A study suggests that preschoolers whose natural preference is for going to bed and waking up on the late side are more likely to have sleep problems, reports Reuters.
“Sleep problems can start in early childhood and often persist across development. They have been associated with negative behavioral, cognitive, and emotional health consequences,” senior author Birit Broekman, a researcher with the Singapore Institute for Clinical Sciences, Agency for Science, Technology and Research, said in an email.
