Continuous breathing is a wonderful way to deal with emotional distress or mental confusion, a lovely way to refresh the body and mind.
To begin, lie down on your back, with a blanket over you if you need it for warmth. Put a pillow under your knees in order to relax your low back, or bend your legs and prop your knees together. Put your hands on your chest or belly. Close your eyes, and your mouth.
Begin to breathe. Breathe without pauses. As soon as you get to the top of the inhale, begin the exhale. As soon as you get to the bottom of the exhale, begin the inhale.
It doesn't matter whether you breathe more with the chest or with the belly. Breathe however is comfortable for you. Change postition if you need to. Straighten your legs or roll onto your side. But keep breathing. Change from breathing through your nose to breathing through your mouth, if that feels better.
Feelings may come up. Some might be scary. The best way to deal with scary feelings is to keep breathing. The best way out is through.
Thoughts may come up. Your mind may become clear, and you may find this is a good time to think about things.
You may experience tingling in some part of your body. It might be a part where you're tense or holding on or resisting. Again, the best way to deal with it is to keep breathing.
Breathe for at least forty minutes. You can breathe longer than that if you want to. It takes that long for most people to reach a "breath release," when the breathing becomes effortless and refreshing.
I've done several thousand breathing sessions over the last 25 years, and believe me, it won't hurt you. And if you don't stop breathing, it will help you.
