The Hidden Performance Factor
This article examines the growing body of peer-reviewed research demonstrating how dry air - whether from cold weather, climate-controlled gyms, or high-altitude training - impairs…
August 27, 202640+ years" of HME clinical use
Directionally supported by literature on HME/anaesthetic gas humidification research dating to the late 1970s (Chalon et al., 1979) Chalon J, Loew DA, Malebranche J. Effects of dry anesthetic gases on tracheobronchial ciliated epithelium. Anesthesiology. 1972 Sep;37(3):338-43. doi: 10.1097/00000542-197209000-00010. PMID: 4115208.

Commonly cited physiological estimate. Multiple general respiratory physiology sources place daily respiratory water loss at approximately 250-500mL/day (roughly 8.5-17 fl oz), varying with ventilation rate, humidity, and individual factors.
