Healthy breathing occurs with a healthy balance between breathing in oxygen and breathing out carbon dioxide. While hyperventilating, you upset this balance by exhaling more than you inhale. This causes a rapid reduction in carbon dioxide in the body.
Low carbon dioxide levels eventually lead to narrowing of the blood vessels that supply blood to the brain. This reduction in blood supply to the brain leads to symptoms like lightheadedness and tingling in the fingers. Severe hyperventilation can lead to loss of consciousness.
For some people, hyperventilation is rare, and only occurs as an occasional, panicked response to fear, stress, or a phobia. For others, this condition occurs regularly as a typical response to emotional states, such as depression, anxiety, or anger. When hyperventilation is a frequent occurrence, this is known as hyperventilation syndrome.
Hyperoxic brain effects are normalized by addition of CO2
Abstract
BACKGROUND: Hyperoxic ventilation (>21% O2) is widely used in medical practice for resuscitation, stroke intervention, and chronic supplementation. However, despite the objective of improving tissue oxygen delivery, hyperoxic ventilation can accentuate ischemia and impair that outcome. Hyperoxia results in, paradoxically, increased ventilation, which leads to hypocapnia, diminishing cerebral blood flow and hindering oxygen delivery. Hyperoxic delivery induces other systemic changes, including increased plasma insulin and glucagon levels and reduced myocardial contractility and relaxation, which may derive partially from neurally mediated hormonal and sympathetic outflow. Several cortical, limbic, and cerebellar brain areas regulate these autonomic processes. The aim of this study was to assess recruitment of these regions in response to hyperoxia and to determine whether any response would be countered by addition of CO2 to the hyperoxic gas mixture.
METHODS AND FINDINGS: We studied 14 children (mean age 11 y, range 8-15 y). We found, using functional magnetic resonance imaging, that 2 min of hyperoxic ventilation (100% O2) following a room air baseline elicited pronounced responses in autonomic and hormonal control areas, including the hypothalamus, insula, and hippocampus, throughout the challenge. The addition of 5% CO2 to 95% O2 abolished responses in the hypothalamus and lingual gyrus, substantially reduced insular, hippocampal, thalamic, and cerebellar patterns in the first 48 s, and abolished signals in those sites thereafter. Only the dorsal midbrain responded to hypercapnia, but not hyperoxia.
CONCLUSIONS: In this group of children, hyperoxic ventilation led to responses in brain areas that modify hypothalamus-mediated sympathetic and hormonal outflow; these responses were diminished by addition of CO2 to the gas mixture. This study in healthy children suggests that supplementing hyperoxic administration with CO2 may mitigate central and peripheral consequences of hyperoxia.
The simple fact is that many people breathe too much (clinically known as chronic hyperventilation), altering the natural levels of gases in the blood and leading to numerous health problems, including asthma. Habitual over-breathing is primarily due to the elements of our modern lifestyles such as processed foods, lack of exercise, pollution, smoking, and excessive talking. As a result of this, breathing volume can increase to as much as 2-3 times the norm, resulting in a variety of common complaints including lethargy, difficulty sleeping, and poor concentration. Typical characteristics of over-breathing are breathing through the mouth, noticeable breathing during rest, breathing using the upper chest, regular sighing, taking large breaths prior to talking, and breathing loudly during rest.
Developing a habit of breathing too much can have significant negative consequences for long-term health, as it reduces oxygen delivery to tissues and organs, and leads to the constriction of the smooth muscles surrounding blood vessels and airways.
Buteyko Breathing Method theory (named after the Russian physician and researcher, Professor K P Buteyko) is based on the understanding that over-breathing disturbs the balance of oxygen and carbon dioxide in our lungs. At the end of the 19th Century, carbon dioxide was found to be responsible for the bond between oxygen and haemoglobin. If the levels of carbon dioxide in the blood are lower than normal, this leads to difficulties in releasing oxygen from haemoglobin. This is known as the Bohr Effect.
In cases of severe hyperventilation and CO2 loss (hypocapnia) up to 80% of the oxygen contained in
red blood cells is returned to the lungs undelivered. This can result in a significant reduction in the oxygen supply to the brain and body tissues, a condition known as cellular hypoxia.
Loss of carbon dioxide during hyperventilation causes smooth muscle to constrict around airways and blood vessels, reducing the availability of oxygen to the brain and body tissues. Professor Buteyko maintains that this is what causes chest tightness in asthma and is the main factor in blocked noses. An asthma attack is the body’s way of attempting to reduce the airflow passing through the lungs in order to reduce carbon dioxide loss.

I followed the beginning of your directions and passed out. What about those of us who have the willpower to hold their breath until blackout?

How one can become so locked up on one thing only to forget how to "breathe" is beyond me, but you mention it well! We are in a constant mind fog and being bombarded with too much mentally.
There's only a completely degraded mental condition by the intelligence agencies who are using neurological weapons.

Where do these agencies get their employees?
As for breathing, how does your breathing technique work when you are unconscious during sleep? I'm not sure how your conscious breathing has any affect on your unconscious breathing.
