A personal airway humidification apparatus includes means for generating a heated air laden with gaseous (molecular) water. The personal airway humidification apparatus further includes an accumulator coupled to the generating means for retaining a volume of the gaseous water-laden heated air prior to being delivered by natural breathing to a user and a delivery tube coupled to the accumulator. The delivery tube has a sufficiently large diameter bore to enable the users natural breathing to draw the gaseous water-laden heated air from the accumulator and through the delivery tube. The personal airway humidification apparatus also includes a one-way valve coupled to the delivery tube for venting exhalations of the user to atmosphere and preventing the exhalations from being exhaled back into the delivery tube and an interface device by which the gaseous water-laden heated air enters the users mouth from the delivery tube.
