Abstract
Background: With its potentially conflicting physiological roles of both air-conditioning and body-heat recovery, the response of nasal mucosa blood flow (NMBF) to ambient cold air is not well unDerstood. Objective: To evaluate the NMBF in response to cold ambient air. Methods: The NMBF was continuously measured by laser Doppler flowmetry in nine participants exposed to different air temperatures (24°C and 4°C). Results: The NMBF significantly Decreased at 4°C compared with that at 24°C (p<0.01). Conclusion: The response to ambient cold air in the nasal microcirculation is similar to that of the body-surface blood vessels, suggesting that body-heat recovery rather than air-conditioning is the predominant function.
