Why Do We Sleepwalk?

Fact or fiction: Waking a sleepwalker is not a good idea? Read on.

There’s spaghetti in the bathroom sink, the laptop’s in the laundry basket, and please tell me that is not urine dripping down the refrigerator door.

Either a group of college kids took over the house for the night or there’s a sleepwalker on the loose. Sleepwalking, or somnambulism, is a disorder that happens when people do some activity besides snoozing while they’re still asleep. There are lots of potential causes of sleepwalking, from depression to overdoing it on the booze. But sleepwalking isn’t always disastrous, and sleep specialists have devised some different techniques to keep nighttime wandering to a minimum.

Sleepwalk This Way — Why It Matters

Sleepwalking is a kind of parasomnia that about 30 percent of American adults have sleepwalked at least once in their life, and about 4 percent have sleepwalked once or more in the past year. Besides snoozing and strolling, other telltale signs of sleepwalking include opening the eyes without seeming awake and saying nonsensical things. (Sleeptalking, anyone?) And while sleepwalkers usually do unremarkable things like fiddle with the covers, others have been known to drive a car, go Julia Child in the kitchen, or even have sex! Most sleepwalking episodes last about 10 minutes or less. But whether they mumble about fairies or drive across the country and back, sleepwalkers generally don’t remember anything about the episode once they wake up.

While most sleepwalkers are kids, adults can definitely take 2 a.m. strolls around the house, too. This latest study on sleepwalking found Americans are more likely to sleepwalk today than they did in the 1970s. That’s possibly because more Americans take antidepressants now than 30 years ago, and certain medications can make people more likely to sleepwalk. (It’s also worth noting that people who suffer from major depressive disorder are more likely to sleepwalk in the first place.)

Studies have found men tend to sleepwalk more often than women, and we’re a lot more likely to roam the house after midnight if someone else in the family does. Alcohol can affect sleepwalking behavior, too, so ditch that last martini to avoid nighttime prowling. Even lifestyle changes like psychological stress and switching up a sleep schedule can contribute to sleepwalking. A lot of the factors involved in sleepwalking may have to do with malfunctions in the GABA system, which prevents movement during sleep. Depending on how significant the problem is, there are some different strategies to combat sleepwalking.

Dangerous Dozing — The Answer/Debate

Despite the common wisdom that it’s dangerous to wake a sleepwalker, most sleepwalkers will just look pretty confused when someone rouses them. Still, for some people, sleepwalking poses more of a problem than just giving spectators a midnight laugh. In about 2 percent of cases, sleepwalkers will exhibit violent behavior, though the cause of the aggression still isn’t clear. Even for relatively peaceful sleepwalkers, wandering around the bedroom like a zombie can disrupt the sleepwalkers’ rest, not to mention their bedmates’ snooze-time.

But it’s not always necessary to seek treatment for sleepwalking, other than removing any dangerous objects in the sleepwalker’s path. When sleepwalking episodes are a result of other sleep disorders like sleep-disordered breathing, it’s important to treat those issues first. Some sleepwalkers may benefit from psychotherapy, which can help them resolve the psychological stressors contributing to the sleep disorder. Another possible treatment involves anticipatory awakenings, or waking the patient up right before their usual sleepwalking time for several nights in a row until they eventually lose the habit. (Sounds fun, right?) Hypnosis is also an option for treating sleepwalking and other parasomnias. (You are getting very sleepy… but stay still!)

If sleepwalking is a serious issue, consider seeing a doctor or a sleep specialist for personalized advice. Until then, throw on some Billy Joel and snooze away.
