“…The human respiratory tract is highly exposed to the external environment and is more susceptible than other body systems to the influence of external environmental factors, especially air pollutants and air temperature changes [4,5]. The prevalence and mortality of respiratory diseases, as well as the influences of air pollution and meteorological factors on respiratory diseases, have become major global health concerns [6][7][8].In China, according to the Health Statistics Yearbook (2020), respiratory diseases are the fourth leading cause of death among urban and rural residents.

Background The influences of air pollution exposure and temperature on respiratory diseases have become major global health concerns. This study investigated the relationship between ambient air pollutant concentrations and temperature in cold industrial cities that have the risk of hospitalization for respiratory diseases. Methods A time-series study was conducted in Changchun, China, from 2015 to 2019 to analyse the number of daily admissions for respiratory diseases, air pollutant concentrations, and meteorological factors. Time-series decomposition was applied to analyse the trend and characteristics of the number of admissions. Generalized additive models and distributed lag nonlinear models were constructed to explore the effects of air pollutant concentrations and temperature on the number of admissions. Results The number of daily admissions showed an increasing trend, and the seasonal fluctuation was obvious, with more daily admissions in winter and spring than in summer and autumn. There were positive and gradually decreasing lag effects of PM10, PM2.5, NO 2 , and CO concentrations on the number of admissions, whereas O 3 showed a J-shaped trend. The results showed that within the 7-day lag period, 0.5°C was the temperature associated with the lowest relative risk of admission due to respiratory disease, and extremely low and high temperatures (<-18°C, >27°C, respectively) increased the risk of hospitalization for respiratory diseases by 8.3% and 12.1%, respectively. Conclusions From 2015 to 2019, respiratory diseases in Changchun showed an increasing trend with obvious seasonality. The increased concentrations of SO 2 , NO 2 , CO, PM2.5, O 3 and PM10 lead to an increased risk of hospitalization for respiratory diseases, with a significant lag effect. Both extreme heat and cold could lead to increases in the risk of admission due to respiratory disease.

“…The widespread prevalence of seasonal respiratory viruses is apparently dependent on air temperature and humidity (temperature is listed as a major factor); however, due to different climates in different regions, the correlation between temperature and the seasonality of these diseases is distorted [12][13] . Thus, the spread of respiratory viruses, as well as the impact of meteorological factors on respiratory diseases and mortality, has become a serious problem in global health 14 .…”

The study evaluates the impact of air temperature on the pathogenesis and epidemiology of COVID-19, using the example of the pandemic wave caused by the Omicron strain in Tomsk. The results show that any short-term decrease in daily temperature by more than 3°C has a significant impact on the course of the disease in infected individuals, leading to an increase in severity and symptoms of the disease, and consequently, in the number of hospitalizations with a lag of 1-2 days after exposure. The findings can help healthcare systems and the population develop more effective preventive measures and protect those at greatest risk from serious complications. The study also highlights the potential use of temperature changes to predict hospitalizations, aiding clinics and medical facilities in quickly preparing for an influx of critically ill patients. Further detailed research is required.
