“…Extreme heat poses a significant burden on the human body, profoundly impacting individuals' wellbeing and overall health. Prolonged exposure to high air temperatures can lead to dehydration, heat exhaustion, and, in severe cases, life-threatening heatstroke [60,61]. Furthermore, the discomfort caused by extreme heat can lead to sleep disturbances and reduced productivity among people in the affected areas [62,63].…”

In the summer of 2022, an intense heatwave swept through Northern Europe, with London bearing a significant impact. While nature-based solutions are often considered to be ideal responses to such heatwaves, experiences from the 2022 heatwave and others revealed potential drawbacks, particularly for urban green spaces. Prolonged dry spells, frequently accompanying heatwaves, result in excessively dry soil and the subsequent decline of vegetation in large parks. In the present study, microclimate simulations were conducted for Hyde Park in London, a location that experienced such drought during the 2022 heatwave, to examine its microclimatic performance in terms of thermal comfort and tree health. In alignment with the observations, ENVI-met could replicate the lack of noticeable cooling effects during the daytime and only marginal cooling during the nighttime. To address these challenges, mitigation scenarios were explored, incorporating heat mitigation measures such as part-time irrigation, temporary sun sails, and façade greenery. The findings demonstrated that implementing these measures could reduce heat stress by up to 13 K PET (physiologically equivalent temperature). These practical solutions emerged as effective remedies for mitigating the impact of heatwaves on urban green spaces and, hence, improving future urban development overall.

“…Shell temperatures are usually represented by measurements taken at various points on the skin (Tskin), which are more variable and susceptible to changes in the room/environmental temperature (Lim et al, 2008). In the current scenario of global warming, the development of medical technologies for measuring human Tinternal during daily activities, in a non-invasive manner and across different environments, becomes crucial to face heat-related illnesses (Ou et al, 2023). Among the medical technologies for measuring Tinternal, the ingestion of telemetric capsules to measure Tgastrointestinal have gained popularity .…”

Methods: Eight men and eight women, regular cyclists (Age: 33.9±8 years; VO2max: 53.6±7.0 mL.kg−1.min−1) underwent two similar cycling trials in a controlled environment at 32°C, relative humidity 60%. The protocol consisted of an initial 10-minute rest, followed by an exercise protocol (60 minutes) in a hot environment, comprising 10 minutes at 20% of maximal aerobic power, 25 minutes at 55%, and 25 minutes at 75%, with an additional 25 minutes of post-exercise recovery. Core temperature was recorded simultaneously every minute using a gastrointestinal capsule (TCAPSULE) and the CORE Sensor (TCORE). Bland–Altman analysis was performed to calculate bias, upper (LCS) and lower (LCI) concordance limits, and the 95% confidence interval (CI95%). The maximum acceptable difference between the two devices was ±0.4°C. A mixed linear model was used to model the paired differences between the two measurement systems, considering the subjects, reliability and environmental conditions as random effects and the activities as a fixed effect. Results: The CORE Sensor recorded an ICC value of 0.98. A non-significant bias value of 0.01, LCS of 0.38°C, LCI of -0.35°C and 95% CI of ±0.36°C were found. The Exergen TAT-5000 recorded an ICC value of 0.90. A significant bias value of -0.59, LCS of 0.82°C, LCI of -2.05°C and 95% CI of ±1.44°C were found. Conclusion: Compared to TCAPSULE, the CORE Sensor was considered valid and reliable in estimating core temperature during cycling exercise in a hot environment. Compared to TCAPSULE, the Exergen TAT-5000 was considered reliable but invalid in estimating core temperature during cycling exercise in a hot environment.KEYWORDS Body Temperature; Cycling Exercise; Heat Wave; Thermometers; Heat Illnesses.
