Teenagers who don’t get enough sleep are at higher risk of developing problems with alcohol compared with their peers who don’t drink, a new study suggests. The study used data collected from 6,500 teens who were part of a larger study on adolescent health, NPR reports. The researchers found teens ages 14 to 16 who had trouble falling or staying asleep were 47 percent more likely to engage in binge drinking than their peers who didn’t have sleep problems. Teens with sleep problems at the beginning of the study were 14 percent more likely to drive drunk and 11 percent more likely to have interpersonal issues related to alcohol one year later. After five years, those who had sleep issues in their teen years were 10 percent more likely to drive drunk.
