Basic science of Deep Breathing

Before we dive into basic science of deep breathing or all about deep breathing meditation or deep breathing exercises, I wish to ask you question, are you seeing any miracle in your day to day to life?

Most of you would give a simple answer: No.

Breathe is miracle!  The event that happens 20,000 to 22,000 times per day automatically, We pay very little attention or not aware about this event. We are not conscious about our breathing.

What is breathe?

Oh! You gotta a question? Right? The air exchange in human body’s lungs to provide life to humans. This would be most short definition of breathe. Breathing is inspiration and expiration of the air into the human body to provide oxyzone and take out carbon dioxide.

Science of breathing

What is science of breathing? Or how we take breathe. There are two major event happen in breathing. Inspiration or inhalation and expiration or exhalation. Let us understand the pathway or journey of the air into the respiratory system of human body.

  • Journey of the air starts from the nose/nostrils.
  • Air enters into the pharynx (throat).
  • After pharynx it enters into the larynx(Voice box).
  • After this it enters into trachea.
  • Goes into the two branches of lungs called as left and right bronchus.
  • After bronchus it further divides into tiny bronchioles.
  • Further divides into very tiny very important part where actual gas exchange happens called as alveoli.

On an average, adult human takes 7 to 8 liters of air per minute that accumulates to 11,000 liters of air in a day. Out of this 20% of O2 we take into inhale and 15% of we take out during exhale, so we take about 560 liter of the pure oxygen in a day.

 The composition or air when we inhale and exhale.

 

Gas Inhale Exhale
Nitrogen 78.62% 78.04%
Oxyzen 20.84% 16%
CO2 0.04% 4%-5%
Argon 0.96% 0.5% to 1%
Water Vapour 0.5% 0.5%

It is clear from the table that oxygen is consumed and CO2 is out. We are now limited our physiology/anatomy of breathing here and move towards to deep breathing.

Deep Breathing

  • Increased O2 in tissue reduces the stress to tissue and put in comfort status hence improve body’s tissue functions.
  • However, increased CO2 concentration is not relatively harmful by this way. It strengthen the capacity of doing physical exercise and hence build the body strength
