Each year, as the summer months begin to approach and temperatures slowly begin to creep higher and higher, there never seems to be any shortage of news segments or articles reinforcing the dangers associated with exposure to extreme heat. Sports coaches are often encouraged to hold practices on days with low humidity while keeping a watchful eye on their players. Drivers are reminded to be attentive and refrain from leaving any passengers or pets in their hot cars. Individuals at high-risk, such as the elderly and ill, are asked to be extremely cautious, prompted to limit all unnecessary activity and take advantage of their air conditioners.

Often not as publicized, however, are the particular dangers unique to a certain extensive group of people— the men and women to which extreme heat exposure (as well as exposure to all other elements) is unavoidable because of their job.

This is called occupational exposure to heat, and believe it or not, there is a substantial amount of information available not only about how to limit the danger it presents, but prevent it altogether.

Though the illnesses and complications that accompany exposure to extreme heat are entirely preventable, heat is still responsible for the highest number of weather-related deaths in the United States every year. Over 600 people succumb to heat-related illnesses and injuries annually, and the actual number is estimated to be more than double that when heat as a contributing factor to death caused by a pre-existing illness is considered.

So what exactly does that mean for people exposed to heat on the job site? The unfortunate truth is that, especially considering neither hospitals nor health service providers are required to disclose heat-related illnesses to public health agencies, many statistics are still unknown— which is all the more reason to prepare as best as possible.

Keep Cool on the Job Site with These 6 Tips (and Learn About Why You Should)

#1 HYDRATE

There’s a reason we are told to drink plenty of
water when the going gets hot. Our bodies use
water in all of our cells, organs, and tissues in
order to keep our internal temperature regulated
and ensure we maintain the ability to function.
As a result, a lack of water can result in severe
complications. It’s suggested that workers doing
regular activity in hot situations drink 8 oz. of
water every 15-20 minutes. For prolonged or
excessive activity, sports drinks are encouraged
in order to replace lost electrolytes.

#2 WEAR REFLECTIVE AND
HEAT-ABSORBING CLOTHING 

All clothing interferes with heat loss from the
skin, so it’s important to be wise about clothing
choices in extreme heat. Thin, breathable clothing
that reflects the sun’s rays like hi-vis workwear
and clothing that is treated with a cooling surface or
can be altered (like dipped in water, for example)
to stimulate cooling are recommended.

#3 ACCLIMATE

Gradually and carefully exposing yourself to heat
can tremendously increase your ability to tolerate
it. Through an acclimatization process, your body
can (among many other things) actually improve
its ability to efficiently cool itself down through
natural processes, like sweating.

#4 GET SOME AIR

Air flow causes evaporative heat loss to increase,
meaning you can cool down at a faster rate. Make
sure your employer is outfitting your work space 
with air flow however and wherever is safely
possible.

#5 TAKE A BREAK (AND
THEN ANOTHER)

It is as important to keep cool as it is to not over
exert yourself when working in severe heat,
especially if you suffer from any illnesses or
ailments. Frequent rest breaks give your body
a chance to recover from extra heat and are
encouraged by the CDC.

#6 BE AWARE

Remember: Heat exhaustion, heat stress, heat
stroke, and several other heat-related complications
can be prevented. One of the most important things
you can do to prepare is be aware— knowledge of
prevention techniques will not only help you, but
might just help others as well.
