Heat exchange in the nose

M Taylor, S C Shores

    The Laryngoscope
    |October 1, 1981
    PubMed
    Summary

    Nasal exhalation significantly impacts the lower respiratory tract and body metabolism by altering heat and water loss. These effects, controlled by the autonomic nervous system, are crucial for balancing bodily heat production and loss.

    Area of Science:

    • Physiology
    • Respiratory Medicine
    • Metabolic Studies

    Background:

    • Research on nasal respiration has predominantly focused on inspiratory effects.
    • Nasal expiratory function and its physiological impacts remain less explored.
    • The nasal mucosa plays a role in regulating body heat and water balance.

    Purpose of the Study:

    • To investigate the effects of nasal expiration on the lower respiratory tract.
    • To examine the influence of nasal expiration on general metabolic processes.
    • To understand the role of the nasal mucosa in thermoregulation and water balance.

    Main Methods:

    • Animal studies detailing nasal expiration effects.
    • Analysis of heat and water loss alterations.
    • Investigation of autonomic nervous system control over nasal mucosal changes.

    Main Results:

    • Nasal expiration profoundly affects the lower respiratory tract and metabolic processes.
    • Changes in nasal mucosa alter body heat and water loss.
    • Autonomic nervous system regulates these mucosal changes to balance heat production and loss.

    Conclusions:

    • Nasal expiration is a critical factor in respiratory and metabolic regulation.
    • The nasal mucosa's role in thermoregulation is significant and under nervous system control.
    • Findings have implications for clinical practice and understanding environmental physiology.
