“…Another investigator reported that air conditioning can reduce mite density if it decreases relative humidity to below 50% (29). On the other hand, a recent Japanese study (30) found that specific mite populations, including Der p, were significantly higher in homes with air conditioning. Japanese urban areas are very humid compared with the USA in summer.…”

“…Thus, the intensive use of air conditioners is likely to reduce the indoor absolute humidity to the 13 g/m 3 level as opposed to the outdoor level of 21 g/m 3 . However, the relative humidity in a room with air conditioning rapidly increases locally near the wall and floor when the air conditioning stops and outdoor air enters (30), because the relative humidity becomes higher as the temperature decreases due to reduced saturated vapor pressure, thus leading to a favorable local climate for mite proliferation. This study has demonstrated a significantly positive relationship between the intensive use of air conditioning in hot weather and atopic sensitization.…”

INTRODUCTION:Air conditioner by lowering temperature may affect human health since it has profound effect on our environment. Modern styles of living in urban areas have been considered potentially responsible for the development of airway allergic diseases due to proliferating house dust mites & increasing concentration of indoor air pollutants, which lead to the elevation of serum Ig E levels or the enhancement of eosinophil activity. AIMS AND OBJECTIVE: To assess the effect of air conditioners (AC) on pulmonary functions in young healthy non-smoker male. MATERIALS AND METHODS: The study group comprised of 20 male subjects who were using AC's in their cars for at least 1 hr daily since last 6 months. While 20 male subjects who did not use AC at all served as controls. The pulmonary functions were assessed using Power lab 8/30 series with dual bio Amp/stimulator, manufactured by AD instruments, Australia, in a closed room the outcome of pulmonary function tests was presented as a mean ± SD for each of the parameter. The two groups were compared by applying unpaired 't' test and P value of less than 0.05 was considered as significant. RESULTS: The peak expiratory flow rate (PEFR) and Forced expiratory flow between 25-75% of vital capacity(FEF25-75) were significantly reduced in subjects using car AC's. CONCLUSION: In the presence of normal FEV1, reduced FEF 25-75%, which is the flow rate over the middle half of vital capacity, is an evidence of mild airflow limitation. The result is suggestive of predisposition of AC users towards respiratory disorders in form of mild airflow restriction

[19] Post-operative fungal infections may be caused by discharge of spores from contaminated air conditioning units. [20] The filters of such units may act as a nidus for the growth of fungi according to the study done in 25 operating theatres in India over 2 years.…”

Background: Modernization has been implicated in the pathogenesis of allergic airway diseases. House dust, mites, and indoor air pollutants have been reported to cause elevation of serum IgE levels and/or enhancement of eosinophil activity. A component of modern lifestyle is the intense use of air-conditioners (AC) that has increased the risk of atopic sensitization. Aim: To assess the effect of air conditioners on pulmonary function tests in healthy non-smokers. Methods: The study included 100 subjects using AC and 100 subjects who were not using AC. After ethical committee approval, pulmonary function tests were done for both study groups by using Medspiror. The data obtained was tabulated and analyzed. Results: The lung functions particularly Forced vital capacity (FVC), and Forced expiratory volume in 1 second (FEV 1) , were affected more in AC users. FVC and FEV 1 were found to be significantly reduced and FEV 1 /FVC was found to be normal. Conclusion: As FVC and FEVFEV 1 were found to be significantly reduced and FEV1/FVC was found to be normal, this is suggestive of predisposition of AC users towards restrictive type of respiratory disorders.
