belfegyelmezés

Belfegyelmezés refers to the act of holding one's breath, either voluntarily or involuntarily. It is a physiological response that can occur for various reasons, including during strenuous physical activity, as a reaction to pain or surprise, or as part of certain meditation or training techniques. Involuntary breath-holding often happens when a person is submerged in water or experiences a sudden shock. Voluntary breath-holding is commonly practiced in freediving, where athletes train to extend their underwater time by consciously controlling their breathing. It can also be a component of Pranayama, a yogic practice focused on breath control. The body's urge to breathe is triggered by a buildup of carbon dioxide rather than a lack of oxygen. During a period of breath-holding, carbon dioxide levels rise, stimulating the diaphragm and intercostal muscles to initiate breathing. With training, individuals can increase their tolerance to higher carbon dioxide levels and delay the urge to breathe, though there are physiological limits to this. Prolonged or extreme breath-holding can lead to dizziness, fainting, and in severe cases, brain damage or death.
