In Spain, authorities and employers respond to extreme summer temperatures by combining earlier working hours with wearable heat-safety technology for people working outdoors. A report profiles Antonio Reina, who tends a public garden in Barcelona during hot weather and relies on a wristband designed to monitor heat exposure. The reporting describes how the devices provide reassurance by tracking conditions that can indicate when the risk of heat stress is rising. Alongside these safeguards, the approach emphasizes “early starts,” meaning many outdoor tasks begin in the morning before temperatures peak. This helps reduce time spent in the hottest conditions while still allowing essential outdoor services to continue. The overall strategy reflects a broader effort to keep daily work running during heatwaves while lowering the likelihood of heat-related illness for workers exposed to direct sun and high temperatures. The coverage focuses on practical measures—monitoring and scheduling—that help manage heat risk during summer shifts in cities such as Barcelona.
