Evaporative water loss from the airways can lead to bronchoconstriction via airway cooling and rewarming and/or by airway dehydration and an increase in osmolarity of the airways. Dehydration is important for all temperatures of dry air, whereas cooling and rewarming will be additionally important when exercise is performed in subfreezing air conditions but become less so as warmer air is inspired.
