Summary
Active component service members experienced more heat stroke in 2012 than 2011. Recruit trainees and those in combat roles faced higher heat injury risks, highlighting the need for targeted prevention strategies.
Area of Science:
- Environmental Medicine
- Occupational Health
- Military Health
Background:
- Heat-related illnesses pose a significant risk to active-duty military personnel.
- Understanding trends and risk factors is crucial for effective prevention and treatment.
Purpose of the Study:
- To analyze the incidence and characteristics of heat stroke and other heat injuries among US military service members from 2008 to 2012.
- To identify demographic and occupational factors associated with increased risk.
Main Methods:
- Retrospective analysis of heat injury data from active component service members.
- Comparison of incidence rates across different demographic groups, branches, training statuses, and occupations.
- Examination of heat injury data from deployment in Iraq/Afghanistan.
Main Results:
- Heat stroke cases in 2012 (n=365) increased from 2011 but were lower than in 2008-2009.
- Higher heat stroke incidence rates were observed in males, those under 20, Marine Corps/Army members, recruits, and combat-occupational specialties.
- Cases of "other heat injuries" (n=2,257) decreased in 2012, with higher rates among females, and significantly higher rates among recruit trainees compared to enlisted members and officers.
- 6.5% of 1,060 heat injury events in Iraq/Afghanistan (2008-2012) were heat stroke.
Conclusions:
- Heat stroke and other heat injuries remain a concern in the military, with specific subgroups at higher risk.
- Recruit trainees and those in physically demanding or hot environments require focused heat injury prevention measures.
- Continued surveillance and targeted interventions are necessary to mitigate heat-related illness burden in service members.

01:22Burn Injuries
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:22Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:21Cellular Injury II: Classification
Cellular injury is any process that disrupts a cell’s ability to maintain homeostasis, leading to structural or functional changes. It is broadly classified based on etiology (cause) and mechanism of damage.Classification by EtiologyCellular injury may result from several causes. Hypoxic injury happens due to reduced oxygen delivery, most commonly from inadequate blood supply, such as arterial obstruction; for example, coronary artery thrombosis can cause myocardial infarction. Chemical injury...
02:45Responses to Heat and Cold Stress
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
01:25Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
