How Well Do You Understand the Mechanics and Benefits of Breathing?

The Importance of Breathing: Controlling Our Mental and Physical Health

• Breathing is essential to life, and we cannot survive without it for more than a few minutes.

• How we breathe is important to our mental health, physical health, and performance.

• Breathing lies at the interface between our conscious and subconscious behavior and represents a bridge between them.

• By changing our breathing pattern, we can quickly change our brain's capability to take in new information, turn off to sleep, and regulate anxiety and focus.

• Breathing is unique among brain and bodily functions in that we can consciously take control of it at any moment.

• Oxygen and carbon dioxide are the main players in breathing, and we need both in our body to perform mental and physical functions.

• The respiratory apparatus has two major components: mechanical and chemical mechanisms.

• Hunger is an example of how mechanical and chemical mechanisms work in parallel in our body.

• Ketone supplements can increase blood ketones, improve cognitive ability and physical output.

• WHOOP is a fitness wearable device that tracks daily activity and sleep and provides real-time feedback on how to adjust training and sleep schedule to perform better.

• The podcast aims to bring zero cost to consumer information about science and science-related tools to the general public.The Mechanical and Chemical Aspects of Breathing

• Mechanical and chemical information work together in the body for functions like avoiding damage to skin and breathing.

• The respiratory system involves both mechanical and chemical components, including the nose, mouth, lungs, and bloodstream.

• The physiological sigh, which involves two deep inhales and a full exhale, is the most efficient way to reduce stress quickly because it optimally balances oxygen and carbon dioxide.

• Overbreathing, or breathing too often and removing too much carbon dioxide, can put the body in a hypoxic state and negatively affect oxygen delivery to the brain and tissues.

• The mechanical components of breathing include the nose, mouth, larynx, lungs, alveoli, diaphragm, and intercostal muscles between the ribs.

• The phrenic nerve controls the diaphragm and has both motor and sensory neurons that allow for diaphragmatic breathing, where the belly moves outward on inhales and inward on exhales.

• The intercostal muscles between the ribs also play a role in breathing and can be used in conjunction with diaphragmatic breathing.

• There is no evidence that diaphragmatic breathing is inherently better than rib cage breathing, but being able to control both independently or together can regulate mental and physical states.

• The larynx needs to be rigid to prevent collapse during breathing, unlike the lungs which need to expand and contract.

• Understanding the mechanical and chemical aspects of breathing can help with stress reduction and overall health.

• Physical movement and cramps can be related to the diaphragm and its connections to the liver.

• Breathing can alter personality in positive ways, leading to more calmness, focus, alertness, and improved health.The Mechanics and Chemistry of Breathing

• The larynx is rigid and crucial for the breathing system.

• Nose and mouth have different resistances to air, and breathing through the nose provides increased resistance, allowing more air to be drawn into the system.

• Breathing in through the nose is harder but brings more oxygen into the system.

• Carbon dioxide plays a critical role in delivering oxygen to the cells and tissues of the body.

• Excess carbon dioxide can induce panic attacks even in people who lack an amygdala.

• The body needs enough carbon dioxide and enough oxygen, but not too much.

• Carbon dioxide changes the shape of hemoglobin to liberate oxygen from it.

• Exhaling removes carbon dioxide from the bloodstream.

• Hyperventilation brings in more oxygen but removes more carbon dioxide, inducing a state of hypocapnic hypoxia.

• Hypocapnia reduces levels of carbon dioxide relative to normal, causing anxiety, vasoconstriction, and tingling in the periphery.

• The body needs both oxygen and carbon dioxide, and adjusting their ratios can be useful depending on immediate needs and planned activities.

• Athletic Greens is a vitamin mineral probiotic drink that covers all foundational nutritional needs, and it contains probiotics optimal and vital for microbiota health.The Importance of Breathing: Understanding High Altitude Breathing and Sleep Apnea

• Breathing at high altitudes requires more effort due to the low air pressure, making it harder to fill the lungs with air.

• Inhaling is an active process while exhaling is passive, and the lack of pressure gradient at high altitudes makes inhaling more difficult.

• Changes in atmospheric gases at high altitudes can impact the amount of oxygen brought into the body, leading to lightheadedness and headaches.

• Sleep apnea, a condition where people underbreathe during sleep, can lead to hypoxia and a range of health concerns like cardiovascular events and cognitive dysfunction.

• Excessive daytime sleepiness, anxiety, and snoring are signs of sleep apnea, and treatment options include CPAP machines or behavioral interventions like nasal breathing.

• Shifting to nasal breathing during sleep can offset sleep apnea and snoring, and taping the mouth shut or being conscious of keeping the mouth shut can train the body to breathe properly.

• Becoming a nasal breather during the daytime through deliberate actions can transfer to nighttime breathing patterns and allow for less sleep apnea.

• The phrenic nerve innervates the diaphragm and allows for the lungs to fill up, and there are two brain areas that control breathing: the pre-Botzinger complex and the cortex.

• The pre-Botzinger complex controls all rhythmic aspects of breathing, while the cortex controls voluntary control of breathing.

• Exogenous opioids like fentanyl bind to opioid receptors on the pre-Botzinger complex and shut it down, leading to respiratory failure and death.

• Breathing exercises like deliberate hyperventilation and breath holds can increase oxygen delivery to the cells and help with altitude adaptation.

• Proper breathing during sleep and in daily life can have positive health and aesthetic effects, and behavioral interventions like nasal breathing can be more cost-effective than CPAP machines.
