“…A simple statistical analysis of two, or more, distant factors (in this study: LP levels and meteorological conditions) is always burdened with some risk of indirect correlations. For instance, a larger number of cardiovascular deaths in the winter season may be attributed to the direct response of the organism to cold stress (e.g., increase of arterial blood pressure), may be secondary to seasonal increases in respiratory tract infections, or may be associated with decreases in vitamin D3 levels in winter [28,29,30,31,32]. It may also be the result of any combination of these factors as well as many others.…”

Lipid disorders, especially hypercholesterolemia, are one of the most thoroughly investigated cardiovascular risk factors. Their correlation with biometeorological conditions has been reported, with authors stressing seasonal increases of total cholesterol (TC) levels, mostly occurring in winter. This study aims at determining the correlation between the level of lipid parameters (LP) and meteorological conditions, analyzing seasonal variations in LP levels, and attempting to answer the following questions: do changes in LP levels result from the organism’s response to cold or heat stress, or are they secondary to seasonal dietary variations? An observational study comprised ambulatory patients from the city of Olsztyn (Poland), for whom laboratory test were performed in 2016–2018, with 106,325 records of TC, high-density lipoprotein (HDL), and triglycerides (TG). LP levels were matched with atmospheric conditions on the day when the test was conducted and expressed by the universal thermal climate index (UTCI). We demonstrated seasonal increases of TC in cold stress (in wintertime) and of TG in heat stress (summer). The analysis of LP levels in specific periods revealed the increase of TC levels after holidays (i.e., Christmas and Easter) in men by 4.56%, and the increase of TG levels in women by 13.46% in the same period. Our results suggest the secondary, diet-dependent underlying cause of the observed changes. This work contributes to the discussion concerning the impact of biometeorological factors on LP levels and may be of significance when planning population-dedicated preventive activities.

“…high levels of heat stress, extended exposure to extreme levels of cold stress can impact human health, reduce the efficiency of performed activities, lead to frost bite, hypothermia or even death when the exposure impairs thermoregulation [4] [5] [6] [7] [8]. Cold stress is a significant risk factor among patients, particularly women with cardiovascular diseases [9]. Unlike heat waves, during which mortality raises for several days, cold spells may increase levels of mortality for several weeks [5].…”

Data from 456 surface meteorological sites in Alaska, eastern Russia and northwest Canada for 1979-2017 were used to model hourly universal thermal comfort indices (UTCIs) under consideration of Alaska-appropriate clothing. The results served to determine a high-resolution climatology of thermal comfort levels for Alaska at various temporal and spatial scales as well as the frequency of thermal stress levels. On 1979-2017 average, various degrees of cold stress occurred with highest percentage on the Alaska West Coast and along the Arctic Ocean. In the continental and Inside Passage region, no thermal stress had the highest percentage of occurrence. In Interior Alaska, both strong heat and extreme cold stress occurred occasionally. At most sites and in all Alaska Köppen-Geiger bio-climate regions, the absolute range between monthly means of daily minimum and maximum UTCIs was larger than that of monthly means of daily minimum and maximum air temperatures. Major contributors to thermal discomfort (shortwave radiation, air temperature, moisture, wind speed) varied among bio-climate regions and in the diurnal and annual courses.

“…Cold is among the environmental stressors and exhibits various effects on organisms. Cold stress stands out as a risk factor for cardiovascular diseases in a community, especially for women (20). While acute cold stress may pose critical health problems for people living in cold climates, chronic cold stress is a serious issue particularly for people working outdoors.…”

Objective: Cold is a stress-inducing factor that can cause changes in bladder function in various ways. The present study is intended to investigate the effects of corticosteroid and antihistaminic treatment on acutely and chronically induced cold stress. Material and Methods: Forty-two female rats were randomly divided into seven groups as follows: Control group; Acute cold-stress (ACS) group; ACS+ corticosteroid (CORT) group; ACS+CORT + Antihistaminic group; Cronic cold-stres (CCS) group; CSS+CORT group; CSS+CORT+Antihistaminic group. On the 15th day after these treatments, bladders of the rats were harvested for histopathological examinations under general anesthesia and fixed with 10% neutral buffered formaline. Hematoxylin and eosin and toluidine blue stainings were performed. Results: The comparison based on mast cell count yielded the highest value in the CCS group in comparison to the control group. The lowest value was harvested in the CCS + CORT group. The comparison between the CCS groups revealed the highest polymorphonuclear leucocyte (PNL) values in the lamina propria in the CCS group, whereas the CORT and CORT + Antihistaminic treatments were found to have significantly decreased the PNL values in the lamina propria. While the PNL counts in the epithelium were high in the ACS and CCS groups, the results in the ACS and CCS groups that were treated with CORT and/or antihistaminic were revealed to be similar with those in the control group. It was discovered that antihistaminic injection in addition to CORT decreased the lymphocyte counts in epithelium in CCS more efficiently than CORT alone did. Conclusion: The present research revealed that corticosteroid treatment reduced inflammatory cell infiltration and decreased mast cell count. A more evident amelioration was observed particularly in chronic cold stress.
