FORT LEE, Va. — As Soldiers and Civilians, our professions inherently expose us to heat stress through outdoor work, training, uniforms and personal protective equipment. While eliminating heat illnesses entirely may be unrealistic, proactive training, education and preparation can substantially minimize serious or fatal cases.
As we continue to move through August and September, summer heat demands vigilance against dehydration and heat injuries.
Consistent water intake is crucial—don’t wait for thirst.
Leaders must enforce work-rest cycles, provide shaded breaks and monitor personnel for heat stress symptoms. Early recognition and prompt cooling/rehydration are critical to preventing serious illness.
Prioritizing heat mitigation maintains readiness and mission effectiveness.
Acclimatization to heat is paramount. This can be achieved through moderate exercise over two weeks, with most benefits occurring within the first five to seven days.
Acclimatization lowers core body temperatures. The body also becomes more efficient at producing sweat with acclimatization. This includes an earlier onset of sweating, a higher sweat rate and a greater sweat output, though, this in-turn increases fluid needs.
Leaders must prioritize acclimatization periods before intense activities.
Heat illnesses range in severity from dehydration and heat cramps to heat exhaustion, heat injury and, most critical, heat stroke.
Dehydration occurs with fluid loss exceeding intake, while heat cramps likely stem from electrolyte imbalance and dehydration.
Heat exhaustion is a cardiovascular event resulting from the heart’s inability to meet the demands of exercise and heat dissipation, often exacerbated by dehydration.
Heat injury involves organ and tissue damage, progressing to heat stroke when accompanied by central nervous system dysfunction—indicated by loss of consciousness, altered mental status or combative behavior—and requiring immediate cooling to prevent fatality.
Contrary to common belief, heat illness risk isn't limited to summer.
While proper fluid replacement is vital, it’s not the sole preventative measure. Factors like acclimatization, fitness, medications, recent illness, consumption of energy drinks and diet all contribute.
Water is the preferred rehydration source, with sports drinks being supplemental when combined with adequate meals for electrolyte replacement.
Summer heat poses risks for the entire family.
Parents, remember to prioritize your own hydration and well-being alongside your children. Be mindful of the signs of heat exhaustion—dizziness, headache, nausea—in both yourselves and your kids.
Seek shade or air conditioning during peak heat hours and ensure everyone drinks plenty of fluids. Don't hesitate to seek medical attention if symptoms worsen, as heat illness can escalate quickly.
Protecting your family from the heat is essential for a safe and enjoyable summer.
Vigilance, proper preparation and a comprehensive understanding of these factors are essential for minimizing heat illness risk and ensuring readiness.
