Sleepwalking is a sleep disorder. Your child will rise from bed and walk or engage in other activities that they would normally do when they are awake. They eyes will be open but they will appear to be in a dream-like state, and will probably not answer when you talk to them, although they may carry out conversations. Sleepwalking can last a few seconds, a few minutes, or more.
Sleep walking can be an indication that certain parts of the brain may not be relaxing properly at bedtime. It can be caused by illness or fever, tiredness, stress or anxiety. It is thought to occur in the beginning, slow-wave stages of non-rapid eye movement sleep before dream sleep. It may be related to the lack of magnesium(镁), and it is very possible that hormonal (荷尔蒙) changes in body could cause it. Certainly a child is more likely to be a sleepwalker if one of his parents suffered, too.
Sleepwalking itself is not dangerous and is generally not a sign of any more worrying problems. But if your child sleepwalkers regularly, you have to take safety measures to make sure that he doesn’t hurt himself while sleepwalking. Make sure that any doors can’t be opened by a child, and lock doors to the cellar (地下室), kitchen and other dangerous places. Check each night before lights go out for sharp objects or, indeed, anything on the floor which your child could trip over or hurt himself on.
A child may sleepwalk once and never sleepwalk again. Others may sleepwalk once a month or so. Still others may sleepwalk almost nightly. If you are worried you should consult your doctor.
