Effects of low humidity on comfort, health, and indoor environmental quality: literature review

Hamehkasi, Maryam January 1900 (has links)
Master of Science / Department of Biological & Agricultural Engineering / Melanie M. Derby / Ronaldo G. Maghirang / This study was conducted to investigate the effects of humidity on comfort, health, and indoor environment quality (IEQ) using a comprehensive literature review. Published papers were obtained from keyword and citation searches from bibliographic databases (i.e., PubMed, Scopus, and Google Scholar), including papers from 1985 to 2015. Over 600 papers were identified and classified based on topic area; from these papers, seven were chosen as case studies for this report. The seven papers represent studies on various topics, including bacteria, influenza/virus transmission, elderly subjects, indoor air quality, effects on eyes and skin, dust mites, and asthma. Theunissen et al. (1993) showed bacteria (gram positive and gram negative) do not act the same in low or high humidity conditions. Lowen et al. (2007) studied influenza transmission. Sunwoo et al. (2006) used elderly subjects to study eyes, skin, and comfort. Reinikianen et al. (1992) and Nordström et al. (1994) surveyed a large number of subjects, controlled humidity, and assessed multiple factors regarding indoor health and comfort. Arlian et al. (2001) implemented dehumidifier as a way to reduce house dust mites. Kaminsky et al. (1995) tested asthmatic subjects and healthy subjects to compare the effects of dry air on asthma. From these case studies low humidity appeared to have a variety of effects on health and comfort; however, no precise and defined borderline exists to distinguish acceptable low humidity. Acceptable low humidity levels depend on many factors, including building location and purpose, age of occupants, and climatic conditions.

Characterizing Humidity, Sex, and B-Cell Gene Regulation in Fungal Allergic Asthma

Kusick, Emma Claire January 2020 (has links)
Asthma is a debilitating lung disease that affects nearly 300 million people worldwide. Environments with high humidity and subsequent mold exposure often trigger allergic asthma. Sex differences have been reported in the incidence, prevalence, and severity of asthma. B-lymphocytes are recruited in high numbers to the allergic lung in response to the inhalation of Aspergillus fumigatus mold spores (conidia). In this work, we used a mouse model of allergic fungal asthma to assess environmental humidity, sex, and B-lymphocytes in an inhalational model of allergic fungal asthma. Our results showed that animals sensitized in low humidity conditions had no airway hyperresponsiveness (AHR), inflammation, but an increase in IgG3 antibody production. Males weighed more than females, female mice had more fibrosis and produced more IgG3 Ab, but sex showed no impact on low humidity. C19+ B-lymphocytes differentially downregulated multiple genes related to allergic asthma returning the body to homeostasis.
