Breathwork is the practice of conscious breathing.  It brings the body into present moment awareness and helps transition from shallow breathing to deep, parasympathetic activating breaths.

Activating the parasympathetic nervous system calms the mind and leads to deep relaxation. Just five minutes of breathwork is all it takes to change your mood and invoke more peace.

Let’s try a simple breathwork practice: 4-2-6 breathing.  

Get into a comfortable seated position. 
Draw your attention inward.
Releasing all tension in your body, inhale for a count of 4.
Pause for 2. 
Exhale to the count of 6.
Pause for 2. 

Continue this cycle of breathing for 5 minutes.
If 4-2-6 is too strenuous, try inhaling for 2, pausing for 1, and exhaling for 4 (pausing for 1 at the end of the exhale).
