Your nose is directly linked to your brain and nervous system. For thousands of years the Indian yogis believe that many diseases are connected to disturbed nasal breathing.
Breathing in through your left nostril will access the right “feeling” hemisphere of your brain, and breathing in through your right nostril, will access the left “thinking” hemisphere of your brain. Consciously alternating your breath between either nostril will allow you to activate and access your whole brain.
1. It activates the parasympathetic nervous system and reduces blood pressure.
2. It enhances respiratory functions: increases respiratory strength and endurance.
3. It improves attention and fine-motor coordination/performance.
So this is good for our hearts; good for our lungs; and good for our heads.

5.Exhale through your right nostril
6.Now, inhale through right nostril
8.Use thumb to close of right nostril
9.Breathe out through left nostril
10.This is one round. Start slowly with 1 or 2 rounds and gradually increase.
