As researchers at the Canadian Cardiovascular Congress in Montreal reported on the detrimental effects of lack of sleep on children on Tuesday，Brian McCrindle，a pediatric cardiologist at the Hospital for Sick Children in Toronto，said in an interview that one in five teenagers reports having poor sleep and regularly takes sleep medication.
