Sleep is a weird thing when you think about it. Most of us just climb into bed, fall asleep, and wake up feeling (hopefully) refreshed. But for some people, it’s not that simple—especially if sleepwalking is involved.

Sleepwalking can be pretty harmless, like sitting up in bed or mumbling a few words. But in more extreme cases, people can get up, walk around, even cook food or step outside—all without realising it. So what’s going on here? And is there anything that can help?

At Devon Duvets, we’re all about better sleep. In this blog, we’re looking into what causes sleepwalking and whether things like a better sleep environment—think natural bedding that helps regulate temperature—could actually make a difference.

What is sleepwalking?

Ever woken up to find out you did something in your sleep—like talking, walking around, or even cooking? That’s sleepwalking, or somnambulism. It happens when part of the brain wakes up during deep sleep, but not all of it. So, a person might move around and even do things, yet have no clue it’s happening.

Kids are more likely to sleepwalk, but adults aren’t off the hook—especially if they’re stressed, exhausted, or have other things messing with their sleep.

For some, it’s as small as sitting up and looking around. Others take it further, walking, talking, or even doing things like making food or, in rare cases, driving. And the weirdest part? By morning, they don’t remember a thing.

What causes sleepwalking?

Several factors contribute to sleepwalking, including:

  • Genetics: Studies show that sleepwalking runs in families. If one parent sleepwalks, their child has a 45% chance of experiencing it too. 
  • Sleep deprivation: Lack of quality sleep can trigger sleepwalking episodes.
  • Stress and anxiety: High levels of stress disrupt deep sleep cycles, increasing the likelihood of sleepwalking.
  • Poor sleep environment: Uncomfortable sleeping conditions, including temperature fluctuations, can interfere with sleep cycles.
  • Alcohol and medication: Some substances affect the brain’s sleep patterns and can lead to sleepwalking episodes.

But is sleepwalking dangerous? And what can be done to manage it?

Is sleepwalking dangerous?

For most people, sleepwalking is harmless. However, in some cases, it can lead to injuries.

For example, some sleepwalkers trip over objects, fall downstairs, or even walk out of the house. In extreme cases, sleepwalkers have been known to drive while asleep, which can be incredibly dangerous.

To reduce the risks, creating a safe sleep environment and addressing underlying triggers is crucial.

How can your sleep environment help reduce sleepwalking?

Research suggests that sleep quality plays a key role in sleepwalking. Disruptions in sleep -such as overheating, discomfort, or noise - can increase the likelihood of sleepwalking episodes.

At Devon Duvets, we understand the importance of quality sleep, which is why we create bedding that:

  • Regulates temperature naturally: Preventing overheating and ensuring consistent, comfortable sleep.
  • Provides natural breathability: Our wool duvets promote airflow, reducing night-time restlessness.
  • Supports deeper, less interrupted sleep: High-quality natural bedding helps you fall into a deeper, more restorative sleep, reducing night-time disturbances.

A comfortable, temperature-controlled sleep environment may not cure sleepwalking, but it can help minimise sleep disruptions, which is one of the key triggers.

Frequently asked questions about sleepwalking

To help answer the most common questions people search for about sleepwalking, we’ve put together this Q&A.

1. Why do people sleepwalk?

Sleepwalking happens when the brain is in a state between deep sleep and wakefulness. The body moves, but the conscious mind remains asleep. It can be triggered by genetics, stress, sleep deprivation, or an uncomfortable sleep environment.

2. Can sleep deprivation cause sleepwalking?

Lack of sleep is one of the biggest triggers for sleepwalking. When someone is sleep-deprived, their deep sleep cycles become unstable, increasing the likelihood of sleep disturbances like sleepwalking.

3. Can stress and anxiety make sleepwalking worse?

Absolutely. Stress and anxiety disrupt sleep patterns, causing irregular sleep cycles. When sleep is disrupted, episodes of sleepwalking become more frequent. Practising relaxation techniques, such as breathing exercises or meditation before bed, can help improve sleep quality and reduce stress-related sleepwalking.

4. Does sleeping in a cooler room help prevent sleepwalking?

A comfortable sleep environment plays a crucial role in preventing sleepwalking. Overheating or discomfort during sleep can cause more frequent awakenings, increasing the risk of sleepwalking. Natural bedding, like wool duvets from Devon Duvets, helps regulate body temperature, providing a stable and comfortable sleep environment.

5. How can I make my bedroom safer for someone who sleepwalks?

If someone in your home sleepwalks, consider these safety measures:

  • Remove obstacles and sharp objects
  • Make sure doors and windows are safe 
  • Use baby gates at the top of stairs to avoid falls
  • Ensure bedding and sleepwear are comfortable and temperature-regulating

6. Can certain foods or drinks trigger sleepwalking?

Alcohol, caffeine, and heavy meals before bed can all interfere with deep sleep, making sleepwalking episodes more likely. Reducing stimulants before bedtime and maintaining a healthy, consistent sleep routine can help.

7. Is sleepwalking dangerous?

Sleepwalking itself is not harmful, but it can become dangerous if the sleepwalker trips, falls, or leaves the house. If sleepwalking is frequent or risky, consult a sleep specialist for further evaluation.

8. How can I stop sleepwalking?

There is no single "cure" for sleepwalking, but you can take steps to reduce episodes:

  • Get enough sleep by avoiding sleep deprivation
  • Reduce stress through trying meditation or relaxation techniques before bed
  • Optimise your sleep environment by using breathable, temperature-regulating bedding
  • Avoid alcohol or stimulants before bed
  • Stick to a consistent sleep schedule

Better sleep, fewer sleepwalking episodes

Sleepwalking remains a fascinating and sometimes mysterious condition, but one thing is clear: the quality of your sleep plays a major role in managing it.

By creating a sleep-friendly environment, reducing stress, and ensuring comfortable, temperature-regulated bedding, you can support deeper, more restorative sleep - which may, in turn, help reduce sleepwalking episodes.
