BREATHS keep going this body! God given OXYGEN, the air, needs to be consciously breathed in deep but slow (10-12 breaths per minute) regularly especially when moving more! Move more, Live more!

The basic calculations provided by PhysiologyWalla are physiologically sound! At a resting tidal volume of 500 mL and a respiratory rate of 15 breaths/minute, the minute ventilation is 7.5 L/min, totaling 450–500 L/hour!

With a resting oxygen consumption of approximately 250 mL/min (15 L/hour), and given that air is ~21% oxygen, the “75 liters of air” required for basic metabolism is accurate! Therefore, if moving more, breathe more deeply but slowly in and out!

Breath Stacking: By layering inhalations, you increase mean airway pressure; it does increase alveolar recruitment and may slightly enhance oxygen diffusion into the plasma by Henry’s Law!

The Vagus Nerve: Deep, controlled breathing (especially prolonged exhalation) stimulates the Hering-Breuer reflex and the parasympathetic nervous system, effectively reducing cortisol and heart rate.

Humming (Bhramari): Research suggests humming increases nasal Nitric Oxide (NO) production by up to 15-fold, which acts as a vasodilator and bronchodilator!

The Silicon Bag (Resistance Training): Blowing against resistance acts as PEEP (Positive End-Expiratory Pressure), which prevents premature airway closure in patients with high “closing volumes.”!
