Can’t Sleep? Thank Your Parents

If you suffer insomnia, you may have inherited your inability to sleep from your mother and father. Researchers at Université Laval’s School of Psychology in Quebec have found that if another member of your family has insomnia, your chances of tossing and turning at night increase by 67 percent. And if three other members of your family are up at night, your risk of insomnia may go up by a startling 314 percent.

The research team at Laval looked at the sleep habits of more than 3,400 people in reaching their conclusions. They found that 40 percent of insomniacs had a family where at least one other person also suffered a sleep disorder.
