How to Take Care of Workers During Heatwaves

Summer often brings long, sunny days and plenty of solar energy… but also extreme temperatures that can challenge the health and productivity of workers, especially in industrial environments. Heatwaves are more than just a seasonal inconvenience—they pose a real risk to people’s well-being and the continuity of operations.

At Magnovent, we believe that prevention and adaptation are key to protecting your workforce. That’s why we’re sharing practical, sustainable tips on how to take care of workers during heatwaves.

When ambient temperatures exceed 30 °C (86 °F), extra precautions must be taken. At 33 °C (91.4 °F) and above, the health risks increase significantly, especially during physically demanding tasks or when working outdoors. . The human body needs to work harder to regulate its internal temperature. If it fails, symptoms such as fatigue, dizziness, dry skin, muscle cramps, or even heatstroke may occur, which can be very serious.

Planning ahead, organizing work efficiently, and ensuring cool and safe working environments should be a priority for any company committed to employee well-being.

Daily planning adjustments can make the difference between a safe, productive day and a risky one. Key tips include:

• Avoid peak heat hours by rescheduling demanding tasks to early morning or late afternoon.
• Reduce prolonged sun exposure by rotating roles or alternating tasks.
• Encourage frequent breaks in shaded or air-conditioned areas, especially for physically demanding work.
• Schedule the most strenuous tasks during the coolest hours, rotate duties to limit heat exposure, and increase recovery breaks, ideally once per hour.

2. Condition the Workspaces

Workplace temperature directly affects worker performance, focus, and health. That’s why it’s crucial to design workspaces that can handle heatwaves efficiently and sustainably.

At Magnovent, we provide tailored solutions to optimize thermal comfort in industrial settings:

• Use efficient ventilation systems to enhance air circulation: Our large-volume, low-speed (HVLS) industrial fans move significant amounts of air, creating a continuous breeze that improves thermal comfort without lowering the actual temperature. This reduces heat stress and the risk of heatstroke while consuming very little energy—ideal for large warehouses and open spaces.

• Choose materials and structures that minimize thermal radiation, such as insulating panels or thermal blinds: Applying ceramic liquid coatings or thermal films helps block solar radiation and maintain more stable indoor temperatures. Our ceramic insulating paint reflects up to 95% of infrared rays, reduces surface temperatures by up to 20 °C (68 °F), and acts as an anti-condensation barrier. Thermal insulation enhances comfort, lowers cooling needs, and extends the lifespan of structures.

• Create air-conditioned break areas accessible throughout the day: These zones are crucial for helping workers lower their core temperature and maintain comfort. Our solutions apply bioclimatic design principles to regulate indoor temperatures with minimal energy use, using natural ventilation, solar shading, thermal inertia, and smart space zoning.

3. Hydration and Proper Gear

Prevention starts with the basics and is essential to keeping your workers safe throughout long, hot days:

• Provide easy access to drinking water: It’s recommended to drink a glass every 15–20 minutes, even without feeling thirsty.
• Evitar bebidas alcohólicas, muy azucaradas o con cafeína.
• Use lightweight, breathable, light-colored workwear made from materials that allow sweat to evaporate.
• Ensure sun protection: provide caps, sunscreen, and avoid direct contact with hot or reflective surfaces.

4. Technology for Well-Being

Beyond changing schedules or clothing, technical solutions can help regulate workplace temperature without skyrocketing energy costs. At Magnovent, we offer technology designed for both comfort and efficiency:

• HVLS industrial fans: Perfect for large areas, they move a high volume of air at low speed, improving thermal sensation with minimal power consumption.
• Efficient cooling systems: Built for industrial use, they combine power and energy savings using bioclimatic design.
• Thermal insulation and solar protection: Like our ceramic insulating paint, which reduces thermal loads and boosts energy performance on roofs, walls, and windows.

These technologies help maintain safe, comfortable, and sustainable work environments even during extreme heat, protecting both people and energy usage.

Heatwaves are not just a weather event, they’re a challenge to workplace safety and productivity. Taking care of your team isn’t just a legal responsibility; it’s a strategic move for health, engagement, and efficiency.

At Magnovent, we help you create more comfortable, safer, and more human workspaces. Because a well-conditioned environment is also a way of caring for the people who work in it.
