Deep breathing has often been underestimated as a method for alleviating stress and anxiety. However, mastering the art of deep breathing can significantly impact your mental well-being. In this comprehensive guide, we’ll explore the science behind deep breathing and present various evidence-based techniques, including the physiological sigh, that you can use to combat stress and anxiety.
The Science Behind Deep Breathing
Deep breathing stimulates the parasympathetic nervous system, responsible for relaxation. Studies have shown that engaging in deep breathing can reduce cortisol levels, effectively mitigating feelings of stress and anxiety.
The Importance of Diaphragmatic Breathing
For maximum effect, breathing from the diaphragm is essential. This form of breathing allows better oxygen exchange and helps stabilize blood pressure, providing a sense of inner calm.
Proven Deep Breathing Techniques and How to Perform Them
The 4-7-8 Technique
This technique involves inhaling through the nose for 4 seconds, holding the breath for 7 seconds, and then exhaling through the mouth for 8 seconds. This technique is based on an ancient yogic technique called pranayama, which helps with breath control.
- Inhale through your nose quietly for 4 seconds.
- Hold your breath for a count of 7 seconds.
- Exhale completely through your mouth for 8 seconds.
This technique originates from the ancient yogic technique of pranayama, which focused on breath control.
Also known as four-square breathing, this technique involves inhaling, holding the breath, exhaling, and holding the breath again, all for four seconds each. This is a common technique used by Navy SEALs to calm nerves in high-stress situations.
- Inhale through your nose for 4 seconds.
- Hold your breath for 4 seconds.
- Exhale through your mouth for 4 seconds.
- Hold your breath again for 4 seconds.
Progressive Muscle Relaxation and Breath Control
This involves deep diaphragmatic breathing coupled with progressive muscle relaxation. Inhale deeply while tensing a muscle group (e.g., your fists or your biceps), and then exhale while releasing the tension.
- Take a deep diaphragmatic breath while tensing a muscle group (e.g., your fists).
- Exhale slowly while releasing the tension.
The Physiological Sigh
The Physiological Sigh is a natural breathing pattern involving two quick, successive inhales followed by a longer, slower exhale. This unique pattern has been extensively studied for its potential benefits in reducing stress and anxiety. Research shows that this breathing pattern naturally occurs in humans during sleep, usually when the body is seeking to relieve an excess of carbon dioxide.
The Science Behind the Physiological Sigh
A noteworthy study by Stanford Medicine investigated the neural circuits in the brain that control the Physiological Sigh. The twin inhales effectively increase the volume of the lungs, helping to distribute air evenly and facilitating a more efficient release of carbon dioxide during the exhale.
Moreover, another study published in the “Journal of Applied Physiology” highlighted that the Physiological Sigh can be intentionally employed to decrease levels of stress and anxiety. It showed that the longer, slower exhale that follows the quick inhales activates the body’s relaxation response, signaling the brain to release neurochemicals that induce feelings of relaxation and tranquility.
- Quickly inhale through your nose.
- Immediately follow with a second, fuller inhale.
- Exhale slowly and completely
The idea is to fully expand your lungs during the double inhale, thereby activating the alveoli—tiny air sacs in your lungs responsible for gas exchange. This full expansion is what makes the subsequent slow exhale so effective in eliminating a high percentage of carbon dioxide from your body.
The Role of Mindfulness in Deep Breathing
Mindfulness takes your deep breathing techniques to the next level. By focusing your mind on your breath, you not only perfect your technique but also gain improved control over your mind’s chatter. Mindfulness-based stress reduction programs often incorporate deep breathing as a fundamental component.
Making Deep Breathing a Habit
Consistency is key. Make deep breathing part of your daily routine by setting aside at least five minutes a day for this practice. Creating a calm environment can also encourage more effective deep breathing.
A Word of Caution
While deep breathing is generally safe, it may not be suitable for everyone. People with respiratory issues such as asthma or COPD should consult their healthcare provider before beginning any new breathing exercises.
Deep breathing is an underrated but incredibly effective technique for reducing stress and anxiety. The beauty of these techniques lies in their simplicity and efficacy. They require no special equipment, can be done anywhere, and offer immediate relief from symptoms of stress and anxiety.
