The lungs are the main players of the respiratory system.
The right lung is a little wider than the left lung, but it is also shorter. The right lung is shorter because it has to make room for the liver, which is right beneath it. The left lung is narrower because it must make room for the heart. At rest, a man’s lungs can hold around 750 cubic centimeters of air, while a woman’s can hold around 285 to 393 cc of air.
On average we take 15 to 20 breaths a minute, which comes to around 20,000 breaths a day. Babies tend to breath faster ,a newborn’s breathing rate is about 40 times each minute.
With deep breathing been scientifically proven to affect the heart, the brain, digestion, the immune system positive way.
We can train the body’s reaction to stressful situations and dampen the production of harmful stress hormones. With slow, deep breathing stimulates the opposing parasympathetic reaction to calms down the stress response. The sympathetic nervous system fills your body with all that cortisol and adrenaline(stress) deep breathing reduces it and calms the brain.
Researchers of Neuroscience found that focused breathing affects levels of noradrenaline, a natural brain chemical messenger. Noradrenaline gets released into the bloodstream when you are curious, focused, or emotionally aroused. It enhances your attention to detail and improves overall brain health by promoting the growth of new neural connections.
When you’re stressed, you produce too much noradrenaline, making it difficult to focus. When you’re feeling lethargic, you produce too little of it, which also makes it hard to focus. By focusing on regulating your breathing you can optimize your attention level and likewise, by focusing on your attention level, your breathing becomes more synchronized.
Breathing exercises also help to counter the accumulation of minor physical tension associated with stress. 365 breathing exercise means do 3 times a day 6 cycles of breathing a minute for 5 minutes. That means breathe in to the count of 5 then breathe out to the count of 5 for a minute repeat this up to 5 minutes.
Therapists recommend doing breathing exercises regularly during the day. Some studies suggested in addition to providing immediate relief, regular breathing exercises can make you less vulnerable to stress, by permanently modifying brain circuits. In a practice that may seem counterintuitive, however, counselors may encourage some anxious patients to breathe rapidly instead of slowly, as part of an effort to train them to cope with their anxieties.
