Ah, summertime! While we all may be enjoying some outdoor fun in the sun, it’s important to remember that for many industrial and construction workers, the heat brings danger. Whether it’s around heat-generating machinery, under the scorching sun, or in stuffy areas with no ventilation; heat stress is a dangerous illness that can sneak up on you.
Heat stress causes dizziness, confusion, muscle weakness, cramps, vomiting, and fainting. Not exactly a recipe for a productive workday. (Learn more about heat stress and symptoms here.)
Not only are these symptoms dangerous on their own but when you’re on a worksite, the risks can escalate even further. Imagine trying to handle heavy machinery, carry hefty objects, or work at dizzying heights while feeling like a hot mess. Your risk of an accident increases.
And if you’re one of those brave souls who have to wear heavy protective gear while you work, your risk of heat exhaustion goes up, since you can’t simply take off you’re your gear to cool down.
So how does your body protect itself against heat stress? Your body regulations your internal core temperature through thermoregulation. Shivering and sweating are both mechanisms of thermoregulation. Sweating is the body’s main way of cooling off but while doing so it releases water and necessary electrolytes.
But heres the kicker: if the temperature in your environment is higher than your natural body temperature (98.8°F), your bodys natural defense mechanisms are simply not enough.
How do you protect yourself from heat stress?
First line of defense: control of the heat. Whenever possible, try to control the heat in your work environment. This could mean implementing ventilation systems, fans or air conditioning to move around stale air and bring in fresh, cool air.
Administratively speaking, all workers should have regular breaks in a cooler area where they can rehydrate and lower their body temperature.
New workers should be given some extra time to acclimate to working in the high heat, even experienced workers who have taken more than a week off should take some acclimation time. The body is incredibly resilient but needs time to adjust. Ease into the high heat activities to avoid any harsh consequences. Read more about acclimatization here.
Once you’ve done what you can to control the heat, then move onto these measures.
STAY HYDRATED. And I’m not just talking about chugging a gallon of water in one go. Nope, electrolytes like sodium and chloride need to be replenished. Electrolyte drinks are a great way to do that, but remember to consume them steadily throughout the day. Trying to replenish electrolytes all at once can do more harm than good. Read more about electrolytes here.
Don’t forget about protective clothing! Visors, cooling towels, cooling vests and sunshades can be little superheroes that keep the body cool and comfortable. Browse our cooling products HERE.
Lastly, if you’re working out in the sun – always make sure you have access to a shaded area. Trust us, being in direct sunlight can make the heat feel 10-15 degrees warmer. So take breaks or even work under the shade whenever possible to protect yourself from overheating.
Everyone should take heat stress seriously, regardless of experience. With the right engineering and administrative controls, coupled with protective clothing, proper hydration (drink those electrolytes!) and a shaded area—you’ll be ready to tackle your hot workday as safely as possible.
