Do you sleepwalk—or do you know someone who does? Find out how to deal with sleepwalkers properly and what pets may have to do with it. 

Dr. Vorster, head of the Swiss Sleep House in Bern, explains how sleepwalking occurs in the first place: “When we sleepwalk, one half of the brain is in deep sleep while the other is awake. This phenomenon usually occurs toward the end of the first or second deep-sleep phase in the first half of the night.” Children between the ages of six and twelve are more frequently affected than adults. Not everyone wanders clumsily through the house with arms outstretched—contrary to how it’s often portrayed in movies, sleepwalkers do not walk with their arms extended. Simply sitting up in bed, mumbling during the night, or even just gesturing with the hands can already be considered sleepwalking. 

“Do not wake a sleepwalker; instead, gently guide them back to bed. If disturbed, they are pulled out of deep sleep, which can lead to disorientation, irritation, and even aggression.” — Dr. Vorster, sleep researcher, Swiss Sleep House Bern

Pets and allergies can trigger sleepwalking 

Sleepwalking can be triggered by both internal and external stimuli. Internal triggers include stress (also caused by irregular sleep or work schedules), snoring, the urge to urinate, and alcohol. External triggers include noise, light stimuli, and even a bed partner. Pets and allergies, among other factors, can also encourage these nighttime wanderings. Loud noises, stress, or certain medications can cause one half of the brain to wake up while the other half continues sleeping. 

Conclusion 

The fact is: sleepwalking can be dangerous under certain circumstances. Objects left lying around or stairs can quickly become tripping hazards. “Sleepwalking can be treated very effectively. It’s important to seek treatment if incidents become more frequent,” concludes Dr. Vorster. 

Sleep tip from Dr. Vorster

“If you are prone to sleepwalking, you should avoid alcohol, reduce emotional stress, and maintain a regular sleep schedule. If necessary, have your snoring treated.”
