Rumor: Folk saying is that waking sleepwalkers is dangerous, which can cause sleepwalkers to fall into a coma or have a heart attack.
Truth: According to the National Sleep Commission, the truth is just the opposite: it is more dangerous not to wake sleepwalkers.
Not waking up may lead to accidental falls and other situations. If possible, guiding sleepwalkers back to bed is the best choice, but in most cases sleepwalkers do not listen to instructions and do not accept protection.
Professional advice from the National Sleep Council NSF: Using super-large decibels and sharp noise to wake sleepwalkers (keeping a safe distance from sleepwalkers) may successfully wake sleepwalkers.
NSF said that this method is better than shaking to wake sleepwalkers, because shaking may make sleepwalkers think they have been attacked and easily lead to involuntary violent resistance.
After waking up sleepwalkers, most people feel panic. We just need to comfort them calmly. This is just sleepwalking.
