Beware of long term breath following exercises.
They can be wonderful for some and harmful for others. If your breathing is out of balance and you follow it, then what? I use a scientifically proven biofeedback device to measure blood carbon dioxide saturation in real time and learned that with some people even the slightest attention to the breathing can sometimes cause the inhale to develop a subtle and almost undetectable to the eye or inner sensing, erratic breathing sequencing during the exercise and that helps to support the pre-existing breathing pattern disorder. What is perceived as relaxation may be better or worse then it was before but along with a long term tendency to cause or exacerbate what I call UDB. If you've tried them and felt they did not work for you, you may have UDB.
