Whether you’ve been dealing with sleep disturbances for years or recently began experiencing troubling symptoms, the sleep disorder called exploding head syndrome (EHS) can be extremely frightening and disruptive. While the cause is still largely unknown, and little medical research has been conducted on it, current theories offer some insight into what may trigger EHS episodes – find out more here.

What is exploding head syndrome?

Exploding head syndrome was initially described in 1876; however, it was not officially classified as a sleep disorder until 2005. EHS is considered parasomnia, a disruptive type of sleep disorder in the same category as sleepwalking and sleep terrors. 

While it may sound like the title of a sci-fi movie, exploding head syndrome is an actual medical condition that causes loud noises in your head when falling asleep or waking up. These noises range from scary imaginary explosions to claps, bangs, roars, screeches, gunfire sounds, and more. Even if this phenomenon isn’t as widely discussed as other sleep conditions, such as narcolepsy or insomnia, many people suffer from it but don’t know its name. 

Experts say, “These events occur during the wake-sleep/sleep-wake transition period and generally last less than a second. Events are often accompanied by flashes of light and patient distress, but there is no significant associated pain.”

While it sounds painful, it’s good to understand that other than disturbing sleep and perhaps causing emotional distress, the jarring noises aren’t real and do not cause physical harm to the person experiencing them or anyone nearby. 

Thankfully, the prevalence of EHS is relatively low. About 10 percent of people may experience this at least once in their lifetime. However, some encounter the symptoms sporadically.

Symptoms of exploding head syndrome

While there aren’t many symptoms, the ones that occur can be frightening and confusing, especially when experiencing them for the first time. 

To become diagnosed with exploding head syndrome, someone must meet all of the following criteria, according to the International Classification of Sleep Disorders. 

1. Complaints of loud noises or sensations that mimic the effects of an explosion in the head during transition periods between sleep and wakefulness.

2. Feelings of intense arousal, and possibly fright, following these episodes.

3. No significant physical pain during or following the episodes.

Others may encounter flashes of light and twitching muscles. Overall, the experience only lasts about one second, although people might feel like it was longer. Although there are hypothesized causes, there is no single known cause for this sleep disorder. 

Can exploding head syndrome occur while awake?

Simply put, no, exploding head syndrome does not occur while awake. Because these episodes happen during the transition between sleeping and waking, to many, it seems as if they experience EHS while awake. The symptoms of the sleep disorder are what rouse people to wake up, often startled and confused. 

Conclusion

If you’ve ever woken up to a loud noise that seems to be coming from inside your head, you may have experienced exploding head syndrome. Although it can be frightening, especially if you’ve never experienced it before, exploding head syndrome is not harmful.

Do you experience loud explosions in your head just as you are fading off to sleep? Are these episodes accompanied by flashes of light and intense fear? If yes, then you may have exploding head syndrome (EHS). While researchers hypothesize why this strange sleep disorder occurs, there is no simple explanation as to why about 10% of the population experience it at one point in their lives. This unexplained phenomenon can be highly distressing for those affected. But the good news is that there are steps you can take to help stop EHS from occurring and get some much-needed restful sleep. 

How to know if you have exploding head syndrome

Exploding head syndrome is a type of sleep disorder that occurs suddenly, either when you are beginning to fall asleep or when you wake up in the middle of the night. This sleep disorder is characterized by hearing a loud noise or crashing sound in your head, which is not authentic or heard by anyone else. Along with the sound, EHS can also cause the patient to see flashes of light and experience muscle spasms. Unlike the name suggests, these episodes are not painful.

According to the International Classification of Sleep Disorders, the following criteria are symptoms someone must experience to be diagnosed with exploding head syndrome. 

1. Complaints of loud noises or sensations that mimic the effects of an explosion in the head during transition periods between sleep and wakefulness.
2. Feelings of intense arousal, and possibly fright, following these episodes.
3. No significant physical pain during or following the episodes.

Fortunately, the entire episode only lasts one to two seconds, even though it can seem long to those who encounter them. 

If you think you may have exploding head syndrome, please seek a diagnosis with a licensed sleep specialist; do not simply assume this is what you are experiencing. Other medical conditions have these same symptoms. 

Available treatments for exploding head syndrome

As stated previously, a direct cause has not yet been connected to exploding head syndrome; however, there are a few theories researchers believe may be true, such as: 

• A temporary increase in the activity of your brain’s sensory neurons
• Damage or dysfunction in your inner ear structures
• Abnormal attention processing in your brain during the sleep-wake transition
• An aura that occurs before a migraine
• Side effects from suddenly stopping selective serotonin reuptake inhibitors 

While the FDA has officially approved nothing, some sleep specialists prescribe a few different medications known to treat the symptoms of EHS. These are topiramate, nifedipine, amitriptyline, and clomipramine, which are all used to treat other conditions. 

ConclusionAs an alternative or in addition to medication, people with EHS can do some things at home to help stop the disorder. Practice de-stressing techniques such as yoga, meditation, baths, or reading before bed. Keeping good sleep habits may also help reduce or stop the symptoms.

Ultimately, speaking to a sleep specialist before attempting any at-home remedy is wise. Be 100% sure EHS is what is going on and not something else more dire.  

Conclusion

Exploding head syndrome may not have one specific cause, but that doesn’t mean there aren’t any possible treatments to try to stop it from happening.
