Hello friend,
Good to see that you are interested to learn the technique of good breathing.
This can be done within a time period of 10 minutes.
1. Get Ready (2 minutes) Make the room dark, or darker. Lie down flat on your back, or sit against a wall. Use a pillow for comfort. Make sure no part of your body is strained or supporting weight. Close your eyes. Just pay attention to your breathing for a minute or two. Don't try to change it, just notice how it feels. Imagine the fresh blood flowing through your body. Listen to your surroundings.
2. Stage I (2 minutes) Practice breathing in and out of your nose. Exhaling through the mouth is okay for quick relaxation, but for normal breathing, in and out the nose is best. Take long breaths, not deep breaths. Try not to force it, you shouldn't hear your breath coming in or out. You're drawing slow breaths, not gulping it or blowing it out. Feel the rhythm of your breathing.
3. Stage II (3 minutes) Good breathing is done through the lower torso, rather than the upper torso. Each breath should expand your belly, your lower back and ribs. Relax your shoulders and try not to breathe with your chest. Put your hands on your abdomen and feel them rise and fall. If it's not working, push down gently with your hands for a few breaths and let go. Your abdomen should start to move more freely. Relax your face, your neck, your cheeks, your jaw, your temples, even your tongue.
4. Stage III (3 minutes) Feel the good air entering your lungs and feel the stale air leaving your body. "In with the good, out with the bad" is definitely true here. Make your exhale as long as your inhale to make sure all the bad air is gone. Remember, long slow breaths. Most people take 12-16 breaths per minute. Ideally, it should be 8-10. Now try to make your exhale a little longer than your inhale for a while. Pause after your exhale without taking a breath. Focus on the stillness and on not forcing an inhale. Your body will breathe when it needs to.
5. Wake Up!!!
This type of practice will give you more benefits than what you have described.
With best wishes,
DR C. J. Varghese

1.Breathing is an expression of energy, and Yoga techniques help us to become aware of our breathing,concentrate on it, control it and synchronize it. This helps us to breathe in a more relaxed and natural manner.
2. The respiratory movement represent only a small portion of the activities of this life force, Yogis realized that there existed a close relationship between the breathing process and the mind,so they developed breathing techniques.
3. the nostrils are related to various systems (sympathetic,parasympathetic).
4. as the mind directly affects all the functions of the body, most diseases are believed to have a mental origin. Here lies the value of Pranayam (bio-energy), or the regulation of the breathing process by which we are able to control all mental activity and thus master our body and mind.
5. You can consult a good Ayurveda/Yogic Trainer-teacher for further in-depth analysis of the same.
