Sleepwalking prevention devices: 5 worth a try for easier nights

By Jason Wooden, PhD | Updated July 2023

Over 8 million in the US and 7% of individuals worldwide sleepwalk which can put themselves and others at risk.   Fortunately, there are a variety of sleepwalking prevention devices designed to sound a alert when they get out of bed or to provide a simple barrier.

Your choices include gates, safety door locks, bedroom door alarms, motion sensors, and floor mat alarms.  It’s also important for sleepwalkers to get regular sleep and avoid known triggers.

Getting a sleepwalking prevention device may be more important than you think

As a parent of a former sleepwalker, I totally get why you’re looking for answers.

And it’s no surprise you’re curious about sleepwalking prevention devices since people have been known to do some of the most outrageous (and worrisome) things while asleep.

Maybe you’ve been awakened at night to find a spouse doing something odd in the kitchen and the following morning they have no memory of it.

Or perhaps, you have a child who gets up at night, shuffles into the hallway, and mumbles incoherently about random things…

Whether it’s an adult or a child, sleepwalking is a serious issue because they can unknowingly harm themselves or others.

Did you know that over 8 million people in the US are prone to sleepwalking?

Worldwide as many as 7% of individuals sleepwalk.

It’s more common in children than in adults.  In fact, close to 20% of kids in the 8 to 12 year old range are affected by it.

Nonetheless, sleepwalking from your bed to sleep on a couch downstairs is one thing, but what about someone who leaves the house?

And what about the stories of people sleepwalking to a kitchen and handling dangerous objects like knives?

From personal experience, I know how unnerving this can be.

It can ruin your sleep for sure if you’re on edge worried about what’s going to happen.

Why do people sleepwalk?

Before we get into the sleepwalking prevention devices, let’s talk about what we know.

Sleepwalking, also known as somnambulism, is when someone walks or does other complex things while asleep.  It’s an unusual state between wakefulness and sleep.

Normally, you go through different stages which include cycles of non-REM and REM sleep.  Non-REM is where deep sleep occurs.  In sleepwalkers the brain is triggered to rouse the body while still in a deep sleep.

The reasons this happens is not fully understood but some of the known risk factors and triggers are:

Genetics – it tends to run in families

Poor sleep – you’re more likely to sleepwalk if sleep deprived

Stress and anxiety – can be from life changes or other things going on

Changes – travel, sleeping in unfamiliar surroundings, too much noise or light

Other health issues – fevers, asthma, acid reflux, migraine headaches, underlying sleep disorders like sleep apnea, and other health issues

Mental health challenges – people with dealing with issues such as depression, neurological disorders, obsessive-compulsive disorder, panic attacks, or posttraumatic stress disorder have an increased risk

Alcohol – heavy drinking can increase your risk

Medications – Some meds may trigger sleepwalking in patients including antidepressants, antipsychotics, and beta-blockers

Sleepwalking prevention devices

Okay, if you’re thinking about trying out a sleepwalking prevention device, the thing to keep in mind is that they don’t directly treat sleepwalking.

Instead, most work by sounding an alert when someone is out of bed or as a physical barrier to keep them from wandering away.  Your options range from low-tech no-frills remedies to more sophisticated electronics.

As you consider the various options, a couple things to think about:

  • For alerts, who do you want to hear it, the sleepwalker or someone else?
  • Do you prefer a soft or loud alarm?
  • Do you need a quick low fuss setup or are you willing to spend the time needed to fine tune a more sophisticated device?
  • Some may work better for a kid than an adult

Depending on your specific situation, some options may work better for you than others, so don’t be afraid to experiment.

What else can I do beside sleepwalking prevention devices?

Sleepwalking prevention devices can be useful and make for better nights, but they shouldn’t be the only thing you do.

Since we know quite a bit about risk factors and triggers for sleepwalking, it’s important to address them as best you can.

Safety measures

You may need to adjust your living space to prevent an injury.  This can include relocating objects a sleepwalker can trip on or otherwise hurt themselves.

You may also need to block stairways and doorways with a gate, lock doors and windows, secure car keys, keep dangerous objects out of reach, or attach a bell to a door to sound the alarm.

Get regular sleep

Since being overtired is a known trigger, it’s important to get adequate sleep every night.  Start with improving your sleep hygiene which is everything you do during the day, evening, and at bedtime that can set the stage for quality sleep.

For better sleep hygiene, you should:
-maintain regular wake up & sleep times
-avoid naps
-avoid stimulants such as caffeine before bedtime
-maintain a bedtime routine
-keep your bedroom quiet, dark, and cool

They will also check for other health issues linked to poor sleep and sleepwalking.  This include things like asthma, fevers, heartburn, and heart problems.
