Heat-Related Health Risks for People Experiencing Homelessness: A Rapid Review

Extreme heat poses a significant public health threat for people experiencing homelessness (PEH), who face heightened risks due to prolonged outdoor exposure and limited access to resources. This rapid review synthesizes research from the past five years on the health impacts of extreme heat for PEH in high-income countries. A total of 11 studies were identified through a systematic search of multiple databases, focusing on publications from 2019 to 2024. The review highlights key vulnerability factors, including demographic characteristics, pre-existing health conditions, and geographic disparities, that increase heat-related health risks for PEH. Physical health impacts, such as heat-related morbidity and mortality, are common, alongside mental health and substance use disorders exacerbated by heat exposure. The review also highlights a significant increase in emergency department visits among PEH during heat events, emphasizing the additional burden on healthcare systems. Barriers, including limited physical and social access to cooling centers, water insecurity, and stigma, further compound these challenges. Addressing the unique vulnerabilities of PEH is crucial to reducing their risks during extreme heat events. Improving housing access and stability is essential as a long-term strategy to decrease homelessness and reduce heat stress in this vulnerable population. The review also underscores the need for inclusive interventions such as accessible cooling centers with targeted programming, regular access to water, and tailored healthcare services to meet the needs of PEH. Future research should focus on long-term studies to assess potential cumulative heat exposure effects and evaluate the effectiveness of interventions aimed at mitigating extreme heat impacts on PEH, while applying an intersectionality lens to explore how factors like race, gender, and age shape vulnerabilities and potential intervention strategies.

Endocrine effects of heat exposure and relevance to climate change

Climate change is increasing both seasonal temperatures and the frequency and severity of heat extremes. As the endocrine system facilitates physiological adaptations to temperature changes, diseases with an endocrinological basis have the potential to affect thermoregulation and increase the risk of heat injury. The effect of climate change and associated high temperature exposure on endocrine axis development and function, and on the prevalence and severity of diseases associated with hormone deficiency or excess, is unclear. This Perspective summarizes current knowledge relating to the hormonal effects of heat exposure in species ranging from rodents to humans. We also describe the potential effect of high temperature exposures on patients with endocrine diseases. Finally, we highlight the need for more basic science, clinical and epidemiological research into the effects of heat on endocrine function and health; this research could enable the development of interventions for people most at risk, in the context of rising environmental temperatures.

Health status of women affected by homelessness: A cluster of in concreto human rights violations and a time for action

Health problems of women experiencing homelessness are driven either from the usual background characteristics of this population, or from the homeless lifestyle. Apart from poverty and unemployment, transition to homelessness is often associated with substance abuse, history of victimization, stress, poor mental health and human immunodeficiency virus (HIV). Water insecurity can undermine bodily hygiene and dental health, posing a greater risk of dehydration and opportunistic infections. Exposure to extreme environmental conditions like heat waves and natural disasters increases morbidity, accelerates aging, and reduces life expectancy. Nutrition-wise, a high prevalence of food insecurity, obesity, and micronutrient deficiencies are apparent due to low diet quality and food waste. Poor hygiene, violence, and overcrowding increase the susceptibility of these women to communicable diseases, including sexually transmitted ones and COVID-19. Furthermore, established cardiovascular disease and diabetes mellitus are often either undertreated or neglected, and their complications are more widespread than in the general population. In addition, lack of medical screening and contraception non-use induce a variety of reproductive health issues. All these health conditions are tightly related to violations of human rights in this population, including the rights to housing, water, food, reproduction, health, work, and no discrimination. Thus, the care provided to women experiencing homelessness should be optimized at a multidimensional level, spanning beyond the provision of a warm bed, to include access to clean water and sanitation, psychological support and stress-coping strategies, disease management and acute health care, food of adequate quality, opportunities for employment and support for any minor dependants.
