I found this very interesting and found it definitely worth sharing :
Yogi Vishvketu teaches the detoxifying and purifying Kapalabhati Kriya. This cleansing breathwork technique removes phlegm from the respiratory system, refreshes the oxygenation of the base of the lungs, and promotes healing.
This video is 14minutes long. I recommend finding a quiet moment in your day without distractions.
Just in time for cold and flu season (!)
