One common exercise that everyone can practice is called ‘Pursed Lip’ breathing. To do this, we first have to sit straight, then take a slow deep breath through the nose.
Next, we must purse our lips so they are almost in touching position (much like a kissing/whistling face) and then breath out through it. The exhalation should be longer than the inhalation phase.
Pursed lip exercise is particularly beneficial for physically less active people, especially those who may not be frequently exercising their breathing muscles.
Another exercise is known as ‘Belly Breathing.’ According to the US COPD foundation, this follows some simple steps, i.e. relaxing shoulders and sitting back or lying down, one hand on the belly and one on the chest.
Inhale through your nose for two seconds and feel the stomach move out. The stomach should move more than the chest.
Breathe out for two seconds through pursed lips while pressing on the abdomen; repeat.
