It’s a myth that waking a sleepwalker will cause them to have a heart attack, or another sudden health problem. However, that doesn’t mean you should wake a sleepwalker. Most experts agree that the best way to handle a sleepwalker is to carefully guide them back to bed. If you are unsuccessful, keep a careful eye on them and try again later. Sleepwalking occurs during a very deep stage of sleep which makes it difficult to wake someone easily. If a sleepwalker is awakened during this stage, it can cause severe disorientation and possibly agitation. Fortunately, sleepwalking is a fairly rare problem that tends to affect mostly children and adolescents and is usually outgrown by adulthood.
