Analysis of the impact of urban summer high temperatures and outdoor activity duration on residents' emotional health: Taking hostility as an example

Abstract

The combined effect of global warming and the heat island effect keeps the temperature of cities rising in the summer, seriously threatening the physical and mental health of urban residents. Taking the area within the Sixth Ring Road of Beijing as an example, based on Landsat remote sensing images, meteorological stations, and questionnaires, this study established a relational model between temperature and hostility and then analyzed the changes in the emotional health risk (hostility) in the study area and the mechanism of how outdoor activity duration influences hostility. Results show that: (1) the area within the Sixth Ring Road of Beijing had a higher and higher temperature from 1991 to 2020. Low-temperature areas gradually shrank, and medium- and high-temperature areas extended outwards from the center. (2) The threat of high temperature to residents' hostility gradually intensified—the sphere of influence expanded, low-risk areas quickly turned into medium-high-risk areas, and the level of hostility risk increased. Level 1 risk areas of hostility had the most obvious reduction—a 74.33% reduction in area proportion; meanwhile, Level 3 risk areas had the most significant growth—a 50.41% increase in area proportion. (3) In the first 120 min of outdoor activities under high temperature, residents' hostility was negatively correlated with outdoor activity duration; after more than 120 min, hostility became positively correlated with duration. Therefore, figuring out how temperature changes influence human emotions is of great significance to improving the living environment and health level of residents. This study attempts to (1) explore the impact of temperature changes and outdoor activity duration on hostility, (2) evaluate residents' emotional health risk levels affected by high temperature, and (3) provide a theoretical basis for the early warning mechanism of emotional health risk and the planning of healthy cities.

Relationship between physical activity, sleep quality, and frailty in middle-aged and older adults: a cross-sectional study Running title: The correlation between physical activity, sleep quality, and frailty

“…PA in hot conditions increases the risk of Exercise Heat Stroke (EHS) (75) and affects β-activities in most areas of the brain(76). The prevalence of negative emotions increases signi cantly when a person is outdoors in the heat for more than 120 min (77). Older adults with hypertension or diabetes, when physically active for long periods in hot environments, may exhibit tremendous cellular stress, leading to cellular damage(78).…”

A review of nature-based solutions to environmental hazards through the lens of environmental justice

“…Increasing vegetation is one strategy to mitigate urban regional climate change and provide multiple ecosystem services (Jenerette et al 2011). However, the impact of vegetation on economic, water, and social fairness varies significantly between different communities and requires management through prudent environmental policies (Huang et al 2022). Additionally, the Birmingham government in the UK advocates incorporating the urban heat island into the scope of urban heat risk assessment, emphasizing the undeniable health risks associated with the urban heat island effect (Tomlinson et al 2011).…”

Is climate change affecting mental health of urban populations?

“…Examples are the Mediterranean region, Mashad (Iran), Delhi (India), Doha (Qatar), Abu Dhabi (UAE), Cairo (Egypt), Phoenix and Las Vegas (USA). Hot weather and extreme temperature are believed to worsen wellbeing and mental health, causing a worse night sleep due to higher night-time ambient temperature [22], depression [23], an increase in hostility [24], in suicide rate and hospitalization for mental conditions [25 ▪ ].…”
