Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Over-breathing due to stress impairs oxygen bioavailability to cellular processes.

◐Partially SupportedThe lower lobes of the lungs receive more blood flow due to gravity, leading to differential oxygen transfer across the alveoli into the blood.

◐Partially SupportedMouth breathing reduces O2 absorption and causes excessive offloading of CO2, disrupting the CO2-O2 dissociation effect and reducing oxygen bioavailability.

◐Partially SupportedA normal respiration rate is 17 to 20 breaths per minute.

◐Partially SupportedOver-breathing shifts the body towards sympathetic activity and reliance on anaerobic processes due to insufficient oxygen.

◐Partially SupportedModern humans often exist in a state of mid-range sympathetic nervous system activity.
