Heat Stress Blog Post Featured Image
On a hot day, it's easy to feel sluggish and unproductive. But for construction workers, outdoor laborers, and others whose jobs require them to be active in the heat, that feeling can quickly turn into a safety hazard. In this post, we'll explore how to manage and prevent heat stress while working outdoors or in the sun.

As the weather gets warmer, it’s important to be aware of the dangers of heat stress. This can be a serious problem for workers in high temperatures, and can cause health problems, decreased productivity, and even death. In this blog post, we will discuss how to prevent and manage heat stress. We’ll cover topics such as risk factors, prevention measures, and treatment methods. 

What is heat stress?

Heat stress occurs when the body is unable to cool itself down. This can happen due to high temperatures, humidity, or physical activity. When the body is unable to regulate its temperature, it can lead to heat exhaustion, heat stroke, and other health problems.

Construction workers are particularly prone to heat stress due to the combination of physical activity, hot workplaces and protective clothing, as well as particular tasks such as welding. If left untreated, heat stress can lead to more serious health problems such as heat stroke which is a serious, potentially life-threatening condition that occurs when your body overheats. When your body temperature reaches 40 degrees celsius or higher, it begins to break down. This can lead to organ damage, coma, and even death. 

Risk factors for heat stress:

  • Being pregnant
  • Pre-existing medical conditions
  • Being overweight
  • Working in a hot environment
  • Advanced age
  • Some medications
  • Not drinking enough fluids

Symptoms of heat stress:

  • Nausea
  • Vomiting
  • Headache
  • Dizziness
  • Confusion.

 If you experience any of these symptoms, it’s important to seek medical help immediately.

Preventing heat stress at work:

  • Wearing light, loose-fitting clothing:  Clothing that is light in color and made from breathable fabric will help your body regulate its temperature.
  • Drinking plenty of fluids: Staying hydrated is crucial in hot weather. Drink fluids even if you’re not thirsty, and avoid drinks with caffeine or alcohol.
  • Avoiding strenuous activity during the hottest part of the day:If possible, schedule strenuous activities for cooler times of the day.
  • Taking frequent breaks in a cool, shady area:  When you’re working outdoors, take a break every 20 minutes or so to cool down.
  • Acclimating to hot weather gradually:  If you’re not used to working in the heat, start by spending a few minutes outside each day and gradually increase the amount of time you’re exposed to the heat.

Treating heat stress:

  • Removing yourself from the heat
  • Cooling down with a cool cloth or shower
  • Drinking plenty of fluids. 

Heat stress can be a serious problem, but it’s important to be aware of the risks and take steps to prevent it. By following these tips, you can stay safe and healthy in the heat.
