From “breathwork recipes” to breathing techniques, many and are recommending breathwork to reduce stress.

But breathwork is not new. Rather it is the latest in a long history of breathing techniques such as from India and from China. Such practices have been used for thousands of years to promote a healthy mind and body.

The benefits can be immediate and obvious. Try taking a deep breath in through your nose and exhaling slowly. Do you feel a little calmer?

So, what’s the difference between the breathing we do to keep us alive and breathwork?

Breathwork is about control

Breathwork is as . While the latter focus on observing the breath, breathwork is about .

Normally, breathing happens automatically via messages from the brain, outside our conscious control. But we can control our breath, by directing the movement of our diaphragm and mouth.

is a large muscle that separates our thoracic (chest) and abdominal (belly) cavities. When the diaphragm contracts, it expands the thoracic cavity and pulls air into the lungs.

Controlling how deep, how often, how fast and through what (nose or mouth) we inhale is the crux of breathwork, from to the .

Breathwork can calm or excite

Even small bits of breathwork can have physical and mental health benefits and to avoid burnout.

Calming breathwork includes diaphragmatic (belly) breathing, slow breathing, pausing between breaths, and specifically slowing down the exhale.

In diaphragmatic breathing, you consciously contract your diaphragm down into your abdomen to inhale. This pushes your belly outwards and makes your breathing deeper and slower.

You can also by doing:

• (count to four for each of four steps: breathe in, hold, breathe out, hold), or

• (controlled slow breathing of five or six breaths per minute), or

• (close the left nostril and breathe in slowly through the right nostril, then close the right nostril and breathe out slowly through the left nostril, then repeat the opposite way).

You can slow down the exhalation specifically by counting, humming or pursing your lips as you breathe out.

In contrast to these calming breathing practices, energising fast-paced breathwork increases arousal. For example, (breathe in and out quickly, but not deeply, through your nose in a consistent rhythm) and (breathe out through your mouth, stick your tongue out and make a strong “haa” sound).

What is happening in the body?

Deep and slow breathing, especially with a long exhale, is the best way to . The vagus nerves pass through the diaphragm and are the main nerves of the parasympathetic nervous system.

Simulating the vagus nerves calms our sympathetic nervous system (fight or flight) stress response. This improves mood, lowers the stress hormone and helps to regulate emotions and responses. It also promotes more , .

Taking deep, diaphragmatic breaths also has . This improves blood flow, lung function and exercise performance, increases oxygen in the body, and strengthens the diaphragm.

reduces heart rate and blood pressure and increases heart rate variability (normal variation in ). These are linked to better heart health.

Taking shallow, quick, rhythmic breaths in and out through your nose stimulates the sympathetic nervous system. Short-term, controlled activation of the stress response is healthy and .

Breathing in through the nose

We are designed to , not our mouth. Inside our nose are lots of . These warm and humidify the air we breathe and filter out germs and toxins.

We want the air that reaches our airways and lungs to be clean and moist. Cold and dry air is irritating to our nose and throat, and we don’t want germs to get into the body.

increases parasympathetic activity and releases nitric oxide, which improves airway dilation and lowers blood pressure.

Consistently breathing through our mouth . It can lead to and reaching the lungs, snoring, sleep apnoea, and including cavities and jaw joint problems.

A free workout

– even short sessions at home – can reduce stress, anxiety and depression in the general population and among those with clinical depression or anxiety. Research on breathwork in (PTSD) is also promising.

Diaphragmatic breathing to improve lung function and strengthen the diaphragm can improve breathing and exercise intolerance in , and . It can also and (an imbalance of more free radicals and/or less antioxidants, which can damage cells) after exercise.

A mind-body connection you can access any time

If you feel stressed or anxious, you might subconsciously , but this can make you feel more anxious. Deep diaphragmatic breaths through your nose and focusing on strong exhalations can help break this cycle and bring calm and mental clarity.

Just of breathwork can improve your physical and mental health and wellbeing. Daily deep breathing exercises reduce blood pressure and stress, which is important since .

Bottom line: any conscious control of your breath throughout the day is positive.

So, next time you are waiting in a line, at traffic lights or for the kettle to boil, take a moment to focus on your breath. Breathe deeply into your belly through your nose, exhale slowly, and enjoy the benefits.
