Working in the heat and humidity means more than just the need to stay hydrated because you get hot and sweaty. Some people sweat more than others so that in and of itself is not the best measurement of your level of hydration. Heat and humidity also affect your internal organs, specifically your heart, and how hard it has to work to keep your body cool.
If you
are a heart patient, older than 50, or overweight, you might need to take
special precautions in the heat. Always
check with your healthcare provider for specific guidance. Certain heart medications can exaggerate the
body’s response to heat. But, don’t just
stop taking your medications. It is
important to take them as prescribed, and take them when you’re supposed to do
so.
The
important thing is to plan ahead. Begin
to hydrate before you begin work, hydrate during work, and continue to hydrate
after work. Studies show that a good
rule of thumb is to drink half your body weight in ounces of water per
day.
Dress for the heat. Wear lightweight, light-colored clothing in breathable
fabrics such as cotton, or a newer fabric that repels sweat. Remember to wear a
hat and/or sunglasses.
Before you get started,
apply a water-resistant sunscreen with at least SPF 15, and reapply it every
two hours. Stay hydrated by
drinking plenty of water before, during, and after work.
Take regular breaks. Find some shade or a cool place, stop for a few minutes,
hydrate, and start again.
