Treating sleep apnea and PTSD together can improve overall health, as these two conditions often coexist and worsen each other’s symptoms.
Understanding the Link Between Sleep Apnea and PTSD
Post-traumatic stress disorder (PTSD) is a mental health condition that can follow a traumatic event, such as a natural disaster, car crash, or combat. About 7% to 8% of people experience this condition. While insomnia and nightmares are common, there is also a strong connection between this disorder and obstructive sleep apnea (OSA).
OSA occurs when breathing temporarily stops during the night, often leading to gasping, choking, or loud snoring. While 17% to 22% of the general population has OSA, the rate among those with PTSD ranges from 12% to 90%. This link is particularly evident in veterans; for example, 69% of Vietnam veterans with PTSD also had sleep-disordered breathing.
How Sleep Issues Affect PTSD Symptoms
Sleep problems are considered part of the disorder itself. When sleep is fragmented, the brain struggles to process emotions and memories, which can slow recovery. Specifically, REM sleep is vital for “fear extinction,” the process where the brain stops associating a neutral trigger with a fear response. Because many people with OSA experience their breathing lapses during REM sleep, this healing process is interrupted.
Furthermore, sleep-disordered breathing is linked to more severe ptsd symptoms, as well as a higher risk of:
- Depression and suicide
- Substance abuse
- Dementia
- Heart failure
- Certain types of cancer
Options for Treating Sleep Apnea and PTSD
Because these conditions have a bidirectional relationship, addressing one often helps the other.
CPAP Therapy
Continuous positive airway pressure (CPAP) is a primary treatment for OSA. A mask connected to a machine keeps the airways open. For those with both conditions, consistent CPAP use can reduce anxiety, depression, and nightmares. One study showed a 75% improvement in ptsd symptoms for those who adhered to the therapy, while those who did not saw symptoms worsen by 43%.
Other Interventions
- Weight Management: Weight loss programs or surgery may be recommended for overweight individuals.
- Oral Appliances: Mandibular advancement devices may be an alternative for those who find CPAP masks claustrophobic.
- PTSD Treatment: Talk therapy, medication, and cognitive behavioral therapy for insomnia (CBT-I) help manage the underlying mental health condition.
- Sleep Hygiene: Maintaining a cool, dark room, following a strict sleep schedule, and avoiding caffeine or alcohol before bed.
When to See a Doctor
Consult a healthcare provider if you have PTSD and notice the following warning signs:
- A partner reports that you snore loudly or stop breathing during sleep.
- You wake up choking or gasping for air.
- You feel exhausted even after a full night of sleep.
- You struggle to stay awake while driving, working, or at school.
FAQ
Does PTSD cause sleep apnea?
It is unclear which condition causes the other. However, they are closely linked; for every clinically significant increase in PTSD severity, a veteran’s risk of OSA increased by 40%.
How do sleep issues affect PTSD symptoms?
Poor sleep impairs mood and decision-making, which can make recovery harder and may lead to a lower likelihood of sticking to treatments like CPAP.
How to sleep better with PTSD?
Establish a calming bedtime routine, use white noise machines if sensitive to sound, and avoid stressors or screens an hour before bed. If you cannot fall asleep within 20 minutes, leave the bedroom to do a relaxing activity until you feel sleepy.
