The term Post Traumatic Stress Disorder, commonly referred to as PTSD, was coined in 1980 by the American Psychological Association when it formally became recognized as a diagnosable condition after the Vietnam War. However, war did not create the condition itself. For as long as humans have lived and experienced traumatic events, whether it be battle, abuse, accidents, or a natural disaster, a psychological response has followed, even if we didn’t have a name for it.
A traumatic event is defined by a terrifying ordeal that a person has experienced, witnessed, or learned about, especially one that is life-threatening or causes physical harm. The experience causes that person to feel intense fear, horror, or a sense of helplessness. Traumatic events such as these put an individual under extreme stress. If this stress persists in an individual, it’s possible for their brain chemistry to be disrupted or even altered. It’s believed this disruption of the brain’s chemical makeup is what leads to the development of the psychological condition known as PTSD.
Symptoms of PTSD
There are three categories of symptoms associated with PTSD. If an individual experiences all three for longer than one month or any one of the symptoms cause distress that interferes with daily life, family, or work, then they may be diagnosed with PTSD.
1. Reliving the Event
Whether through recurring nightmares, intrusive flashbacks, or distressing memories, individuals with PTSD commonly re-experience the traumatic event on a consistent basis. These thoughts can cause extreme physical and emotional reactions.
2. Avoiding Reminders of the Event
Another common symptom of PTSD is emotional numbness or avoidance of certain places, people, thoughts, and activities that remind the individual of the trauma. Oftentimes, PTSD sufferers emotionally and/or physically withdraw from family, friends, and other responsibilities of daily life.
3. Being Constantly On Guard or Hyper Aroused
PTSD sufferers also tend to be highly aroused or on-guard at all times. This increase in arousal often leads to difficulty sleeping and concentrating, as well as, increased anger and irritability.
There are also a number of indirect symptoms related to PTSD. Some of these include drug abuse and the development of mental illnesses like anxiety or depression.
Other Reasons Individuals with PTSD Can’t Sleep
During REM sleep, the deepest stage of sleep where we experience dreams, our brain also processes memories and emotions. A nightmare is a disturbing dream often associated with negative emotions. The occasional nightmare is common in all people of all ages. However, some individuals, such as PTSD sufferers, experience nightmare on a consistent basis which causes distress, sleep deprivation, and ultimately a fear of going to sleep.
Interestingly enough, nightmares caused by traumatic experiences are somewhat different than your average, run of the mill, nightmare. Half of PTSD survivors experience nightmares that are exact replays of the traumatic event itself. The nightmares of PTSD survivors are also more likely to occur earlier in the night and in different stages of sleep compared to normal nightmares which typically take place during the second half of the night during REM sleep.
Chronic nightmares are often treated with Imagery Rehearsal Therapy (IRT), where a person whose having nightmares that upset them reimagines the ending of the nightmare while they are awake so that it no longer disturbs them. Replaying the nightmare with the “re-imagined” ending over and over while awake has been shown to reduce how often nightmares occur.
However, the same drugs PTSD sufferers turn to for release also cause sleep disorders. This is because drugs interfere with neurotransmitters, such as serotonin and norepinephrine, that help regulate sleep. Mistakenly, drug abusers turn to alcohol for sleep. But although alcohol is a depressant that’s thought as a sedative that makes you sleepy, it actually worsens your sleep quality and prevents you from entering deep, restorative REM sleep.
Although PTSD itself has been classified as a mental illness, it can also cause the development of other mental illnesses such as depression or anxiety disorder. There is a direct correlation between mental illness and sleep disorders. The most common sleep disorders associated with mental illnesses are insomnia (not being able to sleep) and hypersomnia (sleeping too much). The relationship between these two ailments varies in severity and complexity across different disorders. Yet, what researchers do know is that lack of sleep can worsen mental illness, making it more difficult for sufferers to cope with symptoms of their disorder.
Unfortunately, the symptoms of PTSD go further than the mind—research shows a connection between the psychological disorder and physical ailments such as pain. One reason PTSD and pain occur together is obvious: many traumatic events cause serious injuries that lead to chronic pain. The more traumatic the event, the more likely severe injuries occur and PTSD develops. But this isn’t the only reason PTSD is related to pain.
The second reason PTSD and issues with chronic pain occur simultaneously is that hyper-arousal, what we know to be as one of the most common symptoms of PTSD, can cause persistent muscle tension that leads to chronic pain. Pain makes it difficult to sleep. To fall asleep, your body must be relaxed; however, discomfort from pain prevents you from relaxing, making it difficult to fall asleep.

Cognitive Behavior Therapy for Insomnia
Also known as CBT-I, this method of therapy consists of frequent counseling sessions designed to discuss sleep problems and strategies for managing them. For example, IRT for nightmares. This type of therapy helps identify the connection between the mental health condition, in this case PTSD, and the sleep disorder.
This is a similar therapy to CBT in that it is discussion-based. However, psychotherapy is not solely focused on sleep. Rather, it’s designed for individuals to work through their traumatic experience and the anxiety it causes them. As these mental health issues, which are the root of the problem, are mended, healed sleep typically follows.
Since hyper-arousal often plagues PTSD victims, relaxation therapy works to help these individuals find a way to calm down. Although this takes regular practice, eventually, PTSD sufferers may be able to find a way to calm themselves down at night so they can fall asleep.
Sleep Hygiene Improvements
Sleep hygiene is just a fancy way of addressing your sleep habits and environment as a whole. Practicing good sleep hygiene means making sleep a priority, sticking to a bedtime, wind down at night, and creating a calming environment conducive for sleep. Sleep hygiene also incorporates the sleep products you use—having a supportive mattress, the correct pillows, and comfy sheets.
If you are suffering from troubled sleep, take a look at your sleep hygiene from a holistic point of view. Is your mattress contributing to your pain problem because it has lost its support? Is your room cool, quiet and dark? Are you avoiding blue-light from technology before bedtime? When mental health conditions that are out of your control impact sleep, do your best to make informed decisions about your environment that you can control.
See a Doctor
Many vets seek care in community medical settings with doctors that may not be aware of their military history. As a result, they may not inquire about PTSD and any other sleep-related issues. Therefore, anyone, vet or not, who are concerned they may have PTSD or insomnia needs to raise this issue with their physician. Seeking help from medical professionals is an important first step in managing the effects of this psychological disorder.
