegenerative processes.
