Staying Cool During Summer: Essential Tips for Construction Workers

As the temperatures rise, so do the risks on construction sites. Managing heat during the summer is a unique challenge that requires careful attention and proactive measures to ensure the safety and well-being of all workers. At Lyreco Intersafe, we understand the importance of creating a safe working environment, especially under extreme weather conditions. Here’s why managing heat on a construction site is critical and how you can stay safe and comfortable.

Understanding Heat Stress

Global heat statistics indicate a steady annual rise of 1 degree in Earth’s temperature, reaching record highs in 2023. Heat stress arises when the body struggles to regulate its internal temperature effectively. This is often triggered by a combination of factors, including physical exertion, high environmental temperatures, and elevated humidity levels, which collectively overwhelm the body’s natural mechanisms for dispersing heat.

The Effects of Heat Exposure

Heat exposure can have severe physical and psychological effects on construction workers. Physical effects include heat stress, heat stroke, heat rash, heat exhaustion, heat cramps, heat edema, hypertension, chronic kidney disease, respiratory problems, cardiovascular diseases, physical fatigue, dizziness, and increased sweating. Psychological effects can include a decline in mental performance, focus, visual perception, mental fatigue, delayed responsiveness, anxiety, impaired mental ability, anger, frustration, confusion, and depression.

Protecting Against Ultraviolet (UV) Radiation

UV radiation poses a significant risk due to prolonged exposure to the sun’s rays while working outdoors. Sun protective clothing, categorized based on its Ultraviolet Protection Factor (UPF) rating, is essential for safeguarding workers. UPF-rated garments, such as long-sleeved shirts, long trousers, and wide-brimmed hats, provide coverage for exposed skin. Polyester and nylon fabrics are particularly effective as they offer durability, high resistance to abrasion, and comfort. These materials are hydrophobic, meaning they repel moisture, which helps keep workers dry by wicking away sweat from the skin. Additionally, anti-odour and anti-bacterial finishes prevent the growth of bacteria that can cause unpleasant smells.

Essential Protective Gear

To further protect against sun exposure, construction workers should use:

  • Protective Clothing: UPF-rated long-sleeved shirts, trousers, and wide-brimmed hats.
  • Safety Glasses: Safety glasses with ‘smoke’ or ‘polarised’ lenses protect eyes from harmful UV rays and sun glare. Polarised lenses are especially beneficial for blocking glare when working near water or other wet surfaces.

Hydration and Cooling Measures

Staying hydrated is crucial, especially during hot summer days. Drinking ample water throughout the day prevents dehydration, a significant risk in such conditions. Using cooling accessories like towels, sleeves, and bandanas can offer much-needed relief from the intense heat and aid in evaporation. Taking breaks in shaded areas helps replenish energy levels, allowing workers to safely carry out their tasks. Starting the workday earlier when temperatures are cooler and scheduling breaks during the hottest part of the day can also mitigate the effects of the sun’s heat.

Fun Fact

Construction sites often endure significantly higher temperatures than the surrounding atmospheric conditions. The average temperature disparity at a construction site can range from 10°C to 15°C higher, depending on factors like the type of construction activity, location, and local climate conditions.


Managing heat on construction sites during summer is a crucial aspect of maintaining worker safety and productivity. At Lyreco Intersafe, we are committed to providing the necessary tools and guidance to help you stay cool and safe. By understanding the risks and implementing effective protective measures, you can ensure a safer and more comfortable working environment for all.
