Heat Casualty Care and Preparation
Exertional Heat Illness in the US Navy
Exertional heat illness (EHI) is a serious condition that can occur when the body is unable to cool itself properly after strenuous activity. EHI can be life-threatening, and it is important to be aware of the signs and symptoms so that it can be treated promptly.
The US Navy has a high rate of EHI, with an average of 1,864 cases reported each year. The most common type of EHI in the Navy is heat exhaustion, which occurs when the body loses too much water and salt through sweating. Heat stroke is a more serious condition that occurs when the body's temperature rises to dangerously high levels.
There are a number of risk factors for EHI, including:
Dehydration
Overexertion
Hot weather
High humidity
Certain medications
Medical conditions such as heart disease, diabetes, and obesity
The Navy has a number of programs in place to prevent EHI, including:
Heat acclimatization training
Hydration education
Heat stress management plans
Personal protective equipment
If you are experiencing any of the signs or symptoms of EHI, it is important to seek medical attention immediately. These signs and symptoms include:
Headache
Dizziness
Nausea
Vomiting
Muscle cramps
Weakness
Confusion
Rapid heart rate
High body temperature
EHI can be treated with rest, fluids, and cooling measures. In more severe cases, hospitalization may be necessary.
By being aware of the risks of EHI and taking steps to prevent it, you can help to keep yourself and your fellow sailors safe.
Here are some additional tips to help prevent exertional heat illness:
Drink plenty of fluids, even before you feel thirsty.
Avoid alcohol and caffeine, which can dehydrate you.
Wear loose-fitting, light-colored clothing.
Take breaks from strenuous activity in the heat.
Stay in the shade or in an air-conditioned environment whenever possible.
Listen to your body and stop exercising if you feel any of the signs or symptoms of EHI.
