“…But there are also reports of cases with distinctly less asthma-related emergencies, e.g. seven cases in Naples were reported by D'Amato et al (2008) or 14 in New Zealand by Sabih et al (2020). For the latter, it can be expected that they did not lead to a capacity overload of medical care services.…”

Higher incidences of asthma during thunderstorms can pose a serious health risk. In this study, we estimate the thunderstorm asthma risk using statistical methods, with special focus on Bavaria, Southern Germany. In this approach, a dataset of asthma-related emergency cases for the study region is combined with meteorological variables and aeroallergen data to identify statistical relationships between the occurrence of asthma (predictand) and different environmental parameters (set of predictors). On the one hand, the results provide evidence for a weak but significant relationship between atmospheric stability indices and asthma emergencies in the region, but also show that currently thunderstorm asthma is not a major concern in Bavaria due to overall low incidences. As thunderstorm asthma can have severe consequences for allergic patients, the presented approach can be important for the development of emergency strategies in regions affected by thunderstorm asthma and under present and future climate change conditions.

These events were accompanied by five to tenfold increases in admission numbers of asthma patients in emergency units.…”

“…What is more, lower air pressure tends to occur during extreme weather, such as thunderstorms, which has been linked to asthma exacerbations, known as "thunderstorm asthma." [37][38][39] Studies of weather events have found that thunderstorm would increase the levels of respiratory allergens present in the air, particularly pollen and mold spores. 37,40 Conditions at the beginning of a thunderstorm can cause pollen grains to rupture, increasing the concentration of pollen debris.…”

Purpose Asthma has a major impact on patients’ quality of life, mortality, and healthcare burden. Some evidence suggests that environmental factors may trigger asthma. However, there has been limited research on the relationship between air pressure and asthma hospital admissions, especially in China. Thus, we aimed to study the influence of air pressure and identify potentially susceptible populations. Methods The study data were gathered from hospitalization records with a primary diagnosis of asthma from all secondary and tertiary hospitals in Beijing from January 1, 2013, to December 31, 2016. The study examined the association between the risk of asthma and air pressure using a distributed lag non-linear model (DLNM). We also performed a stratified analysis to identify the susceptible populations. Results A total of 23,697 asthma hospital admissions were included in the study. We found that the relative risk (RR) and the 7-day cumulative relative risk (CRR) of asthma had an approximate negative correlation with air pressure. At the same time, we found that the association was most apparent on the day of exposure (lag = 0). Conclusion Ambient air pressure had an approximately negative correlation with daily asthma hospital admissions in Beijing, China. That means the risk of hospital admission for asthma would be increased by low air pressure. Furthermore, air pressure has a significant effect on asthma only on the day of exposure. It is possibly significant to protect the vulnerable on days with low air pressure, especially those younger than 65 years.

“…These findings suggest that past increases in particulate matter concentration and temperature may be the dominant mechanism of storm-associated acute respiratory illness in older Americans, which may contribute to a burden on the health care system as storm activity increases with storm, increase in global temperatures [36]. Thunderstorm was considered unlikely to occur in New Zealand due to its local weather patterns, but events on 2 nd December 2017 led to an increase in asthma hospitalizations at Waikato Hospital in Hamilton, with similar presentations to international descriptions of asthma by storm [44]. Ali et al [35] reported cases of near-fatal and fatal asthma caused by storms in Kuwait on December 1 st , 2016; 17 patients were admitted with near-fatal asthma, 93.8% had a previous history of asthma, with an average duration of 9 years, 33.3% reported receiving inhaled corticosteroids from their physician and 93.8% relying only on a short-acting β2-agonist to control their asthma; 68.8% reported being outdoors during the storm and eleven patients were diagnosed with fatal asthma.…”

Thunderstorm-triggered asthma (TA) can be defined as the occurrence of acute asthma attacks immediately following a thunderstorm during pollen seasons. Outbreaks have occurred across the world during pollen season with the capacity to rapidly inundate a health care service, resulting in potentially catastrophic outcomes for allergicpatients. TA occurs when specific meteorological and aerobiological factors combine to affect predisposed atopic patients with IgE-mediated sentitization to pollen allergens. Thunderstorm outflows can concentrate aeroallergens, most commonly grass pollen but also other pollens such as Parietaria and moulds in TA, at ground level to release respirable allergenic particles after rupture by osmotic shock related to humidity and rainfall. Inhalation of high concentrations of these aeroallergens by sensitized individuals can induce early asthmatic responses which can be followed by a late inflammatory phase. There is evidence that, during pollen season, thunderstorms can induce allergic asthma outbreaks, sometimes also severe asthma crisis and sometimes deaths in patients suffering from pollen allergy. It has been observed that changes in the weather such as rain or humidity may induce hydratation of pollen grains during pollen seasons and sometimes also their fragmentation which generates atmospheric biological aerosols carrying allergens. Asthma attacks are induced for the high concentration at ground level of pollen grains which may release allergenic particles of respirable size after rupture by osmotic shock. In other words, it is a global health problem observed in several cities and areas of the world that can strike without sufficient warning, inducing sometimes severe clinical consequences also with deaths of asthma patients. Due to constant climate change, future TA events are likely to become more common, more disastrous and more unpredictable, as a consequence it is important to have deep knowledge on this topic to prevent asthma attacks. Other environmental factors, such as rapid changes in temperature and agricultural practices, also contribute to causing TA.
