It sounds like vasodilation, the small vessels close to the skin opening up, usually as a result some sort of stimulus, drugs, heat, alcohol, and emotion are the usual culprits, but I'm wondering if the reduced pressure of altitude could be affecting things.
Sounds of no consequence, medically, but the usual disclaimer, "Any information gleaned from this forum MUST be backed up by consulting your state-registered health professional or AME."
Interesting fact- ever noticed how your loved one looks quite attractive when angry?- usually because the same physiological mechanisms which increase the breathing, cause perspiration, flush the face, flare the nostrils, dilate the pupils, etc occur both when angry, and when falling in love.
