Abstract
This study investigates the impact of heat exposure on health outcomes among older adults in 10 Indian states, using data from the Longitudinal Aging Study of India (LASI-Wave I) and climate data from the National Oceanic and Atmospheric Administration (NOAA). Propensity score matching and ordered probit models were employed to control for demographic factors and isolate the effects of heat exposure. Our results show a significant association between heat exposure and worsening self-reported health and mental health, including increased feeling of depression, fatigue, fear, and decreased life satisfaction. The analysis indicates that access to cooling devices mitigates adverse health effects in rural areas, while access to onsite water benefits urban residents. These findings underscore the critical role of housing and environment factors in moderating the health impacts of heat exposure and suggest targeted interventions to protect vulnerable populations.
期刊介绍：
International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
