Breathing is normally something we don’t consider much. This is due to it being an automatic involuntary function, but does it make any difference to breathe through our nose or mouth?
When breathing through our nose the air is humidified increasing the amount of moisture to the air. However with mouth breathing there is a great increase of dehydration of the respiratory tract which increases the risk of shallow breaths, inflammation and increased risk.
Another benefit of natal breathing is the release of nitric oxide this neurotransmitter sterilises the incoming air but also splints open the airways to exchange oxygen exchange into the blood.
Breathing through your nose also helps optimise your diaphragm efficiency. This can allow for greater engagement of your core and this improves posture and stability. However mouth breathing increases the use of accessory neck muscle which can cause a rounded neck and back posture leading to tightness and discomfort.
Nasal breathing can help regulate our heart rate, this assists with activating our parasympathetic nervous system which improves stress levels, sleeping efficiency and recovery post-exercise.
Efficiency with nasal breathing during aerobic exercise has proven to decrease respiratory rate which ultimately leads to an increase in oxygen uptake and better control over the body's pH. In mouth breathing if carbon dioxide is lost too quickly (increase of respiratory rate) oxygen absorption is decreased, which can result in dizziness or even fainting (hyperventilation).
This is only some of many great benefits of nasal breathing. So remember to take time everyday to practice conscious nasal breathing!
