The Positive Effect of Climate on Allergic Rhinitis

Abstract

Allergic rhinitis is a growing global health issue, which is one of the most popular chronic diseases. Its prevalence is influenced by both environmental exposures and climatic factors. Therefore, this study aims to give the view of the positive effects of the climate to allergic rhinitis from the past paper, including the characteristics of the disease, relevant climate factors, pollution and geographical factors. The hypersensitivity response to allergens, mediated by immunoglobulin E (IgE), triggers allergic rhinitis, and children have a high prevalence of this condition. The symptoms include nasal symptoms, such as nasal congestion and rhinorrhoea, as well as extra-nasal manifestations such as sinus pressure, eustachian tube dysfunction, and headache. Air pollution can exacerbate allergic responses, and natural allergens are correlated with disease risk. The temperature positively correlates with prevalence. Global warming lifts the factors that directly related to the temperature, humidity and concentration of carbon dioxide, high temperature, humidity and carbon dioxide concentration correlate with increased pollen load and ability to cause allergic inflammatory response through global warming, as well as the higher concentration of spores of fungus and mould in atmosphere. Some extreme weather events that related to global warming, such as wildfire and flood, increase their frequency and intensity as well as the related allergens. The latitude and altitude have a negative correlation with the prevalence of allergic rhinitis in general. The urban resident a higher prevalence, considering the increased air pollution and the natural allergen due to heat islands. The region with different climate type shows diverse main allergens and highincidence season.
