“…Although limited epidemiological studies have explored the health effects of humidity, similar findings have been reported in previous studies on other eye diseases. Based on a study of 100,636 participants, relative humidity was negatively related to allergic conjunctivitis ( 10 ). In Zhong et al's study ( 13 ), there is also a negative link between relative humidity and dry eye disease, supporting the evidence from a Korean study ( 11 ), suggesting that the moisture in the air might have contributed to the maintenance of the tear film on the ocular surface.…”

“…Studies have also suggested a relationship between both humidity and temperature and eye diseases ( 9 ). Zhong et al found that relative humidity was negatively related to allergic conjunctivitis and there was a 5.8% reduction in allergic conjunctivitis occurrence for every 10% increase in relative humidity ( 10 ). A cross-sectional study of South Korean population revealed a negative association between dry eye disease and relative humidity levels ( 11 ).…”

BackgroundThe burden of cataracts was substantial in the current aging world. However, few epidemiological studies have examined the associations between climate and weather conditions and cataract in older populations. We aimed to investigate the associations of air relative humidity and temperature with cataracts in older adults in China.MethodsWe used the cohort data from 2002, 2005, 2008, 2011, 2014, and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). A total of 62,595 Chinese older adults aged between 65 and 105 years were included in the analyses. City-level annual average air humidity and temperature during 2001 and 2017 (before the survey year) was used to measure population exposure. A cataract was self-reports based on the medical record or the doctor's diagnosis and 8,071 older adults had cataract. Covariates included socio-demographic, health status, lifestyles, and chronic conditions. We adopted the Generalized estimation equation (GEE) model to analyze the associations of relative humidity and temperature with cataracts.ResultsWe found that the average relative humidity (OR: 0.99; 95% CI: 0.98–0.99) in the past year was inversely associated with cataract likelihoods in older adults and a positive association between temperature (OR: 1.04; 95%CI: 1.03,1.05) in the past year and cataract likelihoods in older adults. The associations were robust in stratified analyses by sex, urban/rural residence, and education level. Furthermore, we found a nonlinear J-shaped relationship between temperature and cataract prevalence.ConclusionOur findings provide the evidence that higher temperature and low relative humidity may be associated with cataracts in older adults.

“…41 The increase in exposure to high concentrations (> 10 μg/m 3 ) of CO, NO 2 , SO 2 , O 3 or PM, whether in the days before or on the day of emergency room care, has been accompanied by a significant increase in visits for conjunctivitis, as well as symptoms. [42][43][44][45][46][47] In addition, hot weather and strong winds, combined with the spread of pollen allergens, can potentiate these effects leading to ocular surface instability. 48 Generally, the most severe forms of conjunctivitis are associated with greater damage related to environmental pollution.…”

A alergia ocular, também conhecida como conjuntivite alérgica (CA), é uma reação de hipersensibilidade mediada por imunoglobulina E (IgE) do olho desencadeada por aeroalérgenos, principalmente ácaros da poeira doméstica e pólen de gramíneas. Os sintomas geralmente consistem em prurido ocular ou periocular, lacrimejamento e olhos vermelhos que podem estar presentes durante todo o ano ou sazonalmente. A alergia ocular tem frequência elevada, é subdiagnosticada e pode ser debilitante para o paciente. É potencialmente danosa para a visão, nos casos em que ocasiona cicatrização corneana grave, e na maioria dos pacientes associa-se a outros quadros alérgicos, principalmente rinite, asma e dermatite atópica. É classificada em conjuntivite alérgica perene, conjuntivite alérgica sazonal, ceratoconjuntivite atópica e ceratoconjuntivite vernal. O diagnóstico procura evidenciar o agente etiológico e a confirmação se dá pela realização do teste de provocação conjuntival. O tratamento baseia-se em evitar o contato com os desencadeantes, lubrificação, anti-histamínicos tópicos, estabilizadores de mastócitos, imunossupressores e imunoterapia específica com o objetivo de obter o controle e prevenir as complicações da doença.Descritores: Alergia ocular, conjuntivite alérgica, rinoconjuntivite.Ocular allergy, also known as allergic conjunctivitis, is an immunoglobulin E-mediated hypersensitivity reaction of the eye triggered by airborne allergens, primarily house dust mites and grass pollen. Symptoms usually consist of ocular or periocular itching, watery eyes, and red eyes that may be present year-round or seasonally. Ocular allergy has a high frequency, is underdiagnosed, and can be debilitating for the patient. It is potentially harmful to vision in cases of severe corneal scarring, and in most patients, it is associated with other allergic conditions, especially rhinitis, asthma, and atopic dermatitis. It is classified as perennial allergic conjunctivitis, seasonal allergic conjunctivitis, atopic keratoconjunctivitis, and vernal keratoconjunctivitis. Diagnosis seeks to identify the etiologic agent, and confirmation is given by conjunctival provocation testing. Treatment is based on avoiding contact with triggers, lubrication, topical antihistamines, mast cell stabilizers, immunosuppressants, and specific immunotherapy with the aim of achieving control and preventing disease complications.

“…To enable comparison with the results of the baseline regression shown in columns (1) and (4) of Table 2, two stage least square(2SLS) regression with IV was then used in columns (1) and (3) of Table 4. In the estimation, the Cragg−Donald F-statistic for the first-stage regression is greater than 10, indicating that there is no weak instrumental variable problem, and the model's estimations regarding the effect of air pollution are robust.…”

“…Numerous epidemiological studies have shown that air pollution can damage people’s health. The health risks associated with air pollution are mainly manifested in changes in respiratory and cardiovascular functions, such as increased susceptibility to allergy [ 1 ], asthma [ 2 , 3 ] and heart attacks [ 4 ]. In addition, air pollution can also cause more subtle problems, such as changes in blood pressure [ 5 ], mild headaches, and irritations of the ears, nose, and throat [ 4 , 6 ].…”

In recent years, the health and economic effects of air pollution have attracted considerable attention, and health and insurance services have been closely related to residents’ welfare. However, there are few studies on the influence of pollution on household purchases of insurance. Using data from the 2013 and 2015 China Household Finance Surveys, this study investigates the effect of air pollution on insurance purchases using Logit and Poisson regression models. It is found that air pollution significantly increases the probability of household insurance purchases and the level of premium expenditure, although the impact of air pollution on insurance purchases shows a degree of heterogeneity. Health insurance is more sensitive to air pollution than life insurance and other types of insurance. In areas where NO2 and O3 are the main types of pollutants, air pollution has a greater impact on household insurance purchases.
