As the only automatic bodily function we can readily control the breath serves as a primary link between our mind and body. For this reason many high performance athletes and experienced meditators will train their breath extensively.
The myriad of benefits are readily available to you too!
Taking some deep breaths positively alters your states of mind, calms your nervous system, oxygenates your blood, energises your brain and rids your body of mental and physical waste.
So whenever you feel overwhelmed, drowsy or anxious.
Stop.
Take some deep breaths.
Pay attention to all the positive sensations as they sweep over your body.
Then when you are ready… carry on.
