Deep Breathing Exercises & Techniques

Deep breathing exercises are widely recognized for their potential benefits in various health conditions, ranging from respiratory issues to stress management. This article explores different deep breathing techniques, their applications, and the outcomes observed in various studies.

Diaphragmatic Breathing for Asthma

A study on diaphragmatic breathing without the aid of a physical corset demonstrated significant benefits for asthmatic patients. Participants who practiced deep diaphragmatic breathing showed a notable reduction in medication use and asthmatic symptoms. Additionally, there was a nearly 300% increase in time spent on physical activities. However, adherence to the technique post-intervention was a challenge, with many patients reverting to previous medication levels and sedentary habits1.

Postoperative Pulmonary Function

Deep breathing exercises have been shown to reduce atelectasis and improve pulmonary function following coronary artery bypass graft (CABG) surgery. Patients who performed deep-breathing exercises had significantly smaller atelectatic areas and better pulmonary function compared to those who did not perform the exercises. The exercises also resulted in a smaller reduction in forced vital capacity (FVC) and forced expiratory volume in one second (FEV1)2.

Slow Deep Breathing and Lung Capacity

A preliminary study evaluated the immediate effects of slow deep breathing exercises paired with sustained maximal inspiration (SMI) using a volume-oriented incentive spirometry (VIS) device. The results indicated significant improvements in diffusing lung capacity (DLC) and alveolar volume (VA) when the SMI technique was included. Both techniques also increased total lung capacity (TLC), with the combination of SDBE/VIS and SMI showing superior results3.

Benefits for Smokers

Deep breathing exercises have been found to improve lung functions in healthy smokers. A pilot study revealed significant improvements in vital capacity, inspiratory capacity, tidal volume, expiratory reserve volume, forced expiratory volume, and forced vital capacity after two weeks of intervention4. Another study confirmed these findings, showing that deep breathing exercises significantly enhanced lung volumes and capacities among smokers over a six-week period7.

Cardiac Surgery Recovery

The effectiveness of deep breathing exercises post-cardiac surgery has been explored in several studies. One study found no significant differences in lung function or quality of life between patients performing home-based deep breathing exercises and those who did not, two months post-surgery5. However, another study indicated that performing 30 deep breaths hourly with positive expiratory pressure significantly improved oxygenation compared to performing 10 deep breaths hourly6.

Techniques Comparison

A comparison of three deep breathing techniques post-CABG surgery—using a blow bottle device, an inspiratory resistance-positive expiratory pressure mask (IR-PEP), and no mechanical device—showed no major differences in pulmonary function among the groups. However, the blow bottle technique resulted in a significantly smaller reduction in total lung capacity compared to the deep breathing group without a device8.

Pranayama for Cancer Patients

Pranayama, a form of deep breathing exercise, has been shown to improve sleep quality and reduce fatigue in women undergoing radiation therapy for breast cancer. The study highlighted that pranayama is easy to learn, can be performed anywhere, and does not require any equipment, making it a convenient option for patients9.

Chronic Tension-Type Headache

A randomized control trial assessed the effectiveness of progressive muscle relaxation and deep breathing exercises on pain, disability, and sleep quality among patients with chronic tension-type headache. The intervention group reported less pain severity, reduced disability, and better sleep quality after 12 weeks10.

Conclusion

Deep breathing exercises offer a range of benefits across different health conditions, from improving lung function in smokers and postoperative patients to enhancing sleep quality and reducing fatigue in cancer patients. The effectiveness of these techniques can vary based on the specific method and patient adherence, highlighting the need for tailored encouragement and consistent practice.
