Breathwork
Breathwork is not the same as mindfulness. Mindfulness involves passive observation of the breath, whereas breathwork requires you to actively change the way you breathe.
Breathwork includes ensuring you breath with your diaphragm, rather than the movement of your chest. It will fill your lungs with more air while also slowing the pace of your breathing.
