I tried this when I just woke up in the morning, feeling at first a bit tired and restless in my body at the same time, and with a headache... the humming gave me a resting feeling with every set, but also feeling more awake and less restless, and the headache is now almost gone , I think I really needed this one today. I want to thank you, because of your breathing techniques I now do on a daily base... I also started meditating, and both of these are really helping my state of mind, thank you thank you thank you 🙏♥️
