The one thing that you do automatically, without thinking, is breathing. Mindful breathing is when we take manual control of our breath.
It follows like this:
INHALE (for a count of 5)…. HOLD (for a count of 5), EXHALE (for a count of 5) repeat this 5 times
This exercise should take around half a minute to perform. Try to breath in, past your chest and into your tummy, and solely focus on this one, vitally important task.
