Heat Stress Illnesses can affect workers working outdoors and also workers working in high heat indoor environments.
People that have to work under high heat stress environments are faced with dangerous conditions. For outdoor workers in construction, civil engineering, environmental engineering, transportation, farming & forestry industries, the annual record-breaking heat waves can bring broiling and unsafe working conditions. The extreme heat conditions affects many of the spots across the U.S. With the rising temperature patterns, some of the excruciating heat and high humidity conditions can last for months. According to OSHA “Heat is the leading cause of death among all weather-related and high heat workplace hazards. ” Workers that are working in high heat manufacturing environments, melting metal & glass, welding for the construction, automotive, and aerospace industries are also susceptible to heat related stress illnesses.
Each year, thousands of people are admitted to the emergency room due to heat strokes and heat stress related illnesses. When heat stress illness is left untreated, it can lead to death. Approximately 400 or more people die from heat strokes every year. If you are an employer it is vitally important that outdoor workers and indoor workers working in a high heat environment are prepared for even modest heat, but especially in extreme temperatures.
Of course, we all look forward to enjoying summer and the warmer weather. But when real heat sets in, it can create real hazards for workers. One of the biggest challenges in the workplace is managing heat stress. A big percentage of work-related incidents are caused by workers being exposed to too much heat for too long a period of time. And this is why it is important for individuals and employers to implement protocols and safety measures to reduce the number of such occurrences.
How to prevent heat stress at work is essential and being prepared is critical.

Preventing Heat Stress Illness
When working outdoors, or in any environment where you or others will be exposed to very high temperatures, it is always important to keep hydrated. Human bodies dissipate heat through radiation in the form of sweat. The more you sweat, the more you lose water. When you get dehydrated, you decrease your ability to sweat, thus, you overheat.
On the other hand, keeping your body cool will reduce your body’s need to sweat. So the best way to prevent heatstroke illness is really to do both. Remember to take breaks and stay in cool and shaded areas.
Here are some tips to keep in mind when working in high-temperature environments. For the best result do all of them:
- Drink cool water throughout the day. Preferably no reverse osmosis which has no balancing minerals
- Avoid sugary drinks and caffeine. If you drink electrolyte drinks, no sugar
- Wear ventilated clothing and avoid tight, heavy, or restrictive garments. Here are some examples.
- Wear wicking, evaporative apparel
- Wear a hat with a sun brim all the way around to protect your face and neck
- Wear a cooling cap under a hard hat
- Wrap a cool, damp towel on your neck or forehead
- Use economical heat-absorbing accessories while working (i.e. Cooling vests, cooling towels, bandanas, cooling shirts, etc.)
- Use a high quality, high factor, like SPF 50 - SPF 70+ sunblock with titanium dioxide, zinc oxide. Reapply every 2 hours if you're sweating or working outdoors.
- Take shade breaks. This allows your body to cool down and gives you time to assess the effects of exposure to heat
Of course, there will be situations where doing all those things mentioned above may not be enough. For that, listen to your body. If you feel tired, rest. Give yourself time to cool down. In the first instance that you feel something is wrong like you lose your focus, feel dizzy, nauseous, or weak, seek medical attention immediately.
