Abstract:
Objective To explore the effects of airflow stimuli on human immunoglobulin concentrations in a warm environment,and to discuss and analyze the correlations between immunoglobulin concentrations and subjective questionnaires results.Methods Dynamic airflow of different modes was created by a modified wind blowing device in the climate chamber.Then the changes of S-IgA and S-IgE concentrations of 12 subjects exposed to different airflow environments were measured,during which the TSV,TCV,draught perception,satisfaction with the airflow,and airflow discomfort symptom polling of the subjects were investigated.Results The S-IgA concentration increased by 56.3%after blowing in the warm environment,but the subsequent high air speed condition resulted in a decrease of S-IgA concentration by 24.8%.Both S-IgA and S-IgE had the highest concentrations when the TSV was neutral,and the S-IgA concentration was 176%higher under comfortable conditions than that under uncomfortable conditions.The S-IgA concentration showed an inverted"U"-shaped relationship with the average wind speed,and the highest S-IgA concentration was observed when the mean air speed was 1.0 m/s.Conclusion Dynamic airflow has a significant effect on S-IgA concentration but little effect on S-IgE concentration.Comfortable airflow in a warm environment could benefit the S-IgA concentration elevation thus the respiratory immunity.However,a strong draught perception caused by high wind speeds and an unsatisfactory airflow environment can lead to lower S-IgA concentrations.
