The US military is an organization that is both physically and mentally demanding. The work requires service members to be in excellent shape and have high mental toughness.

According to a report by the Department of Defense, over 41 percent of service members said they experienced a physical health problem in the past year. The most common issues were back pain, joint pain, and headaches.

In addition to physical health problems, service members also face mental health challenges. A study by the National Center for PTSD found that about 15 percent of service members deployed to Iraq and Afghanistan met the criteria for PTSD.

However, even the most physically and mentally fit individuals face health challenges during military service. There are a variety of health risks that service members face, both on and off the battlefield.

Some of the most common health challenges faced by military personnel include:

1. Infectious diseases

Service members are at risk of exposure to various infectious diseases during deployments. These diseases can be spread through contact with contaminated food or water, close contact with an infected individual, or contact with contaminated surfaces.

Besides infectious diseases, service members are also at risk for chemical and biological agents exposure. These agents can cause various health problems, including respiratory illnesses, skin irritation, gastrointestinal problems, and cancer.

Mesothelioma is a rare but aggressive form of cancer caused by exposure to asbestos. Military personnel is at an increased risk of developing mesothelioma due to the presence of asbestos in many older buildings on military bases.

In such a situation, it is crucial for military personnel to be vaccinated against common diseases and to follow basic hygiene practices. You can read more information about precautions against deadly cancer at and know about the available treatments.

2. Heat injuries

During the service, soldiers are often required to perform strenuous activities in hot weather conditions. This can lead to heat injuries, such as heat stroke and exhaustion.

The symptoms of heat injuries include dizziness, headache, nausea, confusion, and increased body temperature. If left untreated, heat injuries can be fatal.

In addition to heat injuries, service members also face the risk of cold injuries. These injuries occur when the body is exposed to cold temperatures for extended periods.

Common cold injuries include frostbite and hypothermia. Frostbite is tissue damage due to freezing, while hypothermia is the condition when the body temperature drops below 95 degrees Fahrenheit.

However, cold injuries can be prevented by dressing correctly for the conditions and taking breaks to warm up.

3. Traumatic brain injuries

One of the most common types of injury faced by military personnel is traumatic brain injury (TBI). A blow or jolt causes a TBI to the head that disrupts the brain’s normal function.

TBI can lead to various symptoms, including headaches, dizziness, confusion, memory problems, and mood swings. In severe cases, TBI can be fatal.

Military soldiers are at an increased risk of TBI due to their work. They may be exposed to blasts from improvised explosive devices or gunfire.

In addition, TBI can also occur due to falls, motor vehicle accidents, or sports-related injuries.

4. Stress and anxiety

Another common health challenge faced by military personnel is stress and anxiety. The service members are under a lot of pressure to perform their duties.

This can lead to various mental health problems, such as depression, anxiety, and post-traumatic stress disorder (PTSD).

Military personnel can manage stress and anxiety by practicing healthy coping mechanisms. Some helpful coping mechanisms include exercise, relaxation techniques, and journaling.

5. Depression

Although it may seem counterintuitive, military service members are at a higher risk of developing depression. This is due to the various stressors that come with the job.

These stressors include long hours, separation from family and friends, and exposure to dangerous situations.

Depression is a severe mental health condition that can lead to various problems. These problems include difficulty concentrating, fatigue, sleep problems, and thoughts of suicide.

If you are experiencing any of these symptoms, it is vital to seek professional help.

Military service members face many health challenges. However, these challenges can be managed by taking precautions and seeking professional help when needed.

6. Substance abuse

Substance abuse is another common health challenge faced by military personnel. The use of alcohol or drugs can lead to various problems, such as addiction, mental health problems, and legal issues.

Substance abuse can also lead to accidents and injuries. In addition, it can interfere with a service member’s ability to perform their duties.

Substance abuse is a severe problem that should not be taken lightly. If you or someone you know is struggling with substance abuse, it is necessary to seek professional help.

7. Post-traumatic stress disorder
