To those that mention the inhaled cold air being the same temp as normal by the time it hits your bronchials, can you tell me what system creates this heat and exchanges it? And, is there any temperature and/or air velocity and volume where this is not true that the air is “pre-heated.”
Can you also tell me where that energy comes from and explain to me how it is energy that could not otherwise be used for motion or other bio functions?
Can you also explain to me if there is a cooling mechanism for incoming air when breathing air higher than body temp?
When there is ice on the interior side of windows in my 68f home, and the air is essentially stagnant, it makes me highly suspicious of the preheating claim.
