Spain adapts work practices to combat extreme heat with innovative sensors and early shifts

Spain is implementing new work practices to tackle the challenges posed by extreme heat, especially during summer months. On July 8, 2026, workers across the country are now equipped with innovative heat-monitoring wristbands, which alert them to rising body temperatures, as climate change intensifies heat waves.

In Barcelona, Antonio Reina, a public gardener, is one of the many outdoor workers using these wristbands. "It's an extra layer of security. As it's supposed to go off before you have symptoms, it lets you leave wherever your place of work is, drink water and get under the shade," Reina stated. These devices are part of a broader initiative by the Barcelona Town Hall, which distributed 1,400 of these wristbands to outdoor staff this year.

The need for such measures has become urgent following a recent heat wave, which resulted in numerous excess deaths and disrupted daily life. Workers in urban cleaning and construction have adjusted their schedules, starting earlier to avoid the hottest parts of the day. This proactive approach reflects Spain's long history of dealing with high temperatures.

Shifting Work Hours to Combat Heat

In Madrid, the extreme heat often surpasses 38°C (100°F). Eli de Sousa, a solar panel installer, explains, "We have to stop at 1 p.m. come what may, because it's impossible to work." His team begins work at 7 a.m. and has a small refrigerator with water on-site. If conditions become unbearable, they pause work and reschedule tasks for cooler days.

Juan Carlos Rodriguez, a telecommunications worker, highlights the importance of hydration and breaks. "We who work at height have to have the harness and all the equipment. So, obviously, the time comes when you need to get down, cool off and take off the harness," he emphasized.

Legislation and Worker Safety

Spanish law from the 1990s mandates a maximum temperature of 27°C (81°F) in closed workplaces. However, enforcement has been inconsistent, particularly in schools. Labor Ministry fines for heat-related infractions have surged from €706,419 in 2022 to nearly €1.6 million ($1.8 million) in 2023.

The tragic death of a street cleaner in July 2022 due to heatstroke sparked public outcry and led to new laws. Labor Minister Yolanda Diaz stated, "In the 21st century, no one should fall ill or die in their workplace." The 2023 legislation obligates employers to adapt work schedules to avoid outdoor tasks during peak heat exposure.

While construction and urban cleaning sectors have widely adopted these rules, compliance varies in other industries. A new "climate leave" allows workers to take time off during extreme weather events, although applying this during heat waves remains a challenge.

For many like Fernando Garcia, who runs an ice cream stall in central Madrid, the approach is simple: "Drink water, sprinkle yourself with water, and tough it out ... there's no other way." This sentiment captures the resilience of workers adapting to an increasingly challenging climate.
