The increase of Oxygen through deep breathing increases your vitality by activating the cell production! It releases tension and toxins, it helps to prevent and release back pain and insomnia among other health issues. It relaxes the nerve system, brings clarity into your mind and opens the channels for better concentration.
I took breathing into my teaching, because I noticed that many people do not get enough oxygen into there body.
Take the chance and come for a trial, once is better than never. Once a week will be a great step into more comfort in your life.
