Emerging evidence demonstrates that elevated temperatures acutely worsen mental health symptoms and significantly increase the risk of heat related morbidity and mortality. For people living with schizophrenia, prolonged exposure to heat can exacerbate psychiatric symptoms, impair judgment and decision making, and reduce the ability to engage in protective behaviors such as increasing hydration, reducing clothing, improving ventilation, or seeking cooler environments. As a result, individuals with schizophrenia may experience higher rates of heat related illness. To date our understanding of heat exposure effects in individuals with schizophrenia remains incomplete, hindering the development of evidence-based strategies to protect them.\n\nThus, the primary objective of this exploratory study is to gather preliminary data on the effects of indoor overheating on physiological responses (core body temperature and cardiovascular function), cognitive performance (attention, working memory, and reaction time), and mood in adults with schizophrenia. Specifically, we will assess whether maintaining indoor conditions at the upper recommended temperature limit for older adults (26°C, 45% relative humidity \\[RH\\]; PMID: 38329752) is sufficient to mitigate physiological strain compared with exposure to a hot indoor environment (36°C, 45% RH) representative of non-air-conditioned homes during extreme heat events in individuals with schizophrenia. In both conditions, the individual will remain seated at rest while wearing light clothing (t shirt and shorts), with the exception of performing 15 minutes of stepping exercise (4-4.5 METS) each hour (excluding the lunch period) to reflect typical daily activities of daily living.",[71,72,73],"Heat Stress","Physiological Stress","Cognitive Change",[75,76,77,78,79,80,81,82,83,84,85],"Indoor overheating","Indoor temperatures","Heat wave","Thermoregulation","Schizophrenia","Heat strain","Heat vulnerability","Hyperthermia","Mental health","Thermal comfort","Physical activity","2026-04-20",{"date":88,"type":89},"2026-04-23","ACTUAL",{"date":91,"type":89},"2025-11-08",{"date":93,"type":65},"2027-07-01",{"name":5,"class":6},1]
