PTSD and Sleep – 10 Reasons PTSD May Cause Problems Sleeping

People with PTSD may experience a number of different types of sleep problems. Many people with PTSD have difficulties falling asleep as compared to people without PTSD. In fact, one study of Vietnam veterans found that almost half of those with PTSD said that they have trouble falling asleep at night, whereas only 13% without PTSD said that they have this problem.

In addition, PTSD may make it difficult to stay asleep during the night. In the same study mentioned above, 9 out of 10 veterans with PTSD said that they often have trouble staying asleep during the night.

PTSD can cause problems getting to sleep and staying asleep. People with PTSD may wake up frequently during the night, have difficulty falling back asleep, or may wake up earlier than they intended.

PTSD can cause problems with quality of sleep. Also, even if sleep does occur, it is often not good, effective sleep (for example, there may be a lot of movement or talking/yelling during sleep).

10 Reasons People with PTSD may have Trouble Sleeping

Sleep has many purposes. The brain processes the previous day’s experiences and throughout the body numerous processes take place to repair the body as we sleep. The entire normal experience of sleep can become disrupted when one is experiencing PTSD.

Sleep problems are often one of the more difficult symptoms of PTSD to treat and the exact causes of these sleep problems in PTSD is not really well known. However, there have been some ideas.

1. Nightmares

Nightmares and “bad dreams” are very common among people with PTSD. Nightmares are considered one of the re-experiencing symptoms of PTSD. Among people with PTSD, nightmares may be about the traumatic event a person experienced or they may be about some other upsetting or threatening event.

It has been suggested that the nightmares of PTSD result in difficulties falling or staying asleep. Nightmares are frightening and upsetting and can disturb the process of sleep.

2. Afraid of Nightmares

The fear of having a nightmare also may cause a person with PTSD to resist going to bed feel afraid of going to sleep.

3. Sense a Nightmare Coming

As people experience more nightmares and resultant waking, the nightmares may actually begin to trigger waking in order to escape the arousal that goes along with having a nightmare.

4. Hyperarousal

Sleep problems among people with PTSD may also be the result of experiencing frequent symptoms of hyperarousal – constantly being on guard, tense, and on edge. A highly stressed nervous system and increased tension throughout the body can make it hard to relax and can interfere with one’s ability to fall and/or stay asleep.

5. Triggers

Night itself, or the act of falling asleep or waking up, may be triggers and cause terror/hyperarousal if a trauma occurred at night, when falling asleep, or when waking up (for example if someone experienced being raped at night).

6. Flashbacks

Sometimes flashbacks can occur at night and cause fear, inner turmoil and confusion.

7. Sounds

People with PTSD may be more sensitive to sounds while they sleep. They are strung tight and easily jump at any unusual sound. As a result, they may be more likely to wake up even in response to minor sounds.

8. Loss of Control

People with PTSD may also view going to sleep as a loss of control. The lack of awareness and control that comes with sleeping may be frightening for a person with PTSD, thereby further intensifying arousal and interfering with sleep.

9. Fears about Sleep

Because of all these sleep problems, people with PTSD often develop fears about going to sleep. They may experience worries or thoughts of their traumatic event as soon as they go to bed. They may also fear acting out their nightmares while asleep or impulsively upon being woken up from a nightmare, leading them to sleep alone away from their partners.

10. Problematic Cycle

Sleep problems connected with PTSD may lead to a problematic cycle. Because of a lack of sleep during the night, a person may sleep more during the day, leading to greater difficulties falling asleep at night.
