By Anne Harding

NEW YORK (Reuters Health) - Being woken up and exposed to bright light at night can throw off a person's biological clock for the next few days, a new study shows. What's more, the researchers found that being woken up at night at all--even in a dark room--also disrupts the body's timing, although to a lesser degree.

The wakening seem to introduce a "lag" into the body clock, pushing back the release of hormones and other body processes by as much as an hour and a half.

NEW YORK (Reuters Health) - Adults appear to have different sleepwalking traits from children, and some may have genetic reasons for engaging in nighttime rambling, according to new research.

In addition, one quarter of adult sleepwalkers had a family history of the behavior.
