You do not fall into the mode of life stress. You can use the breath to relax rather than stress, your mind and your body. Yoga helps you to their natural state, your body and your mind: learn relaxation.
Deep breathing is both calming and stimulating. The energy you feel is not breathing slowly for a few minutes of nervousness or hyperactivity, but the calm, steady energy we all need. Slow and steady and quiet breathing gives a message to your nervous system: Be calm.
Entire books have been written on yoga breathing. Here’s a 5 minute Breath Break. (Read the instructions several times before you try to practice.)
First Sit with your spine as straight as possible. Use a chair if necessary but do not break into it. Feet flat on the ground, the knee directly over the center of your feet. Use a book or pillow under your feet, if they do not rest comfortably on the floor. Hands on the upper legs.
Second Close your eyes and let sit quietly behind closed eyelids.
Think about your third rib to the front, rear and sides of your body. Your lungs are behind the ribs.
4th Feel your lungs fill, the ribs expand outwards and upwards. Feel your lungs emptying, the coast back down and not push you on the breath.
5e first time you do, work for 2-3 minutes, then do it for a maximum of 50-10 minutes. Initially, reserve a period of at least once a day to do so. When you learn how you feel about it, you want to get it at other times.
Like a stressful situation goes into the next challenge, relax for a few minutes every day gradually carries over the rest of your life and activities.
