What happens when you breathe deeply

Deep breathing, or diaphragmatic breathing, is a skill that many of us have lost. To know what it’s like to really breathe deeply, take a minute out and observe a baby and what happens when they breathe. Their whole belly rises and falls with each breath, rather than just the chest. Now have a look at how most adults breathe – you rarely see the belly moving much at all, and if it does, it’s usually just the upper portions, rather than the whole abdomen. But this is a skill that could be highly important to get back in touch with.

Breathe shallow…

As we’ve aged in this modern world, we’ve lost the instinct to breathe deeply. But there are many benefits from taking in deep breaths, and conversely, shallow breathing can be doing us harm. Shallow breathing can create a cycle of stress in our bodies, where breathing shallowly makes us feel stressed, and then feeling stressed makes us breathe more shallowly.

And over the long term shallow breathing and chronic stress can have an impact on our immune systems. It can lead to lower levels of white blood cells in our system, which help our body defend itself from invading bacteria and viruses. This can then set up a situation where we’re at higher risk of catching acute illnesses like the common cold, flu, or stomach bugs.

Shallow breathing uses the accessory breathing muscles of the chest, neck and shoulders, rather than the diaphragm, which can in turn lead to tighter muscles through this area, causing neck pain, headaches, and a greater risk of injuries.

And breathe deep…

Breathing deeply on the other hand has many health promoting benefits. It can lower your blood pressure, reduce your heart rate, decrease stress by lowering cortisol levels, and relaxes your muscles.

And you can see the benefits immediately. Taking a few minutes out of your day to focus on breathing deeply will have you feeling calmer instantly. So go on, breathe!
